Council of Trent: Session XIII, Reformation, Chapter II

CHAPTER II. An appeal from the bishop in criminal causes, when to be committed to the Metropolitan, or to one of the nearest bishops.

A case of appeal-where there is room for such appeal-from the sentence of the bishop, or that of his vicar general, shall, if it happen to be a case committed by apostolic authority to judges on the spot, be referred to the metropolitan, or even to his vicar general in spirituals; or if that metropolitan be for some cause suspected, or be distant more than two days' journey as settled by law, or if it be from him that the appeal is made, the case shall be committed to one of the nearest bishops, or to the vicars thereof, but not to inferior judges.
