A repeal is the removal or reversal of a law. There are two basic types of repeal, a repeal with re-enactment (or replacement) of the repealed law, or a repeal without replacement. The motion to rescind, repeal, or annul is used in parliamentary procedure to cancel or countermand an action or order previously adopted by the assembly. Removal of secondary legislation is normally referred to as revocation rather than repeal in the United Kingdom and Ireland. Under the common law of England and Wales, the effect of repealing a statute was "to obliterate it completely from the records of Parliament as though it had never been passed." This, however, is now subject to savings provisions within the Interpretation Act 1978. - Source: Wikipedia
