§ 12. Non-schedule adjustments. Notwithstanding any other provision of
this chapter, in any case coming within the provisions of sections ten
and eleven of this chapter, in which the right to benefits has been
established and benefits have been paid for not less than three months,
in which the continuance of disability cannot be ascertained with
reasonable certainty, the workmen's compensation board may, in the
interest of justice, approve a non-schedule adjustment agreed to between
the claimant and the political subdivision liable for the payment of
benefits or its insurance carrier. The provisions of subdivision five-b
of section fifteen of the workmen's compensation law shall apply in any
such case.
