Pennsylvania v. West Virginia (262 U.S. 553)/Opinion of the Court
These are suits, one by the commonwealth of Pennsylvania and the other by the state of Ohio, to enjoin the state of West Virginia from enforcing an act passed by her Legislature (Acts 1919, c. 71) which the complainants believe will largely curtail or cut off the supply of natural gas heretofore and now carried by pipe lines from West Virginia into their territory and there sold and used for fuel and lighting purposes. Although distinct, the suits are so much alike that they have been presented at the bar substantially as a single case. They will be dealt with accordingly in this opinion.

The West Virginia act is set forth at length in the margin.  The complainants challenge its validity on the ground that it directly interferes with interstate commerce and therefore contravenes the commerce clause of the Constitution of the United States (article 1, § 8, cl. 3), and they rest their right to relief on the grounds that to enforce the act will subject them to irreparable injury in respect of many of their public institutions and governmental agencies, which long have been and now are using this gas, and will subject them to further and incalculable injury, in that (a) it will imperil the health and comfort of thousands of their people who use the gas in their homes and are largely dependent thereon; and (b) will halt or curtail many industries which seasonally use great quantities of the gas and wherein thousands of persons are employed and millions of taxable wealth are invested.

The conditions out of which the suits have arisen and the facts material to their disposal are as follows:

Natural gas is found at pronounced depths in porous strata usually sand rock-constituting a natural reservoir, and is brought to the surface and reduced to possession through wells drilled into the containing strata. When a surface owner thus reduces it to possession he becomes its owner, and it becomes a subject of commerce, like any product of the forest, field, or mine. In the inclosing strata it is under great pressure, called rock pressure, which causes it to flow out rapidly when the strata are penetrated. If one surface owner drills wells and begins to draw off the gas, others desiring to exercise their common right must take the same course, for otherwise the g § under their lands may be drained out by those wells. After the gas is drawn from the inclosing strata there is no practicable mode of storing and holding it. It must be used promptly. Its chief use consists in producing heat and light by burning it. The points of use generally are in centers of population or of industry more or less remote from the places of production. The intervening transmission is effected through pipe lines. The normal rock pressure will carry the gas considerable distances and when that pressure wanes or is inadequate it can be supplemented by using compressors.

In West Virginia the production of natural gas began as much as 30 years ago and for the last 14 years has been greater than in any other state. The producing fields include 32 of her 55 counties. At first the gas was produced only in the course of oil operations, was regarded as a nuisance and was permitted to waste into the air. But it soon came to be regarded as valuable for heating and lighting, and the economy and convenience attending its use made it a preferred fuel. Its use within the state became relatively general, but was far less than the production, so the producers turned to neighboring states, notably Pennsylvania and Ohio, for a further market.

West Virginia sanctioned that effort. She permitted the formation under her laws of corporations for the purpose of constructing pipe lines from her gas fields into other states and carrying gas into the latter and there selling it; she also permitted corporations of other states to come into her territory for that purpose; and she extended to all these companies the use of her power of eminent domain in acquiring rights of way for their pipe lines. In no way did she then require, or assert any power to require, that consumers within her limits be preferred over consumers elsewhere. The effort to find a further market succeeded, and the gas came to be extensively carried into Pennsylvania as far as Pittsburgh, and into Ohio as far as Cleveland, Toledo, and Cincinnati. In that way the entire production was made of value to the producers. Landowners and lessees in the gas fields were greatly benefited and the taxable wealth of the state was largely increased. Approximately $300,000,000 were invested in the business-fully one-half in West Virginia. More than 7,000 miles of the pipe lines are in that state-2,000 miles being trunk lines.

Some of the pipe lines reach from the producing fields to the areas of consumption in Pennsylvania and Ohio. Some connect at or near the state line with others leading to the consuming areas. All are so operated that there is a continuous flow of gas from points of production to points of use. Branch lines divert some of the gas at intervening points, but without changing the general flow. Several lines cross and recross the state boundary repeatedly.

The pipe lines are all operated as public utilities, that is, in supplying gas to the public, and this is true in Pennsylvania and Ohio as well as in West Virginia. The lines long have been and now are supplying gas to the three states for use in their charitable, educational, and penal institutions, to their counties and municipalities for use in county, city, and school buildings, to local utilities serving particular communities, to the people generally in many cities and towns for use in their homes, places of business, and offices, and, in seasons when there is an adequate supply, to industrial plants for use in their operation. The predominant use is for fuel purposes; that for lighting being relatively small. All gas going into Pennsylvania and Ohio is carried and supplied under prior engagements respecting its disposal-most of it under long time contracts exacted or preferred by the purchasers or consumers.

Experience in other gas fields has shown that multiplied and prolonged drafts on the natural supply will exhaust it. Since 1916 it has been apparent that the older portions of the West Virginia fields are approaching exhaustion and that produc ion in those fields has reached and passed its maximum. The newer portions, however, in the judgment of informed operators, will make the fields commercially productive for several years more.

Latterly during the colder months-from November 1 to May 1 the combined needs of domestic and industrial consumers have been largely in excess of the production, and the pipe line companies generally have adopted and are pursuing the policy of preferring domestic consumers during those months. All the long-time contracts contain provisions admitting of such a preference. During other months, when there is little occasion for heating homes and offices, the needs of domestic consumers drop so materially that much gas may be and is supplied for industrial use without affecting the domestic use. But increased population, enlarged industry-particularly in West Virginia-and the advantages inhering in the gas as a fuel have finally resulted in a gross demand, which cannot be satisfied even in the summer months. The present actual consumption is all that the production will sustain. The pipe line companies cannot supply more gas in West Virginia without cutting down what they carry into Pennsylvania and Ohio; nor can they carry more into Pennsylvania and Ohio without cutting down what they supply in West Virginia. In short, the situation is such that to constrain the companies to supply more gas in any one of the three states necessarily will constrain them to supply less in the other two.

In 1918, 265 billion cubic feet of gas were produced in West Virginia, 38 billion were consumed within the state without becoming available to the public, and 227 billion became available in the hands of the pipe line companies. The companies supplied 70 billion to consumers in the state and carried 157 billion to consumers outside. They also brought 4 billion into the state from gas fields outside and to that extent enlarged the amount supplied to local consumers. Of that amount, 21 billion went into domestic use and 53 billion into industrial use. The major part of the gas carried into Pennsylvania went to industrial consumers, and the major part of that carried into Ohio went to domestic consumers.

The gas carried outside the state is sold for more than that used therein, but this naturally would be so, considering the additional pipe lines, compressors, and labor employed in the longer transmission. The proportion marketed beyond the state has not varied much. It now is practically what it was 10 years ago. Nor has there been any discrimination against consumers inside the state. They have been dealt with on the same plane as others. The companies have declined to quit the existing service to communities and consumers outside and to serve only those inside, but there is nothing invidious in this. It is in the line of fair treatment rather than discrimination.

The gas carried into Pennsylvania and Ohio, respectively, and there supplied to the state and her municipal agencies for strictly public use, is not negligible, but amounts to billions of cubic feet per year. It is the fuel with which food is cooked and water heated for thousands of dependents in charitable and penal institutions, with which hundreds of schoolhouses are heated and made comfortable for thousands of children, and with which municipal waterworks are operated in several cities, notably Cincinnati and Toledo. The heating and other appliances have been adjusted to its use, and to make the changes incident to substituting other fuel would involve an expenditure in each state of a very large sum of public money.

