The President pro tem, during this absence or disability, shall perform the duties and possess all the rights and powers of the President but shall not be entitled to vote both as President pro tem and as a Trustee.
(B) In the absence of the President, or President pro tem, the corporate authorities may elect one of their members to act as a temporary Chairperson. The temporary Chairperson shall have only the powers of a presiding officer and a right to vote only in the capacity as Trustee on any ordinance, resolution or motion.
