Inevitable Discovery
What does "Inevitable Discovery" mean in law?
The inevitable discovery doctrine, recognized by the Supreme Court in Nix v. Williams (1984), is an exception to the exclusionary rule that allows the admission of evidence obtained through an unconstitutional search or seizure if the prosecution can demonstrate by a preponderance of the evidence that the evidence would have been inevitably discovered through lawful means independent of the constitutional violation. The doctrine is grounded in the principle that the prosecution should not be placed in a worse position than it would have been absent the police misconduct, but neither should it benefit from the illegality. Courts apply this exception when there is a demonstrated, ongoing lawful investigation or procedure that would have uncovered the same evidence regardless of the violation.

Example
Although police learned the location of the victim's body through an illegal interrogation, the court admitted the evidence because a systematic search party was already approaching the area and would have inevitably discovered the body within hours.
