Club Penguin Wiki: Admin Authority

Administrators have the final say over everything that occurs in the wiki. An administrator may delete a certain page or override a certain project, if they have a valid reason. If they do not include one, ask them. Do not start arguing and complaining... instead calmly state your point to the admin who deleted it, and discuss it with them.

Admins Veto
Administrators may veto any particular community vote as long as they have a valid reason. However, the administrators may not change the results of harmless votes such as Penguin of the Month, Featured Article, and Featured Image unless content violating the policy is displayed.

At least "4" administrators must veto a certain vote to prevent it from passing.
