Burden of Proof in Discrimination Cases

1. Introduction

The burden of proof in discrimination cases concerns the question of who must establish that unequal or discriminatory treatment has occurred. In Indian constitutional and employment law, a person alleging discrimination generally has to first establish a prima facie case showing that he or she was treated differently from similarly situated persons, and that the difference was based on an impermissible or legally irrelevant ground.

Once sufficient foundational facts are established, the burden may effectively shift to the State, employer, or other decision-maker to justify the classification or differential treatment by demonstrating that it has a legitimate basis, reasonable classification, and rational connection with the objective sought to be achieved.

Articles 14, 15 and 16 of the Constitution of India form the principal constitutional framework. Article 16 specifically prohibits discrimination in public employment on specified grounds.

2. Meaning of Burden of Proof

The burden of proof refers to the obligation of a party to establish the facts necessary to support its legal claim.

In a discrimination dispute, the complainant normally needs to establish:

1. That he or she belongs to a protected or relevant class.
2. That the respondent took an adverse or unequal action.
3. That similarly situated persons were treated differently, where comparative treatment is relevant.
4. That the difference in treatment was connected with a prohibited, arbitrary, or irrelevant ground.
5. That the treatment resulted in a denial of equality or another legal right.

The complainant is not necessarily required to prove discriminatory intention in every case. Constitutional equality jurisprudence increasingly focuses on the actual effect and justification of State action rather than merely on the subjective motive of the decision-maker.

3. Prima Facie Case

The first important stage is establishing a prima facie case.

A prima facie case does not mean that the claimant must conclusively prove discrimination at the beginning. Instead, the claimant must produce sufficient facts from which discrimination can reasonably be inferred.

For example, if two employees have substantially identical qualifications, duties and performance records, but one is denied promotion while the other receives it because of caste, sex, religion or another prohibited ground, the circumstances may establish a prima facie case.

The respondent may then be required to demonstrate that the difference resulted from a lawful and relevant criterion rather than discrimination.

4. Comparator and Similarly Situated Persons

A discrimination claim ordinarily becomes stronger when the claimant can identify a comparator—a person who is similarly situated but received more favourable treatment.

The Supreme Court has repeatedly emphasised that equality is ordinarily assessed between persons who are similarly situated. In State of Kerala v. N.M. Thomas, the Court recognised that there is no denial of equality merely because two people are treated differently when they do not belong to the same relevant class.

Therefore, the claimant should establish substantial similarity in matters such as:

• qualifications;
• duties;
• status;
• employment conditions;
• relevant service record;
• applicable rules; and
• circumstances surrounding the challenged decision.

5. Burden in Equal Pay Claims

In equal-pay disputes, the burden can be particularly significant because a claimant must establish that the work performed is substantially equal.

In State of M.P. v. Pramod Bhartiya, the Supreme Court explained that similarity of skill, effort and responsibility must be established when claiming equal pay, and the burden of establishing the necessary similarity rests upon the person alleging discrimination.

Thus, merely showing that two employees have the same designation is generally insufficient. The actual nature of their work and responsibilities must be examined.

6. Burden in Public Employment

Article 16 provides equality of opportunity in matters relating to public employment and expressly prohibits discrimination on specified grounds.

The protection extends beyond merely the initial appointment. It can cover matters such as:

• recruitment;
• promotion;
• selection;
• service conditions;
• termination; and
• other matters relating to employment.

In General Manager, Southern Railway v. Rangachari, the Supreme Court recognised the broad scope of Article 16 in employment matters, including promotion.

Consequently, a public employee challenging discriminatory treatment must establish the relevant unequal treatment, while the State must demonstrate that its decision rests upon a permissible and rational basis.

7. Important Case Laws

1. State of M.P. v. Pramod Bhartiya, (1993) 1 SCC 539

This is an important authority concerning the burden in equal-pay discrimination claims.

The Supreme Court held that a person claiming equal pay must establish the requisite similarity of work, including factors such as skill, effort and responsibility. The burden therefore initially rests on the person alleging discrimination.

Principle: The claimant must establish the factual foundation for an allegation of unequal treatment.

2. General Manager, Southern Railway v. Rangachari, AIR 1962 SC 36

The Supreme Court interpreted Article 16 broadly and held that equality of opportunity in public employment extends to matters relating to employment, including promotion.

Principle: Discrimination in employment cannot be confined merely to the stage of initial appointment.

3. State of Kerala v. N.M. Thomas, (1976) 2 SCC 310

The Court explained that equality does not mean treating everyone identically. Persons who are not similarly situated may legitimately be treated differently if there is a constitutionally permissible basis.

Principle: A discrimination claimant ordinarily needs to demonstrate that the persons compared are similarly situated and that the differential treatment lacks sufficient justification.

4. Anuj Garg v. Hotel Association of India, (2008) 3 SCC 1

The Supreme Court struck down restrictions preventing women from working in establishments where liquor was served. The Court rejected gender stereotypes as a legitimate basis for restricting women's employment.

The decision is particularly important because discrimination can arise from stereotypical assumptions, even when a law or policy appears protective on its face. Later Supreme Court decisions have expressly recognised this aspect of Anuj Garg.

Principle: A discriminatory classification cannot be justified merely by relying on stereotypical assumptions about gender roles.

