In fact, the court finds it surprising that the respondent, which is a government company, is so vehemently opposing an application for extension of the mandate of the learned Arbitral Tribunal, particularly when, on 22 May 2023, the respondent has itself appointed a substitute arbitrator in place of its original arbitrator, who unfortunately expired in the interregnum. The plea of acquiescence, therefore, if any, if at all, would operate against the respondent rather than against the petitioner. By nominating a substitute arbitrator on 22 May 2023 and having failed to challenge any of the orders passed by the learned Arbitral Tribunal prior thereto, which granted liberty to the parties to revive the proceedings at an appropriate stage, the respondent can certainly not be heard to oppose the petitioner's application under Section 29A(4), which has been filed consequent on the specific liberty to that effect granted by the learned Arbitral Tribunal in its order dated 5 July 2023, which, too, I may note, has remained unchallenged.
