New Delhi: June 04, 2026:
Equality is one of the cornerstones of the Indian Constitution. Articles 14 to 18 enshrine guarantees against discrimination, ensuring equal protection of laws, equality of opportunity, and abolition of untouchability and titles. Yet, the lived reality of equality in India is complex, shaped by caste, gender, religion, and socio‑economic divides.
The regulation of petroleum products plays a crucial role in ensuring uninterrupted fuel availability and preventing unfair trade practices. For a detailed understanding of the legal framework governing the supply, storage, and distribution of petroleum products in India, readers may refer to the Oil Regulation of Supply and Distribution Order, 1998, which prescribes important compliance requirements for stakeholders in the petroleum sector.
The judiciary has played a pivotal role in interpreting and expanding these guarantees. From striking down discriminatory laws to upholding affirmative action, courts have consistently emphasized that equality is not just formal but substantive. Landmark cases on reservations, gender rights, and LGBTQ+ equality have transformed the constitutional landscape, making equality a dynamic principle rather than a static promise.
Globally, India’s jurisprudence on equality is studied for its balance between individual rights and social justice. As debates on affirmative action, digital equality, and intersectionality grow, the judiciary’s role will only deepen. This article explores the constitutional foundations of equality, landmark cases, judicial activism, global comparisons, citizen activism, and the future of equality in India.
Section 1: Constitutional Foundations

- Article 15: Prohibition of discrimination.
- Article 16: Equality of opportunity in public employment.
- Article 17: Abolition of untouchability.

- Judicial interpretation of substantive vs. formal equality.
Section 2: Landmark Equality Cases
1. Indra Sawhney v. Union of India (1992)
This landmark case, popularly known as the Mandal Commission case, tested the limits of affirmative action. The Supreme Court upheld reservations for Other Backward Classes (OBCs) but introduced a 50% cap to prevent excessive quotas. It also excluded the “creamy layer” from benefits, ensuring that affirmative action reached the truly disadvantaged. The judgment balanced meritocracy with social justice, redefining equality as substantive rather than formal.
2. Navtej Singh Johar v. Union of India (2018)
In a historic ruling, the Supreme Court struck down Section 377 of the IPC, decriminalizing homosexuality. The Court emphasized that equality under Article 14 extends to LGBTQ+ citizens, affirming dignity and autonomy. This judgment was celebrated globally as a milestone in human rights, making equality inclusive of sexual orientation.
3. Vishaka v. State of Rajasthan (1997)
Sparked by the gang rape of a social worker, this PIL led the Supreme Court to establish guidelines against workplace sexual harassment. Known as the Vishaka Guidelines, they filled a legislative vacuum until the 2013 law was enacted. The case expanded equality to include safe workplaces, linking gender justice to constitutional rights.
4. N.M. Thomas v. State of Kerala (1976)
This case upheld affirmative action in promotions for disadvantaged groups. The Court ruled that equality is not just about treating everyone the same but about addressing historical disadvantages. It marked a shift toward substantive equality, recognizing that fairness sometimes requires differential treatment.
5. Shayara Bano v. Union of India (2017)
This PIL challenged the practice of instant triple talaq. The Supreme Court struck it down as unconstitutional, affirming gender equality in personal laws. The judgment reinforced that religious practices cannot override constitutional guarantees of equality and dignity.
6. State of Madras v. Champakam Dorairajan (1951)
One of the earliest equality cases, it struck down caste‑based reservations in educational institutions. The ruling led to the First Constitutional Amendment, which allowed special provisions for disadvantaged groups. It highlighted the tension between formal equality and social justice in India’s early constitutional history.
7. E.P. Royappa v. State of Tamil Nadu (1974)
This case expanded Article 14 by linking equality with non‑arbitrariness. The Court ruled that arbitrary state action violates equality, making fairness a constitutional requirement. It transformed equality from a narrow concept into a broad principle of governance.
8. Maneka Gandhi v. Union of India (1978)
Though primarily about personal liberty, this case linked Article 14 with Article 21, ensuring equality in due process. The Court ruled that laws must be fair, just, and reasonable, embedding equality into procedural safeguards.
9. Olga Tellis v. Bombay Municipal Corporation (1985)
Pavement dwellers challenged their eviction, arguing it deprived them of livelihood. The Court recognized the right to livelihood as part of the right to life, linking equality to socio‑economic justice. It expanded constitutional protections to marginalized communities.
10. Ashoka Kumar Thakur v. Union of India (2008)
This case upheld OBC reservations in educational institutions. The Court reinforced affirmative action as a tool for substantive equality, while also emphasizing the exclusion of the creamy layer. It balanced access to education with fairness.
11. National Legal Services Authority (NALSA) v. Union of India (2014)
In a groundbreaking judgment, the Court recognized transgender persons as a third gender. It affirmed their right to equality, dignity, and non‑discrimination. The ruling was a milestone in expanding constitutional protections to marginalized identities.
12. Joseph Shine v. Union of India (2018)
This case struck down the adultery law, which treated women as property of men. The Court ruled it violated gender equality and autonomy. The judgment modernized personal laws, aligning them with constitutional values of dignity and equality.
13. Indian Young Lawyers Association v. State of Kerala (2018, Sabarimala Case)
This PIL challenged the ban on women’s entry into the Sabarimala temple. The Supreme Court ruled the ban unconstitutional, affirming equality in religious practices. The case sparked national debate but reinforced that constitutional guarantees override discriminatory traditions.
14. Lt. Col. Nitisha v. Union of India (2021)
Women officers in the Army challenged discriminatory promotion criteria. The Supreme Court ruled in their favor, addressing gender bias in military service. The judgment expanded equality into defense services, ensuring that women receive equal opportunities in national institutions.
Section 3: Judicial Activism in Equality
Judicial activism has been a defining feature of India’s constitutional journey, particularly in the realm of equality. Courts have consistently expanded the meaning of equality beyond its textual boundaries in Articles 14–18, interpreting it as a principle that encompasses dignity, fairness, and non‑discrimination. This dynamic approach has allowed the judiciary to respond to evolving social realities, ensuring that equality is not confined to formal legal guarantees but extends to substantive justice. For instance, rulings on gender rights, LGBTQ+ equality, and workplace harassment demonstrate how courts have infused dignity into the constitutional promise of equality, making it a lived experience rather than an abstract principle.
A central challenge has been balancing affirmative action with meritocracy. The judiciary has upheld reservations as a means to achieve substantive equality, recognizing that disadvantaged groups require special measures to overcome historical injustices. At the same time, it has introduced safeguards such as the “creamy layer” exclusion to prevent misuse and ensure fairness. This balancing act reflects the Court’s effort to harmonize social justice with efficiency, acknowledging that equality sometimes requires differential treatment to achieve genuine fairness.
However, judicial activism in equality has not been without criticism. Detractors argue that courts often encroach upon policy domains, issuing directives that should be the prerogative of legislatures or executives. For example, guidelines on workplace harassment or interventions in reservation policies have raised concerns about judicial overreach. Critics caution that excessive activism risks undermining democratic processes, while supporters contend that it fills governance gaps and protects vulnerable groups.
Ultimately, judicial activism in equality illustrates the evolving nature of constitutional law in India. By expanding equality to include dignity and non‑discrimination, while carefully balancing affirmative action with merit, the judiciary has ensured that constitutional promises remain relevant in a diverse and changing society.
