The ‘Gagnon’ hearing process is named after the United States Supreme Court Case of Gagnon v. Scarpelli in which the Court mandated a two step revocation procedure. The first step is the Gagnon I hearing. You are entitled to a Gagnon I hearing if you are in detention while awaiting your Gagnon II, or formal revocation hearing. The Gagnon I hearing is a pre-revocation hearing. At the Gagnon I hearing the adult probation officer must prove that probable cause exists to believe that a violation has been committed. However, the ‘probable cause standard’ is a low burden of proof for the probation officer. The purpose of this hearing is to protect against unlawful detention and serves as an additional safeguard for probationers or parolees. The Gagnon I hearing is informal and will be held before a hearing officer. The hearing will usually occur in the adult probation and parole office.
If probable cause is found at the Gagnon I hearing, the case will proceed to a Gagnon II hearing. This is the ultimate hearing that will determine if you have violated the conditions of probation or parole. The Gagnon II hearing will be scheduled before a Court of Common Pleas Judge in a courtroom. It is a more formal hearing. The first issue in a Gagnon II hearing is whether you violated one of the conditions of your probation or parole. You have the right to a hearing on this issue. The Commonwealth must prove the violation by a preponderance of the evidence – which means ‘more likely than not.’