In Pennsylvania the gas is used by 300,000 domestic consumers caring for 1,500,000 people, and in Ohio by 725,000 domestic consumers caring for 3,625,000 people. This is where no other natural gas service is available. To change to other fuel would require an adjustment of heating and cooking appliances at an average cost of more than $100 for each domestic consumer, or an aggregate cost exceeding $30,000,000 in Pennsylvania  nd $72,500,000 in Ohio.

The act whose enforcement is sought to be enjoined was passed by the Legislature of West Virginia February 10, 1919, and went into effect May 11th following.  These suits were brought eight days thereafter, by direction of the Legislatures of the complainant states, and by leave of this court. Interlocutory injunctions were prayed and granted at the outset and are still in force.

Three questions bearing on the propriety of entertaining the suits were raised soon after the suits were begun, and consideration of them was postponed to the final hearing.

The first question is whether the suits involve a justiciable controversy between states in the sense of the judiciary article of the Constitution. We are of opinion that they do and that every element of such a controversy is present.

Each suit presents a direct issue between two states as to whether one may withdraw a natural product, a common subject of commercial dealings, from an established current of commerce moving into the territory of the other. The complainant state asserts and the defendant state denies that such a withdrawal is an interference with interstate commerce forbidden by the Constitution. This is essentially a judicial question. It concededly is so in suits between private parties, and of course its character is not different in a suit between states.

What is sought is not an abstract ruling on that question, but an injunction against such a withdrawal presently threatened and likely to be productive of great injury. The purpose to withdraw is shown in the enactment of the defendant state before set forth and is about to be carried into effect by her officers acting in her name and at her command. The state is the principal, and the action of her officers rightly may be imputed to her, even though a suit for an injunction might lie against them.

The attitude of the complainant states is not that of mere volunteers, attempting to vindicate the freedom of interstate commerce or to redress purely private grievances. Each sues to protect a twofold interest-one as the proprietor of various public institutions and schools whose supply of gas will be largely curtailed or cut off by the threatened interference with the interstate current, and the other as the representative of the consuming public whose supply will be similarly affected. Both interests are substantial and both the threatened with serious injury.

Each state uses large amounts of the gas in her several institutions and schools-the greater part in the discharge of duties which are relatively imperative. A break or cessation in the supply will embarrass her greatly in the discharge of those duties and expose thousands of dependents and school children to serous discomfort, if not more. To substitute another form of fuel will involve very large public expenditures.

The private consumers in each state not only include most of the inhabitants of many urban communities but constitute a substantial portion of the state's population. Their health, comfort, and welfare are seriously jeopardized by the threatened withdrawal of the gas from the interstate stream. This is a matter of grave public concern in which the state, as the representative of the public, has an interest apart from that of the individuals affected. It is not merely a remote or ethical interest, but one which is immediate and recognized by law.

In principle these views have full support in prior decisions, such as Missouri v. Illinois, 180 U.S. 208, 241, 21 Sup. Ct. 331, 45 L. Ed. 497, Id., 200 U.S. 496, 518, 26 Sup. Ct. 268, 50 L. Ed. 572; Kansas v. Colorado, 185 U.S. 125, 141-143, 22 Sup. Ct. 552, 46 L. Ed. 838; Id., 206 U.S. 46, 95-99, 27 Sup. Ct. 655, 51 L. Ed. 956; Georgia v. Tennessee Copper Co., 206 U.S. 30, 237, 27 Sup. Ct. 618, 51 L. Ed. 1038, 11 Ann. Cas. 488; New York v. New Jersey, 256 U.S. 296, 301, 41 Sup. Ct. 492, 65 L. Ed. 937; and Wyoming v. Colorado, 259 U.S. 419, 464, 42 Sup. Ct. 552, 66 L. Ed. 999. The defendant state relies on such cases as New Hampshire v. Louisiana, 108 U.S. 76, 2 Sup. Ct. 176, 27 L. Ed. 656; Louisiana v. Texas, 176 U.S. 1, 20 Sup. Ct. 251, 44 L. Ed. 347; Kansas v. United States, 204 U.S. 331, 27 Sup. Ct. 388, 51 L. Ed. 510; Oklahoma v. Atchison, Topeka & Santa Fe Ry. Co., 220 U.S. 277, 31 Sup. Ct. 434, 55 L. Ed. 465, and Texas v. Interstate Commerce Commission, 258 U.S. 158, 162, 42 Sup Ct. 261, 66 L. Ed. 531; but the facts on which they turned, as the opinions show, were so widely different from those here that they are not in point.

The second question is whether the suits were brought prematurely. They were brought a few days after the West Virginia act went into force. No order under it had been made by the Public Service Commission; nor had it been tested in actual practice. But this does not prove that the suits were premature. Of course they were not so, if it otherwise appeared that the act certainly would operate as the complainant states apprehended it would. One does not have to await the consummation of threatened injury to obtain preventive relief. If the injury is certainly impending, that is enough.

Turning to the act, we find that by its first section it lays on every pipe line company a positive duty-to the extent of its supply of gas produced in the state, whether produced by it or others-to satisfy the needs, whether for domestic, industrial or other use, of all intending consumers, whether old or new, who are willing to pay for the gas and want it for use within the section of the state in which it is produced, in that through which it transported, or in that wherein it is supplied to others. This is a substantive provision, whose terms are both direct and certain, and to which immediate obedience is commanded. No order of the commission is required to give it precision or make it obligatory, and it leaves nothing to the discretion of those who are to enforce it. On the contrary, it prescribes a definite rule of conduct and in itself puts the rule in force. It imposes an unconditional and mandatory duty, as counsel for the state admit, and obviously is intended to enforce a preferred recognition and satisfaction of the needs of consumers within the state, present and prospective, regardless of the effect on the interstate stream or on consumers outside the state.

The second section invests the commission with authority-on finding after notice and hearing that a company supplying gas for local needs is or probably will be without an adequate supply for the purpose-to order another company having gas in excess of what is required for its 'consumers within this state' to furnish the company whose supply is or will be inadequate with gas to make up the deficiency, or in the alternative to undertake itself to supply such local needs 'to the extent of such excess.' This provision, like the first, shows the purpose to give local consumers, present and prospective, a preferred status and to permit surplus gas only to be carried into other states.

The fourth section empowers the commission to entertain complaints by persons aggrieved or affected by any 'violation' of the act and to require that the violation be discontinued and the act obeyed, subject to a right of review in the courts, and also provides means of compelling obedience to the act pending the proceedings before the commission and until the decision on review.

Other sections contain penal and remedial provisions designed to make those just described effective. One in the fifth section declares that 'every day' during which any company, or any of its officers, agents or employees, 'shall fail to observe and comply with any order or direction of the commission, or to perform any duty enjoined by this act, shall constitute a separate and disti ct violation.' Another in the sixth section subjects any company violating the act to an action for damages by any one claiming to have been wronged by the violation.

