Case Note & Summary
The Supreme Court of India, in a Constitution Bench judgment, addressed the validity of unilateral appointment of arbitrators under the Arbitration and Conciliation Act, 1996. The background involved multiple appeals where arbitration clauses gave one party, often a public sector entity, the exclusive power to appoint arbitrators. The core legal issue was whether such unilateral appointment clauses violate the mandatory principle of equality under Section 18 of the Act, which requires equal treatment of parties in the appointment process. The Court held that party autonomy is subject to the fundamental principles of independence, impartiality, and equality. Unilateral appointment clauses create an inherent bias and violate the nemo judex in causa sua rule. The Court further held that in public-private contracts, such clauses are unconscionable under Section 23 of the Indian Contract Act, 1872, as they are opposed to public policy. The decision was made prospective, meaning past appointments remain valid, but future arbitration agreements must ensure equal participation in the appointment process. The Court directed that any clause allowing unilateral appointment is void, and the appropriate court under Section 11(6) must appoint arbitrators in such cases.
Headnote
A) Arbitration Law - Appointment of Arbitrators - Unilateral Appointment - Section 18, Section 12(5), Seventh Schedule, Arbitration and Conciliation Act, 1996 - The principle of equality under Section 18 mandates that no party has a unilateral right to appoint an arbitrator; any clause giving one party exclusive power to appoint is void as it violates equality and impartiality. (Paras 48-83) B) Arbitration Law - Independence and Impartiality - Nemo Judex Rule - Doctrine of Bias - Sections 12, 18, Arbitration and Conciliation Act, 1996 - The nemo judex in causa sua rule applies to arbitrators; a person cannot be a judge in their own cause. Unilateral appointment creates a real likelihood of bias, disqualifying the arbitrator. (Paras 53-83) C) Contract Law - Unconscionability - Public-Private Contracts - Section 23, Indian Contract Act, 1872 - Arbitration clauses in public-private contracts that allow the public entity to unilaterally appoint arbitrators are unconscionable and opposed to public policy, rendering them void. (Paras 90-106) D) Arbitration Law - Prospective Overruling - Validity of Past Appointments - The judgment applies prospectively; appointments made prior to this judgment are not invalidated, but future appointments must comply with the equality principle. (Paras 109-110)
Issue of Consideration
Whether the principle of equality under Section 18 of the Arbitration and Conciliation Act, 1996 prohibits unilateral appointment of arbitrators, and whether such clauses in public-private contracts are unconscionable and void.
Final Decision
The Supreme Court held that unilateral appointment of arbitrators violates the mandatory principle of equality under Section 18 of the Arbitration and Conciliation Act, 1996. Such clauses are void and unenforceable. The judgment applies prospectively, so past appointments remain valid. Future arbitration agreements must ensure equal participation in the appointment process; otherwise, the court under Section 11(6) will appoint arbitrators.
