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.

Real-world examples

Here are a couple of examples of abatement:

Example 1: A police officer conducts a search without a warrant and finds illegal drugs. If the drugs are deemed inadmissible, any statements made by the suspect about the drugs after the search may also be excluded.

Example 2: A person confesses to a crime after being illegally detained. If the confession is obtained through coercion, it may not be used in court, nor can any evidence found as a result of that confession be used. (hypothetical example)
