A congregation of the Jewish faith may at any general or special corporate meeting thereof change the number of its trustees to not more than seventy-two and classify them so that the terms of one-third shall expire each year and the trustees elected shall hold office for three years. Whenever the number of trustees in office is less than the number determined on, sufficient additional trustees shall be elected to make the total number of trustees equal to the number determined on. The additional trustees so to be elected shall be classified and hold office for such terms, not exceeding three years each, so that the terms of one-third of the total number of trustees shall expire each year, and thereafter for a term of three years each. The right of the members of such congregation to vote at meetings thereof shall be fixed by its by-laws, but every member of such congregation entitled to vote at any meeting thereof may vote by proxy on any proposition to sell, mortgage or lease any of its property or for its consolidation with one or more other religious corporations of the Jewish faith, or, in a city having a population of one million or more according to the latest federal census, in any election of trustees or officers. Every proxy must be executed in writing by the member conferring the same and shall not be given to any person other than a member of the congregation. No proxy shall be valid after the expiration of one year from the date of its execution. Every proxy shall be revocable at the pleasure of the person executing it.
