 Couperrie died shortly afterwards, and was succeeded as apostolic vicar by his assistant Laurent Trioche, who was consecrated a bishop for the purpose by Yohannan and the metropolitan Lawrent Shoa of Kirkuk on the Vatican's instructions.Like his predecessor, Trioche took Yohannan's part, and in a consistory held in the Vatican on 5 July 1830 it was agreed that Yohannan should be relieved of the archdiocese of Mosul, confirmed as patriarch of the Chaldeans and awarded the pallium (the traditional symbol of the Vatican's recognition of his succession).The decision was communicated to Yohannan Hormizd, now aged 74, in two papal bulls of the same date.
