3. Law

A formal statement of the plaintiff's case in court; in a more technical and correct sense, a particular allegation or charge in a declaration or indictment, separately setting forth the cause of action or prosecution.


⇒ In the old law books, count was used synonymously with declaration. When the plaintiff has but a single cause of action, and makes but one statement of it, that statement is called indifferently count or declaration, most generally, however, the latter. But where the suit embraces several causes, or the plaintiff makes several different statements of the same cause of action, each statement is called a count, and all of them combined, a declaration.