We regard it as entirely clear that the act is intended to compel the retention within the state of whatever gas may be required to meet the local needs for all purposes, and that its procedural, penal and remedial provisions are amply adequate to accomplish that result. And we think it equally clear from the allegations in the bills now established by the evidence, that the situation when the suits were brought was such that the act directly and immediately would work a large curtailment of the volume of gas moving into the complainant states. Indeed, the conclusion is unavoidable that, with the increasing demand in West Virginia and the decreasing production, the act in a few years would work a practical cessation of the interstate stream.

It must be held therefore that the suits were not brought prematurely.

The third question is whether the requisite parties have been brought into the suits. It is objected that the pipe line companies have not been brought in. But there is nothing which makes their presence essential. The complainant states make no complaint and seek no relief against them. They are supplying gas in those states, and evidently will continue to do so, if not restrained or prevented by the defendant state. It is only with her that the complainant states are in controversy. It also is objected that the consumers in the defendant state who will be benefited if the act is enforced have no representation in the suits. But this is a misconception. They are represented by that state, and there is nothing in the situation requiring that they be specially represented or brought in. With equal basis it could be objected in a suit to prevent the enforcement of a statute reducing railroad freight rates, or in one to prevent the enforcement of a municipal ordinance reducing telephone or electric light rates, that shippers or users who would be benefited by the reduction must be specially represented or brought in. Such an objection would, of course, be untenable; and so of the objection here.

We turn now to the principal issue, whether a state wherein natural gas is produced and is a recognized subject of commercial dealings may require that in its sale and disposal consumers in that state shall be accorded a preferred right of purchase over consumers in other states-when the requirement necessarily will operate to withdraw a large volume of the gas from an established interstate current whereby it is supplied in other states to consumers there. Of course, in the last analysis, the question is whether the enforced withdrawal for the bene fit of local consumers is such an interference with interstate commerce as is forbidden to a state by the Constitution. The question is an important one; for what one state may do others may, and there are 10 states from which natural gas is exported for consumption in other states. Besides, what may be done with one natural product may be done with others, and there are several states in which the earth yields products of great value which are carried into other states and there used. But notwithstanding the importance of the question, its solution is not difficult. The controlling principles have been settled by many adjudications some so closely in point that the discussion here may be relatively brief.

By the Constitution (article 1, § 8, cl. 3) the power to regulate interstate commerce is expressly committed to Congress and therefore impliedly forbidden to the states. The purpose in this is to protect commercial intercourse from invidious restraints, to prevent interference through conflicting or hostile state laws and to insure uniformity in regulation. It means that in the matter of interstate commerce we are a single nation-one and the same people. All the states have assented to it, all are alike bound by it, and all are equally protected by it. Even th ir power to lay and collect taxes, comprehensive and necessary as that power is, cannot be exerted in a way which involves a discrimination against such commerce. Ward v. Maryland, 12 Wall. 418, 430, 20 L. Ed. 449; Welton v. Missouri, 91 U.S. 275, 280, 23 L. Ed. 347; Webber v. Virginia, 103 U.S. 344, 350, 26 L. Ed. 565; Coe v. Errol, 116 U.S. 517, 525, 526, 6 Sup. Ct. 475, 29 L. Ed. 715; Guy v. Baltimore, 100 U.S. 434, 442-443, 25 L. Ed. 743; Robbins v. Shelby Taxing District, 120 U.S. 489, 498, 7 Sup. Ct. 592, 30 L. Ed. 694.

Natural gas is a lawful article of commerce, and its transmission from one state to another for sale and consumption in the latter is interstate commerce. A state law, whether of the state where the gas is produced or that where it is to be sold, which by its necessary operation prevents, obstructs or burdens such transmission is a regulation of interstate commerce-a prohibited interference. West v. Kansas Natural Gas Co., 221 U.S. 229, 31 Sup. Ct. 564, 55 L. Ed. 716, 35 L. R. A. (N. S.) 1193; Public Utilities Co. v. Landon, 249 U.S. 236, 245, 39 Sup. Ct. 268, 63 L. Ed. 577; United Fuel Gas Co. v. Hallanan, 257 U.S. 277, 42 Sup. Ct. 105, 66 L. Ed. 234; Dahnke-Walker Milling Co. v. Bondurant, 257 U.S. 282, 290, 291, 42 Sup. Ct. 106, 66 L. Ed. 239; Lemke v. Farmers Grain Co., 258 U.S. 50, 42 Sup. Ct. 244, 66 L. Ed. 458; Western Union Telegraph Co. v. Foster, 247 U.S. 105, 38 Sup. Ct. 438, 62 L. Ed. 1006, 1 A. L. R. 1278; Minnesota v. Barber, 136 U.S. 313, 10 Sup. Ct. 862, 34 L. Ed. 455; Brimmer v. Rebman, 138 U.S. 78, 11 Sup. Ct. 213, 34 L. Ed. 862. The West Virginia act is such a law. Its provisions and the conditions which must surround its operation are such that it necessarily and directly will compel the diversion to local consumers of a large and increasing part of the gas heretofore and now going to consumers in the complainant states, and therefore will work a serious interference with that commerce.

But it is urged that there are special considerations which take the act out of the general rule and sustain its validity, even though there be an interference.

One of these is that the pipe line companies are engaged in supplying the gas to the public in West Virginia, that this is a quasi public business, and that the act does no more than require the companies to furnish a reasonably adequate service within reasonable territorial limits. It is true that the business is of a quasi public character, but it is so in Pennsylvania and Ohio as well as in West Virginia. The obligations inhering in it and the power to insist on an adequate service are the same in all three states. The supply of gas necessarily marks the extent of the service that can be rendered. Much of the business is interstate and has grown up through a course of years. West Virginia encouraged and sanctioned the development of that part of the business and has profited greatly by it. Her present effort, rightly understood, is to subordinate that part to the local business within her borders. In other words, it is in effect an attempt to regulate the interstate business to the advantage of the local consumers. But this she may not do. A direction to one of her railroads when short of facilities for moving coal to haul intrastate coal to the exclusion of interstate coal would not be different in kind or force.

Another consideration advanced to the same end is that the gas is a natural product of the state and has become a necessity therein, that the supply is waning and no longer sufficient to satisfy local needs and be used abroad, and that the act is therefore a legitimate measure of conservation in the interest of the people of the state. If the situation be as stated, it affords no ground for the assumption by the state of power to regulate interstate commerce, which is what the act attempts to do. That power is lodged elsewhere. A contention, in essence the same, was presented and considered in West v. Kansas Natural Gas Co., 221 U.S. 229, 31 Sup. Ct. 564, 55 L. Ed. 716, 35  . R. A. (N. S.) 1193, a case involving the validity of an Oklahoma statute designed to accomplish the retention of natural gas within the state. In the District Court the case had been heard on bill and answer, a proceeding in which the allegations of fact in the answer are taken as true. The hearing resulted in a decree adjudging the statute invalid and enjoining its enforcement. The decree was affirmed here. In the answer, as the opinion shows, it was alleged that physical conditions made it apparent that the gas field was of relatively short duration, that cities were near the field and their people needed the gas, that the state embodied only prairie land devoid of timber and there was no local fuel supply excepting coal and natural gas, that the production of coal was growing rapidly more costly, that 'substantially the only natural, practical, usable fuel, both for domestic and industrial use, is natural gas,' and that if pipe lines, such as the plaintiffs were intending to construct and put in operation, were permitted to carry gas into other states the supply would be speedily exhausted. Referring to these allegations and to a contention that the ruling principle of the statute was conservation of a needed natural resource, the court said (221 U.S. 255, 31 Sup. Ct. 571, 55 L. Ed. 716, 35 L. R. A. [N. S.] 1193):

