To this end an arbitrator shall have the power to allow all necessary amendments to the grievance and the power to waive formal procedural irregularities in the processing of a grievance in order to determine the real matter in dispute and to render a decision according to equitable principles and the justice of the case. ii. The arbitrator shall not have jurisdiction to alter or change the provisions of the Collective Agreement or to substitute new ones. iii. The provisions of this article do not override the provisions of the B.C.
