Can. 1644

§1. If a second concordant sentence has been rendered in a case concerning the status of persons, recourse can be made at any time to the appellate tribunal if new and grave proofs or arguments are brought forward within the peremptory time limit of thirty days from the proposed challenge. Within a month from when the new proofs and arguments are brought forward, however, the appellate tribunal must establish by decree whether a new presentation of the case must be admitted or not.

§2. Recourse to a higher tribunal in order to obtain a new presentation of the case does not suspend the execution of the sentence unless either the law provides otherwise or the appellate tribunal orders its suspension according to the norm of can. 1650, §3.
