Canon 1322

With due regard for the prescription of can. 1324, a res iudicata

results: (1) if two concordant sentences have been issued between the same persons regarding the same petition and arising

out of the same basis for petitioning; (2) if an appeal against

the sentence has not been filed within the available time (tempus

utile); (3) if, at the appellate level, the prosecution of the

suit has been estopped or renounced; (4) if a definitive sentence has been rendered from which no appeal is granted.
