Canon 1304

1. A sentence is vitiated by remediable nullity only, if: (1)

it was rendered by an illegitimate number of judges contrary to

the prescription of can. 1084; (2) it does not contain the motives, that is, the reasons for the decision; (3) it lacks the

signatures prescribed by law; (4) it does not contain reference

to the year, month, day and place in which it was pronounced; (5)

it is based on a judicial act which is null and whose nullity was

not sanated according to the norm of can. 1302; (6) it was rendered against a party who was legitimately absent as provided for

in can. 1273, 2. 2. The complaint of nullity in these cases

can be proposed within three months from the notification of

publication of the sentence.
