"Where a matter is within the scope of an arbitration, I would unhesitatingly give effect to the foregoing consideration and exclude the availability of the inherent power of the Supreme Court or the power expressly elaborated by s. 23 of the Supreme Court Act. But I find unacceptable the proposition that the Court is incapable of providing relief, and has lost its powers altogether, simply because parties have entered into a private contract by which they have submitted a dispute to arbitration. The proposition may be tested this way. Imagine that a government and a private company for their own purposes agreed to private arbitration and further agreed that information of profound importance to the community and of legitimate public interest were to be suppressed from public access. Can it seriously be suggested that their private agreement can, endorsed by a procedural direction of an arbitration, exclude from the public domain matters of legitimate public concern? It is no answer to this question to state that, in the present case, the arbitrator reserved powers of exempting the Commonwealth and liberty to apply for variation in his orders for that purpose. In issue here is the scope of the arbitration itself and the ambit of the orders that may properly be made by an arbitrator within that scope. Allowing that a large circle will be drawn within which the arbitrator may make procedural orders, the circle is not without limit. A point will be reached where the edge of the circle will be arrived at and passed. When passed, the Court, upholding the other interests which lie outside the legitimate scope of the arbitration, will retain its powers to intervene. To deny those powers is to accord too great a right to the parties or the arbitrator to define the limits of the commercial arbitration which the Act protects from external curial intervention. The power to define the boundaries and to prevent directions which go beyond them, remains in the Court. Any other view permits the parties and the arbitrator to define, without limitation, the territory which they occupy pursuant to their private agreement. That cannot be. The rule of law requires that the Court, protective of other competing public and private interests, will define and, where necessary and appropriate, declare the limits beyond which the purported powers in pursuit of private arbitration intrude into competition with other legitimate public and private rights and duties."
