The American Exclusionary Rule

Abstract

When the U.S. Supreme Court extended the application of the exclusionary rule in its landmark decision Mapp v. Ohio, it was leading the way in employing the exclusionary remedy as a means to protect people’s rights against unreasonable searches and seizures. The past 50 years have seen significant changes in the criminal justice landscape on the world scene. The exclusionary rule is no longer unique to American jurisprudence. The rule has been adopted by other Western countries as well. The American exclusionary rule, however, remains a unique rule in terms of its deterrence rationale and mandatory nature. No other countries have adopted a mandatory rule or rested the rule on its deterrent effect. This article discusses the operation of the exclusionary rule in four other countries and provides a comparative analysis of the American exclusionary rule. It analyzes the problems associated with the operation of a deterrence-based mandatory rule and explores the possibility of changing the American exclusionary rule from a mandatory to a discretionary rule. The analysis takes note especially two recent U.S. Supreme Court decisions that signal significant changes in the application of the exclusionary rule in the United States.
