Section 189-B. Changing number of trustees

Any incorporated church or
  society to which this article is applicable may, at an annual  corporate
  meeting,  change  the number of its trustees to any number from three to
  twelve and classify them so that the terms of  one-third  as  nearly  as
  possible  expire each year, provided that notice of such intended change
  be included in the notice of such  annual  corporate  meeting.  No  such
  change shall affect the terms of the trustees then in office, and if the
  change  reduces  the  number  of trustees, election shall not be held to
  fill the vacancies caused by the expiration of the  terms  of  trustees,
  until  the  number  of  trustees equals the number to which the trustees
  were reduced. Whenever the number of trustees in office is less than the
  number so determined on, sufficient additional trustees shall be elected
  to make the number of trustees for the ensuing year equal to the  number
  so  determined on. The trustees so elected up to and including as nearly
  as possible one-third of the number so determined on, shall  be  elected
  for three years, the remainder up to and including as nearly as possible
  one-third of the number so determined on for two years and the remainder
  for one year.
