What term describes the state of being cancelled or annulled?

The correct term to describe the state of being cancelled or annulled is "revocation." Revocation specifically refers to the act of officially canceling or rescinding a legal or contractual agreement, permission, or privilege. In legal contexts, revocation is a formal action where a previously granted right or agreement is withdrawn, rendering it null and void. This term is commonly used in various legal documents concerning licenses, powers of attorney, and similar instruments where one party can withdraw consent or approval.

While other terms such as termination, abrogation, and invalidation may seem relevant, they each have their own nuances. Termination typically refers to ending a contract or employment relationship but does not imply the same formal legal action as revocation does. Abrogation usually pertains to the repeal or annulment of a law or regulation, emphasizing the legal authority behind the action. Invalidation suggests that something is deemed not valid or without legal force but may not involve a formal revocation process. Thus, "revocation" is the most precise term for indicating a state of cancellation or annulment in legal contexts.
