What does "Fruits of the Poisonous Tree" refer to in legal terms?

"Fruits of the Poisonous Tree" is a legal doctrine that pertains to evidence obtained as a result of illegal actions, typically violations of the Fourth Amendment, which protects against unreasonable searches and seizures. This principle asserts that if the source of the evidence is tainted by illegal acts, then any evidence derived from that source is also inadmissible in court.

In this context, "poisonous tree" symbolizes the improper police conduct or constitutional violation, while the "fruits" are the resulting evidence collected. This doctrine serves to uphold the integrity of the judicial system by discouraging law enforcement from engaging in unlawful methods of obtaining evidence. This means that if evidence is obtained through unlawful means, not only is that evidence inadmissible, but any further evidence derived from it will also be considered tainted and thus excluded from legal proceedings.

The other options do not describe this concept accurately. Witness testimony and evidence from public records are not inherently linked to illegal acquisition, while confessions can be admissible even if conducted under certain questionable circumstances, as long as they weren't coerced. This is why the correct interpretation is specifically evidence obtained illegally as it directly relates to the essence of the "Fruits of the Poisonous Tree" doctrine.
