Ratio in One Line
Ratio: Joint applications by parties under Section 29A of the Arbitration and Conciliation Act, 1996 to extend the arbitrator's mandate constitute waiver by conduct under Section 4 of all non-Section 12(5) objections to the arbitrator's appointment, and a Section 11(6) court cannot review its own appointment order under a self-contained code mandating minimal judicial interference.

How did the case reach the Supreme Court?
Answer: The Patna High Court appointed Justice Shivaji Pandey as sole arbitrator under Section 11(6) on 18 August 2021. Over 70 sittings were held, and parties jointly sought three Section 29A extensions. After final arguments, BRPNNL filed a review application; the High Court recalled its Section 11(6) order on 9 December 2024 and dismissed the petition. Hindustan Construction filed a civil appeal to the Supreme Court under Article 133, which allowed the appeal on 28 November 2025.
| Stage | Forum | Outcome |
|---|---|---|
| Appointment | Patna High Court (Section 11(6), 18 Aug 2021) | Justice Pandey appointed sole arbitrator |
| Extensions | Patna High Court (Section 29A x 3) | Mandate extended twice |
| Review | Patna High Court (9 Dec 2024) | Review allowed; Section 11 order recalled; petition dismissed |
| Civil Appeal | Supreme Court of India | Allowed; HC order set aside; substitute arbitrator directed within two weeks |
What are the facts in brief?
Answer: Hindustan Construction Company and Bihar Rajya Pul Nirman Nigam Limited entered into a bridge-construction contract containing Clause 25 — an arbitration clause vesting exclusive appointment power in BRPNNL's Managing Director. Disputes arose; HCC invoked Section 11. The Patna High Court appointed Justice Shivaji Pandey as sole arbitrator in 2021.
The arbitrator held over 70 sittings. Both parties jointly applied thrice under Section 29A to extend the mandate. After final arguments, BRPNNL filed a review alleging Justice Pandey's subsequent appointment as President of the Meghalaya State Consumer Commission made him statutorily ineligible. The Patna High Court recalled its own Section 11 order and dismissed the petition.
What were the issues before the court?
Answer: The Division Bench framed three principal issues.
- Issue 1: Whether the Patna High Court had jurisdiction to review its own Section 11(6) appointment order?
- Issue 2: Whether Clause 25 — a unilateral appointment clause — renders the arbitration agreement void or only the appointment mechanism severable?
- Issue 3: Whether joint applications under Section 29A constitute waiver of objections under Section 4 of the Arbitration Act?
What did the court hold?
Answer: In Hindustan Construction Company v. BRPNNL, 2025 INSC 1365, the Division Bench allowed the appeal, set aside the High Court's recall and dismissal order, and directed appointment of a substitute arbitrator within two weeks.
- Holding 1: A Section 11(6) court becomes functus officio after appointment; Section 5 bars review of such orders.
- Holding 2: Clause 25's unilateral appointment mechanism is severable under CORE II; the core agreement to arbitrate survives.
- Holding 3: Joint applications under Section 29A constitute waiver of objections by conduct under Section 4 of the Arbitration Act.
- Holding 4: Section 12(5)'s express-written-waiver rule applies only to Seventh-Schedule disqualifications; Section 4 governs all other procedural objections.
- Holding 5: Section 15(2) mandates substitution, not termination, of the arbitral tribunal.
Why is Hindustan Construction v. BRPNNL a landmark?
Answer: The case is a landmark because it harmonises Sections 4, 12(5) and 29A of the Arbitration and Conciliation Act, 1996 and makes joint Section 29A applications dispositive waiver evidence. It stops tactical litigation by public authorities that participate in arbitration for years and then challenge the tribunal after an adverse turn. It also confirms — for the first time in clear terms after CORE II — that Section 11(6) orders are unreviewable and that unilateral clauses are severable rather than wholly void.

Frequently asked questions
What did the Supreme Court decide in Hindustan Construction Company v. BRPNNL?
The Division Bench (Pardiwala & Mahadevan JJ.) on 28 November 2025 (2025 INSC 1365) held that joint applications under Section 29A of the Arbitration and Conciliation Act, 1996 constitute waiver of objections under Section 4 of the Act. A High Court cannot review its own Section 11(6) appointment order (Section 5 bars it). Unilateral appointment clauses are severable under CORE II, preserving the core agreement to arbitrate.
What is the difference between Section 4 and Section 12(5) waiver?
Section 12(5) prohibits waiver of disqualification under the Seventh Schedule unless there is an express written waiver post-dispute. Section 4 governs waiver by conduct of all other procedural objections. The Bench clarified that joint Section 29A applications satisfy Section 4 waiver — even though they do not satisfy the stricter express-written-waiver requirement of Section 12(5).
Why is this case a Section 11 / Section 4 exam staple?
It is the first post-CORE II decision to clearly delineate the two waiver regimes in the Arbitration Act and it confirms that High Courts cannot review Section 11(6) orders. For Judiciary Mains Arbitration papers and CLAT PG current affairs, the interplay of Sections 4, 11(6), 12(5), 15(2) and 29A is directly testable.
What happens to ongoing arbitration when the arbitrator becomes ineligible?
Section 15(2) of the Arbitration Act mandates substitution, not termination. The Bench held that the High Court erred by dismissing the petition instead of substituting the arbitrator. Proceedings continue from where they were suspended before the substitute arbitrator, preserving evidence already recorded and orders already passed.
Are unilateral appointment clauses entirely void after CORE II?
No. They are severable. The core intention to arbitrate survives, and the defective appointment mechanism is severed. The Section 11(6) court then appoints or substitutes the arbitrator. The Bench in Hindustan Construction applied this principle directly, preserving the arbitration agreement in Clause 25 of the HCC-BRPNNL contract despite its unilateral appointment mechanism.
