(a) On application of a party showing an arbitration agreement and the opposing party's refusal to arbitrate, the court shall order the parties to proceed with arbitration. If the opposing party denies the existence of the agreement to arbitrate, the court shall proceed summarily to determine the issue raised and shall order or deny arbitration accordingly.
(b) If an issue referable to arbitration under the alleged agreement is involved in an action or proceeding pending in a court having jurisdiction to hear applications to compel arbitration, the application shall be made therein. Otherwise the application shall be made in the court of proper venue.
(c) Any action or proceeding involving an issue subject to arbitration shall be stayed if an order for arbitration or an application therefor has been made or, if the issue is severable, the stay may be with respect thereto only. When the application is made in such action or proceeding, the order for arbitration shall include such stay.
(d) An order for arbitration shall not be refused on the ground that the claim in issue lacks merit or because any fault or grounds for the claim sought to be arbitrated have not been shown.
