Section 58 — Period of operation of settlements and awards.

58(4)

Where the appropriate Government, whether of its own motion or on the application of any party bound by the award, considers that since the award was made, there has been a material change in the circumstances on which it was based, the appropriate Government may refer the award or part of it to the Tribunal, if the award is made by the Tribunal for decision whether the period of operation should not, by reason of such change, be shortened and the decision of the Tribunal on such reference shall be final.
