Date of Decision

27 March 1979


The U.S. Supreme Court upheld the decision of the Delaware Supreme Court--that it was unconstitutional for state police to randomly stop vehicles at a check stop unless there was a justifiable reason for a motorist to be stopped. Unwarranted stops represented unreasonable seizure under the Fourth Amendment.
