A bureaucrat can remove their own rights, but in order for you to remove a different bureaucrat's rights, you do have to contact Wikia.

Whether it's approved seems to be up to who answers the request. One time, I was told that they usually don't remove bureaucrat rights, even though that person had been gone for over five years. Another time, they did not have any problem with the request and removed those rights.