5. Navtej Singh Johar v. Union of India, (2018) 10 SCC 1

The Supreme Court recognised that discrimination based on sexual orientation is inconsistent with constitutional guarantees of equality, dignity and liberty.

The judgment also rejected a narrow understanding of discrimination and emphasised constitutional morality, dignity and substantive equality.

Principle: Discrimination analysis must account for dignity, identity and the substantive impact of State action.

6. NALSA v. Union of India, (2014) 5 SCC 438

The Supreme Court recognised the constitutional rights of transgender persons and held that discrimination based on gender identity violates fundamental constitutional guarantees.

The judgment reinforced the concept that equality is not merely formal equality but requires protection against discrimination affecting historically marginalised groups.

Principle: Constitutional equality protects gender identity and requires the State to avoid discriminatory treatment.

7. Ravinder Kumar Dhariwal v. Union of India, (2021) 2 SCC 539

The Supreme Court discussed the scope of non-discrimination and recognised that discrimination cannot always be reduced to a single prohibited ground. The judgment referred to the concept of “sex-plus” discrimination, drawing upon Anuj Garg and Navtej Singh Johar.

Principle: Discrimination can arise through the interaction of more than one characteristic and should not always be analysed through an excessively formal or narrow approach.

8. Indra Sawhney v. Union of India, 1992 Supp (3) SCC 217

The Constitution Bench explained the relationship between formal and substantive equality and recognised the concept of protective equality in the context of reservations.

The decision demonstrates that treating everyone identically is not always sufficient to achieve constitutional equality.

Principle: Equality may require differential treatment designed to remedy existing disadvantage, provided that the constitutional requirements are satisfied.

8. Direct and Indirect Discrimination

The burden of proof can become more complicated where discrimination is indirect.

Direct discrimination

This occurs where the adverse treatment is expressly based upon a prohibited ground.

Example:

“Women will not be appointed to this position.”

Here, the discriminatory basis is relatively apparent.

Indirect discrimination

This occurs where a seemingly neutral rule disproportionately disadvantages a particular group.

Example:

An employment requirement appears neutral but disproportionately excludes persons belonging to a particular protected group and cannot be adequately justified.

In such cases, the claimant may need to demonstrate the disparate impact, after which the respondent may have to justify the rule.

9. Discriminatory Intention Is Not Always Necessary

One of the most important developments in equality jurisprudence is that discrimination does not always require proof of an express intention to discriminate.

A rule may be unconstitutional because of:

• its discriminatory classification;
• its disproportionate impact;
• stereotypical assumptions;
• arbitrary differentiation; or
• its effect upon dignity and substantive equality.

The Supreme Court's treatment of gender stereotypes in Anuj Garg illustrates this approach.

10. Burden-Shifting Approach

A useful way of understanding the process is:

Stage 1 – Claimant establishes foundational facts
↓
Stage 2 – Prima facie discrimination is demonstrated
↓
Stage 3 – Respondent explains the differential treatment
↓
Stage 4 – Court examines whether the classification is legally permissible
↓
Stage 5 – Court determines whether the action violates equality/non-discrimination guarantees

The respondent may justify differential treatment by demonstrating:

• a reasonable classification;
• an intelligible differentia;
• a rational nexus with the objective;
• a legitimate governmental or organisational purpose;
• compliance with statutory rules; and
• absence of an impermissible discriminatory basis.

11. Burden in Private Employment

Articles 14–16 primarily operate against the State and public authorities, although statutory and other legal protections can regulate private employers as well.

In a private employment dispute, the burden will depend upon the specific statute, employment contract, workplace policy and nature of the claim.

For example, allegations concerning:

• sex discrimination;
• sexual harassment;
• disability discrimination;
• caste discrimination;
• unequal pay; or
• discriminatory termination

may be governed by different statutory frameworks and therefore may involve different evidentiary requirements.

12. Evidence Relevant to Discrimination

A claimant can strengthen a discrimination case through evidence such as:

1. Appointment and promotion records.
2. Salary and remuneration records.
3. Performance evaluations.
4. Emails and written communications.
5. Workplace policies.
6. Comparative treatment of similarly situated employees.
7. Selection or promotion criteria.
8. Disciplinary records.
9. Statistical evidence where appropriate.
10. Statements of decision-makers.
11. Evidence showing discriminatory remarks or stereotypes.
12. Records demonstrating inconsistent application of rules.

Direct evidence is useful but circumstantial evidence can also be highly important, particularly where discrimination is concealed or the decision-maker does not expressly state the discriminatory reason.

13. Conclusion

The burden of proof in discrimination cases is not necessarily a single, fixed burden throughout the proceedings. Generally, the claimant must first establish sufficient facts showing unequal or adverse treatment and, where relevant, demonstrate that the persons compared are similarly situated. Once a credible prima facie case is established, the respondent may have to explain and justify the differential treatment.

Indian constitutional jurisprudence has increasingly moved from a narrow concept of formal equality towards substantive equality, dignity, non-arbitrariness and protection against stereotypes. Cases such as Pramod Bhartiya, N.M. Thomas, Rangachari, Anuj Garg, NALSA, Navtej Singh Johar and Ravinder Kumar Dhariwal demonstrate different aspects of this approach.

In short: the person alleging discrimination generally has to establish the factual foundation of the claim, but once a prima facie case is made out, the focus shifts to whether the respondent can provide a lawful, rational and constitutionally acceptable justification for the differential treatment.
