MAPP V. OHIO
By: Will C. & Greg W.
Issue at hand
Dollree Mapp was arrested for possessing illegal items. The evidence that was used in court was illegally obtained by a search of Dollree's home without a warrant. Child pornography was used against Dollree in court, ultimately convicting her. Dollree appealed her conviction on the terms of freedom of expression.
Decision
A search warrant was not presented in court and the judge deemed the evidence obtained invalid due to illegal search and seizure. On June 19, 1961 the decision was ruled 6-3 in favor of Dollree Mapp. The court declared that "all evidence obtained by searches and seizures in violation of the Constitution is inadmissible in a state court."
Impact
The decision established the exclusionary rule, which states that all illegally obtained evidence (violating the 4th Amendment) is excluded from use in court at all levels of government.
