Seventy-five years ago, in Boyd v. United States, 116 U.S. 616, 630 (1886), considering the Fourth[fn4] and Fifth Amendments as running "almost into each other"[fn5] on the facts before it, this Court held that the doctrines of those Amendments
"apply to all invasions on the part of the government and its employes of the sanctity 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 offence; but it is the invasion of his indefeasible right of personal security, personal liberty and private property . . . . 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 to convict him of crime or to forfeit his goods, is within the condemnation . . . [of those Amendments]."
The Court noted that
"constitutional provisions for the security of person and property should be liberally construed. . . . It is the duty of courts to be watchful for the constitutional rights of the citizen, and against any stealthy encroachments thereon." At p. 635.
In this jealous regard for maintaining the integrity of individual rights, the Court gave life to Madison's prediction that "independent tribunals of justice . . . will be naturally led to resist every encroachment upon rights expressly stipulated for in the Constitution by the declaration of rights." I Annals of Cong. 439 (1789). Concluding, the Court specifically referred to the use of the evidence there seized as "unconstitutional." At p. 638.
Less than 30 years after Boyd, this Court, in Weeks v. United States, 232 U.S. 383 (1914), stated that
"the Fourth Amendment . . . put the courts of the United States and Federal officials, in the exercise of their power and authority, under limitations and restraints [and] . . . forever secure[d] the people, their persons, houses, papers and effects against all unreasonable searches and seizures under the guise of law . . . and the duty of giving to it force and effect is obligatory upon all entrusted under our Federal system with the enforcement of the laws." At pp. 391-392.
Specifically dealing with the use of the evidence unconstitutionally seized, the Court concluded:
"If letters and private documents can thus be seized and held and used in evidence against a citizen accused of an offense, the protection of the Fourth Amendment declaring his right to be secure against such searches and seizures is of no value, and, so far as those thus placed are concerned, might as well be stricken from the Constitution. The efforts of the courts and their officials to bring the guilty to punishment, praiseworthy as they are, are not to be aided by the sacrifice of those great principles established by years of endeavor and suffering which have resulted in their embodiment in the fundamental law of the land." At p. 393.
Finally, the Court in that case clearly stated that use of the seized evidence involved "a denial of the constitutional rights of the accused." At p. 398. Thus, in the year 1914, in the Weeks case, this Court "for the first time" held that "in a federal prosecution the Fourth Amendment barred the use of evidence secured through an illegal search and seizure." Wolf v. Colorado, supra, at 28. This Court has ever since required of federal law officers a strict adherence to that command which this Court has held to be a clear, specific, and constitutionally required — even if judicially implied — deterrent safeguard without insistence upon which the Fourth Amendment would have been reduced to "a form of words." Holmes, J., Silverthorne Lumber Co. v. United States, 251 U.S. 385, 392 (1920). It meant, quite simply, that "conviction by means of unlawful seizures and enforced confessions . . . should find no sanction in the judgments of the courts . . . ," Weeks v. United States, supra, at 392, and that such evidence "shall not be used at all." Silverthorne Lumber Co. v. United States, supra, at 392.
There are in the cases of this Court some passing references to the Weeks rule as being one of evidence. But the plain and unequivocal language of Weeks — and its later paraphrase in Wolf — to the effect that the Weeks rule is of constitutional origin, remains entirely undisturbed. In Byars v. United States, 273 U.S. 28 (1927), a unanimous Court declared that "the doctrine [cannot] . . . be tolerated under our constitutional system, that evidences of crime discovered by a federal officer in making a search without lawful warrant may be used against the victim of the unlawful search where a timely challenge has been interposed." At pp. 29-30 (emphasis added). The Court, in Olmstead v. United States, 277 U.S. 438 (1928), in unmistakable language restated the Weeks rule:
"The striking outcome of the Weeks case and those which followed it was the sweeping declaration that the Fourth Amendment, although not referring to or limiting the use of evidence in courts, really forbade its introduction if obtained by government officers through a violation of the Amendment." At p. 462.
In McNabb v. United States, 318 U.S. 332 (1943), we note this statement:
"[A] conviction in the federal courts, the foundation of which is evidence obtained in disregard of liberties deemed fundamental by the Constitution, cannot stand. Boyd v. United States . . . Weeks v. United States . . . . And this Court has, on Constitutional grounds, set aside convictions, both in the federal and state courts, which were based upon confessions 'secured by protracted and repeated questioning of ignorant and untutored persons, in whose minds the power of officers was greatly magnified' . . . or 'who have been unlawfully held incommunicado without advice of friends or counsel' . . . ." At pp. 339-340.
Significantly, in McNabb, the Court did then pass on to formulate a rule of evidence, saying, "in the view we take of the case, however, it becomes unnecessary to reach the Constitutional issue [for] . . . the principles governing the admissibility of evidence in federal criminal trials have not been restricted . . . to those derived solely from the Constitution." At pp. 340-341.
