Understanding the Fruit of the Poisonous Tree Doctrine in Law
Definition & meaning
The "fruit of the poisonous tree" is a legal principle in evidence law. It asserts that if evidence is obtained through illegal means, that evidence cannot be used in court. Furthermore, any additional evidence or testimony that arises from the illegally obtained evidence is also considered inadmissible. This concept emphasizes that if the original source of evidence is tainted, any resulting evidence is likewise tainted.
