Definition of Edict
A formal decree, command, or proclamation. A positive law promulgated by the sovereign of a country and having reference either to the whole land or some of its divisions, but usually relating to affairs of state. It differs from a “public proclamation,” in that it enacts a new statute, and carries with it the authority of law, whereas the latter is, at most, a declaration of a law before enacted. In Roman law, sometimes, a citation to appear before a judge. A “special edict” was a judgment in a case; a “general edict” was in effect a statute. See Decree; Edictum; Mandate.
