The poisonous-tree doctrine, also known as the fruits doctrine, is a principle in criminal law that prohibits the use of evidence obtained from an illegal search, arrest, or interrogation in court. This is because the evidence is seen as tainted by the illegality, similar to a fruit from a poisonous tree. For instance, if the police discovered a murder weapon using a map seized during an illegal search, the weapon would not be admissible in court. The purpose of this rule is to safeguard individuals’ rights from unlawful actions by law enforcement.
The poisonous-tree doctrine is a principle in criminal procedure that declares evidence acquired from an unlawful search, arrest, or interrogation cannot be used in court. This is due to the fact that the evidence is considered tainted by the illegality, similar to a fruit from a poisonous tree. For instance, if the police unlawfully search a suspect’s residence and discover a murder weapon, the weapon cannot be presented as evidence in court. Even if the police later obtain a search warrant for the residence, the evidence remains inadmissible because it was obtained from an illegal search. This doctrine is crucial as it safeguards individuals’ rights and ensures that law enforcement adheres to proper procedures when collecting evidence. Additionally, it serves to prevent police misconduct and the abuse of power. Other related doctrines encompass the exclusionary rule, attenuation doctrine, independent-source rule, and inevitable-discovery rule.
