Manak Lal v Dr. Prem Chand Singhvi

Facts

• A disciplinary tribunal constituted to inquire into a complaint against a legal practitioner included a member who had a prior professional relationship with one of the parties
• The impartiality of the tribunal's composition was challenged on the ground that this prior connection gave rise to a reasonable apprehension of bias, even without specific proof that the member had actually been influenced

Issue

1. What is the correct legal test for determining disqualifying bias in a tribunal member or adjudicator: proof of actual bias, or a reasonable apprehension or likelihood of bias?

Held

• The principle of nemo judex in causa sua requires that an adjudicator be free not only from actual bias but also from any reasonable apprehension of bias in the mind of a fair-minded, reasonable observer
• Proof of actual prejudice or partiality is not necessary; it is sufficient that the circumstances give rise to a real and reasonable likelihood of bias
• Where such a reasonable apprehension exists, the adjudicator ought to have recused himself, and failure to do so vitiates the proceedings regardless of whether the outcome was influenced
• Public confidence in the impartiality of adjudication is itself a value the law protects, independent of whether actual unfairness can be demonstrated

Ratio Decidendi

The test for disqualifying bias under the rule against bias (nemo judex in causa sua) is the reasonable likelihood or apprehension of bias, judged from the perspective of a reasonable person, and does not require proof of actual partiality; a genuine reasonable apprehension of bias, arising from a relevant prior connection, is sufficient to vitiate the proceedings.
