Canon 1091

1. The judicial vicar or the adjutant judicial vicar presides

over a collegiate tribunal insofar as this is possible. 2. The

president of a collegiate tribunal must assign one of the collegiate judges as the ponens, unless he wishes to fulfill this

function himself. 3. For a just cause the same president may

substitute another in place of the ponens. 4. The ponens reports on the case at the meeting of the judges and puts the sentence into writing.
