Burdeau v. McDowell/Dissent Brandeis
Mr. Justice BRANDEIS dissenting with whom Mr. Justice HOLMES concurs.

Plaintiff's private papers were stolen. The thief, to further his own ends, delivered them to the law officer of the United States. He, knowing them to have been stolen, retains them for use against the plaintiff. Should the court permit him to do so? That the court would restore the papers to plaintiff if they were still in the thief's possession is not questioned. That it has power to control the disposition of these stolen papers, although they have passed into the possession of the law officer, is also not questioned. But it is said that no provision of the Constitution requires their surrender and that the papers could have been subpoenaed. This may be true. Still I cannot believe that action of a public official is necessarily lawful, because it does not violate constitutional prohibitions and because the same result might have been attained by other and proper means. At the foundation of our civil liberty lies the principle which denies to government officials an exceptional position before the law and which subjects them to the same rules of conduct that are commands to the citizen. And in the development of our liberty insistence upon procedural regularity has been large factor. Respect for law will not be advanced by resort, in its enforcement, to means which shock the common man's sense of decency and fair play.
