That in the event the qualified employees of the city shall elect to be covered under provisions of the Old Age and Survivor Insurance System as embodied in the Social Security Act of the United States the city clerk shall deduct from such employee’s salary the amount of the employee’s tax which is imposed by the Federal Insurance Contribution Act and the amount deducted from such wages shall be paid to the O.A.S.I. Contribution Fund in partial discharge of the liability of the city. Failure to deduct such contribution shall not relieve the employee or employer of liability therefor. The city shall, out of the funds appropriated as heretofore set forth, also forward to the Governor of the state or Govenor’s duly authorized agent such sums as the city shall be required to contribute under provisions of the Social Security Act of the United States and all costs allocable to the administration of this fund. (Prior code § 1.44.070.)
