Yes. It is perfectly acceptable its up to the elected members to select the individual they think is best suited to chair each committee (sometimes that means an individual having multiple hats). Personally I think it is healthy to encourage others to step forward and spread the workload out mind but really depends on people available (size of council and willing/able people). Certainly no point putting people in position who incapable of chairing meeting (or little interest in committee itself) just simply dumped on it because they need someone to chair it and rest on it chairs of the other three. Historically I gather the Council has always avoided Finance Chair been the Chair of Council (feeling is the separation of roles is healthy) but gather nothing preventing it should majority want that.
