Implied repeal

The Doctrine of Implied repeal is an idea in English constitutional theory which states that an earlier law cannot be used to amend or repeal a later law. If two laws about the same subject say different things, it will be the more recently enacted law that says what must be done. This doctrine is expressed in the Latin phrase "leges posteriores priores contrarias abrogant" - more recent law overwrites earlier law that says differently.[1]
