Question

what is constitutional amendments what are its uses​

Answer 1

A constitutional amendment is a modification of the constitution of a polity, organization or other type of entity. Amendments are often interwoven into the relevant sections of an existing constitution, directly altering the text.

There are a number of formal differences, from one jurisdiction to another, in the manner in which constitutional amendments are both originally drafted and written down once they become law. In some jurisdictions, such as Ireland, Estonia, and Australia, constitutional amendments originate as bills and become laws in the form of acts of parliament. This may be the case notwithstanding the fact that a special procedure is required to bring an amendment into force. Thus, for example, in Ireland and Australia although amendments are drafted in the form of Acts of Parliament they cannot become law until they have been approved in a referendum. By contrast, in the United States a proposed amendment originates as a special joint resolution of Congress that does not require the President to sign and that the President can not veto.
