Repeal
On occasions, legislation within both micro- and macronational legislatures can change or revoke certain aspects of other legislation passed by that legislature. This is what is known as a repeal, and it can come in two different forms - partial and full.
Different types of repeal
A partial repeal is when only an aspect of a law or piece of legislation is revoked, while the other provisions of the legislation remain in force.
A full repeal is when the entirety of a law or piece of legislation is revoked.
Unrepealable legislation
Some legislative documentation prevents parliaments and other deliberative assemblies from passing acts of legislation that are unrepealable. The Partisan Democracy Act, passed by the Mercian Parliament House, is one exception to this rule - as a constituting document for the Parliament itself, the Mercian Parliament cannot repeal or amend it without prior approval from the Lords, the absolute diarchy of the country.
