Which term describes the action of officially revoking a COF?

The action of officially revoking a Certificate of Fitness (COF) is best described by the term "revocation." This term is used in regulatory contexts to indicate that a previously granted certification or permission is being withdrawn by an authority due to certain criteria not being met or changes in compliance status.

Revocation signifies a formal decision that nullifies the COF, meaning the individual or entity is no longer authorized to operate under the terms granted by that certificate. This process may occur for various reasons, such as failure to adhere to safety regulations, lack of qualifications, or any situation that violates the conditions under which the COF was initially issued.

In contrast, while suspension might imply a temporary halt to the validity of the COF, it does not necessarily indicate a permanent termination of the license as revocation does. Cancellation may suggest that the application process has been halted or the certificate is considered void but does not carry the same formal connotation of withdrawing a granted right. Termination often refers to the ending of a contract or agreement rather than the specific action of nullifying a certificate of fitness. Thus, revocation is the precise term that encapsulates the action of taking away a COF officially.
