Words truer now than when they were written: The prescient Brandeis dissent in Olmstead v. United States.

Olmstead v. United States, 277 U.S. 438 (1928), was a decision of the Supreme Court of the United States, in which the Court reviewed whether the use of wiretapped private telephone conversations, obtained by federal agents without judicial approval and subsequently used as evidence, constituted a violation of the defendant’s rights provided by the Fourth and Fifth Amendments. In a 5-4 decision, the Court held that neither the Fourth Amendment nor the Fifth Amendment rights of the defendant were violated. This decision was overturned by Katz v. United States in 1967. -- Wikipedia.

"Experience should teach us to be most on our guard to protect liberty when the government's purposes are beneficent. Men born to freedom are naturally alert to repel invasion of their liberty by evil-minded rulers. The greatest dangers to liberty lurk in insidious encroachment by men of zeal, well-meaning but without understanding."

The entire dissent by Justice Brandeis:

The defendants were convicted of conspiring to violate the National Prohibition Act (27 USCA). Before any of the persons now charged had been arrested or indicted, the telephones by means of which they habitually communicated with one another and with others had been tapped by federal officers. To this end, a lineman of long experience in wire tapping was employed, on behalf of the government and at its expense. He tapped eight telephones, some in the homes of the persons charged, some in their offices. Acting on behalf of the government and in their official capacity, at least six other prohibition agents listened over the tapped wires and reported the messages taken. Their operations extended over a period of nearly five months. The typewritten record of the notes of conversations overheard occupies 775 typewritten pages. By objections seasonably made and persistently renewed, the defendants objected to the admission of the evidence obtained by wire tapping, on the ground that the government's wire tapping constituted an unreasonable search and seizure, in violation of the Fourth Amendment, and that the use as evidence of the conversations overheard compelled the defendants to be witnesses against themselves, in violation of the Fifth Amendment.

The government makes no attempt to defend the methods employed by its officers. Indeed, it concedes that, if wire tapping can be deemed a search and seizure within the Fourth Amendment, such wire tapping as was practiced in the case at bar was an unreasonable search and seizure, and that the evidence thus obtained was inadmissible. But it relies on the language of the amendment, and it claims that the protection given thereby cannot properly be held to include a telephone conversation.

'We must never forget,' said Mr. Chief Justice Marshall in McCulloch v. Maryland, 4 Wheat. 316, 407 4 L. Ed. 579, 'that it is a Constitution we are expounding.' Since then this court has repeatedly sustained the exercise of power by Congress, under various clauses of that instrument, over objects of which the fathers could not have dreamed. See Pensacola Telegraph Co. v. Western Union Telegraph Co., 96 U.S. 1 , 9; Northern Pacific Ry. Co. v. North Dakota, 250 U.S. 135 , 39 S. Ct. 502; Dakota Central Telephone Co. v. South Dakota, 250 U.S. 163 , 39 S. Ct. 507, 4 A. L. R. 1623; Brooks v. United States, 267 U.S. 432 , 45 S. Ct. 345, 37 A. L. R. 1407. We have likewise held that general limitations on the powers of government, like those embodied in the due process clauses of the Fifth and Fourteenth Amendments, do not forbid the United States or the states from meeting modern conditions by regulations which 'a century ago, or even half a century ago, probably would have been rejected as arbitrary and oppressive.' Village of Euclid v. Ambler Realty Co., 272 U.S. 365, 387 , 47 S. Ct. 114, 118 (71 L. Ed. 303); Buck v. Bell, 274 U.S. 200 , 47 S. Ct. 584, 71 L. 1000. Clauses guaranteeing to the individual protection against specific abuses of power, must have a similar capacity of adaptation to a changing world. It was with reference to such a clause that this court said in Weems v. United States, 217 U.S. 349, 373 , 30 S. Ct. 544, 551 (54 L. Ed. 793, 19 Ann. Cas. 705):

'Legislation, both statutory and constitutional, is enacted, it is true, from an experience of evils, but its general language should not, therefore, be necessarily confined to the form that evil had theretofore taken. Time works changes, brings into existence new conditions and purposes. Therefore a principal to be vital must be capable of wider application than the mischief which gave it birth. This is peculiarly true of Constitutions. They are not ephemeral enactments, designed to meet passing occasions. They are, to use the words of Chief Justice Marshall, 'designed to approach immortality as nearly as human institutions can approach it.' The future is their care and provision for events of good and bad tendencies of which no prophecy can be made. In the application of a Constitution, therefore, our contemplation cannot be only of what has been but of what may be. Under any other rule a Constitution would indeed be as easy of application as it would be deficient in efficacy and power. Its general principles would have little value and be converted by precedent into impotent and lifeless formulas. Rights declared in words might be lost in reality.'

