STATUTES also are either _declaratory_ of the common law, or _remedial_ of some defects therein. Declaratory, where the old custom of the kingdom is almost fallen into disuse, or become disputable; in which case the parliament has thought proper, _in perpetuum rei testimonium_, and for avoiding all doubts and difficulties, to declare what the common law is and ever hath been. Thus the statute of treasons, 25 Edw. III. cap. 2. doth not make any new species of treasons; but only, for the benefit of the subject, declares and enumerates those several kinds of offence, which before were treason at the common law. Remedial statutes are those which are made to supply such defects, and abridge such superfluities, in the common law, as arise either from the general imperfection of all human laws, from change of time and circumstances, from the mistakes and unadvised determinations of unlearned judges, or from any other cause whatsoever. And, this being done either by enlarging the common law where it was too narrow and circumscribed, or by restraining it where it was too lax and luxuriant, this has occasioned another subordinate division of remedial acts of parliament into _enlarging_ and _restraining_ statutes. To instance again in the case of treason. Clipping the current coin of the kingdom was an offence not sufficiently guarded against by the common law: therefore it was thought expedient by statute 5 Eliz. c. 11. to make it high treason, which it was not at the common law: so that this was an _enlarging_ statute. At common law also spiritual corporations might lease out their estates for any term of years, till prevented by the statute 13 Eliz. beforementioned: this was therefore a _restraining_ statute. SECONDLY, the rules to be observed with regard to the construction of statutes are principally these which follow.
