Coyle v. Pennsylvania

Opinion summary

Etalia.ai summary of the majority opinion

The case involved the appellant, Coyle, who was convicted of robbery in Pennsylvania. During his trial, evidence obtained from a search conducted without a warrant was admitted. Coyle argued that this violated his Fourth Amendment rights against unreasonable searches and seizures. The Supreme Court examined whether the admission of such evidence constituted reversible error under the exclusionary rule established in Mapp v. Ohio (1961), which mandates that illegally obtained evidence is inadmissible in state courts. The Court ultimately held that even if there were errors related to admitting certain pieces of evidence during trial, these did not have substantial influence on the outcome given other overwhelming admissible proof presented against Coyle.
