Judicial review of delegated legislation is one of the most significant aspects of administrative law and constitutional governance, serving as an essential mechanism for ensuring that powers delegated by the legislature to administrative authorities are exercised within legal and constitutional limits. In modern welfare states, legislatures are often unable to enact detailed laws governing every aspect of public administration due to the increasing complexity of governmental functions, rapid technological developments, and the need for flexibility in responding to changing social and economic conditions.
As a result, legislatures frequently delegate law-making powers to the executive branch, government departments, local authorities, regulatory agencies, statutory bodies, and other administrative institutions. This process is known as delegated legislation, subordinate legislation, or secondary legislation. Delegated legislation includes rules, regulations, notifications, orders, schemes, bylaws, circulars, and other instruments made by authorities under powers conferred by a parent statute or enabling Act.
While delegated legislation plays a crucial role in effective governance, it also raises concerns regarding accountability, democratic legitimacy, and the potential misuse of power. Since delegated legislation is created by bodies that are not directly elected by the people, judicial review becomes an indispensable safeguard to ensure that delegated powers are exercised lawfully, reasonably, and consistently with legislative intent. Judicial review of delegated legislation refers to the power of courts to examine the validity, legality, constitutionality, and propriety of subordinate legislation and to declare it invalid if it exceeds the authority granted by the legislature or violates constitutional principles.
The primary objective of judicial review in this context is to maintain the supremacy of the Constitution, uphold the rule of law, preserve legislative control over delegated powers, and protect individuals against arbitrary or excessive exercises of administrative authority. The historical development of judicial review of delegated legislation is closely linked to the expansion of the administrative state during the nineteenth and twentieth centuries. As governments assumed greater responsibility for regulating economic activities, public health, education, labor relations, environmental protection, and social welfare, legislatures increasingly relied on delegated legislation to implement policy objectives. Courts recognized that although delegation was necessary for practical governance, there was also a need to ensure that administrative authorities did not exceed the limits imposed by Parliament or the Constitution. Consequently, judicial review emerged as a legal mechanism through which courts could supervise delegated legislation and prevent abuses of delegated power.
One of the most important grounds for judicial review of delegated legislation is the doctrine of ultra vires. The term “ultra vires” means “beyond the powers,” and the doctrine is based on the principle that administrative authorities possess only those powers that have been granted to them by the legislature. If a rule, regulation, notification, or order exceeds the powers conferred by the enabling statute, it may be declared ultra vires and invalid. The doctrine of ultra vires is generally divided into substantive ultra vires and procedural ultra vires. Substantive ultra vires occurs when delegated legislation exceeds the scope of authority granted by the parent Act. For example, if a statute authorizes a regulatory authority to prescribe licensing procedures but the authority creates regulations imposing taxes, such regulations may be invalid because taxation powers were not delegated. Procedural ultra vires arises when the authority fails to comply with mandatory procedural requirements specified in the enabling legislation. For instance, if a statute requires prior consultation with stakeholders before issuing regulations and the authority fails to conduct such consultation, the resulting regulations may be struck down.
Through the doctrine of ultra vires, courts ensure that delegated legislation remains subordinate to legislative intent and does not become an instrument of unauthorized law-making. Another important ground for judicial review is inconsistency with the parent statute. Delegated legislation derives its validity from the enabling Act and must therefore conform to its provisions, objectives, and purposes. If subordinate legislation conflicts with the parent Act, expands its scope beyond what the legislature intended, or frustrates its objectives, courts may declare it invalid. The rationale behind this principle is that delegated authorities cannot override or amend the provisions of primary legislation. Parliament alone possesses the authority to enact or modify statutory law, and delegated legislation must remain consistent with the legislative framework established by the parent statute.
Courts often engage in statutory interpretation to determine whether delegated legislation aligns with legislative intent. If a conflict exists between the parent Act and subordinate legislation, the provisions of the parent Act prevail. Judicial review based on inconsistency therefore preserves legislative supremacy and prevents administrative authorities from assuming powers reserved for the legislature. Constitutional invalidity constitutes another significant ground for judicial review of delegated legislation. In constitutional democracies, all laws, including delegated legislation, must conform to constitutional provisions and principles. Courts may strike down delegated legislation if it violates fundamental rights, exceeds constitutional limitations, infringes the separation of powers, or conflicts with constitutional values.
In India, for example, delegated legislation may be challenged under Articles 13, 14, 19, 21, and other provisions of the Constitution. If a regulation imposes unreasonable restrictions on freedom of speech, violates equality before the law, or deprives individuals of liberty without due process, courts may declare it unconstitutional. The constitutional review of delegated legislation ensures that administrative authorities remain subject to constitutional constraints and that fundamental rights are protected against executive overreach.
