Use of restraints on juveniles in court prohibited; exceptions. Prohibits the use of instruments of restraint, as defined in the bill, on a juvenile appearing before the juvenile and domestic relations district court unless, upon motion of the attorney for the Commonwealth or upon the court's own motion, the court orders the use of restraints upon a finding that (i) the use of such restraints is necessary (a) to prevent physical harm to such juvenile or another person, (b) because such juvenile has a history of disruptive courtroom behavior that has placed others in potentially harmful situations or presents a substantial threat of serious harm to himself or others as evidenced by recent behavior, or (c) because such juvenile presents a substantial risk of flight from the courtroom and (ii) there are no less restrictive alternatives to such restraints that will prevent flight of or harm to such juvenile or another person, including court personnel or law-enforcement officers. The bill requires the court to provide the juvenile's attorney an opportunity to be heard before the court orders the use of instruments of restraint, and if such restraints are ordered, requires the court to make written findings of fact in support of the order.
