Litigation Strategies in Pay Discrimination

Pay discrimination occurs when employees receive unequal pay or employment benefits because of a legally protected characteristic or because the employer applies an impermissible discriminatory criterion. In India, litigation may arise under constitutional equality principles, equal-pay jurisprudence, labour legislation, service rules, employment contracts, and applicable anti-discrimination provisions.

A successful litigation strategy generally requires establishing the comparator, difference in remuneration, similarity of work, discriminatory basis, and the legal source of the right to equal treatment.

1. Identify the Legal Basis of the Claim

The first step is to identify precisely why the difference in pay is allegedly unlawful.

Potential grounds may include:

• sex/gender;
• caste or other constitutionally protected status;
• arbitrary classification;
• contractual discrimination;
• unequal pay for substantially similar work;
• violation of applicable service rules;
• discriminatory employment policies.

The legal framework differs depending on whether the employer is a government/public-sector employer or a private employer.

2. Establish the Comparator

A pay-discrimination case normally requires careful identification of the employee or group used for comparison.

Relevant factors can include:

• job duties;
• responsibilities;
• qualifications;
• skill;
• experience;
• working conditions;
• degree of responsibility;
• recruitment requirements; and
• actual work performed.

Job titles alone are not necessarily determinative.

The Supreme Court has repeatedly stressed that the comparison must be based on the substance of the work, rather than merely similar designations.

3. Equal Pay for Equal Work

The constitutional principle of equal pay for equal work has developed primarily through Article 14 and Article 16 jurisprudence, particularly in public employment.

In Randhir Singh v. Union of India (1982), the Supreme Court recognised equal pay for equal work as a constitutional goal flowing from the equality provisions and Directive Principles.

However, the principle does not mean that every difference in salary between two employees is automatically unconstitutional.

Courts examine whether the work is sufficiently comparable and whether the distinction has a lawful basis.

4. Gather Documentary Evidence

Pay-discrimination litigation is highly dependent upon documents.

Important evidence may include:

• employment contracts;
• appointment letters;
• salary slips;
• salary structures;
• increment records;
• promotion records;
• job descriptions;
• organisational charts;
• attendance records;
• performance records;
• internal salary policies;
• recruitment advertisements;
• emails concerning compensation;
• appraisal documents; and
• records showing the comparator's duties and remuneration.

Where direct evidence of discrimination is unavailable, patterns and surrounding circumstances may become important.

5. Compare Actual Work, Not Merely Job Titles

An employer may argue that two employees have different responsibilities even though their titles are similar.

The claimant should therefore document:

What work is actually performed → what responsibility is carried → what qualifications are required → what conditions apply → what remuneration is received.

In State of Punjab v. Jagjit Singh (2017), the Supreme Court considered the principle of equal pay in the context of temporary employees performing duties comparable to regular employees.

The Court emphasised comparison of the nature of duties and responsibilities.

6. Establish the Discriminatory Element

A difference in pay alone does not necessarily establish discrimination.

The claimant should identify the connection between the unequal treatment and the prohibited or arbitrary criterion.

For example:

Employee A and Employee B perform substantially comparable work, but Employee A receives lower remuneration because of gender.

This is stronger than simply showing:

Employee A earns less than Employee B.

The litigation should therefore establish both disparity and unlawful basis.

7. Examine the Employer's Justification

Once a prima facie case is established, the employer may rely upon legitimate explanations for the pay difference, such as:

• seniority;
• experience;
• different qualifications;
• greater responsibilities;
• performance-based compensation;
• geographical location;
• recruitment conditions;
• different employment categories;
• historical pay structures; or
• collectively negotiated arrangements.

The claimant should therefore test whether the stated explanation is genuine, consistently applied and supported by records.

8. Gender-Based Pay Discrimination

The Equal Remuneration Act, 1976 historically provided statutory protection against gender-based wage discrimination. Its subject matter has subsequently been incorporated into the Code on Wages, 2019, which contains provisions concerning non-discrimination in wages on the ground of gender for the same or similar work.

The comparison therefore needs to account for the statutory concept of same or similar work.

In Mackinnon Mackenzie & Co. Ltd. v. Audrey D'Costa (1987), the Supreme Court considered discrimination in remuneration between male and female employees.

Principle: Employers cannot justify gender-based wage differences where employees perform work satisfying the statutory requirements for equal remuneration.

9. Public Employment and Article 14

For government employment, Articles 14 and 16 can provide an important constitutional foundation.

An employee may challenge an arbitrary pay classification if similarly situated employees are treated differently without a rational basis.

In D.S. Nakara v. Union of India (1983), the Supreme Court discussed equality and arbitrary classification in the context of pension benefits.

Although the case concerned pension rather than ordinary wage discrimination, it remains important to the broader principle that similarly situated persons cannot be arbitrarily differentiated.

10. Private-Sector Pay Discrimination

A private-sector employee cannot automatically invoke every constitutional employment guarantee in the same manner as a government employee.

