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.
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."
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.
