What is a Mapp Hearing? A Guide to Evidence Suppression in Law

Definition & Meaning

A Mapp hearing is a pre-trial legal proceeding that focuses on whether specific evidence should be excluded from a trial due to being obtained through illegal search and seizure. This type of hearing is primarily concerned with both tangible evidence, like physical items, and intangible evidence, such as statements or confessions. The purpose of the Mapp hearing is to protect individuals' rights by ensuring that evidence collected in violation of the Fourth Amendment is not used against them in court.
