The Constitution of India is the supreme law of the land, establishing the framework within which legislative, executive, and judicial powers are distributed among various organs of the State. One of the essential features of the Constitution is the principle of separation of powers and the demarcation of legislative competence between the Union and the States.

To preserve this balance, constitutional jurisprudence in India has evolved several doctrines that ensure that no authority exceeds the limits imposed upon it by the Constitution. Among these doctrines, the Doctrine of Colourable Legislation, also known as the Doctrine of Colourable Variation, holds a place of critical importance. This doctrine is a judicial tool used to determine whether a legislature, while purporting to act within its powers, has in substance transgressed the limits of its constitutional authority by adopting a disguised form of legislation.

The doctrine is rooted in the Latin maxim “Quando aliquid prohibetur ex directo, prohibetur et per obliquum”, meaning that what cannot be done directly cannot be done indirectly. In essence, the doctrine of colourable legislation prevents a legislative body from achieving indirectly what it cannot do directly. It operates as a constitutional check on the legislature’s power to ensure that legislative actions are not camouflaged attempts to encroach upon subjects outside their jurisdiction.

This doctrine does not question the wisdom, motive, or policy behind legislation but focuses on the substance of the law rather than its form. If the legislature enacts a law in a guise that ostensibly appears to fall within its legislative competence but in reality deals with a subject reserved for another authority, the law is considered colourable and hence unconstitutional.

Historical and Constitutional Foundations

The doctrine of colourable legislation traces its origin to the principle of distribution of legislative powers in federal constitutions. In India, legislative powers are distributed between the Union and the States under Articles 245 and 246 of the Constitution, read with the Seventh Schedule. The Seventh Schedule contains three lists: the Union List (List I), the State List (List II), and the Concurrent List (List III). The Union Parliament can make laws on matters enumerated in the Union List, the State Legislatures can legislate on matters in the State List, and both can legislate on subjects in the Concurrent List. Any legislative action must, therefore, conform to these constitutional boundaries.

If a legislature enacts a law on a matter that falls outside its assigned field, it is considered ultra vires, meaning beyond its powers. However, situations often arise where the legislature attempts to legislate on a prohibited subject indirectly, by disguising the true nature of the legislation. It is in such circumstances that the doctrine of colourable legislation becomes relevant. The judiciary, while interpreting the Constitution, developed this doctrine to ensure that legislative competence is not subverted by artful drafting or political manoeuvring.

The doctrine is not unique to India. It finds its origin in the constitutional practices of other federal nations such as Canada and the United States. The Privy Council and the Supreme Court of Canada had, in several cases, applied this principle to strike down laws that attempted to encroach upon federal or provincial jurisdictions under the guise of legitimate legislation. In India, the Supreme Court adopted and refined this doctrine to suit the federal structure and unique constitutional philosophy embodied in the Indian Constitution.

Meaning and Nature of Colourable Legislation

The term “colourable legislation” refers to a situation where a legislature, though appearing to act within its authority, in reality legislates on a matter beyond its competence by giving the law a deceptive appearance. The colour or form of the legislation is used as a mask to hide its true substance. The doctrine is not concerned with whether the legislature has acted in good faith or bad faith. The test is objective rather than subjective. What matters is the substance and effect of the legislation, not its external appearance or declared object.

The doctrine of colourable legislation rests on two fundamental principles of constitutional law. The first is that the Constitution distributes powers among different organs and levels of government, and these limitations must be respected. The second is that legislative bodies cannot circumvent these limitations through indirect methods. Thus, when a law is challenged on the ground of legislative incompetence, the court examines whether, in substance and effect, the legislature has encroached upon a field reserved for another authority.

This doctrine does not deal with malafide intentions or political motives. Courts have consistently held that the legislature, being a sovereign body within its sphere, cannot be questioned on the ground of motive. Therefore, the question of colourable legislation arises not from the motive but from the disguise adopted by the legislature to enact a law on a subject it is not constitutionally competent to deal with.

Judicial Interpretation and Evolution in India

The doctrine of colourable legislation was first elaborately discussed by the Supreme Court of India in the landmark case of K.C. Gajapati Narayan Deo v. State of Orissa (1953). In this case, the Orissa Agricultural Income Tax (Amendment) Act, 1950, was challenged on the ground that it was enacted by the State Legislature to confiscate the properties of the zamindars under the guise of imposing a tax. The petitioners argued that the legislature lacked the competence to pass the law since it, in substance, sought to deprive individuals of property rather than impose a genuine tax.

