Section 189-C. Meetings of trustees

The chairman of the board of trustees
  of  any  incorporated  church  or  society  to  which  this  article  is
  applicable  or  any two members of such board may call a meeting of such
  trustees  by  giving  at  least  twenty-four  hours'   notice   thereof,
  personally  or  by mail, to all the other trustees, but by the unanimous
  consent of the trustees a meeting may be held  without  previous  notice
  thereof. A majority of the trustees lawfully convened shall constitute a
  quorum  for  the  transaction of business.  In case of a tie vote at the
  meeting of the trustees the presiding officer  of  such  meeting  shall,
  notwithstanding  he  had voted once, have an additional casting vote. In
  case of a vacancy in the office of trustee the  remaining  trustees  may
  fill  such  vacancy  until  the  next  annual corporate meeting when the
  vacancy shall be filled for the unexpired term.
