Gouled v. United States
Gouled v. United States (1921) – simple summary
Gouled v. United States was a Supreme Court case about how police collect evidence. The Court ruled that the government cannot seize evidence by stealth, trickery, or social manipulation. Doing so can violate the Fourth Amendment (protection against unreasonable searches and seizures) and the Fifth Amendment (protection against self-incrimination). The Court also said that evidence taken this way should be excluded at trial unless there is another lawful reason for it to be admitted.
Before the case, Boyd v. United States had laid groundwork about how the government can get evidence. Gouled expanded on that idea and created what is often called the “mere evidence rule” — the government cannot seize property that is useful only as evidence, unless the item is contraband, stolen, or a tool of the crime.
In this case, Felix Gouled and others were accused of trying to defraud the United States. A friend of Gouled, Cohen, came to Gouled’s office under a friendly pretense, stayed when Gouled was alone, and searched for and removed papers without a warrant. The papers were used at Gouled’s trial, and he was convicted.
The Supreme Court answered six questions from the lower court about the Fourth and Fifth Amendments, unanimously agreeing that seizing evidence through social trickery or stealth violates those amendments. The Court held that such evidence must be excluded at trial unless there is another lawful way to admit it. While the rule was clear and straightforward, applying it in real life situations could be tricky, especially as the Constitution’s protections were extended to the states.
Because of these difficulties in later cases, the exact rule from Gouled was rejected in 1967 in Warden v. Hayden.
