.. no direct mention of the status of the (ex-?) bishops of Belgium and Jazira and the status of the priest that the latter ordained.
Mor Eusthathius Matta Roham, who was the Archbishop of Jezira and the Euphrates; by himself abandoned his flock at the most critical time for the folk and fled to Austria. The Synod gave him 6 months to return to his Archdiocese and take care of the flock; which he didnot, but chose to stay in the safety offered by Europe. So a new Archbishop was installed for Jezira and the Euphrates. I am not sure how you can revisit that.
So Mor Eusthathius Matta Roham, is now a general bishop with no diocese assigned. And no canon allows an archbishop to ordain a priest outside his archdiocese. So anybody an archbishop who has fled his archdiocese ordains within the jurisdiction of another bishop is not a canonically ordained priest.
