rochin rule
Rochin rule. The now-rejected principle that unconstitutionally obtained evidence is admissible against the accused unless the evidence was obtained in a manner that shocks the conscience (such as pumping the stomach of a suspect to obtain illegal drugs that the suspect has swallowed, as occurred in the Rochin v. California case). • The Supreme Court handed down Rochin before the Fourth Amendment exclusionary rule applied to the states. Rochin v. California, 342 U.S. 165, 72 S.Ct. 205 (1952).
