ROCHIN v. CALIFORNIA
Rochin swallowed drug capsules to dispose of evidence. The police pummeled him and jumped on his stomach in a vain effort to make him throw up. They took him to a hospital where a doctor was instructed by the police officers to administer an emetic by forceably passing a tube into Rochin's stomach. He vomited the capules and was convicted on the basis of the evidence produced from his vomit.
Did the police procedure forcing Rochin to vomit violate the Fifth Amendment privilege against self-incrimination and the Due Process Clause of the 14th Amendment?
The Court reversed the conviction. The police violated Rochin's right to due process of law. Due process was an admittedly vague concept, but it prohibited "conduct that shocks the conscience." This nebulous approach was mocked in a concurring opinion by Justice Black.
