Causa 13 (14), Cambridge, Fitzwilliam Museum, Cutting It. 5

 Summa Parisiensis: Ponit <Gratianus> ergo thema, format questiones et exsequitur, sed diverso modo ab aliis causis.  Hic enim non solum decreta, sed etiam allegationes actoris modo postea <rei> et iterum huius  responsiones et illius inducit.

Summa Parisiensis:  Gratian poses this theme and the following questions, but in a way that is different from the other Cases.  Here he cites not only canons but also the allegations of the plaintiff and defendant (actor et reus) with their responses to each other.
