  • Black's Law Dictionary: 2nd Edition

    Not authorized by law; illicit; unlawful; contrary to law. Sometimes this term means merely that which lacks authority of or support from law; but more frequently it imports a violation. Etymologically, the word seems to convey the negative meaning only. But in ordinary use it has a severer, stronger signification; the idea of censure or condemnation for breaking law is usually presented. But the law implied in illegal is not necessarily an express statute. Things are called "illegal" for a violation of common-law principles. And the term does not imply that the act spoken of is immoral or wicked; it implies only a breach of the law. See State v. Haynorth, 3 Sneed (Tenn.) 65; Tiedt v. Carstensen, 61 Iowa, 334, 16 N. W. 214; Chadboume v. Newcastle, 48 N. H. 199; People v. Kelly, 1 Abb. Prae. N. S., (N. Y.) 437; Ex parte Scwartz, 2 Tex. App. 80.
