A statute authorizes a specified federal administrative agency to issue rules governing the distribution of federal grant funds for scientific research. The statute provides that, in issuing those rules, the agency must follow procedures and substantive standards contained in the statute. In a severable provision, the statute also provides that otherwise valid rules issued by the agency under authority delegated to it by this statute may be set aside by a majority vote of a designated standing joint committee of Congress. The provision of this statute relating to the power of the designated standing joint committee of Congress is
constitutional, because it is a necessary and proper means of ensuring that the rules issued by this agency are actually consistent with the will of Congress.  constitutional, because discretionary money grants authorized by statute are privileges, not rights, and therefore Congress has greater freedom to intervene in their administration than it has to intervene in the administration of regulatory laws.  unconstitutional, because it denies equal protection of the laws to members of Congress who are not appointed to the joint legislative committee authorized to set aside rules of this agency.  unconstitutional, because it authorizes a congressional change of legal rights and obligations by means other than those specified in the Constitution for the enactment of laws.
