Ex antecedentibus et consequentibus fit optima interpretatio

Definition of Ex antecedentibus et consequentibus fit optima interpretatio

A passage in a statute is best interpreted by reference to what precedes and what follows it. The best interpretation [of a part of an instrument] is made from the antecedents and the consequents [from the preceding and following parts]. The law will judge of a deed or other instrument, consisting of divers parts or clauses, by looking at the whole; and will give to each part its proper office, so as to ascertain and carry out the intention of the parties. The whole instrument is to be viewed and compared in all its parts, so that every part of it may be made consistent and effectual.
