What does the "Fruit of the Poisonous Tree" doctrine prohibit?

• A. Only the use of physical evidence in court
• B. Evidence derived from an unlawful search and testimony concerning knowledge acquired from that search
• C. The arrest of individuals without just cause
• D. The questioning of witnesses without proper notification

Answer: (B)

The "Fruit of the Poisonous Tree" doctrine is a legal principle that extends the exclusionary rule, which asserts that evidence obtained through illegal means must be excluded from use in court. Specifically, this doctrine prohibits the use of evidence that is derived from an unlawful search or seizure, as well as any testimony that stemmed from that evidence.

In this context, if the initial search was conducted without a warrant or probable cause, any physical evidence discovered during that search and any subsequent statements or testimony derived from that evidence cannot be used in a court of law. This serves to deter law enforcement from engaging in unlawful practices during investigations and upholds the integrity of the judicial process by ensuring that only evidence obtained legally can be admitted in court. Thus, the correct answer aligns precisely with this understanding of the doctrine.
