Pennsylvania v. Bagnall (majority)
Annotate this CaseThe issue presented for the Pennsylvania Supreme Court's review in this case was whether the Mercer County, Pennsylvania District Attorney's Office, and later the Pennsylvania Office of the Attorney General, violated the due process rights of Appellant Michael Bagnall under Brady v. Maryland, 373 U.S. 83 (1963) when it failed to disclose a cooperation agreement between the DA's Office and a key witness in Appellant's murder prosecution. The issue arose under circumstances where the OAG assumed the prosecution of Appellant prior to trial due to a conflict of interest between the DA’s Office and Appellant’s defense counsel, and the OAG was never made aware of the existence of the agreement. After review of the trial court record, the Pennsylvania Supreme Court held the OAG was imputed with knowledge of the agreement between the DA’s Office and the key witness at Appellant’s trial, and that, having satisfied all of the requirements for establishing a Brady violation, Appellant was entitled to a new trial. Because the Superior Court reached a contrary result, the Supreme Court reversed and remanded.
