ORDER : 1. On the facts of this case, we are not inclined to interfere with the order passed by the High Court allowing the application of the respondent under Section 11 of the Arbitration Act and appointing the Arbitrator. 2.

The Arbitrator, naturally, shall decide such an issue on merits. 3. The Special leave Petition is dismissed. 4. Interlocutory Application(s) pending, if any, stands disposed of accordingly.
