Pennsylvania Petition For Involuntary Treatment Via The Criminal Justice System is a process by which individuals who are facing criminal justice-related charges can seek treatment for a mental health disorder or substance abuse disorder. The petitioner, either the defendant or a family member, can petition the court for an involuntary treatment order, which is approved, would require the defendant to complete a treatment program. The petitioner must provide evidence that the defendant is suffering from a mental health disorder or substance abuse disorder and is at risk of harm to himself or others if not treated. There are two types of petitions for involuntary treatment via the criminal justice system in Pennsylvania: 1) Petition For Inpatient Treatment and 2) Petition For Outpatient Treatment. With an Inpatient Treatment petition, the court can order the defendant to receive treatment at a hospital or other inpatient facility. With an Outpatient Treatment petition, the court can order the defendant to receive treatment at a mental health or substance abuse clinic or other outpatient facility.
