Any member of a Planning Commission, once qualified and appointed, may be removed from office, for malfeasance, misfeasance or nonfeasance in office or for other just cause, by a majority vote of the Board, taken after the member has received 15 days' advance notice of the intent to take such a vote. A hearing shall be held in connection with the vote if the member shall request it in writing. Any appointment to fill a vacancy created by removal shall be only for the unexpired term.