When the Fourth and Fifth Amendments were adopted, 'the form that evil had theretofore taken' had been necessarily simple. Force and violence were then the only means known to man by which a government could directly effect self-incrimination. It could compel the individual to testify-a compulsion effected, if need be, by torture. It could secure possession of his papers and other articles incident to his private life-a seizure effected, if need be, by breaking and entry. Protection against such invasion of 'the sanctities of a man's home and the privacies of life' was provided in the Fourth and Fifth Amendments by specific language. Boyd v. United States, 116 U.S. 616, 630 , 6 S. Ct. 524. But 'time works changes, brings into existence new conditions and purposes.' Subtler and more far-reaching means of invading privacy have become available to the government. Discovery and invention have made it possible for the government, by means far more effective than stretching upon the rack, to obtain disclosure in court of what is whispered in the closet. Moreover, 'in the application of a Constitution, our contemplation cannot be only of what has been, but of what may be.' The progress of science in furnishing the government with means of espionage is not likely to stop with wire tapping. Ways may some day be developed by which the government, without removing papers from secret drawers, can reproduce them in court, and by which it will be enabled to expose to a jury the most intimate occurrences of the home. Advances in the psychic and related sciences may bring means of exploring unexpressed beliefs, thoughts and emotions. 'That places the liberty of every man in the hands of every petty officer' was said by James Otis of much lesser intrusions than these. To Lord Camden a far slighter intrusion seemed 'subversive of all the comforts of society.' Can it be that the Constitution affords no protection against such invasions of individual security?

A sufficient answer is found in Boyd v. United States, 116 U.S. 616 , 627-630, 6 S. Ct. 524, a case that will be remembered as long as civil liberty lives in the United States. This court there reviewed the history that lay behind the Fourth and Fifth Amendments. We said with reference to Lord Camden's judgment in Entick v. Carrington, 19 Howell's State Trials, 1030:

'The principles laid down in this opinion affect the very essence of constitutional liberty and security. They reach farther than the concrete form of the case there before the court, with its adventitious circumstances; they apply to all invasions on the part of the government and its employe of the sanctities of a man's home and the privacies of life. It is not the breaking of his doors, and the rummaging of his drawers, that constitutes the essence of the offense; but it is the invasion of his indefeasible right of personal security, personal liberty and private property, where that right has never been forfeited by his conviction of some public offense-it is the invasion of this sacred right which underlies and constitutes the essence of Lord Camden's judgment. Breaking into a house and opening boxes and drawers are circumstances of aggravation; but any forcible and compulsory extortion of a man's own testimony or of his private papers to be used as evidence of a crime or to forfeit his goods, is within the condemnation of that judgment. In this regard the Fourth and Fifth Amendments run almost into each other.'

In Ex parte Jackson, 96 U.S. 727 , it was held that a sealed letter intrusted to the mail is protected by the amendments. The mail is a public service furnished by the government. The telephone is a public service furnished by its authority. There is, in essence, no difference between the sealed letter and the private telephone message. As Judge Rudkin said below:

'True, the one is visible, the other invisible; the one is tangible, the other intangible; the one is sealed, and the other unsealed; but these are distinctions without a difference.'

The evil incident to invasion of the privacy of the telephone is far greater than that involved in tampering with the mails. Whenever a telephone line is tapped, the privacy of the persons at both ends of the line is invaded, and all conversations between them upon any subject, and although proper, confidential, and privileged, may be overheard. Moreover, the tapping of one man's telephone line involves the tapping of the telephone of every other person whom he may call, or who may call him. As a means of espionage, writs of assistance and general warrants are but puny instruments of tyranny and oppression when compared with wire tapping.