The results of the contention repel its acceptance. Gas, when      reduced to possession, is a commodity; it belongs to the      owner of the land, and, when reduced to possession, is his      individual property subject to sale by him, and may be a      subject of intrastate commerce and interstate commerce. The      statute of Oklahoma recognizes it to be a subject of      intrastate commerce, but seeks to prohibit it from being the      subject of interstate commerce, and this is the purpose of      its conservation. In other words, the purpose of its      conservation is in a sense commercial-the business welfare of      the state, as coal might be, or timber. Both of those      products may be limited in amount, and the same consideration      of the public welfare which would confine gas to the use of      the inhabitants of a state would confine them to the      inhabitants of the state. If the states have such power a      singular situation might result. Pennsylvania might keep its      coal, the Northwest its timber, the mining states their      minerals. And why may not the products of the field be      brought within the principle? Thus enlarged, or without that      enlargement, its influence on interstate commerce need not be      pointed out. To what consequences does such power tend? If      one state has it, all states have it; embargo may be      retaliated by embargo, and commerce will be halted at state      lines. And yet we have said that 'in matters of foreign and      interstate commerce there are no state lines.' In such      commerce, instead of the states, a new power appears and a      new welfare, a welfare which transcends that of any state.      But rather let us say it is constituted of the welfare of all      of the states, and that of each state is made the greater by      a division of its resources, natural and created, with every      other state, and those of every other state with it. This was the purpose, as it is the      result, of the interstate commerce clause of the Constitution      of the United States. If there is to be a turning backward,      it must be done by the authority of another instrumentality      than a court.'

Finally, it is urged that this court cannot prescribe and execute regulations respecting the apportionment and use of the gas among the three states, and therefore that the bills should be dismissed. The conclusion does not follow from the premise. The object of the suits is not to obtain decretal regulations, but to enjoin the enforcement of the West Virginia act on the ground that it is an unconstitutional enactment and its intended enforcement will subject the complainant states to injury of serious magnitude. On full consideration, we reach the conclusion that the act is unconstitutional, that the apprehensions of the complainant states respecting the injur  which will ensue from its enforcement are well founded and that it obviously will operate most inequitably against those states. In this situation the appropriate decree is one declaring the act invalid and enjoining its enforcement. To dismiss the bills and leave the act to be enforced would be quite inadmissible. If there be need for regulating the interstate commerce involved, the regulation should be sought from the body in whom the power resides.

Decrees for complainants.

Mr. Justice HOLMES, dissenting.

The statute seeks to reach natural gas before it has begun to move in commerce of any kind. It addresses itself to gas hereafter to be collected and states to what uses it first must be applied. The gas is collected under and subject to the law, if valid, and at that moment it is not yet matter of commerce among the States. I think that the products of a State until they are actually started to a point outside it may be regulated by the State notwithstanding the commerce clause. In Oliver Iron Mining Co. v. Lord, 262 U.S. 172, 43 Sup. Ct. 526, 67 L. Ed. --, May 7, 1923, it was held that the State might levy an occupation tax upon the mining of iron ore equal to six per cent. of the value of the ore produced during the previous year, although substantially all the ore left the State and was put upon cars for that purpose by the same single movement by which it was severed from its bed. There could not be a case of a State's product more certainly destined to interstate commerce. It was put upon the cars by the same act by which it was produced. But as it was not yet in interstate commerce the tax was sustained. I know of no relevant distinction between taxing and regulating in other ways. McCulloch v. Maryland, 4 Wheat. 316, 431, 4 L. Ed. 579.

But the States have been held authorized to regulate in other ways more closely resembling the present. In Sligh v. Kirkwood, 237 U.S. 52, 35 Sup. Ct. 501, 59 L. Ed. 835, a state law was sustained that made it criminal to sell or offer for shipment citrus fruits that were immature or otherwise unfit for consumption. That, upon grounds of local policy, intercepted before it got into the stream, what would have been an object of interstate commerce. The local interest in the present case is greater and more obvious than in that of green oranges. Again, the power of the State to preserve a food supply for its people by game laws notwithstanding an indirect interference with interstate commerce is established. Geer v. Connecticut, 161 U.S. 519, 534, 16 Sup. Ct. 600, 40 L. Ed. 793; Silz v. Hesterberg, 211 U.S. 31, 42, 29 Sup. Ct. 10, 53 L. Ed. 75. If there is any difference between the property rights of the State in game and in gas still in the ground it does not concern the plaintiffs and it is plain from the decisions cited that they do not depend upon a speculative view as to title. See Missouri v. Holland, 252 U.S. 416, 434, 40 Sup. Ct. 382, 64 L. Ed. 641, 11 A. L. R. 984. The right of the State so to regulate the use of natural gas as to prevent waste was sustained as against the Fourteenth Amendment in Walls v. Midland Carbon Co., 254 U.S. 300, 41 Sup. Ct. 118, 65 L. Ed. 276, and I do not suppose that the plaintiffs would have fared any better had they invoked the commerce clause. I need do no more than refer to prohibition of manufacture of articles intended for export, such as colored oleomargarine, Capital City Dairy Co. v. Ohio, 183 U.S. 238, 245, 22 Sup. Ct. 120, 46 L. Ed. 171, or spirits. The result of that and other cases has been expressed by this Court more than once in the form of a general recognition of the right of a State to make 'reasonable provision for local needs,' Minnesota Rate Cases, 230 U.S. 352, 402, 410, 411, 33 Sup. Ct. 729, 57 L. Ed. 1511, 48 L. R. A. (N. S.) 1151, Ann. Cas. 1916A, 18; and the right has been recognized even when the interference with interstate commerce is direct, as when an interstate train is required to stop to accommodate passengers who do not leave the State, Lake Shore Michigan Southern Ry. Co. v. Ohio, 173 U.S. 285, 19 Sup. Ct. 465, 43 L. Ed. 702; Gulf, Colorado & Santa Fe Ry. Co. v. Texas, 246 U.S. 58, 38 Sup. Ct. 236, 62 L. Ed. 574.

I see nothing in the commerce clause to prevent a State from giving a preference to its inhabitants in the enjoyment of its natural advantages. If the gas were used only by private perons for their own purposes I know of no power in Congress to require them to devote it to public use or to transport it across state lines. It is the law of West Virginia and of West Virginia alone that makes the West Virginian gas what is called a public utility, and how far it shall be such is a matter the that law alone decides. I am aware that there is some general language in Oklahoma v. Kansas Natural Gas Co., 221 U.S. 229, 255, 31 Sup. Ct. 564, 55 L. Ed. 716, 35 L. R. A. (N. S.) 1193, a decision that I though wrong, implying that Pennsylvania might not keep its coal, or the northwest its timber, etc. But I confess I do not see what is to hinder. Certainly if the owners of the mines or the forests saw fit not to export their products the Constitution would not make them do it. I see nothing in that instrument that would produce a different result if the State gave the owners motives for their conduct, as by effering a bonus. However for the decision in the case referred to goes it cannot outweigh the consensus of the other decisions to which I have referred and that seem to me to confirm what I should think plain without them, that the Constitution does not prohibit a State from securing a reasonable preference for its own inhabitants in the enjoyment of its products even when the effect of its law is to keep property within its boundaries that otherwise would have passed outside. Hudson County Water Co. v. McCarter, 209 U.S. 349, 357, 28 Sup. Ct. 529, 52 L. Ed. 828, 14 Ann. Cas. 560.

