One enacted for the purpose of removing doubts or putting an end to
conflicting decisions in regard to what the law is in relation to a particular matter. It
may either be expressive of the common law, (1 Bl. Comm. 86; Gray v. Bennett, 3
Mete. [Mass.] 527:) or may declare what shall be taken to be the true meaning and
intention of a previous statute, though in the latter case such enactments are more
commonly called “expository statutes.”
