Fruit of the Poisonous Tree Exceptions: Which is an exception to the fruit of the poisonous tree doctrine?

• A. Grand Jury
• B. Good Faith Reliance by Police
• C. Intervening Act of the D
• D. Independent Source

Answer: (D)

The key idea is that the fruit of the poisonous tree rule excludes evidence that came from an illegal search or seizure, but there are recognized ways to let evidence in despite that taint. The independent source exception says that if the challenged evidence is ultimately discovered through a source that is truly independent of the illegal activity, it can be admitted. The critical point is that the discovery path must be separate from the tainted initial conduct, so the police cannot rely on information obtained from the illegal act to find or obtain the evidence again.

For example, if police illegally search a home and, because of that search, learn of a lead, but later another investigation uncovers the same evidence entirely through lawful means (unrelated to the tainted lead), that evidence may be admitted if the later discovery was independent. The independent source must be shown to have nothing to do with the initial illegality.

Other options don’t fit as cleanly because they rely on different circumstances. A grand jury context involves separate proceedings with its own rules, not a direct exception to the taint of an illegal search in the way independent source does. Good faith reliance by police is another recognized route, but it rests on police acting with a reasonable belief in the validity of their warrant or statute; the scenario here points to an independent, separate origin of the evidence.
