The exclusionary rule also excludes additional evidence that is derived directly from an illegal search. This is described by which doctrine?

• A. Fruit of the poisonous tree
• B. Direct consequence rule
• C. Chains of evidence doctrine
• D. Plain view doctrine

Answer: (A)

When a search violates the Fourth Amendment, the exclusionary rule blocks not only the evidence seized directly but also any evidence that flows from that illegal search. This is the fruit of the poisonous tree doctrine: the “poisonous tree” is the illegal search, and the “fruit” is the additional evidence derived from it. The aim is to deter unlawful police conduct by preventing tainted evidence from being used in court. There are exceptions (like good faith, inevitable discovery, or attenuation), but the central idea remains that derivative evidence obtained as a result of an illegal search is generally excluded.
