Canon 999

1. Before proposing some recourse, a person must seek the revocation or emendation of the decree in writing from its author

within a peremptory period of ten days from legal notice of the

decree; when such a petition is proposed it is understood by the

law itself that the suspension of the execution of the decree is

also being petitioned. 2. The obligation of petitioning the

revocation or emendation of a decree does not bind if it concerns

the first recourse against a decree mentioned in can. 997, 2, or

if it concerns further recourse except for recourse against decrees of the eparchial bishop, by which a first recourse has been

decided.
