Section 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.