I agree substantially with my brothers McREYNOLDS and BRANDEIS, but think that there is jurisdiction in such sense as to justify a statement of my opinion upon the meris of the case. I think that the bill should be dismissed.

Mr. Justice McREYNOLDS, dissenting.

It seems to me quite clear that the record presents no justiciable controversy; certainly none within the original jurisdiction of this court.

For the manifest purpose of protecting local consumers, West Virginia commanded her public service corporations not to transport natural gas beyond the borders of the state until they had satisfied the reasonable requirements of the people therein. Thereupon, complainants came here by original bills and alleged that if the statute were enforced they and their inhabitants could not obtain enough gas for their imperative demands from the divers pipe lines theretofore accustomed to supply them. They ask us to declare the enactment invalid because of conflict with the commerce clause of the federal Constitution and to restrain its enforcement. If the pipe lines hereafter fail to comply with their contracts, of course, they may be proceeded against in a proper forum; but to say that they probably will fail because of the statute and then to demand that the law-making power be enjoined is not to set up a real controversy cognizable in any court.

If West Virginia should prohibit the drilling of new gas wells, I hardly suppose complainants could demand an injunction here even if it were admitted that their supplies would be cut off. But who not, under the doctrine announced. Production has been permitted for years and appealing hardships would follow its cessation. And suppose West Virginia should repeal the charters of all her public service corporations now transporting gas and thereby disable them, could we interfere upon the demand of another state who claimed that she would suffer?

As originally adopted, the Constitution provided:

'In all cases affecting ambassadors, other public ministers      and consuls, and those in which a state shall be party, the      Supreme Court shall have original jurisdiction.'

Chisholm v. Georgia, 2 Dall  419, 1 L. Ed. 440, declared that a citizen of one state could proceed against another state by original action here. In Louisiana v. Texas, 176 U.S. 1, 20 Sup. Ct. 251, 44 L. Ed. 347, Mr. Chief Justice Fuller pointed out the character of controversies between states over which this court has original jurisdiction. With emphasis he declared that vindication of the freedom of interstate commerce is not committed to any state as parens patriae. Unless this ruling is to pass into the discard, it follows that neither of the complainants has any higher standing than one of her citizens with a contract for gas would have if there were no Eleventh Amendment. It is unnecessary to argue that the framers of the Constitution never intended to empower this court, at the suit of an individual, to enjoin a state from enforcing regulations prescribed for her own public service corporations. And yet, that possibility must be affirmed under the doctrine now announced.

Concluding his opinion in Chisholm v. Georgia (1793) Mr. Justice Iredell exclaimed:

'I pray to God that, if the Attorney General's doctrine, as      to the law, be established by the judgment of this court, all      the good he predicts from it may take place, and none of the      evils with which, I have the concern to say, it appears to me      to be pregnant.'

A like prayer seems not inappropriate here and now.

Mr. Justice BRANDEIS, dissenting.

The statement made by Mr. Justice HOLMES seems to me unanswerable. But, like Mr. Justice McREYNOLDS, I think that there are reasons why the bills should be dismissed without passing upon the constitutional question presented.

Natural gas in quantity is produced in 32 of the 55 counties of West Virginia. One-half of the inhabitants of that state have for years been dependent upon it for domestic uses, and it has been supplied to nearly 2,000 industrial establishments. Sixty-seven concerns are engaged in the business of distributing this natural gas to the public. Most of them are corporations organized under the laws of West Virginia. A few are organized under the laws of some other state. Some are unincorporated. Each had, prior to the Act of February 17, 1919, hereinafter referred to, been declared by statute to be a public service corporation,  endowed with the power of eminent domain. Each was under the common-law duty of furnishing to the public, throughout the West Virginia territory in which it does business adequate service, Carnegie Natural Gas Co. v. Swiger, 72 W. Va. 557, 79 S. E. 3, 46 L. R. A. (N. S.) 1073; Clarksburg Light & Heat Co. v. Public Service Commission, 84 W. Va. 638, 100 S. E. 551. And as to each this duty has been confirmed by the legislation of that state.

Prior to the World War the production of natural gas in West Virginia and the demand were such that large quantities could be exported by its public service corporations to other states without thereby lessening the ability of these concerns to give adequate service to their West Virginia customers. During the war the demand, both within and without the state, increased greatly, and thereafter the supply became smaller. Of the net supply of West Virginia natural gas available for distribution by its public service corporations, 77.1 per cent. was exported in the year 1916; 80.1 per cent. in 1917; 76.7 per cent. in 1918.  The West Virginia consumers complained that the amount furnished them was inadequate, and that they were being discriminated against by West Virginia gas companies, in the interest of residents of other states.  Some of the companies which exported gas sought to justify the ina equacy of their service to West Virginia customers by asserting that they were under contract, or other duty, to supply West Virginia gas to distributing companies or consumers in other states, and that the aggregate demand of their customers in the several states exceeded the available supply. Only 12 of the 67 West Virginia public service corporations took part in the export business. The remaining 55 were engaged solely in distribution within the state, and many of these were dependent largely upon the other 12 for their gas supply. Some of these 55 companies sought to justify their inadequate service by the fact that, because of the demands for gas to be exported to the other states, the corporations on which they were dependent denied them their full supply.

West Virginia consumers insisted that the common law forbade its public service companies to so disable themselves from performaning their duty to give adequate service within the state, and contended that the exporting public service corporations which habitually supplied the local distributing companies could not justify furnishing a reduced supply by setting up their contracts to furnish supplies to concerns in other states. These contentions were denied by the exporting companies, and it was asserted that they could not legally be controlled in this respect by the Public Service Commission of West Virginia. To remove all doubt concerning the statutory powers of the commission and to insure adequate service to West Virginia consumers, the Legislature of the state enacted chapter 71 of the Acts of 1919 approved on February 17 of that year, to take effect 90 days after its passage. That statute declared these rules of substantive law:

(a) That no public service corporation engaged in distributing natural gas produced within the state shall, by exporting its supply to other states, disable itself from performing its duty to give adequate service within West Virginia.

(b) That any such public service corporation whose gas supply is insufficient to afford such service to its customers may, under prescribed conditions, call upon any other public service corporation within the same territory, which has a surplus supply, to furnish to it such part of this surplus as may be required to enable it to give adequate service.

