235 A.3d 1075
Pa.2020Background
- Michael Bagnall was prosecuted for first-degree murder; John Gregory was the sole eyewitness.
- Gregory testified at trial that Victim begged for his life and had no gun; he repeatedly denied receiving any deal for his testimony.
- The Mercer County DA’s Office, during Gregory’s unrelated plea/sentencing, agreed to recommend a mitigated/probationary sentence “based off of his cooperation.”
- The Pennsylvania Office of Attorney General (OAG) assumed Bagnall’s prosecution after the DA was disqualified; both DA and OAG repeatedly told defense there was no cooperation/leniency agreement.
- After conviction, defense obtained Gregory’s plea transcript and elicited testimony establishing the DA’s promise of leniency tied to Gregory’s cooperation in Bagnall’s case.
- The Pennsylvania Supreme Court held the OAG is imput ed with knowledge of the DA’s agreement, found a Brady/Giglio violation (suppressed, material impeachment evidence), reversed the Superior Court, and remanded for a new trial.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether the undisclosed DA–Gregory cooperation understanding was Brady material impeachment evidence | Bagnall: the DA’s promise to mitigate Gregory’s sentence for cooperation was impeachment and thus Brady material | OAG: no material undisclosed evidence; Gregory’s plea outcome was unrelated or publicly obtainable | Held: Yes — any promise/understanding of leniency is impeachment and material here given Gregory was the sole eyewitness |
| Whether OAG’s lack of actual knowledge defeats Brady (attribution/imputation) | Bagnall: knowledge of one prosecutor’s promise must be imputed to the government; OAG assumed prosecution so it must be charged with DA’s knowledge | OAG: separate offices/governments; OAG did not know of the DA’s agreement and Kyles/Burke do not extend to cross-jurisdictional imputation here | Held: Giglio/Kyles principles apply; knowledge of the DA’s promise is imputed to OAG that assumed the prosecution |
| Whether absence of formal, written documentation defeats Brady | Bagnall: promise need not be written; an oral or tacit understanding is Brady material | OAG: no written agreement existed; nothing in forwarded file indicated a deal | Held: Rejects requirement of formal writing; oral/understood promises qualify as Brady material (citing Chmiel/Strong) |
| Whether defense could have obtained the information with due diligence (transcripts/public records) so no Brady violation occurred | OAG: plea/sentencing transcripts were publicly available; defense knew of favorable result and could have uncovered specifics pretrial | Bagnall: prosecutors repeatedly denied any deal; the plea transcript’s reference to “cooperation” was ambiguous and defense reasonably relied on prosecution’s denials | Held: Defense exercised reasonable diligence under circumstances; ambiguous transcript plus repeated denials meant defense did not have equal access — nondisclosure stands |
