What is Parliamentary sovereignty?

Parliamentary sovereignty 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 or by precedent.

In some countries, parliamentary sovereignty may be contrasted with separation of powers, which limits the legislature's scope often to general law-making and makes it subject to external judicial review, where laws passed by the legislature may be declared invalid in certain circumstances.

Many states have sovereign legislatures, including the United Kingdom, New Zealand, the Netherlands, Sweden, Norway, Denmark, Finland, Iceland, Barbados, Jamaica, Papua New Guinea, the Solomon Islands, and Israel.
