is ineligible to be appointed as an arbitrator, still go ahead and say that they have full faith and confidence in him to continue as such. The facts of the present case disclose no such express agreement. The appointment letter which is relied upon by the High Court as indicating an express agreement on the facts of the case is dated 171-2017. On this date, the Managing Director of the appellant was certainly not aware that Shri Khan could not be appointed by him as Section 12(5) read with the Seventh Schedule only went to the invalidity of the appointment of the Managing Director himself as an arbitrator. Shri Khan's invalid appointment only became clear after the declaration of the law by the Supreme Court in TRF Ltd. v. Energo Engg. Projects Ltd., (2017) 8 SCC 377 , which, as we have seen hereinabove, was only on 3-7-2017. After this date, far from there being an express agreement between the parties as to the validity of Shri Khan's appointment, the appellant filed an application on 7-10-2017 before the sole arbitrator, bringing the arbitrator's attention to the judgment in TRF Ltd. v. Energo Engg. Projects Ltd., (2017) 8 SCC 377 and asking him to declare that he has become de jure incapable of acting as an arbitrator. Equally, the fact that a statement of claim may have been filed before the arbitrator, would not mean that there is an express agreement in words which would make it clear that both parties wish Shri Khan to continue as arbitrator despite being ineligible to act as such. This being the case, the impugned judgment is not correct when it applies Section 4, Section 7, Section 12(4), Section 13(2) and Section 16(2) of the Act to the facts of the present case, and goes on to state that the appellant cannot be allowed to raise the issue of eligibility of an arbitrator, having itself appointed the arbitrator. The judgment under appeal is also incorrect in stating that there is an express waiver in writing from the fact that an appointment letter has been issued by the appellant, and a statement of claim has been filed by the respondent before the arbitrator. The moment the appellant came to know that Shri Khan's appointment itself would be invalid, it filed an application before the sole arbitrator for termination of his mandate. ”
