27 - Continuity of local governments.

§ 27. Continuity  of  local governments. 1. Every county, except those
  wholly contained within a city, every city, every town and every village
  shall have power to  provide  by  local  law,  and  every  other  public
  corporation,  district  corporation  or public benefit corporation shall
  have power to provide by resolution, for its continuity and that of  its
  elective  and  appointive officers, including members of its legislative
  or governing body when, in the event of a  disaster  and  the  emergency
  conditions  caused  thereby, any of such officers is unable to discharge
  the powers and duties of his office or  is  absent  from  the  political
  subdivision.  In any such local law or resolution, provision may be made
  that the removal of a disability or the termination of an  absence  from
  the  political  subdivision  of  an officer higher on a list or order of
  succession provided therein to an office shall not terminate the service
  in such office  of  an  individual  lower  on  such  list  or  order  of
  succession  who  is temporarily filling such office. Notwithstanding the
  provisions of any general or special law or city or village  charter,  a
  local  law  or  resolution  adopted pursuant to this section may be made
  effective without approval at a mandatory or permissive  referendum  but
  in no case shall such local law or resolution become effective until one
  certified  copy  thereof  has been filed with the clerk of the political
  subdivision or other appropriate official designated for such purpose by
  the respective legislative or governing body, one certified copy thereof
  has been filed  in  the  office  of  the  state  comptroller  and  three
  certified  copies thereof have been filed in the office of the secretary
  of state.
    No provision of this subdivision shall be construed or interpreted  as
  affecting the validity of any ordinance, local law or resolution enacted
  prior  to  April  first,  nineteen hundred seventy-nine or actions taken
  thereunder by the government of any county, city, town or village.
    2. The provisions of this section shall not be applicable in any  case
  where  the  continuity  of  the government of a political subdivision or
  that of any of its elective or appointive officers is otherwise provided
  for by or pursuant to law.
    3. This section  shall  be  construed  liberally.  The  powers  herein
  granted  shall  be  in  addition to and not in substitution of any power
  granted, procedure provided or provision made in any other law.
