Fruit of the poisonous tree is an American legal doctrine:
This doctrine holds that evidence gathered with the assistance of illegally obtained information must be excluded from trial. Thus, if an illegal interrogation leads to the discovery of physical evidence, both the interrogation and the physical evidence may be excluded, the interrogation because of the exclusionary rule, and the physical evidence because it is the “fruit” of the illegal interrogation.
