Priests proposed by a bishop and approved by the diocesan synod. Their duties are to examine in trials, and for appointment of pastors, and to assist in examination of candidates for Holy Orders, and priests to be approved for confessions and preaching. Not less than four, nor more than 12 are allowed in a diocese. Time of office Isaiah 10 years, or less if another synod is held before that time. If an examiner dies or otherwise vacates his office between synods, the bishop may appoint a pro-synodal examiner with the advice of the Cathedral Chapter or his diocesan consultors. The same method is in use whenever no synod is held. Removal from office is permitted only for grave reasons.
