"A clear distinction has always been maintained between negative restrictions upon the right to invoke the jurisdiction of the courts and positive provisions giving efficacy to the award of an arbitrator when made or to some analogous definition or ascertainment of private rights upon which otherwise the Courts might have been required to adjudicate. It has never been the policy of the law to discourage the latter. The former have always been invalid. No contractual provision which attempts to disable a party from resorting to the Courts of law was ever recognised as valid. It is not possible for a contract to create rights and at the same time to deny to the other party in whom they vest the right to invoke the jurisdiction of the courts to enforce them. Parties may agree in the sense of arriving at a common intention as to their future action but, because they do not contemplate legal relations, avoid the creation of rights and thus preclude resort to the courts. Parties may contract with the intention of affecting their legal relations, but yet make the acquisition of rights under the contract dependent upon the arbitrament or discretionary judgment of an ascertained or ascertainable person. Then no cause of action can arise before the exercise by that person of the functions committed to him. There is nothing to enforce; no cause of action accrues. But the contract does not attempt to oust the jurisdiction. What no contract can do is take from a party to whom a right actually accrues, whether ex contractu or otherwise, his power of invoking the jurisdiction of the courts to enforce it. Accordingly a contract providing for arbitration did not, apart from statute, prevent the institution of an action or suit even although an actionable breach of contract was committed by the refusal to refer. But if, before the institution of an action, an award was made, it governed the rights of the parties and precluded them from asserting in the Courts the claims which the award determined. By submitting the claims to arbitration, the parties confer upon the arbitrator an authority conclusively to determine them. That authority enables him to extinguish an original cause of action. His award will do so if it negatives the existence of liability. It will do so if it operates not merely to ascertain the existence and measure of the original liability, but to impose a new obligation as a substitute, whether the obligation results from the tenor of the award or from an antecedent undertaking of the parties to give effect to the determination it embodies. The award given under authority of the parties operates as a satisfaction pursuant to their prior accord of the causes of action awarded upon. ... Any issue might be submitted to arbitration, and upon that issue the award would be as conclusive upon the parties as an award upon the whole cause of action if that had been submitted. What at common law could not be done was to abandon by contract the power of invoking the Court's jurisdiction before the cause of action had been extinguished by an award and the power of countermanding the authority of the arbitrator. But it was never considered that the Court's jurisdiction was ousted by an award, notwithstanding that it concluded the parties with respect to matters which otherwise would be determined by the Court. It is therefore a mistake to suppose that the policy of the law exemplified in the rule against ousting the jurisdiction of the Court prevents parties giving a contractual conclusiveness to a third person's certificate of some matter upon which their rights and obligations may depend ... There are many familiar kinds of contracts containing provisions which make the certificate of some person, or the issue of some document, conclusive of some possible question. The most conspicuous example, perhaps, is the certificate of the engineer or architect under contracts for the execution of works or the construction of buildings."
