Parliamentary sovereignty (also called
parliamentary supremacy or
legislative supremacy) is a concept in the
constitutional law of some
parliamentary democracies. It holds that the
legislative body has absolute
sovereignty, and is supreme over all other government institutions, including
executive or
judicial bodies. It also holds that the legislative body may change or repeal any previous legislation, and so it is not bound by written law (in some cases, even a
constitution) or by precedent.
