What is the definition of "revoke" in a legal context?

In a legal context, "revoke" means to cancel or rescind an authority or decision that was previously granted. This action implies that a particular legal power, agreement, or document is no longer valid or applicable. For example, a notary public may revoke a notarized document if it was executed under circumstances that render it void, such as fraud or misrepresentation.

This understanding of revocation is crucial in legal proceedings or when managing official documents, as it indicates the removal of legal standing or effectiveness of that document or authority. In contrast, the other definitions involve actions that increase or affirm a status or authority, which is fundamentally different from the act of revoking.
