9. Power to party to appoint new arbitrator or in certain cases, a sole arbitrator. -Where an arbitration agreement provides that a reference shall be to two arbitrators, one to be appointed by each party, then, unless a different intention is expressed in the agreement,-

(a) if either of the appointed arbitrators neglects or refuses to act, or is incapable of acting, or dies, the party who appointed him may appoint a new arbitrator in his place;

(b) if one party fails to appoint an arbitrator, either originally or by way of substitution as aforesaid, for fifteen clear days after the service by the other party of a notice in writing to make the appointment, such other party having appointed his arbitrator before giving the notice, the party who has appointed an arbitrator may appoint that arbitrator to act as sole arbitrator in the reference, and his award shall be binding on both parties as if he had been appointed by consent:

Provided that the Court may set aside any appointment as sole arbitrator made under clause (b) and either, on sufficient cause being shown, allow further time to the defaulting party to appoint an arbitrator or pass such other order as it thinks fit.

Explanation.-The fact that an arbitrator or umpire, after a request by either party to enter on and proceed with the reference, does not within one month comply with the request may constitute a neglect or refusal to act within the meaning of section 8 and this section.
