Administrative Law
Rule Against Bias: Nemo Judex in Causa Sua
Master the rule against bias through its legal test, major types, landmark cases, waiver and the doctrine of necessity.
Quick answer
A person should not decide a matter where circumstances create a reasonable apprehension that the decision may not be impartial.
The test and common forms
Bias protects confidence in decision-making, so proof that the decision-maker consciously favoured one side is not always necessary.
Objective appearance
The court asks whether informed circumstances create a reasonable apprehension or real likelihood that bias could affect an independent decision.
Pecuniary and personal bias
A financial stake, close relationship, hostility or personal involvement can disqualify a decision-maker even without proof of actual influence.
Subject-matter or departmental bias
Prior responsibility for the dispute or close institutional alignment may matter, but ordinary policy familiarity or departmental membership is not automatically fatal.
Closed mind
Prejudgment arises where statements or conduct show that the authority has effectively decided the outcome before receiving the affected person's case.
How to apply the rule
Separate a concrete conflict from a general suspicion, then ask whether the law provided a practical alternative decision-maker.
Material participation
Presence, discussion, voting, recommendation or influence can matter. Merely leaving the room for one candidate may not remove influence over a connected selection process.
Doctrine of necessity
A legally disqualified person may exceptionally act where no competent substitute or valid quorum is possible and refusing to act would defeat the statutory function.
Waiver
A person who knows the relevant facts and freely proceeds without objection may lose the point, but waiver requires real knowledge and choice.
Consequence
A decision affected by disqualifying bias is ordinarily set aside and returned to an impartial authority rather than decided on merits by the reviewing court.
Landmark cases
Learn the facts, the rule and why the case matters. The citation alone will not strengthen an answer.
A.K. Kraipak v. Union of India
(1969) 2 SCC 262Facts: A senior forest officer was both a candidate for selection to the Indian Forest Service and a member of the board participating in the selection process.
Legal question: Did the formally administrative character of selection exclude natural justice and the rule against bias?
Held: A candidate's participation in the selection board created a real conflict, and administrative classification did not exclude the rule against bias.
Reasoning: No. The boundary between administrative and quasi-judicial action is thin, and fairness applies where a decision affects interests and requires protection against biased power.
Use in an answer: Use it for personal interest and the reach of natural justice.
Read the judgmentAshok Kumar Yadav v. State of Haryana
(1985) 4 SCC 417Facts: Members of a public-service selection committee were closely related to candidates and withdrew only when those relatives were personally interviewed.
Legal question: What test determines whether participation in a selection process creates disqualifying bias?
Held: The test is whether circumstances create a reasonable apprehension that bias is likely to affect the decision, not whether actual bias is proved.
Reasoning: Actual prejudice need not be proved. The circumstances must be tested for a reasonable apprehension that bias could affect an independent decision.
Use in an answer: Use it for selection bodies, relative interest and the objective test.

Frequently asked questions
Must actual bias be proved?
No. The rule commonly turns on an objective apprehension or likelihood of bias arising from proved circumstances.
Does prior knowledge of a matter always disqualify an official?
No. Expertise or prior official knowledge alone may be permissible. Personal interest, prejudgment or incompatible participation creates the stronger objection.
