Judicial review is the power of the Supreme Court and High Courts to examine laws, executive actions, and constitutional amendments to ensure they follow the Constitution. If any law violates Fundamental Rights or the basic structure of the Constitution, the courts can declare it invalid. This system protects citizens’ rights, maintains checks and balances among the branches of government, and upholds constitutional supremacy in India.

Judicial review can be defined as the authority of a court to investigate whether laws or statutes or actions undertaken by the executive or the legislature are in line with the constitution. The court has the capability of declaring them as null and void when they are in conflict with the provisions of the constitution. that is, no law or governmental action can be legal that is contrary to the fundamental principles of the Constitution.

When applied to the situation in India, this power supports the idea that the Constitution is supreme - any laws and governmental acts get legitimacy out of this power. The courts are the protectors of the Constitution, which guarantees that all laws or executive decisions do not flout the constitutional norms.

In one of the concise definitions, judicial review has been defined as the ability of the courts to review and potentially strike down any piece of legislation or executive order that infringes the Constitution.

Empowerment and Provisions of the Constitution

Though the term "judicial review" does not actually feature in the Constitution text, a number of Articles interactively grant the judiciary and, in particular, the highest court the authority to exercise this power.

Key among these:

• Article 13: States that a law that is inconsistent with or derogatory to Fundamental Rights (Part III) shall be void. This gives the court the power to invalidate such laws.
• Article 32: gives individuals the right to go to the Supreme Court to enforce their fundamental rights. This gives the Court the capacity to provide rights by issuing writs in case of violations.
• Article 226: Likewise, it gives High Courts power to grant writs to enforce fundamental rights (and other purposes), which gives power to judicial review all the way up to High Courts.

The judiciary role in interpreting the constitution as well as ensuring its supremacy has structural support provided by other provisions of the constitution (such as the provision of the appellate and original jurisdiction of the apex court).

In this way, the judicial review power is established in India, but not in one provision, and a combination of these Articles and the judicial system organization fortifies this power.

Who Exercises It?

In India, the power of judicial review is vested primarily in:

• Supreme Court of India (SC) - as the apex court, it has the final authority to assess the constitutionality of laws and executive actions.
• High Courts - through their writ jurisdiction under Article 226, High Courts also exercise judicial review, especially in matters concerning Fundamental Rights and administrative actions.

Through this dual structure, both central and state-level laws and executive decisions can be subjected to constitutional scrutiny, ensuring a broader reach of protection.

What Can Be Reviewed?

Under judicial review as practiced by the Supreme Court (and High Courts), a variety of laws and actions can be examined:

• Legislative Acts: Laws passed by Parliament or State Legislatures - if they conflict with constitutional provisions or violate fundamental rights.
• Executive / Administrative Actions: Decisions, orders, regulations, notifications, rules, or administrative measures by government authorities can be challenged if they overstep constitutional or statutory bounds.
• Constitutional Amendments (in certain contexts): While legislative amendments are generally within the power of the Parliament of India power, when they attempt to alter the “basic structure” of the Constitution (judicially recognized core features), the Court can review whether such amendments are valid.
• Judicial Decisions (in limited sense): Some forms of review allow courts to examine previous judicial decisions - for example, through review petitions under certain constitutional provisions - though this is distinct from standard judicial review of executive/legislative actions.

In principle, any law or act at the central or state level — legislative, administrative or quasi-judicial - comes under the potential scrutiny of judicial review if challenged appropriately.

Constitutional provisions for judicial review

Types / Forms of Judicial Review

Scholars and courts often classify judicial review into different types, based on what is being reviewed and on which grounds:,/p>

• Constitutional Judicial Review: Assessment of laws and actions for consistency with fundamental constitutional provisions, including Fundamental Rights and the core structure of the Constitution.
• Statutory Judicial Review: Interpretation and evaluation of statutes or subordinate legislation to check if they conform to parent statutes and constitutional limits.
• Administrative / Executive Review: Scrutiny of administrative decisions, executive orders, rules, and notifications to ensure they do not exceed delegated powers or violate procedural fairness and constitutional rights.
• Procedural vs. Substantive Review: Courts may examine not only whether the correct procedure was followed (procedural review) but also whether the substance of a law or decision is reasonable, just, and within constitutional bounds (substantive review).

Through these varied forms, judicial review offers a flexible yet robust mechanism to uphold constitutionalism across many kinds of state action.

Landmark Cases / Judicial Evolution

The judicial review is a doctrine that has developed over decades in India due to such historic decisions that established its areas and boundaries.

