Short answer: A clause giving one disputing party exclusive control over appointing the sole arbitrator raises serious impartiality and equal-treatment concerns under Indian arbitration law. The Supreme Court Constitution Bench decision in Central Organisation for Railway Electrification v. ECI SPIC SMO MCML (JV), or CORE II, held unilateral appointment of a sole arbitrator impermissible and addressed one-sided panel selection. But the result depends on the clause, tribunal, timing, waiver and procedural history. A defective appointment procedure does not necessarily erase the underlying arbitration agreement.
This is an issue-spotting guide, not an opinion on any specific contract.
What does a one-sided appointment clause look like?
Examples include a contract allowing one party to appoint the sole arbitrator, letting a managing director choose the decision-maker, or allowing one party to create a panel from which the other side must select. A government department or public-sector entity may also dominate the panel process.
The concern is not that an arbitrator is automatically biased because of professional history. The issue is whether the process gives one side unequal influence or permits a person who is legally ineligible to act. Independence, impartiality, disclosure and equality in appointment are related but distinct questions.
| Clause pattern | Main question | Avoid assuming |
|---|---|---|
| One party appoints a sole arbitrator | Is exclusive choice incompatible with neutrality and equality? | That the whole arbitration agreement is void |
| One side proposes a panel, other chooses | Was the panel formed by a fair process? | That choosing one name always cures imbalance |
| Named official is ineligible | Do section 12(5) and Seventh Schedule apply? | Delegating the choice cures ineligibility |
| Parties agree on a neutral process | Was it validly agreed and followed? | “Mutual” resolves every conflict concern |
What did the Supreme Court decide in CORE II?
The Constitution Bench judgment dated 8 November 2024 considered equality and neutrality in appointments under arbitration clauses, including public-private contracts. It held that unilateral appointment of a sole arbitrator by an interested party is impermissible and examined party-controlled panel procedures. Its reasoning addresses section 18’s equal-treatment requirement with the Act’s independence and impartiality provisions.
Paragraph 168's prospective direction is expressly limited to appointments in three-member tribunals made after 8 November 2024. The judgment separately explains that TRF and Perkins had already governed sole-arbitrator situations; do not extend the prospective protection for three-member panels to every unilateral sole-arbitrator appointment. For a three-member tribunal, compare the appointment date with the judgment date and examine whether a party was compelled to choose from a curated panel. For a sole arbitrator, analyze the clause under the Court's holdings and the earlier authorities, rather than treating paragraph 168 as a universal date-based shield. The judgment's majority also differs from the separate opinions, so identify which opinion supports the proposition you plan to cite. This distinction can change the analysis of a legacy clause and should be checked against the exact paragraph, tribunal structure and later procedural orders.
Read the official CORE II judgment in full. The Arbitration and Conciliation Act, 1996 is the primary statute. Review sections 11, 12, 13, 18 and 34 and the Fifth and Seventh Schedules.
Does an invalid appointment clause end arbitration?
Not necessarily. Supreme Court decisions distinguish the existence of an arbitration agreement from the validity of a particular appointment procedure. The procedure may be severable, letting the agreement survive while a neutral is appointed under section 11 or another lawful mechanism.
A 28 November 2025 Supreme Court judgment in Hindustan Construction Company Ltd. v. Bihar Rajya Pul Nirman Nigam Limited, 2025 INSC 1365, reiterated the distinction and discussed severability and waiver in its factual setting. It applied CORE II while assessing a section 11 request concerning an appointment mechanism. Read the official 2025 judgment and compare the clause and procedural history before drawing an analogy.
The practical question may be whether arbitration can continue with a validly appointed neutral or whether another clause makes the promise unworkable. The answer can turn on wording, failure provisions, separability and requested relief.
How do section 12(5) and the Seventh Schedule work?
Section 12(5) says that, notwithstanding prior agreement, a person whose relationship with the parties, counsel or subject matter falls within the Seventh Schedule is ineligible to be appointed. Its proviso allows waiver by express written agreement after disputes have arisen.
That is a specific waiver. A pre-dispute contract clause should not automatically be treated as satisfying the post-dispute requirement. Silence is not a written waiver. Keep any later consent and assess whether it expressly addresses the ineligibility.
Section 12 also requires disclosures and covers circumstances that may create justifiable doubts about independence or impartiality. The Fifth Schedule guides potential doubts; the Seventh Schedule lists relationships creating ineligibility. Do not describe every conflict as a Seventh Schedule disqualification.
What should you do after an appointment notice?
Act promptly and preserve the sequence. The Act has challenge procedures and time limits, and participation without a timely objection may affect options. State the precise concern: appointment power, section 12(5) relationship, missing disclosure or failure to follow the agreed procedure. Avoid unsupported accusations.
