Natural Equity

That which is founded in natural justice, in honesty and right, and which arises ex aequo et bono. It corresponds precisely with the definition of justice or natural law, which is a constant and perpetual will to give to every man what is his. This kind of equity embraces so wide a range that human tribunals have never attempted to enforce it. Every code of laws has left many matters of natural justice or equity wholly unprovided for,, from the difl Sculty of framing general rules to meet them, from the almost impossibility of enforcing them, and from the doubtful nature of the policy of attempting to give a legal sanction to duties of imperfect obligation, such as charity, gratitude, or kindness. 4 Bouv. Inst, note 3720.

A term sometimes employed in works on jurisprudence, possessing no very precise meaning, but used as equivalent to justice, honesty, or morality in business relations, or man's innate sense of right dealing and fair play. Inasmuch as equity, as now administered, is a complex system of rules, doctrines, and precedents, and possesses, within the range of its own fixed principles, but little more elasticity than the law, the term "nafurai equity" may be understood to denote, in a general way, that which strikes the ordinary conscience and sense of justice as being fair, right, and equitable, in advance of the question whether the technical jurisprudence of the chancery couris would so regard it.
5. Equity also signifies an equitable right, i. e., a right ehforceable in a court of equity; hence, a bill of complaint which did not show that the plaintiff had a right entitling him to relief was said to be demurrable for want of equity; and certain rights now recognized in all the courts are still known as "equities," from having been originally recognized only in the court of chancery.
