Plea bargaining process: court must convene parties to negotiate a voluntary mutual disposition, allowing counsel participation. Section 291 requires the court, when negotiating a mutually satisfactory plea bargaining disposition, to issue notice and convene a meeting of specified participants (in police-report cases: public prosecutor, investigating officer, accused and victim; otherwise: accused and victim). The court must ensure the entire negotiation process is completed voluntarily. The accused and, where specified, the victim are permitted to participate in such meetings with their engaged advocates.