Before the effective date of that act, the state of Pennsylvania and the state of Ohio each filed in this court a bill in equity against the state of West Virginia, in which it prayed that the act be declared void, because obnoxious to the federal Constitution, and that all West Virginia officials be enjoined from attempting in any way to enforce the statute. As a basis for the relief each bill set forth the extensive use of natural gas by state institutions, by their several municipalities, and by millions of residents, and it alleged that serious injury would result if these consumers were deprived of the West Virginia supply. The Ohio bill alleged  lso that cutting off the West Virginia supply of natural gas would greatly reduce the value of public service properties, would reduce taxable values of these and other properties, and would thereby deprive the state of important revenues. It prayed, specifically, that the plaintiff state, and its residents, be declared to have no adequate remedy at law; that West Virginia and its officials be enjoined from interfering with the transportation of natural gas for use in Ohio; and that pending the suit an injunction be granted against their instituting in any court of the state of West Virginia and suit under the statute against any 'person, company or corporation which is engaged in the production or transportation of natural gas out of the state of West Virginia into the state of Ohio.' No public official or producer, exporter, or distributor of gas or consumer (other than these states) was made party plaintiff or defendant in either bill. A temporary injunction issued in each case upon the filing of the bill. In each a motion to dismiss, an answer, and a replication was filed. Without disposing of the motions to dismiss, the parties proceeded to take the evidence and, thereafter, submitted the cases for final hearing.

Several objections made to the maintenance of these suits may be passed without discussion. It will be assumed that the constitutional question submitted is not to be deemed merely a political one, as in Georgia v. Stanton, 6 Wall. 50, 18 L. Ed. 721, and Massachusetts v. Mellon, 262 U.S. 447, 43 Sup. Ct. 597, 67 L. Ed. --, decided June 4, 1923. It will be assumed that the alleged right to acquire by purchase and to bring into a state natural gas produced elsewhere is-despite a fundamental difference -to be treated as similar legally to the right asserted in Kansas v. Colorado, 185 U.S. 125, 22 Sup. Ct. 552, 46 L. Ed. 838; Id., 206 U.S. 46, 27 Sup. Ct. 655, 51 L. Ed. 956, to have the water of an interstate stream continue to flow into a state, or the right recognized in Missouri v. Illinois, 180 U.S. 208, 21 Sup. Ct. 331, 45 L. Ed. 497; New York v. New Jersey, 256 U.S. 296, 41 Sup. Ct. 492, 65 L. Ed. 937, and Georgia v. Tennessee Copper Co., 206 U.S. 230, 27 Sup. Ct. 618, 51 L. Ed. 1038, 11 Ann. Cas. 488, to have the waters and the air within one state kept reasonably free from pollution originating in another. It will be assumed, further, that the use of natural gas in Pennsylvania and in Ohio is shown to be so general as to bring these suits within the rule acted upon in the cases just cited and to render inapplicable the rule declared in Kansas v. United States, 204 U.S. 331, 27 Sup. Ct. 388, 51 L. Ed. 510, and Oklahoma v. Atchison, Topeka & Santa Fe Railway Co., 220 U.S. 277, 286, 289, 31 Sup. Ct. 434, 55 L. Ed. 465, where the suits were dismissed because brought in aid of interests deemed provate. And finally it will be assumed-although this is still more doubtful-that a state which has permitted one of its natural resources to be freely dealt in as an article of interstate commerce may not thereafter prohibit all export thereof, although it appears that the whole of the remaining supply will be required to satisfy the needs of its own citizens. These objections raised by defendant will not be considered, because there are other objections which, in my opinion, present insuperable obstacles to the maintenance of the suits.

First. This court is without jurisdiction of the subject-matter.

The bills present neither a 'case,' nor a 'controversy,' within the meaning of the federal Constitution. Marbury v. Madison, I Cranch, 137, 2 L. Ed. 60; Muskrat v. United States, 219 U.S. 346, 356, 359, 31 Sup. Ct. 250, 55 L. Ed. 246; Texas v. Interstate Commerce Commission, 258 U.S. 158, 42 Sup. Ct. 261, 66 L. Ed. 531. They are not proceedings 'instituted according to the regular course of judicial procedure' to protect some right of property or personal right. They are, like McChord v. Louisville & Nashville Railroad, 183 U.S. 483, 495, 22 Sup. Ct. 165, 46 L. Ed. 289, an attempt to enjoin, not executive action, but legislation. They are instituted frankly to secure from this court a general declaration that the West Virginia Act of February 17, 1919, is unconstitutional. Compare Giles v. Harris, 189 U.S. 475, 486, 23 Sup. Ct. 639, 47 L. Ed. 909. The wel-settled rule that the court is without power to entertain such a proceeding applies equally, whether the party invoking its aid is a state or a private person. And the rule cannot be overcome by giving to pleadings the form of a institutions, themselves consumers of West Fairchild v. Hughes, 258 U.S. 126, 42 Sup. Ct. 274, 66 L. Ed. 499; Atherton Mills v. Johnston, 259 U.S. 13, 15, 42 Sup. Ct. 422, 66 L. Ed. 814; Texas v. Interstate Commerce Commission, supra.

Moreover, it is not shown that there is, in a legal sense, danger of invasion of the alleged rights. It is shown that the states of Pennsylvania and Ohio are, in their public institutions, themselves consumers of West Virginia gas-a 'makeweight' as suggested in Georgia v. Tennessee Copper Co., 206 U.S. 230, 237, 27 Sup. Ct. 618, 51 L. Ed. 1038, 11 Ann. Cas. 488. And it is shown that these and many other consumers within the plaintiff states would suffer serious injury if the West Virginia supply were cut off. But it is primarily at least, because of acts or omissions is threatened or that there is, in a legal sense, danger that the supply will be stopped. The mere enactment of the statute, obviously, does not constitute a threat to interrupt the flow of gas into the plaintiff states. The importation into Ohio and Pennsylvania is conducted, not by the state of West Virginia, but wholly by 12 privately owned public service corporations. If the importation ceases it will be, irimarily at least, because of acts or omissions of these 12 corporations. Yet there is not even an allegation that these corporations threaten, or intend, to discontinue the importation, or that they will be compelled to do so unless the state of West Virginia is enjoined from enforcing the statute.

On the other hand, it clearly appears that, under the laws of West Virginia, there can be no present danger that any of these 12 corporations will be summarily prevented by that state from continuing in full volume the export of gas or will be compelled to reduce it. The only restriction, if any, imposed by the act of 1919 upon exportation of gas is that which may result from the requirement that West Virginia public service corporations shall not, by means of export, disable themselves from performing their duties to consumers and to other dis tributing companies within the state. Before there can be, in a legal sense, danger that restriction will result, it must appear that one or more of the 12 exporting companies is disabling itself by such exportation, or is about to do so, and also that some state official is about to take effective action to prevent the exportation. But under the legislation of West Virginia many things would have to happen and much time must elapse before any of the exporting corporations would be under any legal duty to discontinue or  essen their exports, and still more time before it could actually be prevented from exporting gas. For, under West Virginia legislation, no executive officer and no court has power or jurisdiction to declare, or to enforce performance of, such alleged duty of a public service corporation until primary resort has been had to the Public Service Commission and the application to it has been acted upon, either by granting or by denying relief. United Fuel Gas Co. v. Public Service Commission, 73 W. Va. 571, 80 S. E. 931; State v. Bluefield Water Works Co., 86 W. Va. 260, 103 S. E. 340; Kelly Axe Manufacturing Co. v. United Fuel Gas. Co., 87 W. Va. 368, 105 S. E. 152. The act establishing the commission prescribes the methods and the remedies which are to be pursued in order to enforce the duty to give adequate service. Chapter 9, Acts of 1913, §§ 11 and 18; chapter 8, Acts of 1915, §§ 23, 24; chapter 71, Acts of 1919; chapter 150, Acts of 1921; Manufacturers' Light & Heat Co. v. Ott (D. C.) 215 Fed. 940. If it is claimed that there is failure to give adequate service, a petition may be filed before the commission to secure it. After notice to and hearing of the corporation by the commission an order may be made. Until the commission issues some order which purports to restrict in some way the discretion theretofore exercised by a corporation in respect to exports, every such concern is, under the act of 1919, legally as free to continue the transportation of gas to Pennsylvania and to Ohio as if that statute had not been passed.