• Although the judicial review developed in the courts of other nations (most notoriously Marbury v. It was embraced early in India via its constitutional formulation and judicial interpretations, as shown in the Madison decision in the United States.
• One such incident was the case of Kesavananda Bharati v. State of Kerala (1973). The Court in this instance stated that although Parliament has broad authority to make amendments to the Constitution, it may not make amendments to its fundamental structure. That doctrine, in its turn, guaranteed that some fundamental features of the Constitution would be sacrosanct; not even the constitutional amendments would be able to alter them.
• Later cases, e.g., I.R. Coelho v. A reaffirmation of the same in State of Tamil Nadu (2007), held that judicial review is also applicable to any law unless it falls under any special constitutional schedule (such as the Ninth Schedule) but contravenes fundamental rights or the basic structure of the Constitution.

Jurisprudence through such has enabled judicial review in India to come into maturity as a very strong doctrine, not a tool of procedure, but a protection of constitutional identity and rights of the individual.

Significance / Role in Indian Democracy

The judiciary review, particularly that of the Supreme Court, is an important aspect that governs constitutional leadership and safeguards the rights of the citizens in various ways:

• Checking and Balancing the Constitution: In monitoring that all laws and government actions adhere to the constitutional norms, the judicial review promotes the Constitution as the highest law.
• Protecting Fundamental Rights: In the event that the fundamental rights of Part III are at stake, the judiciary intervenes to safeguard individual rights against unreasonable or discriminatory state conduct.
• Checks and balances: It makes sure that the legislative and executive branches do not exceed themselves, which is why there is a power balance between the organs of the state.
• Securing Federal / Centre-State Balance: In cases where the division of powers between the Parliament and the State Legislatures is in question, judiciary review assists in deciding the disputes and keeping the federal arrangement.
• Prevention of Abuse / Arbitrary Use of Power: The judicial oversight may be used to abrogate arbitrary or discriminatory laws or executive orders, which would help to keep citizens safe against the misuse of power.
• Protecting Constitutional Identity: Judicial review, by applying such principles as the basic structure, serves to guarantee that values of primary importance to the constitution, such as democracy, rule of law, separation of powers, etc., are not violated, even by constitutional amendments.

Practically, the judicial review usually serves as the last protection of constitutional rule and civil liberties in case other bodies fail. It creates the respect of the people in the system and leaves the state in check.

Limitations / Criticisms

Though the judicial review can have numerous advantages, it is not without its own criticisms and inherent limitations:

• Judicial Overreach / Activism: Critics believe that when the courts meddle too frequently to nullify legislation or intervene in the policy affairs, they are usurping the role of the legislature or the executive - the vote of the people.
• Uncertainty and Instability: Frequent interventions may create uncertainty about what laws will survive, affecting governance stability and long-term policy planning.
• Delay and Backlog: The judicial review process may be time-consuming; the courts are usually overwhelmed, hence slowing down the process of concluding on critical matters.
• Minimal Involvement of Courts in Policymaking: Courts do not necessarily have the greatest expertise regarding policy or socio-economic consequences; comprehensive judicial scrutiny can in effect prevent flexible and situation-specific governance.
• Stress on Democratic Principles: Because judges do not get elected, critics argue that vested with the authority to overrule legislative acts enacted in an elected legislature, erosion of democratic legitimacy can be achieved in a measure.

In these ways, therefore, judicial review is an essential check but its application must be wary and cautious to maintain the balance between constitutional supremacy and democracy and the process.

Conclusion

The judicial review process practiced by the Supreme Court of India (and High Courts) is essential and it serves to uphold the Constitution, safeguard the rights of the citizens, and maintain the rule of law. It empowers the judiciary to act as a guardian of constitutional values, to strike down laws and administrative actions that violate fundamental norms, and to ensure government remains within its constitutional bounds.

Meanwhile, the power is not absolute; it has developed over landmark judicial rulings that both affirm and limit it - in particular, by the doctrine of the basic structure. This balance assists in keeping democracy, accountability and the sovereignty of the Constitution intact and protects the democratic processes and institutional legitimacy.

Judicial review is important in a dynamic and pluralistic society such as in the case of India. It acts as an excellent guarantor of the random implementation of power, protects the rights of individuals and minorities, and contributes to the fragile proportionality of various branches of government. It is due to these reasons that any debate on the topic of the role of the Supreme Court cannot be held without regard to judicial review as a pillar of constitutional government, rather than as a tool of an incidental nature.
