In relation to the exclusionary rule, what does 'fruit of the poisonous tree' refer to?

• A. Evidence derived from illegal police conduct
• B. A Type of Fruit
• C. A Search Warrant
• D. A Confession Obtained by Trickery

Answer: (A)

The central idea here is that the exclusionary rule not only blocks evidence obtained directly through illegal police action, but also blocks other evidence that flows from that illegality. “Fruit of the poisonous tree” is a metaphor: the illegal act is the tree, and the evidence discovered as a result—the fruit—should be excluded because its origin is tainted. For example, if an unlawful search leads to more information or a confession gathered afterward, those items can be kept out of court since they stem from the initial violation. It’s not a literal fruit or a search warrant, and while there are exceptions that might allow tainted evidence in some cases, the phrase specifically describes the chain of tainted evidence that follows illegal conduct.
