A constitutional amendment that is cumbersome is usually described as "rigid". This is because a rigid constitution is difficult to amend, and the process is often cumbersome, requiring a high level of consensus and agreement among different branches of government or political parties. In a rigid constitution, the amendment process is deliberately made difficult to ensure that any changes to the constitution are well-considered and not made impulsively. This is in contrast to a flexible constitution, where the amendment process is relatively easy and can be done through a simple majority vote.
