Section 60. Town board constituted

1. In every town the supervisor and the
  town councilmen shall constitute the town board and shall be vested with
  all the powers of such a town and shall possess  and  exercise  all  the
  powers  and be subject to all the duties now or hereafter imposed by law
  upon town boards and town boards of health within such towns; but it  is
  not  intended  to extend the power of said boards or officers within the
  limits of any incorporated village or city, or in any manner to  abridge
  or  interfere  with  the power and authority of the officers of any such
  village or  city  within  its  corporate  limits,  except  as  otherwise
  provided by law.
    2.  In any town in which a town justice serves as a member of the town
  board, such town justice shall continue to serve as a member of the town
  board until the expiration of his  term.  Thereafter  any  town  justice
  shall  not  be a member of the town board and a town councilman shall be
  elected as a member of such town board in place  of  such  town  justice
  except  as  otherwise  provided  by the town board by resolution adopted
  pursuant to the provisions of section sixty-a of this chapter.
