A more thorough explanation:

A repealing clause is a part of a law that cancels or revokes a previous law. It is a statutory provision that repeals an earlier statute.

For example, if there is a law that says it is illegal to sell alcohol on Sundays, but a new law is passed that allows alcohol sales on Sundays, the new law will have a repealing clause that cancels the old law.

Another example is the Affordable Care Act, which included a repealing clause that cancelled certain provisions of previous healthcare laws.

These examples illustrate how a repealing clause is used to remove or replace outdated or ineffective laws with new ones.
