A legal maxim is an established principle or proposition of law, and a species of aphorism and general maxim. The word is apparently a variant of the Latin maxima, but this latter word is not found in extant texts of Roman law with any denotation exactly analogous to that of a legal maxim in the Medieval or modern definition, but the treatises of many of the Roman jurists on regular definitiones and sententiae iuris are to some degree collections of maxims. Most of the Latin maxims originate from the Medieval era in European states that used Latin as their legal language.
The attitude of early English commentators towards the maximal of the law was one of unmingled adulation. In Thomas Hobbes, Doctor and Student (p. 26), they are described as of the same strength and effect in the law as statutes. Not only, observes Francis Bacon in the preface to his collection of maxims: The use of maxims will be "in deciding doubt and helping soundness of judgment, but, further, in gracing argument, in correcting unprofitable subtlety, and reducing the same to a more sound and substantial sense of law, in reclaiming vulgar errors, and, generally, in the amendment in some measure of the very nature and complexion of the whole law".
A similar note was sounded in Scotland; and it has been well observed that a glance at the pages of Morison’s Dictionary of Decisions or at other early reports will show how frequently in the older Scots law questions respecting the rights, remedies and liabilities of individuals were determined by an immediate reference to legal maxims.
In later times, less value has been attached to the maxims of the law, as the development of civilization and the increasing complexity of business relations have shown the necessity of qualifying the propositions which they enunciate. But both historically and practically, they must always possess interest and value.