It is possible that the commission would never be called upon to act.  It is possible that, if called upon, the commission would refuse to make an order. It is possible that, if the commission made an order, the order would be of such a character as not to affect seriously the interests which plaintiff seeks to protect. And it is possible that if any order were made, the state court would suspend its operation and would eventually annul it. That act makes such careful provision for judicial review of the orders of the commission and for postponing the incidence of penalties or other liabilities until after such review can be had, that there could never be occasion for invoking in respect to this statute the doctrine of Ex parte Young, 209 U.S. 123, 28 Sup. Ct. 441, 52 L. Ed. 714, 13 L. R. A.(N.S.) 932, 14 Ann. Cas. 764.  For the commission is without power to enforce an order or to impose a penalty To overcome disobedience, or disregard, of an order, resort must, under the West Virginia statutes, be had to the courts, and to this end an original proceeding must be instituted. Whether the suit to enforce obedience is brought by the commission or by others, the corporation is given opportunity to defend on the ground that the order is, for any reason, invalid; or it may itself inaugurate the proceeding by bringing suit to have the order annulled. Randall Gas Co. v. Star Glass Co., 78 W. Va. 252, 256, 88 S. E. 840; United Fuel Gas Co. v. Public Service Commission, 73 W. Va. 571, 80 S. E. 931. Moreover, a final order of the commission is not enforceable, even by a court, until 30 days after entry have elapsed. That period is allowed within which any party feeling aggrieved may apply to the court for suspension of the order; and if such application is made, a speedy hearing must be given (section 16).

Up to the time when these suits were begun no action of any kind had been taken in relation to matters dealt with by the Act of February 17, 1919, either by the commission, by any other board or official of the state, by any corporation, or by any other person who could ever be affected by any provision of the statute. And no action could have been taken, for the act was then not yet in effect. How, then, can it be said that, in any legal sense, the Pennsylvania and Ohio consumers were in present danger of irreparable injury? Plaintiffs' fears were at best premature. This court held in Oregon v. Hitchcock, 202 U.S. 60, 70, 26 Sup. Ct. 568, 50 L. Ed. 935, that it would not, even at the instance of a state, take upon itself the decision of questions committed to another department of our government and thus anticipate the action of the federal executive. The reasons are equally strong against our interfering, in advance of decision, with the executive of a state  n a matter committed to its determination. If these were private suits relief would necessarily be denied. Compare First National Bank of Albuquerque v. Albright, 208 U.S. 548, 28 Sup. Ct. 349, 52 L. Ed. 614; South Carolina v. Georgia, 93 U.S. 4, 14, 23 L. Ed. 782. As the suit is that of one state against another, even greater caution should be exercised by this court before assuming to act. Missouri v. Illinois, 200 U.S. 496, 520, 521, 26 Sup. Ct. 268, 50 L. Ed. 572; Kansas v. Colorado, 206 U.S. 46, 117, 27 Sup. Ct. 655, 51 L. Ed. 956; New York v. New Jersey, 256 U.S. 296, 309, 41 Sup. Ct. 492, 65 L. Ed. 937. The objection here is not, as in Georgia v. Tennessee Copper Co., 206 U.S. 230, 238, 27 Sup. Ct. 618, 51 L. Ed. 1038, 11 Ann. Cas. 488, that those interested should be left to an action at law for redress of any injuries which may be suffered. It is that the 'judicial stage' of the controversy had not been reached when these suits were begun, and, indeed, has not been since. See Prentis v. Atlantic Coast Line Co., 211 U.S. 210, 228, 29 Sup. Ct. 67, 53 L. Ed. 150, 43 L. R. A. (N. S.) 1015; Bacon v. Rutland R. R. Co., 232 U.S. 134, 137, 34 Sup. Ct. 283, 58 L. Ed. 538.

Second. There is a fatal lack of necessary parties. It is only by failure of the 12 exporting companies to continue the exportation of gas that the plaintiffs, and other consumers or the distributing companies in Pennsylvania or Ohio, can be injured. Primarily at least, it is the rights of these 12 corporations, if of any one, which would be invaded by enforcing the statute, and rights of consumers and of distributing corporations of Pennsylvania and Of Ohio are derivative merely. Whether the West Virginia corporations may furnish gas to the plaintiff states and whether those corporations may be regulated as the statute attempts, are at most controversies between West Virginia and those corporations. They have not submitted their rights to adjudication in these suits. It is intimated that these corporations wish to have the act declared void. But we may not assume that such is their wish. Conceivably a decision holding the act valid might benefit them; since it might relieve them from improvident contracts with distributing companies in Pennsylvania and Ohio. Or it may be that some of the 12 corporations would be benefited and others injured by any decision made of the question presented. Unless the 12 corporations are legally represented either by the plaintiff or the defendant, they would not be bound by a decree in either of these suits. New Orleans Water Works Co. v. New Orleans, 164 U.S. 471, 480, 17 Sup. Ct. 161, 41 L. Ed. 518. That neither plaintiff nor defendant legally represents them is clear.  And since they would not be found, this court should not entertain a suit to decide the question presented; for, as was held in California v. Southern Pacific Co., 157 U.S. 229, 15 Sup. Ct. 591, 39 L. Ed. 683, and Minnesota v. Northern Securities Co., 184 U.S. 199, 246, 22 Sup. Ct. 308, 46 L. Ed. 499, it does not comport with the gravity and finality which should characterize an adjudication in the exercise of the original jurisdiction of this court to proceed, at the instance of a state, in the absence of parties whose rights would be actually passed upon and be in effect determined, even though they might not be technically bound in subsequent litigation in this, or some other tribunal. Compare Texas v. Interstate Commerce Commission, 258 U.S. 158, 42 Sup. Ct. 261, 66 L. Ed. 531.

The remaining 55 West Virginia gas corporations which do not expo t any gas are also vitally interested in the question submitted. So far as their interest is the general one qua consumer, it might be represented by the Public Service Commission, and to that end the commission (not the state) should, perhaps, have been made party defendant. But many of these gas corporations appear to have specific interests which a decision might affect directly. They have contracts with the exporting companies for their supply of gas; and the obligations under these contracts would be different if the act is held valid than if it were held to be void. A decision to the effect that the prohibition of exports declared in the act is void might seriously impair their contract rights.

'That the sections, provisions and clauses of this act shall      be deemed separable each from the other, and also in respect      to the persons, firms, corporations and consumers mentioned      therein or affected thereby, and if any separable part of      this act be, or be held to be unconstitutional or for any      reason invalid or unenforceable, the remaining parts thereof      shall be and remain in full force and effect.'

Surely the statute may be valid as to some exporting companies, for the action in exporting may be ultra vires; or certain West Virginia distributing companies may have acquired preferential rights to the supply of gas. How can the court determine, in view of this provision, that the act is void, in toto, when it has not before it the parties to be affected thereby and the facts which only they as litigants would be able to present? Therefore, even if it appeared that rights of the plaintiffs-or of those whom they legally represent-were in present danger of irreparable injury resulting from wrongful acts of defendant, these suits should not be maintained.

