Answer:

The phrase “fruit of the poisonous tree” is a legal term in the United States that refers to evidence obtained through illegal means. The idea is that if the source of the evidence (the “tree”) is tainted, then anything derived from it (the “fruit”) is also tainted. Such evidence is generally not admissible in court.

For example, if a police officer searches a home in violation of the Fourth Amendment and finds a key to a locker containing evidence of a crime, that evidence would likely be excluded under the fruit of the poisonous tree doctrine. This doctrine extends the exclusionary rule, which prevents evidence obtained in violation of the Fourth Amendment from being used in a criminal trial, with some exceptions. Both the exclusionary rule and this doctrine aim to deter law enforcement from using illegal methods to gather evidence.

A well-known example is the case of Wong Sun v. United States, 371 U.S. 471 (1963). In this case, evidence obtained through an illegal arrest was deemed inadmissible in court. The Supreme Court ruled that since the original arrest was unlawful, any evidence derived from it, such as a confession and drugs found later, was also inadmissible under the fruit of the poisonous tree doctrine.
