Quando dispositio referri potest ad duas res

Quando dispositio referri potest ad duas res, ita quod secundum relationem unam vitiatur et secundum alteram utilis sit, tum facienda est relatio ad illam ut valeat dispositio. When a disposition may be made to refer to two things, so that according to one reference, it would be vitiated, and by the other it would be made effectual, such a reference must be made to the disposition which is to have effect. 6 co. 76.