This aspect of judicial review reinforces the supremacy of the Constitution and strengthens democratic governance. The doctrine of reasonableness also plays an important role in judicial review of delegated legislation. Courts may invalidate subordinate legislation if it is manifestly unreasonable, arbitrary, oppressive, or irrational. Although courts generally exercise restraint and avoid substituting their policy preferences for those of administrative authorities, they may intervene where regulations lack a rational basis or impose excessive burdens without justification. The principle of reasonableness is closely linked to the rule of law because arbitrary exercises of power are incompatible with constitutional governance. For example, a regulation imposing disproportionate penalties for minor violations may be challenged on the ground that it is unreasonable.
Similarly, delegated legislation based on irrelevant considerations or unsupported assumptions may be subject to judicial scrutiny. The doctrine of reasonableness ensures that delegated legislation remains fair, rational, and consistent with legal principles. Closely related to reasonableness is the principle of proportionality, which has become increasingly important in contemporary administrative law. Proportionality requires that measures adopted through delegated legislation must be suitable to achieve legitimate objectives, necessary in the sense that no less restrictive alternatives are available, and balanced so that the benefits outweigh the harm caused to affected individuals. Courts applying proportionality analysis examine whether delegated legislation imposes excessive restrictions on rights or interests relative to the objectives pursued.
This principle is particularly relevant in cases involving fundamental rights, human rights, and regulatory measures affecting economic freedoms. If delegated legislation goes beyond what is reasonably necessary to achieve its intended purpose, courts may declare it invalid. Proportionality thus serves as an important safeguard against excessive administrative regulation and promotes balanced governance. Judicial review of delegated legislation also encompasses the doctrine of mala fide or bad faith. Administrative authorities must exercise delegated powers honestly, in good faith, and for the purposes intended by the legislature. If delegated legislation is enacted for improper purposes, personal gain, political favoritism, or other unauthorized objectives, it may be challenged as mala fide.
Although proving bad faith can be difficult, courts recognize that delegated powers must be exercised in the public interest rather than for private or ulterior motives. The doctrine serves as a safeguard against abuse of power and reinforces accountability in administrative governance. Another significant ground of review involves improper delegation or excessive delegation. While legislatures may delegate certain law-making functions to administrative authorities, they cannot abdicate their essential legislative responsibilities. The doctrine of excessive delegation requires legislatures to provide adequate guidance, standards, and policy frameworks when conferring delegated powers. If a statute grants unfettered discretion without establishing clear principles or limitations, it may be challenged as an unconstitutional delegation of legislative authority.
Courts examine whether the legislature has laid down sufficient policy guidelines and whether the delegated authority operates within those parameters. This doctrine preserves the separation of powers and ensures that fundamental legislative functions remain with elected representatives. In India, the Supreme Court has repeatedly emphasized that while delegation is permissible, essential legislative functions cannot be delegated. Procedural fairness also influences judicial review of delegated legislation. Many enabling statutes require administrative authorities to follow specific procedures before issuing rules or regulations, such as publishing draft regulations, inviting public comments, consulting stakeholders, or obtaining approval from higher authorities. Compliance with these procedures enhances transparency, accountability, and public participation in the regulatory process.
Failure to observe mandatory procedural requirements may render delegated legislation invalid. Courts assess whether procedural safeguards have been respected and whether affected individuals have been given appropriate opportunities to participate in the decision-making process. Procedural review therefore contributes to the legitimacy and quality of delegated legislation. In India, judicial review of delegated legislation has evolved through a rich body of constitutional and administrative jurisprudence. The Supreme Court has consistently affirmed that delegated legislation is subject to judicial scrutiny on grounds such as lack of legislative competence, violation of fundamental rights, inconsistency with the parent statute, arbitrariness, unreasonableness, mala fide exercise of power, and excessive delegation.
Landmark decisions have emphasized that delegated legislation must remain within the limits prescribed by the Constitution and the enabling Act. Indian courts have also recognized that while judicial review is essential for maintaining constitutional governance, courts should exercise restraint and respect the expertise of administrative authorities in matters involving technical, economic, and policy considerations. This balanced approach seeks to preserve both administrative efficiency and constitutional accountability. Judicial review of delegated legislation performs several important functions in a democratic society. It protects citizens from arbitrary and unlawful exercises of administrative power, preserves legislative supremacy by ensuring that delegated authorities remain within their statutory limits, upholds constitutional values and fundamental rights, promotes transparency and accountability, and reinforces public confidence in governmental institutions.
Without judicial review, delegated legislation could become a source of unchecked executive power, undermining democratic principles and individual liberties. By subjecting delegated legislation to legal scrutiny, courts help maintain the balance between administrative flexibility and constitutional control. In an era characterized by expanding governmental functions and increasing reliance on administrative regulation, judicial review remains an indispensable mechanism for safeguarding the rule of law and ensuring that delegated powers are exercised responsibly. Ultimately, the judicial review of delegated legislation reflects the broader constitutional principle that all exercises of public power, whether legislative, executive, or administrative, must remain subject to legal limits and judicial oversight, thereby preserving the values of justice, accountability, fairness, and democratic governance.
