Who can remove a Cubmaster?

[ChuckConnors 10]

I'm trying to get an understanding of how a Cubmaster is removed from position. I've heard it must be agreed by the COR and Committee Chair. The question arises whether it is the Committee Chair alone or must it be decided by a majority vote of the Pack Committee? Since the COR is considered part of the Pack Committee, does the COR get another vote as part of the committee in addition to his own individual vote as COR? Thanks in advance.
