16. Key Takeaways for Practitioners
Disclosure is Mandatory: Section 12(1) imposes continuing duty to disclose all relevant circumstances.
Schedules are Exhaustive: Post-2015 amendment, only Fifth and Seventh Schedule grounds apply.
Timely Challenge Essential: 15-day window from knowledge, or waiver occurs.
Appearance Standard: Justifiable doubts based on objective appearance, not actual bias.
No Relaxation for Party-Appointed: Same independence standards apply to party-appointed arbitrators.
Post-Award Challenge Possible: If ineligibility under Fifth Schedule or non-disclosure.
International Best Practices: IBA Guidelines provide useful reference for disclosure.
Conclusion
Arbitrator independence and impartiality are fundamental to the integrity of arbitral proceedings. The 2015 amendments introduced the Fifth and Seventh Schedules, providing clear, exhaustive grounds for ineligibility and challenge. Arbitrators must make comprehensive disclosures at appointment and throughout proceedings. Parties must exercise due diligence in vetting arbitrators and promptly challenge any conflicts. Proper compliance with Section 12 ensures awards are not vulnerable to challenge under Section 34 and that the arbitration process commands confidence and respect.