A litigation strategy may instead rely upon:

• statutory labour protections;
• the Code on Wages;
• contractual rights;
• applicable anti-discrimination legislation;
• company policies;
• standing orders;
• collective agreements; and
• general civil/legal remedies where available.

The precise cause of action depends on the facts and the applicable legislation.

11. Class or Group Evidence

Pay discrimination may affect an entire group rather than one employee.

For example, evidence may show that:

• women systematically receive lower starting salaries;
• a particular category of employees receives lower increments;
• similarly situated contract workers receive lower remuneration;
• employees performing substantially similar work are placed into different pay grades without a rational explanation.

Statistical or group-level evidence can help identify patterns, although statistics alone may not establish the legal cause of the disparity.

12. Challenge Arbitrary Classification

A pay structure can be challenged where classification lacks a rational relationship with the objective of the classification.

The traditional Article 14 framework asks whether:

1. persons grouped together share an intelligible differentia; and
2. the differentia has a rational nexus with the objective sought to be achieved.

This principle was explained in Budhan Choudhry v. State of Bihar (1955).

13. Interim Relief

Depending on the nature of the proceeding, a claimant may seek interim relief concerning:

• continuation of benefits;
• prevention of retaliatory action;
• preservation of records;
• disclosure of relevant documents;
• maintenance of existing employment conditions.

Interim relief is discretionary and depends on the applicable procedural law and facts.

14. Protection Against Retaliation

An employee who complains about pay discrimination may subsequently face:

• adverse appraisal;
• transfer;
• disciplinary action;
• termination;
• reduction of responsibilities.

The chronology of events can become important evidence.

Employees should therefore preserve:

• the original complaint;
• acknowledgement;
• emails;
• salary records;
• appraisal records;
• communications following the complaint; and
• documents showing subsequent adverse treatment.

15. Remedies

Depending on the legal framework and forum, possible remedies can include:

• payment of wage difference;
• arrears;
• correction of pay scale;
• equal remuneration;
• compensation where legally available;
• interest;
• declaratory relief;
• injunctions; and
• appropriate disciplinary or regulatory action.

The availability of a particular remedy depends upon the statute and employment relationship.

Important Case Laws

1. Randhir Singh v. Union of India, (1982) 1 SCC 618

The Supreme Court recognised equal pay for equal work as a constitutional principle flowing from Articles 14 and 16 read with Directive Principles.

Relevance: Provides the foundational constitutional basis for equal-pay claims, particularly in public employment.

2. Mackinnon Mackenzie & Co. Ltd. v. Audrey D'Costa, (1987) 2 SCC 469

The Supreme Court dealt with unequal remuneration between male and female employees.

Relevance: Important authority concerning gender-based wage discrimination and the requirement of equal remuneration for comparable work.

3. State of Punjab v. Jagjit Singh, (2017) 1 SCC 148

The Supreme Court examined claims for equal pay by temporary employees performing duties comparable to regular employees.

Relevance: The comparison must focus on the nature of duties and responsibilities rather than merely employment labels.

4. D.S. Nakara v. Union of India, (1983) 1 SCC 305

The Court considered equality in relation to pension benefits and rejected an arbitrary classification that differentiated similarly situated pensioners.

Relevance: Demonstrates the constitutional principle against arbitrary differentiation.

5. Budhan Choudhry v. State of Bihar, AIR 1955 SC 191

The Supreme Court explained the classic reasonable classification test under Article 14.

Relevance: Pay classifications must have an intelligible basis and a rational connection with the objective of the classification where Article 14 applies.

6. State of Haryana v. Charanjit Singh, (2006) 9 SCC 321

The Supreme Court examined equal-pay claims and stressed that the claimant must establish substantial similarity in the relevant work and responsibilities.

Relevance: Equal-pay claims cannot succeed merely because two employees have superficially similar work or designations.

7. Uttar Pradesh Gram Panchayat Adhikari Sangh v. Daya Ram Saroj, (2007) 2 SCC 138

The Supreme Court reiterated that comparison for equal pay requires examination of duties, responsibilities and other relevant employment factors.

Relevance: Courts do not mechanically apply the equal-pay principle without establishing the required degree of similarity.

8. State of Madhya Pradesh v. Ramesh Chandra Bajpai, (2009) 13 SCC 635

The Supreme Court considered the requirements for invoking the equal-pay principle.

Relevance: The burden remains on the claimant to establish that the relevant employees are sufficiently comparable in terms of duties and responsibilities.

Evidence Checklist

Conclusion

The central litigation issue in pay-discrimination cases is not simply "Are two employees paid differently?" It is:

"Are similarly situated employees performing substantially comparable work being treated differently on an unlawful or arbitrary basis?"

A strong legal analysis therefore combines comparator evidence, actual duties, remuneration records, the reason for the disparity, the applicable statutory or constitutional protection, and the employer's justification. The cases of Randhir Singh, Mackinnon Mackenzie, Jagjit Singh, D.S. Nakara, Budhan Choudhry and Charanjit Singh provide important principles for analysing these issues.
