What is the concept of 'Fruits of a Poisonous Tree' in law enforcement?

The concept of 'Fruits of a Poisonous Tree' refers to the legal principle that any evidence obtained as a result of an illegal search, seizure, or arrest is inadmissible in court. This principle is rooted in the exclusionary rule, which is designed to deter law enforcement from conducting unlawful actions. When a confession or any evidence is derived from an unlawful arrest, it taints the legitimacy of that evidence, making it inadmissible in legal proceedings.

This notion serves as an important safeguard in protecting individuals' rights against unlawful actions by law enforcement and upholds the integrity of the judicial system. By ensuring that evidence or confessions obtained through illegal means cannot be used in court, the legal system reinforces the principle that law enforcement must adhere to constitutional and legal standards during an investigation.

The other options do not accurately reflect this legal principle. Some suggest scenarios where evidence might still be admissible despite initial illegality, but the 'Fruits of a Poisonous Tree' doctrine explicitly negates this, maintaining that evidence obtained through such means remains inadmissible.
