Canon 1310

There is no room for appeal: (1) from a sentence of the Roman

Pontiff himself or of the Apostolic Signatura; (2) from a sentence vitiated by nullity unless it is joined with a complaint of

nullity according to the norm of can. 1306; (3) from a sentence

which has become res iudicata; (4) from the decree of a judge or

an interlocutory sentence which does not have the force of a definitive sentence, unless it is joined with an appeal from a definitive sentence; (5) from a sentence or from a decree in a

case in which the law provides for settlement of the matter most

expeditiously (expeditissime).
