The next instrumentality by which the adaptation of law to social wants is carried on I call Equity, meaning by that word any body of rules existing by the side of the original civil law, founded on distinct principles and claiming incidentally to supersede the civil law in virtue of a superior sanctity inherent in those principles. The Equity whether of the Roman Praetors or of the English Chancellors, differs from the Fictions which in each case preceded it, in that the interference with law is open and avowed. On the other hand, it differs from Legislation, the agent of legal improvement which comes after it, in that its claim to authority is grounded, not on the prerogative of any external person or body, not even on that of the magistrate who enunciates it, but on the special nature of its principles, to which it is alleged that all law ought to conform. The very conception of a set of principles, invested with a higher sacredness than those of the original law and demanding application independently of the consent of any external body belongs to a much more advanced stage of thought than that to which legal fictions originally suggested themselves.
Legislation, the enactments of a legislature which, whether it take the form of an autocratic prince or of a parliamentary assembly, is the assumed organ of the entire society, is the last of the ameliorating instrumentalities. It differs from Legal Fictions just as Equity differs from them, and it is also distinguished from Equity, as deriving its authority from an external body or person. Its obligatory force is independent of its principles. The legislature, whatever be the actual restraints imposed on it by public opinion, is in theory empowered to impose what obligations it pleases on the members of the community. There is nothing to prevent its legislating in the wantonness of caprice. Legislation may be dictated by equity, if that last word be used to indicate some standard of right and wrong to which its enactments happen to be adjusted; but then these enactments are indebted for their binding force to the authority of the legislature and not to that of the principles on which the legislature acted; and thus they differ from rules of Equity, in the technical sense of the word, which pretend to a paramount sacredness entitling them at once to the recognition of the courts even without the concurrence of prince or parliamentary assembly. It is the more necessary to note these differences, because a student of Bentham would be apt to confound Fictions, Equity, and Statute law under the single head of legislation. They all, he would say, involve law-making; they differ only in respect of the machinery by which the new law is produced. That is perfectly true, and we must never forget it; but it furnishes no reason why we should deprive ourselves of so convenient a term as Legislation in the special sense. Legislation and Equity are disjoined in the popular mind and in the minds of most lawyers; and it will never do to neglect the distinction between them, however conventional, when important practical consequences follow from it.