Third. But if all other obstacles could be overcome, this court, sitting as a court of equity, should dismiss the bills, because it would be unable to grant the only relief appropriate. This court, sitting in equity, clearly should not lend its aid to enable West Virgina public service corporations to discriminate against West Virginia consumers in the interest of Ohio and Pennsylvania consumers. Therefore an appropriate decree should be framed so as to require each of the West Virginia corporations to treat West Virginia customers at least as well as it does those outside of the state and the decree should not leave any West Virginia public service corporation free to export gas in disregard of the duty not to discriminate against the public of that state. But natural gas is produced also in Pennsylvania and Ohio, and equitably with other states now dependent the supplies cansumed in those states.  Furthermore, West Virginia gas is exported also to Maryland, Indiana, and Kentucky and in two of those states natural gas is produced in quantity.  Clearly the court should, in no event, go further than to compel West Virginia to share its production equitable with other state now dependent upon it for a part of their gas supply. But in order to determine what is equitable (that is, what part of the West Virginia production that state might require its public service corporations to retain and what part they should be free to export to other states) it would obviously be necessary to marshall the resources and the demands, or needs, of the six states, and to consider, in respect to each, both the conduct of the business therein and the circumstances attending its development. The factors necessary to be considered in determining what division of the West Virginia production would be fair, the conditions under which the determination would have to be made, and the character of the questions to be decided are such that this court would be obliged to refuse to undertake the task. For this reason, the bills should be dismissed, even if it were held both that rights legally represented by plaintiffs were in present danger of irreparable injury by wrongful acts of defendant an  that there was not a fatal lack of necessary parties. To do justice as between the several states the following inquiries would be essential:

(a) The potential as well as the actual production in each state would have to be ascertained. The actual production during earlier years, and approximately the current production, could be ascertained from data which are regularly collected by the United States Geological. Survey and by the public utility commissions of the several states. But to ascertain the potential production, searching inquiry would have to be made into the methods of production pursued, and, among other things, to what extent recent production has been secured by forcing the wells, what the likelihood is that production lessened by forcing wells will be restored by allowing periods of rest, and to what extent recent reduced outputs may have been atributable to failure to sink enough wells or to open additional territory.  It would be necessary to inquire also into the extent and character of the existing gas reserves, where-ever situated and by whomsoever owned. In ascertaining the extent of the gas territory not yet developed, it would be necessary to inquire to what extent the reserve is controlled by, or is otherwise available to, the several public service corporations of the several states; the cost of developing particular fields and of marketing the supply therefrom; what the relation of such undeveloped territory is to that then being worked and to that already exhausted; and to what extent and how rapidly the development of new areas and new sources of supply should properly proceed.

(b) The demand, actual and potential, in each state would have to be determined. In determining the demand, the court could not confine its inquiry to ascer taining the amount then used or called for. The rates charged in the several communities must also be considered. For upon these, as well as upon the relative cost of other kinds of fuel, would depend in large part the extent of the demand, particularly by the industries. The character of the use and the circumstances under which it had been developed would likewise be important factors in deciding what distribution would be equitable. Among other things, it would be necessary to determine to what extent there was, as in Ohio, a high percentage of waste, and what investment had been made in distributing mains and in customers' appliances and when and under what circumstances these investments had been made. For, while a long-established local distributing company might reasonably be required to restrict its business to existing customers and even to the existing needs of such, a like restriction would be a great hardship, if applied to new companies which had not yet brought their business to a paying basis.

(c) No determination concerning production and none concerning demand could afford a stable basis for future action; for no factor entering into the determination would be constant. Investigations into supply and demand would have to be pursued continuously, and recurrent decisions as to distribution would be required. Thus, the estimate of the undeveloped gas territory must be ever changing; for new discovery may open territory theretogore unknown, and the sinking of test wells may establish the  act that territory previously deemed valuable will be wholly unproductive. In no other field of public service regulation is the controlling body confronted with factors so baffling as in the natural gas industry, and in none is continuous supervision and control required in so high a degree.

(d) The decisions to be made would be of the character which calls for the informed judgment of a board of experts. The tribunal would have to determine, among other things, whether inadequate service was due in the several states to inadequate supply or to improvident use by some consumers; whether to overcome inadequacy of supply new territory should be developed or more wells be sunk in old territory; whether, in view of prospective needs of the several communities, it would not be better that the reserves should be husbanded and that the uses to which gas may be put be curtailed. It would thus be called upon to review-and perhaps to control-the business judgment of those managing the companies. Pro rata distribution among all users of the gas from time to time available would obviously not result in equitable distribution; for domestic users, and also many industrial ones, would, if their gas supply were uncertain, find it necessary to assure themselves of an adequate supply for heating, cooking, and power, of either oil or some other kind of fuel, and the expense of producing the necessary alternative appliances would be large. The tribunal would have to decide, also, many other serious questions of the character usually committed for determination to public utility commissions, and the difficulties involved in these decisions would be much enhanced by differences in the laws, rules and practices of the several states regarding the duties of natural gas companies to furnish adequate service. 

Cearly this court not undertake such determinations. equitable distribution would be a task of such complexity and difficulty that even an interstate public service commission, with broad powers, perfected administrative machinery, ample resources, practical experience, and no other duties, might fail to perform it satisfactorily. As this court would be powerless to frame a decree and provide machinery by means of which such equitable distribution of the available supply could be effected, it should, according to settled practice, refuse to entertain the suits. Compare Marble Co. v. Ripley, 10 Wall. 339, 358, 19 L. Ed. 955; Taxas & Pacific Railway Co. v. Marshall, 136 U.S. 393, 406, 10 Sup. Ct. 846, 34 L. Ed. 385; Giles v. Harris, 189 U.S. 475, 487, 488, 23 Sup. Ct. 639, 47 L. Ed. 909.

PER CURIAM.

These suits havi g been heretofore submitted on the pleadings and the evidence, and the court being now fully advised in the premises,

It is considered, ordered and decreed as follows:

1. That the act passed by the Legislature of the defendant state February 10, 1919, which is set forth in the bills of complaint in these suits and known as chapter 71 of the West Virginia Acts of 1919, is a void and inoperative enactment, because it contravenes the limitations which the Constitution of the United States places upon state action in respect of commerce among the several states.

2. That the defendant state, and her several officers, agents and servants, are hereby severally enjoined from enforcing, or atttempting to enforce, that act.

3. That the aggregate costs in these suits be apportioned among and paid by the parties thereto as follows: The state of West Virginia one-half; the commonwealth of Pennsylvania one-fourth and the state of Ohio one-fourth.

4. That Levi Cooke, Esq., the commissioner by whom the evidence in these suits was taken and reported to this court, shall receive and be paid the sum of $6,000 in full compensation for the services rendered and the expenses incurred by him in that connection, and that this sum be taxed as part of the aggregate costs in the two suits and be paid by the parties in the proportions just named.

5. That the clerk of this court transmit to the Chief Magistrates of the commonwealth of Pennsylvania and the states of Ohio and West Virginia copies of this decree, duly authenticated under the seal of this court.
