  • Black's Law Dictionary: 2nd Edition

    Ignorance of the [or a] law, which every one is bound to know, excuses no man. A mistake in point of law is, in criminal cases, 'no sort of defense. 4 Bl. Comm. 27; 4 Steph. Comm. 81; Broom, Max. 253 ; 7 Car. & P. 456. And, in civll cases, ignorance of the law, with a full knowledge of the facts, furnishes no ground, either in law or equity, to rescind agreements or reclaim money paid or set aside solemn acts of the parties. 2 Kent, Comm. 491, and note.
