If an arrest is unlawful, which doctrine may suppress evidence obtained as a result?

• A. Good Faith Rule
• B. Fruit of the Poisonous Tree Doctrine
• C. Exclusionary Rule
• D. Miranda Rights

Answer: (B)

When an arrest is unlawful, the evidence obtained as a result can be suppressed under the Fruit of the Poisonous Tree doctrine. This rule extends the exclusionary principle to not only the unlawfully seized items but also any additional evidence that derives from the initial illegality—such as further searches, seized items found during those searches, or statements obtained as a result of the unlawful arrest. The idea is to deter police misconduct by preventing such tainted evidence from being used in court. There are limited exceptions, like independent discovery or attenuation, but in general the derivative evidence stays excluded. The other options don’t directly address suppression of evidence stemming from an illegal arrest: Miranda rights concern warnings to prevent compelled statements, the Good Faith Rule can apply in certain warrant situations but does not focus on tainted derivative evidence, and the Exclusionary Rule is the broad principle, while the specific doctrine for taint from illegal arrests is the Fruit of the Poisonous Tree.
