Canon 1128

1. A judge who has been forcibly expelled from his own territory or has been impeded in the exercise of judicial power there

can exercise his power and render a sentence outside that territory; however, the eparchial bishop of the place should be informed of this fact by the judge. 2. Besides the case mentioned in 1, for a just cause and after hearing the parties, a

judge can travel outside his own territory in order to acquire

proofs with the permission of the eparchial bishop of the place

he enters and at a site designated by the bishop.
