Section 113. Creation or modification of local retirement systems prohibited

a. No municipality, after April twelfth,  nineteen  hundred
  twenty-two,  shall  create  any  retirement  system  for its officers or
  employees.
    b. Notwithstanding any inconsistent provisions of any general, special
  or local law, ordinance or city  or  village  charter,  no  municipality
  shall  have power to add, change, modify, supersede, amend or repeal any
  provision relating to contributions payable to or  pensions,  annuities,
  or  other  benefits  payable by any pension or retirement system or fund
  administered by such municipality or an agency thereof for  the  benefit
  of officers or employees of such municipality, except as provided herein
  or  in  article  four or article six of this chapter. Any such provision
  for the payment of a pension or retirement allowance of a fixed  amount,
  expressed  in  dollars,  may  be  amended by the municipality to provide
  future retirees with a pension or retirement allowance  in  terms  of  a
  percentage,  not  to  exceed fifty per cent, of the annual salary before
  retirement of the officer or employee.
    c. The provisions of subdivision b of this section shall not prevent a
  municipality having the power to adopt local laws to  provide  by  local
  law,  or  a  municipality  not  having  the power to adopt local laws to
  provide by ordinance  or  resolution,  for  increased-take-home-pay  for
  members  of a pension or retirement system or fund administered by it or
  by any agency thereof. Such local  law,  ordinance,  or  resolution  may
  provide   a   plan   for  increased-take-home-pay  which  shall  not  be
  inconsistent with the provisions, limitations, restrictions and  payroll
  periods of the plans for increased-take-home-pay provided by chapters of
  the  laws  of  nineteen  hundred  sixty,  entitled  "An act to amend the
  retirement and social security law,  in  relation  to  the  addition  of
  pensions   providing-for-increased-take-home-pay,  death  benefits,  and
  reopening of a plan for retirement at age fifty-five", "An act to  amend
  the  retirement  and social security law, in relation to authorizing the
  provision of  added  pensions-providing-for-increased-take-home-pay  and
  death  benefits for officers and employees of participating employers in
  the New York state employees' retirement system", "An act to  amend  the
  mental  hygiene law, in relation to reducing contributions of members of
  the New York state hospital system and providing added death  benefits,"
  and any acts amendatory thereof.
