Award Void Where Sole Arbitrator Appointed Unilaterally Without Written Waiver of Section 12(5) Ineligibility | Arbitration Act 1996, Sec 12(5) & Sec 34 : Delhi HC

A Delhi High Court set aside a 2022 award, declaring it a nullity because the sole arbitrator had been appointed solely by one party without an express written waiver of the ineligibility bar under Section 12(5) of the Arbitration Act. The ruling makes clear that any such unilateral appointment invalidates the award, affecting parties relying on sole arbitrator clauses.

Section 11 Arbitration Act | Court May Appoint Independent Arbitrator When Contractual Appointing Authority Is Disqualified Under Section 12(5) for Institutional Bias : Punjab & Haryana HC

The Punjab & Haryana High Court affirmed that contractual designation of an arbitrator does not override statutory disqualification under Section 12(5) when the appointing authority has institutional bias. This reinforces that impartiality in arbitration is non-negotiable, and courts must step in to ensure fair proceedings even when parties have pre-agreed appointment mechanisms.
