What does the "Fruit of Poisonous Tree" principle refer to in legal contexts?

The "Fruit of the Poisonous Tree" principle is a legal doctrine that seeks to exclude evidence obtained from unlawful searches or interrogation methods. When evidence is collected in violation of a person's constitutional rights, any subsequent evidence derived from that illegal activity is also generally considered inadmissible in court. This principle ensures that law enforcement is held accountable for adhering to legal standards when collecting evidence.

By invalidating confessions or evidence that originates from an unconstitutional act, such as an illegal search or coerced confession, this principle upholds the integrity of the judicial process and protects the rights of individuals. It effectively discourages law enforcement from engaging in practices that undermine constitutional protections, establishing a necessary boundary around the admissibility of evidence.

The other choices do not align with the principle. For instance, the admissibility of evidence collected legally would not be relevant here, nor would the automatic acceptance of confessions regardless of how they were obtained, as these can only be accepted when all legal procedures have been followed. The rights of the suspect during arrest are important but are handled within separate legal frameworks and do not directly summarize the implications of the "Fruit of the Poisonous Tree" doctrine.
