The reason of the law ceasing, the law itself ceases.

Explanation

A statute enacted to address a specific evil or condition becomes void in its application when that evil or condition no longer exists.

Where this applies

• A wartime regulation is still being enforced decades after the war ended.
• A law passed to address a temporary crisis is still on the books long after the crisis is over.
