To repeal or undo a law or decree; to reverse or nullify an act or legislative decision.
From dis- (reversal) + enact (from en- + act, meaning to pass into law). This legal term means to undo what was formally enacted or established by law.
When legislatures want to reverse laws, they usually say they're 'repealing' them, but in older legal documents you'll find 'disenact' used for more ceremonious reversals—it shows the formal gravity of undoing laws.
