Canon 1610

Can. 1610 §1. If there is only one judge, he will write the sentence himself.

Can. 1610 §2. In a collegiate tribunal, it is for the ponens or relator to write the sentence, selecting the reasons from those the individual judges brought forth during the discussion, unless a majority of the judges have already determined the reasons to be presented. The sentence must then be submitted for the approval of the individual judges.

Can. 1610 §3. The sentence must be issued no more than a month from the day on which the case was decided unless in a collegiate tribunal the judges set a longer period for a grave reason.
