A feature of a rigid constitution is that it requires special amendment procedures. This means that changing the constitution is not an easy task and cannot be done by a simple majority vote or through regular legislative procedures. Instead, special procedures, such as a higher threshold for approval or a constitutional convention, may be required to make amendments to the constitution. The purpose of a rigid constitution is to ensure that the basic principles and values of the constitution are protected from arbitrary changes by those in power. By making it difficult to amend the constitution, it ensures that any changes made to the constitution are done deliberately and after careful consideration. In contrast, a flexible or "unwritten" constitution, such as that of the United Kingdom, can be amended through ordinary legislative procedures. This makes it easier to adapt to changing circumstances but also means that the constitution may be more susceptible to the whims of the government in power.
