unrepealable
Cannot be undone
Unrepealable describes a law, right, or provision that cannot be revoked or annulled.
The term appears most often in constitutional contexts, where certain protections are declared permanent: The constitution made freedom of speech unrepealable.
In practice, few things are truly unrepealable—the word signals strong intent rather than absolute impossibility.
