Judicial Activism in India: Vitality of Constitutionalism and Fragility of Legislative Authority

The trajectory of Indian constitutional democracy has been profoundly shaped by the judiciary’s proactive interventions in mediating the boundaries between the legislature, executive, and judiciary. Judicial activism, as a mode of constitutional interpretation, extends beyond the passive adjudication of disputes to encompass purposive, creative, and often expansive readings of constitutional provisions in order to safeguard rights, principles, and the balance of power. In the Indian context, this phenomenon embodies a paradox: on the one hand, it demonstrates the vitality of constitutionalism by ensuring that the Constitution remains a “living document” responsive to evolving challenges; on the other, it underscores the fragility of legislative authority, as repeated judicial incursions into the domain of policy and lawmaking can erode parliamentary sovereignty and disrupt the principle of separation of powers.

This essay examines this paradox by critically situating judicial activism within India’s constitutional scheme, and then elucidating landmark cases where judicial interventions have fundamentally altered the scope of parliamentary powers.

1. Judicial Activism and Constitutionalism

Constitutionalism is predicated on the limitation of governmental power and the primacy of the Constitution as a higher-order norm. In this sense, judicial activism sustains constitutionalism by ensuring that legislative and executive acts conform to constitutional principles, particularly the protection of fundamental rights and the preservation of basic democratic structures. The Indian judiciary, especially the Supreme Court, has often assumed the role of the “guardian of the Constitution,” not merely through judicial review but through expansive interpretations that adapt constitutional provisions to new social and political realities.

Key drivers of this activism include:

• Weaknesses in parliamentary oversight and executive accountability, especially during periods of one-party dominance.
• Public interest litigation (PIL), which expanded judicial access and empowered the court to address systemic injustices.
• The doctrine of basic structure, which fortified constitutional supremacy over parliamentary majorities.

In this regard, judicial activism represents the vitality of constitutionalism: it prevents the tyranny of the majority, protects minorities and vulnerable groups, and ensures that democratic procedures remain embedded within substantive constitutional values.

2. The Fragility of Legislative Authority

However, the same activism also demonstrates the fragility of parliamentary sovereignty in India’s constitutional system. Unlike the British Parliament, which enjoys absolute sovereignty, the Indian Parliament is constrained by constitutional supremacy. The judiciary has repeatedly asserted its authority to review and, in some cases, annul parliamentary enactments on grounds of unconstitutionality. This tension is particularly visible in cases concerning constitutional amendments, where the judiciary has set substantive limits on Parliament’s amending power.

While these interventions protect constitutionalism, they simultaneously question the representative legitimacy of the legislature. Critics argue that excessive judicial activism risks converting the Supreme Court into a super-legislature, displacing elected representatives and eroding the principle of democratic accountability. Thus, judicial activism, while indispensable for constitutional vitality, simultaneously exposes the precariousness of legislative authority in India’s democratic order.

3. Landmark Cases Reshaping Parliamentary Powers

A critical appreciation of key judicial pronouncements illuminates how the judiciary has altered the contours of legislative authority in India.

(a) Shankari Prasad v. Union of India (1951) and Sajjan Singh v. State of Rajasthan (1965):
These early cases addressed the question of whether Parliament could amend Fundamental Rights under Article 368. The Supreme Court upheld Parliament’s amending power, affirming the primacy of the legislature in constitutional reform. At this stage, judicial restraint rather than activism characterised the court’s approach.

(b) Golaknath v. State of Punjab (1967):
In a dramatic reversal, the Court held that Parliament could not amend Fundamental Rights, asserting that such rights were “transcendental.” This decision curtailed legislative authority significantly, reflecting a more activist stance and intensifying tensions between constitutionalism and parliamentary sovereignty.

(c) Kesavananda Bharati v. State of Kerala (1973):
This watershed case enshrined the Basic Structure Doctrine, which held that Parliament’s amending power under Article 368 was not unlimited and that amendments damaging the basic structure of the Constitution (e.g., democracy, rule of law, judicial review, secularism) were invalid. While affirming parliamentary power to amend, the Court simultaneously circumscribed it within substantive constitutional boundaries. This doctrine epitomises the judiciary’s dual role: a bulwark of constitutionalism and a constraint on legislative sovereignty.

(d) Indira Nehru Gandhi v. Raj Narain (1975):
In the aftermath of the Emergency, the Supreme Court struck down the 39th Amendment, which sought to immunise the election of the Prime Minister from judicial review. The Court held that free and fair elections were part of the basic structure, and hence Parliament could not immunise electoral outcomes from judicial scrutiny. This intervention directly curbed legislative attempts to entrench executive dominance.

(e) Minerva Mills v. Union of India (1980):
The Court invalidated provisions of the 42nd Amendment that sought to give primacy to Directive Principles over Fundamental Rights and restrict judicial review. By asserting that “limited amending power” itself formed part of the basic structure, the Court fortified its position as the guardian of constitutional equilibrium and reined in legislative supremacy.

(f) Waman Rao v. Union of India (1981):
The Court distinguished between constitutional amendments made before and after Kesavananda Bharati, upholding the latter only if they respected the basic structure. This case consolidated the judiciary’s supervisory role over constitutional amendments and narrowed legislative authority further.

(g) Indra Sawhney v. Union of India (1992):
Though primarily about reservations, this case exemplified the judiciary’s role in determining the permissible scope of parliamentary policies. By upholding 27% OBC reservations while striking down provisions for reservations in promotions, the Court entered the terrain of socio-economic policy design, thereby directly influencing legislative discretion.

(h) I.R. Coelho v. State of Tamil Nadu (2007):
The Court extended the basic structure doctrine to laws placed under the Ninth Schedule after 1973, holding that judicial review could not be excluded even by such protective devices. This reaffirmed the Court’s supremacy over parliamentary attempts to immunise laws from constitutional scrutiny.

(i) NJAC Case (2015):
The Court struck down the 99th Constitutional Amendment, which sought to replace the collegium system of judicial appointments with the National Judicial Appointments Commission. By invoking the basic structure doctrine to preserve judicial independence, the Court significantly curtailed legislative and executive authority in the domain of appointments, triggering debates over judicial overreach.

4. Evaluating the Balance

The cumulative effect of these cases underscores a paradoxical dynamic. Judicial activism has:

• Vitalised constitutionalism by establishing substantive limits on parliamentary power, preserving democratic accountability, and ensuring that transient political majorities do not erode foundational principles.
• Exposed the fragility of legislative authority by restricting Parliament’s role as the supreme law-making body and transferring final interpretive authority to unelected judges.

This balance reflects India’s unique constitutional design, where constitutional supremacy rather than parliamentary sovereignty is the governing principle. Judicial activism ensures that constitutionalism prevails even at the expense of legislative authority, but the normative debate continues over whether this undermines the democratic legitimacy of governance.

5. Conclusion

Judicial activism in India represents both the vitality of constitutionalism and the fragility of legislative authority. By asserting its interpretive supremacy, the judiciary has preserved the Constitution against authoritarian encroachments, entrenched the doctrine of basic structure, and expanded rights-based jurisprudence. Yet, it has also encroached into legislative and policy domains, raising concerns about judicial overreach and the democratic deficit inherent in unelected institutions shaping governance.

Ultimately, the Indian case demonstrates a dynamic balance: judicial activism, while constraining Parliament, has ensured the survival and resilience of constitutional democracy. The vitality it imparts to constitutionalism outweighs, though does not eliminate, the concerns about the fragility of legislative authority. The paradox endures as an essential feature of India’s constitutional design, reflecting the tension between democratic majoritarianism and constitutional supremacy.
