Reasonable Likelihood of Bias

Reasonable likelihood of bias is a principle associated with the rule against bias, one of the fundamental principles of natural justice. It means that a decision may be questioned where the circumstances are such that there is a reasonable possibility that the decision-maker may not act impartially.

The principle is based on the maxim Nemo Judex in Causa Sua, meaning “no one should be a judge in their own cause.”

The focus is not necessarily on proving that the decision-maker was actually biased. Instead, the court examines the surrounding circumstances to determine whether there is a sufficient basis for concern about impartiality.

Meaning

A reasonable likelihood of bias exists when the circumstances surrounding a decision-maker are such that a reasonable person could apprehend that the decision-maker may be influenced by:

• Personal relationship;
• Financial interest;
• Previous involvement;
• Institutional interest;
• Hostility or favouritism;
• Prior commitment to a particular position; or
• Other relevant circumstances.

The principle protects the fairness and credibility of the decision-making process.

Actual Bias vs Reasonable Likelihood of Bias

The two concepts should be distinguished.

Actual Bias

Actual bias means that the decision-maker was in fact influenced by prejudice, interest or another improper consideration.

Reasonable Likelihood of Bias

Reasonable likelihood of bias concerns the circumstances surrounding the decision-maker and whether they create a reasonable basis for apprehending possible partiality.

Therefore, proving the decision-maker’s actual state of mind is not necessarily required.

Objective Assessment

The question is generally examined from an objective perspective.

The court considers the circumstances rather than merely accepting the subjective belief of the person challenging the decision.

Relevant considerations include:

• Nature of the relationship;
• Financial or personal interest;
• Previous involvement;
• Statements or conduct of the decision-maker;
• Institutional circumstances;
• Nature of the dispute; and
• The applicable statutory framework.

Reasonable Likelihood Does Not Mean Mere Suspicion

A mere allegation that:

“The officer is biased.”

is not sufficient.

There must be objective circumstances supporting the apprehension of bias.

The law therefore distinguishes between:

Mere Suspicion → Insufficient

and

Reasonable Basis for Apprehension → Legally Relevant

Forms of Bias That May Create a Reasonable Likelihood

Pecuniary Bias

A financial interest in the outcome may create a reasonable likelihood of bias.

Dimes v. Grand Junction Canal (1852) is the classic authority concerning pecuniary interest.

Personal Bias

A close relationship, hostility or personal dispute may create a reasonable apprehension of partiality.

Departmental Bias

Previous official involvement or overlapping administrative functions may raise concerns about impartiality.

Gullapalli Nageswara Rao v. APSRTC (1959) is an important Indian authority.

Institutional Bias

The structure or interests of an institution may create circumstances requiring examination for impartiality.

Preconceived Notion

A strongly predetermined position concerning the matter may, depending on the circumstances, create a reasonable concern about impartiality.

A.K. Kraipak v. Union of India (1969)

A.K. Kraipak v. Union of India is one of the leading Indian cases concerning the rule against bias.

A member of the selection board was himself a candidate for selection.

The Supreme Court considered his participation inconsistent with the requirement of fair administrative decision-making.

Importance

The case demonstrates that:

• Administrative decisions must satisfy standards of fairness;
• A decision-maker with a conflicting interest should not participate in the decision;
• Natural justice can apply to administrative functions; and
• The circumstances of decision-making are important when examining bias.

Manak Lal v. Dr. Prem Chand (1957)

In Manak Lal v. Dr. Prem Chand, the Supreme Court considered bias in disciplinary proceedings.

The case is important for the principle that the circumstances must be examined to determine whether they create a reasonable apprehension of bias.

The court does not simply rely upon the personal belief of the person challenging the decision.

Ranjit Thakur v. Union of India (1987)

The Supreme Court considered the question of bias in disciplinary proceedings.

The case is frequently cited in discussions concerning the reasonable apprehension of bias and the objective assessment of circumstances surrounding the decision-maker.

Reasonable Likelihood of Bias and Natural Justice

The principle forms part of the rule:

Nemo Judex in Causa Sua

No one should be a judge in their own cause.

Natural justice therefore requires decision-making to be sufficiently impartial.

The broader framework is:

Natural Justice

→ Rule Against Bias
→ Fair Hearing
→ Reasoned Decision, where required

Reasonable Likelihood of Bias and Article 14

The principle also has a close relationship with Article 14 of the Constitution.

Administrative action must not be arbitrary or unfair.

Where legally significant bias affects administrative decision-making, the resulting action may therefore be examined for compliance with constitutional requirements of fairness and non-arbitrariness.

Reasonable Likelihood vs Reasonable Apprehension

The expressions “reasonable likelihood of bias” and “reasonable apprehension of bias” are closely related but should not be treated as mechanically identical in every case.

Courts have used different formulations depending on the context.

The essential inquiry is whether the circumstances provide an objective and legally sufficient basis for questioning the impartiality of the decision-maker.

Burden of Establishing Bias

The person alleging bias must place sufficient material before the court to establish the relevant circumstances.

A bare allegation or unsupported suspicion is generally insufficient.

The court considers the facts and surrounding circumstances as a whole.

Doctrine of Necessity

The doctrine of necessity provides an important exception.

Where:

• The law requires a particular authority to decide the matter; and
• No alternative competent decision-maker is available,

the authority may be permitted to act despite a potential disqualification.

The doctrine prevents a situation where a matter becomes incapable of decision merely because of the rule against bias.

Consequences of Bias

Where a legally significant likelihood or apprehension of bias is established, the decision may be vulnerable to judicial review.

Depending upon the circumstances, the court may:

• Quash the decision;
• Direct a fresh inquiry;
• Require reconsideration by an impartial authority; or
• Grant another appropriate remedy.

Important Cases

Case	Principle
Manak Lal v. Dr. Prem Chand (1957)	Reasonable apprehension of bias
Gullapalli Nageswara Rao v. APSRTC (1959)	Departmental bias
A.K. Kraipak v. Union of India (1969)	Bias and impartiality in administrative action
Ranjit Thakur v. Union of India (1987)	Objective assessment of apprehension of bias
Dimes v. Grand Junction Canal (1852)	Pecuniary bias

Key Points for Exams

• Reasonable likelihood of bias is connected with the rule against bias.
• It is based on Nemo Judex in Causa Sua.
• It does not necessarily require proof of actual bias.
• The circumstances are assessed objectively.
• Mere suspicion or allegation is insufficient.
• Financial, personal, departmental and institutional circumstances may create a concern about bias.
• A.K. Kraipak is a leading Indian case on administrative bias.
• Manak Lal is important for reasonable apprehension of bias.
• Gullapalli Nageswara Rao is important for departmental bias.
• Ranjit Thakur is relevant to the objective assessment of bias.
• The doctrine of necessity is an important exception.
• A decision affected by legally significant bias may be challenged through judicial review.

Conclusion

The doctrine of reasonable likelihood of bias ensures that administrative decisions are not only actually impartial but are made in circumstances that provide a reasonable basis for confidence in the decision-maker’s impartiality.

The court therefore looks beyond the decision itself and examines the relationship, interest, previous involvement and surrounding circumstances of the decision-maker.

Natural justice requires an impartial decision-making process, not merely an assertion that the decision-maker acted fairly.
