Final answer:
The authority that can revoke an award is usually the governing body or committee of the organization that issued it, based on their respective rules and bylaws.
Step-by-step explanation:
The authority able to revoke an award once it has been presented typically depends on the rules and bylaws of the organization or entity that issued the award. In most cases, a governing body, board, or committee associated with the award's issuance has the power to rescind it. This usually happens if the recipient is found to have violated the terms of the award, if there has been an error in awarding it, or if the recipient's actions are later discovered to compromise the integrity of the award.
For instance, in the case of academic awards, it might be the educational institution or the academic department that has the authority to revoke the award. In other contexts, such as professional awards or honors, it could be the specific professional organization or even a governmental authority, depending on the nature of the award.
