Canon 224

1. When the see becomes vacant, the protosyncellus and the

syncelli immediately cease from office unless they are: (1)

ordained bishops; (2) constituted in the eparchy of the patriarch; (3) constituted in an eparchy located inside the territorial boundaries of a patriarchal Church, until the administrator of the eparchy takes canonical possession of his office.

2. Those things legitimately done by the protosyncellus and

syncelli have full force until they have received certain notice

of the vacancy of the eparchial see; when the vacancy is certain,

they cease from office immediately. 3. When the eparchial see

is vacant, the auxiliary bishop retains the power which he enjoyed as protosyncellus or syncellus when the see was occupied

and which is conferred upon him by the law; this authority is to

be exercised under the authority of the administrator of the

eparchy unless otherwise determined by the Apostolic See or by

the particular law of his own patriarchal Church.