Time and again this court, in giving effect to the principle underlying the Fourth Amendment, has refused to place an unduly literal construction upon it. This was notably illustrated in the Boyd Case itself. Taking language in its ordinary meaning, there is no 'search' or 'seizure' when a defendant is required to produce a document in the orderly process of a court's procedure. 'The right of the people of be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures,' would not be violated, under any ordinary construction of language, by compelling obedience to a subpoena. But this court holds the evidence inadmissible simply because the information leading to the issue of the subpoena has been unlawfully secured. Silverthorne Lumber Co. v. United States, 251 U.S. 385 , 40 S. Ct. 182. Literally, there is no 'search' or 'seizure' when a friendly visitor abstracts papers from an office; yet we held in Gouled v. United States, 255 U.S. 298 , 41 S. Ct. 261, that evidence so obtained could not be used. No court which looked at the words of the amendment rather than at its underlying purpose would hold, as this court did in Ex parte Jackson, 96 U.S. 727 , 733, that its protection extended to letters in the mails. The provision against self-incrimination in the Fifth Amendment has been given an equally broad construction. The language is:

'No person ... shall be compelled in any criminal case to be a witness against himself.'

Yet we have held not only that the protection of the amendment extends to a witness before a grand jury, although he has not been charged with crime (Counselman v. Hitchcock, 142 U.S. 547, 562 , 586 S., 12 S. Ct. 195), but that:

'It applies alike to civil and criminal proceedings, wherever the answer might tend to subject to criminal responsibility him who gives it. The privilege protects a mere witness as fully as it does one who is also a party defendant.' McCarthy v. Arndstein, 266 U.S. 34, 40 , 45 S. Ct. 16, 17 (69 L. Ed. 158).

The narrow language of the Amendment has been consistently construed in the light of its object, 'to insure that a person should not be compelled, when acting as a witness in any investigation, to give testimony which might tend to show that he himself had committed a crime. The privilege is limited to criminal matters, but it is as broad as the mischief against which it seeks to guard.' Counselman v. Hitchcock, supra, page 562 (12 S. Ct. 198).

Decisions of this court applying the principle of the Boyd Case have settled these things. Unjustified search and seizure violates the Fourth Amendment, whatever the character of the paper; whether the paper when taken by the federal officers was in the home, in an office, or elsewhere; whether the taking was effected by force, by fraud, or in the orderly process of a court's procedure. From these decisions, it follows necessarily that the amendment is violated by the officer's reading the paper without a physical seizure, without his even touching it, and that use, in any criminal proceeding, of the contents of the paper so examined-as where they are testified to by a federal officer who thus saw the document or where, through knowledge so obtained, a copy has been procured elsewhere11-any such use constitutes a violation of the Fifth Amendment.

The protection guaranteed by the amendments is much broader in scope. The makers of our Constitution undertook to secure conditions favorable to the pursuit of happiness. They recognized the significance of man's spiritual nature, of his feelings and of his intellect. They knew that only a part of the pain, pleasure and satisfactions of life are to be found in material things. They sought to protect Americans in their beliefs, their thoughts, their emotions and their sensations. They conferred, as against the government, the right to be let alone-the most comprehensive of rights and the right most valued by civilized men. To protect, that right, every unjustifiable intrusion by the government upon the privacy of the individual, whatever the means employed, must be deemed a violation of the Fourth Amendment. And the use, as evidence in a criminal proceeding, of facts ascertained by such intrusion must be deemed a violation of the Fifth.

Applying to the Fourth and Fifth Amendments the established rule of construction, the defendants' objections to the evidence obtained by wire tapping must, in my opinion, be sustained. It is, of course, immaterial where the physical connection with the telephone wires leading into the defendants' premises was made. And it is also immaterial that the intrusion was in aid of law enforcement. Experience should teach us to be most on our guard to protect liberty when the government's purposes are beneficent. Men born to freedom are naturally alert to repel invasion of their liberty by evil-minded rulers. The greatest dangers to liberty lurk in insidious encroachment by men of zeal, well-meaning but without understanding.

Independently of the constitutional question, I am of opinion that the judgment should be reversed. By the laws of Washington, wire tapping is a crime. 13 Pierce's Code 1921, 8976(18). To prove its case, the government was obliged to lay bare the crimes committed by its officers on its behalf. A federal court should not permit such a prosecution to continue. Compare Harkin v. Brundage (No. 117) 276 U.S. 36 , 48 S. Ct. 268, decided February 20, 1928

