Change of Law

Change of Law.—The growth of knowledge and experience, or the change of social circumstances, requires now and then that human laws be improved or adapted to new conditions. But, since laws derive a great part of their influence from custom, they should not be changed unless the break with custom is compensated for by the urgent necessity of the new law, by its manifest advantage, or by the evident iniquity or harmfulness of the old law, In brief, the common good should be the norm by which to decide whether a law should be retained or changed.

Constitutional law, as being fundamental and organic, is more immutable than ordinary law. (a) If given to a society established according to the positive ordinance of a superior, it cannot be abrogated or modified by the legislative authority of that society, since this would be contrary to the will of the founder. Hence, the Church has no power to change the fundamental constitution given her by Christ, who prescribed the religious society as established by Him to be necessary. (b) If a constitutional law is given to a society which is perfect and necessary from the law of nature, such constitution can be modified for extraordinary reasons and in the special ways provided (e.g., by amendments approved by the people).
