Disqualification of Arbitrator: Does Shareholding Trigger Bias?
A recent Supreme Court judgment has reignited the debate on the disqualification of an arbitrator under the Arbitration and Conciliation Act, 1996. Specifically, the Court examined whether an arbitrator’s shareholding in one of the disputing parties automatically leads to disqualification.
Importantly, the Court clarified that mere shareholding without material influence or actual bias does not automatically trigger disqualification under Section 12(5) read with the Seventh Schedule. Therefore, this ruling provides a balanced and practical framework for arbitration in India.

Shareholding and Conflict of Interest : Legal Position
Private vs Public Company Distinction
The Court drew a clear distinction between private and public companies:
- Private Companies (Entry 17):
Even minimal shareholding may result in disqualification. This is because ownership is concentrated, and even a small stake can imply control. - Public Companies (Entry 32):
However, disqualification depends on materiality. In other words, only substantial shareholding that creates a real financial interest will attract disqualification.
Thus, minor or portfolio investments such as mutual fund holdings do not automatically disqualify an arbitrator.
Objective Test for Disqualification of Arbitrator

The Court emphasised an objective test. In simple terms, the key question is:
Would a fair-minded and informed observer perceive a real possibility of bias?
Accordingly, the Court rejected a blanket rule that any shareholding leads to disqualification. Instead, it focused on whether the interest is significant enough to influence the arbitrator’s decision.
Section 12(5) vs Section 12(3) : Key Difference
- Section 12(5):
Provides automatic (de jure) disqualification in cases listed under the Seventh Schedule. - Section 12(3):
Applies where there are justifiable doubts about independence or impartiality.
Therefore, not every shareholding falls under mandatory disqualification. Instead, only material conflicts qualify.
Disclosure Obligations and Practical Guidelines
Mandatory Disclosure by Arbitrators
Arbitrators must disclose:
- Direct and indirect shareholding
- Nature of investment (personal or portfolio)
- Value and percentage of shares
- Any advisory or board relationships
Moreover, upfront disclosure ensures transparency and builds trust in the arbitral process.
Strategy for Challenging Arbitrators
Parties should:
- Provide evidence of materiality (not assumptions)
- Rely on financial disclosures and SEBI filings
- Avoid vague allegations of bias
Consequently, evidence-based challenges are more likely to succeed.
Alignment with Previous Supreme Court Judgments
This ruling aligns with earlier decisions such as:
- HRD Corporation v. GAIL (2018) – Mandatory disqualification under Seventh Schedule
- Perkins Eastman v. HSCC – Ineligibility of interested arbitrators
However, the present judgment introduces a balanced approach, preventing misuse of minor disclosures.
Impact on Arbitration Practice in India
This decision strengthens India’s arbitration framework. On the one hand, it protects impartiality. On the other hand, it prevents unnecessary disqualification of arbitrators with minor investments.
Furthermore, it aligns with international standards like the IBA Guidelines on Conflicts of Interest. As a result, India continues to promote arbitration-friendly reforms.
Conclusion: Disqualification of Arbitrator Depends on Materiality, Not Mere Shareholding
In conclusion, the disqualification of an arbitrator due to shareholding depends on materiality and real likelihood of bias, not mere ownership. Therefore, parties must focus on transparency, proper disclosures, and evidence-based objections.
Ultimately, this judgment ensures that arbitration remains both fair and efficient, without being derailed by technical or frivolous challenges.
