Case, in law, a formal statement of facts agreed upon by the parties, or stated by a judge, with a view to obtaining the judgment of the court thereon. Formerly in England cases were sometimes directed by the court of chancery, in suits pending therein, for the judgment of the common law courts, but this practice is now abolished. - Action on the case, or trespass on the case, is a form of personal action, first used in the reign of Edward III., as a remedy for injuries to which the forms then in vogue were not adapted, and receiving its name from the fact that the case of the plaintiff was set forth in the original writ. It is so comprehensive in its scope as to lie wherever a party has sustained a legal injury to person or property, for which no other form of action affords a remedy. This, which may be called a natural species of action, in contradistinction from those which are of a more technical character, is retained in the codes which have recently been adopted in several of the American states, the purpose of which has been to simplify pleadings and proceedings at law.
