There are two prin-cipal reasons for the deviation from that traditional rule: (i) to policethe law enforcement agencies by excluding evidence illegally ob-tained, and (2) to protect fully the civil rights of a defendant fromany infringement.It is apparent that the first basis is not applicable in the Lebelcase.
A companion to the exclusionary rule is the fruit of the poisonous tree doctrine. Under this doctrine, a court may exclude from trial not only evidence that itself was seized in violation of the Constitution but also any other evidence that is derived from an illegal search.or the more than 100 years after its ratification, the Fourth Amendment was of little value to criminal defendants because evidence seized by law enforcement in violation of the warrant or reasonableness requirements was still admissible during the defendant's prosecution.
