The following is the 2012-2016 complaint process outlined for clergy in The Book Of Discipline paragraph 2701 and following. Note that the process no longer includes the Committee on Investigation. The process is different for clergy and bishops.
Supervisory Response Process: Just Resolution
Administrative or Judicial Track: Hearing or Trial
*Already accrued pension benefits cannot be lost even if a clergy person is dismissed through either the Administrative Track or the Judicial Track.
The processing of a complaint against a bishop begins with supervision which is described in Para. 413. It appears that there is one bishop from the college and two members selected from the jurisdictional committee on episcopacy who actually oversee the supervision. And it appears that the chair of the committee on episcopacy choses the 2 members after consultation with the president and secretary of the college of bishops. (It is NOT the college who chooses the 2 members)
Note that if the complaint is dismissed in supervision that there is NO appeal of the dismissal. It ends there. And a complaint may be dismissed over the objections of the person filing it.
If the complaint leaves supervision, it goes to the jurisdictional committee on investigation (the 2012 GC eliminated this committee for clergy but not bishops or lay people). A dismissal by the committee on investigation can ultimately be appealed to the Judicial Council. There is precedent for the Judicial Council ordering a committee on investigation to vote out complaints.
If the Committee on Investigation votes out complaints, then there is a trial under provisions of Para. 2712. Note that the members of the trial court are clergy from across the jurisdiction, named to the pool of potential trial court members by the bishops. The trial is NOT by the college of bishops. If there is an acquittal,there is NO provision for an appeal to the Judicial Council or any other body. If there is a conviction, the conviction and/or the penalty can be appealed — first to the jurisdictional committee on appeals, but ultimately the Judicial Council.
