The rule that evidence, no matter how incriminating, cannot be introduced into a trial if it was not constitutionally obtained. The rule prohibits use of evidence obtained through unreasonable search and seizure.
The situation occurring when an individual accused of a crime is compelled to be a witness against himself or herself in court. The Fifth Amendment forbids this.