[277 U.S. 438, 481] The situation in the case at bar differs widely from that presented in Burdeau v. McDowell, 256 U.S. 465 , 41 S. Ct. 574, 13 A. L. R. 1159. There only a single lot of papers was involved. They had been obtained by a private detective while acting on behalf of a private party, without the knowledge of any federal official, long before any one had thought of instituting a federal prosecution. Here the evidence obtained by crime was obtained at the government's expense, by its officers, while acting on its behalf; the officers who committed these crimes are the same officers who were charged with the enforcement of the Prohibition Act; the crimes of these officers were committed for the purpose of securing evidence with which to obtain an indictment and to secure a conviction. The evidence so obtained constitutes the warp and woof of the government's case. The aggregate of the government evidence occupies 306 pages of the printed record. More than 210 of them are filled by recitals of the details of the wire tapping and of facts ascertained thereby. There is literally no other evidence of guilt on the part of some of the defendants except that illegally obtained by these officers. As to nearly all the defendants (except those who admitted guilt), the evidence relied upon to secure a conviction consisted mainly of that which these officers had so obtained by violating the state law.

As Judge Rudkin said below (19 F.(2d) 842):

'Here we are concerned with neither eavesdroppers nor thieves. Nor are we concerned with the acts of private individuals. ... We are concerned only with the acts of federal agents, whose powers are limited and controlled by the Constitution of the United States.'

The Eighteenth Amendment has not in terms empowered Congress to authorize any one to violate the criminal laws of a state. And Congress has never purported to do so. Compare Maryland v. Soper, 270 U.S. 9 , 46 S. Ct. 185. The terms of appointment of federal prohibition agents do not purport to confer upon them authority to violate any criminal law. Their superior officer, the Secretary of the Treasury, has not instructed them to commit crime on behalf of the United States. It may be assumed that the Attorney General of the United States did not give any such instruction.

When these unlawful acts were committed they were crimes only of the officers individually. The government was innocent, in legal contemplation; for no federal official is authorized to commit a crime on its behalf. When the government, having full knowledge, sought, through the Department of Justice, to avail itself of the fruits of these acts in order to accomplish its own ends, it assumed moral responsibility for the officers' crimes. Compare the Paquete Habana, 189 U.S. 453, 465 , 23 S. Ct. 593; O'Reilly de Camara v. Brooke, 209 U.S. 45, 52 , 28 S. Ct. 439; Dodge v. United States, 272 U.S. 530, 532 , 47 S. Ct. 191; Gambino v. United States, 275 U.S. 310 , 48 S. Ct. 137, and if this court should permit the government, by means of its officers' crimes, to effect its purpose of punishing the defendants, there would seem to be present all the elements of a ratification. If so, the government itself would become a lawbreaker.

Will this court, by sustaining the judgment below, sanction such conduct on the part of the executive? The governing principle has long been settled. It is that a court will not redress a wrong when he who invokes its aid has unclean hands. 16 The maxim of unclean hands comes from courts of equity. But the principle prevails also in courts of law. Its common application is in civil actions between private parties. Where the government is the actor, the reasons for applying it are even more persuasive. Where the remedies invoked are those of the criminal law, the reasons are compelling.

The door of a court is not barred because the plaintiff has committed a crime. The confirmed criminal is as much entitled to redress as his most virtuous fellow citizen; no record of crime, however long, makes one an outlaw. The court's aid is denied only when he who seeks it has violated the law in connection with the very transaction as to which he seeks legal redress. Then aid is denied despite the defendant's wrong. It is denied in order to maintain respect for law; in order to promote confidence in the administration of justice; in order to preserve the judicial process from contamination. The rule is one, not of action, but of inaction. It is sometimes spoken of as a rule of substantive law. But it extends to matters of procedure as well. A defense may be waived. It is waived when not pleaded. But the objection that the plaintiff comes with unclean hands will be taken by the court itself. It will be taken despite the wish to the contrary of all the parties to the litigation. The court protects itself.

Decency, security, and liberty alike demand that government officials shall be subjected to the same rules of conduct that are commands to the citizen. In a government of laws, existence of the government will be imperiled if it fails to observe the law scrupulously. Our government is the potent, the omnipresent teacher. For good or for ill, it teaches the whole people by its example. Crime is contagious. If the government becomes a lawbreaker, it breeds contempt for law; it invites every man to become a law unto himself; it invites anarchy. To declare that in the administration of the criminal law the end justifies the means-to declare that the government may commit crimes in order to secure the conviction of a private criminal-would bring terrible retribution. Against that pernicious doctrine this court should resolutely set its face.
