A report on Constitutional amendment, Parliamentary sovereignty and Constitution

A constitutional amendment is a modification of the constitution of a polity, organization or other type of entity.

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, not even a constitution) or by precedent.

A Finnish peculiarity is that the parliament can make exceptions to the constitution in ordinary laws that are enacted in the same procedure as constitutional amendments.

In addition, exceptional procedures are often required to amend a constitution.

In the United Kingdom, devoid of a written constitution and exercising pure parliamentary sovereignty, the final authority on all quasi-constitutional matters is ultimately the parliament itself (the legislature), by a simple majority.

In the UK, the constitutional doctrine of Parliamentary sovereignty dictates that sovereignty is ultimately contained at the centre.
