Removals of Commissioners (including the Mayor) and members of boards or commissions created by this charter by the Commission shall be made for either of the following reasons: (1) for any reason specified by statute for removal of city officers by the Governor, (2) for any act declared by this charter to constitute misconduct in office. Such removals by the commission shall be made only after hearing of which such officer has been given notice by the Clerk at least ten days in advance either personally or by delivering the same at his last known place of residence. Such notice shall include a copy of the charges against such officer. The hearing shall afford an opportunity to the officer, in person or by attorney, to be heard in his defense, to cross-examine witnesses and to present testimony. If such officer shall neglect to appear at such hearing and answer such charges, his failure to do so may be deemed cause for his removal. A majority vote of the members of the Commission in office at the time, exclusive of any member whose removal is being considered, shall be required for any such removal.
