§ 7501. Effect of arbitration agreement. A written agreement to submit any controversy thereafter arising or any existing controversy to arbitration is enforceable without regard to the justiciable character of the controversy and confers jurisdiction on the courts of the state to enforce it and to enter judgment on an award. In determining any matter arising under this article, the court shall not consider whether the claim with respect to which arbitration is sought is tenable, or otherwise pass upon the merits of the dispute.