Gather the signed contract and incorporated terms; arbitration invocation and appointment notices; disclosures; proof of receipt; appointing person’s identity and role; tribunal composition; dates the dispute arose and appointment occurred; post-dispute waiver; objections and participation; current orders and hearing dates. Confirm whether the arbitration is domestic or international and which court has jurisdiction.
The route differs by issue. Section 13 provides a challenge procedure before the tribunal. Section 14 addresses termination of mandate in stated circumstances. Section 11 concerns court appointment when an agreed procedure fails. Section 34 provides limited grounds to set aside an award. Do not assume that you can skip the tribunal process or wait until an award without advice.
Worked example: a supply contract names the buyer’s director
A fictional supply agreement says the buyer’s managing director will be sole arbitrator. A payment dispute arises and the director sends an appointment letter. The supplier preserves the clause, notice and appointment date, then checks the director’s role, section 12(5), CORE II and procedural history.
The supplier should not conclude that the entire contract is void or that the director has already acted unfairly. Counsel can assess whether appointment is impermissible, whether a post-dispute waiver exists, and what prompt application is available. The arbitration agreement may survive even if the selection method is challenged. The facts here are invented and illustrate issue-spotting, not an actual dispute or a guaranteed outcome.
Build a date-and-procedure record before seeking relief
Create a one-page chronology with the contract date, dispute date, invocation date, appointment date, disclosure date, first hearing, objection and any written consent after the dispute. Attach the exact clause and identify whether it calls for one arbitrator or three. Record who curated any panel, who could choose from it, whether each party had equal nomination rights, and whether the appointing authority had a relationship listed in the statute. Distinguish facts from legal conclusions: “the director signed the appointment letter” is a fact; “the director is disqualified” requires statutory analysis.
Then identify the procedural route with counsel. A section 13 challenge is ordinarily raised before the tribunal under the Act's procedure; a section 14 application may be relevant to de jure or de facto inability; and section 11 may become relevant if the agreed appointment procedure fails. A request should explain why that path fits the clause and procedural stage. Preserve proof of service and do not stop participating or miss a hearing based only on an objection letter. Parallel court applications, waiver arguments and the effect of an appointment already made depend on the record and applicable precedent.
How should you verify current law?
Arbitration doctrine has evolved through larger-bench decisions. Identify the exact proposition, read the controlling judgment, confirm the prospective direction and trace later cases. Gotham’s guides to finding binding precedent in India and judgment treatment research explain the workflow. Use the citation verification checklist to confirm that a proposition appears in the judgment itself.
Counsel should also verify seat, institutional rules, contract amendments, limitation, court jurisdiction and procedural stage. Track dates with source documents as described in the legal deadline workflow. Gotham’s India legal research overview describes source-based research support. Contact Gotham or visit the home page for workflow discussion. Research tools organize authorities; counsel advises on a live challenge.
Frequently asked questions
Can a company director appoint the sole arbitrator?
An interested party’s exclusive appointment power raises a substantial objection after CORE II. Whether the specific appointment can stand depends on clause, parties, timing, tribunal and procedural posture. Read the full judgment and Act.
Does CORE II apply to appointments made before 8 November 2024?
Paragraph 168 states prospective application for appointments in three-member tribunals made after 8 November 2024. The Court discusses sole-arbitrator cases separately, noting that TRF and Perkins had already held the field. For a particular dispute, verify tribunal type, appointment date, challenge history and later decisions rather than applying the direction to all appointment patterns.
Can parties waive section 12(5) before a dispute?
The proviso contemplates an express written waiver after disputes arise. Do not assume an earlier contract clause satisfies that requirement. Check the actual writing and statutory context.
If the appointment route is invalid, is arbitration over?
Not automatically. The arbitration agreement and the selection procedure can be distinct. Section 11 may permit court appointment depending on the agreement and facts. A clause conditioning all arbitration on the invalid mechanism raises further questions.
Should I wait until the award to object?
Do not assume that waiting is safe. The Act provides challenge procedures and timelines, and participation can matter. Get prompt advice on forum and deadline.
Is a former employee always disqualified?
No categorical answer follows from that label alone. Review section 12, schedules, current and past relationships, clause, precedent and waiver. The statutory analysis is not simply whether the person once worked for a party.
Practical takeaway
Examine the exact appointment clause, applicable law, CORE II’s prospective direction, section 12(5) and procedural record. Ask whether a neutral can replace the appointment while preserving the arbitration agreement. Avoid conclusions from snippets or broad generalizations.
This article provides general legal information, not legal advice. Appointment validity depends on the arbitration clause, parties, timing, waiver and procedural posture. Obtain advice from arbitration counsel promptly.
