ANTECEDENT. Something that goes before. In the construction of laws, agreements, and the like, reference is always to be made to the last antecedent; ad proximun antecedens fiat relatio. But not only the antecedents but the subsequent clauses of the instrument must be considered: Ex antecedentibus et consequentibus fit optima interpretatio.