The Supreme Court, in a seminal judgment delivered by Justice Mukherjea, explained the scope of the doctrine. The Court observed that the motive or intention of the legislature is irrelevant and cannot be questioned. What must be examined is the true nature and character of the legislation. The Court held that if, in substance, the law falls within the competence of the legislature, it cannot be declared invalid merely because it was passed with some ulterior purpose. Conversely, if the law, though apparently within competence, is in reality beyond it, the legislation is colourable. In that case, however, the Court upheld the validity of the Orissa Act, finding that it was genuinely a taxation measure and not a disguised attempt to expropriate property.

Another leading decision that clarified the doctrine was State of Bihar v. Kameshwar Singh (1952), where the Bihar Land Reforms Act, 1950, was challenged. The Act aimed to abolish the zamindari system and acquire estates, but the petitioners contended that the compensation provisions were illusory and that the law was, in substance, a colourable device to confiscate property without compensation. The Supreme Court held that while the legislature was competent to enact land reform laws under its powers, the compensation provisions were unconstitutional because they violated Article 14. The Court acknowledged the doctrine but held that the legislation was not colourable in its entirety. Instead, certain parts of the law were struck down for violating fundamental rights.

Over time, several other cases refined the doctrine. In C.B. Gautam v. Union of India (1993), the Supreme Court reiterated that the doctrine of colourable legislation is invoked when the legislature exceeds its constitutional limits by disguising its true objective. Similarly, in R.S. Joshi v. Ajit Mills Ltd. (1977), the Court emphasized that the doctrine is an analytical tool to examine legislative competence rather than to assess legislative motives.

In State of Madhya Pradesh v. G.C. Mandawar (1954), the Court held that the doctrine does not apply when the legislature is competent to enact a law but the law is alleged to violate fundamental rights. The Court clarified that colourable legislation arises only when there is a transgression of legislative competence, not when the legislature acts within its field but allegedly unreasonably. Hence, the doctrine is confined strictly to cases of legislative power distribution and not to issues of violation of constitutional rights.

Application and Relevance in Indian Constitutional Jurisprudence

The doctrine of colourable legislation serves as a safeguard against legislative encroachment. Its application has been most frequent in cases involving the federal distribution of powers. The Indian Constitution, while federal in structure, also provides for a strong Centre. The Union and State legislatures are expected to legislate within their respective spheres. However, since many subjects overlap or are interrelated, disputes often arise over whether a particular law falls within the Union or State List. Courts, in such cases, apply the doctrine of colourable legislation to determine the true nature of the law.

For instance, if a State Legislature enacts a law ostensibly relating to “public order,” which is within the State List, but the real effect of the law is to regulate “communication” or “inter-state trade,” which are subjects under the Union List, the law may be declared colourable. The doctrine ensures that legislative bodies do not use creative drafting to disguise laws that intrude into areas reserved for other authorities.

The doctrine also plays a significant role in maintaining constitutional supremacy. The Constitution is the ultimate source of legislative power, and every law derives its validity from the Constitution. By invoking the doctrine, courts ensure that legislative competence is not undermined by deceptive tactics. This promotes accountability, transparency, and the rule of law.

Relation with Other Constitutional Doctrines

The doctrine of colourable legislation is closely related to other constitutional doctrines, such as the Doctrine of Pith and Substance, Doctrine of Severability, and Doctrine of Repugnancy. While each doctrine serves a distinct purpose, they often overlap in cases concerning legislative competence.

The Doctrine of Pith and Substance determines the true nature and object of a law to decide under which list it falls. If the pith and substance of the law relate to a matter within the competence of the legislature, the law is valid even if it incidentally touches upon a subject in another list. The doctrine of colourable legislation, however, goes a step further. It applies when the legislature deliberately disguises a law to make it appear within its competence, while its real substance falls outside. In other words, pith and substance focuses on incidental encroachment, whereas colourable legislation deals with disguised encroachment.

The Doctrine of Severability comes into play when part of a law is unconstitutional. If the valid and invalid parts of a law can be separated, the valid portion is upheld. In cases of colourable legislation, if only certain provisions are colourable, the court may apply severability to save the rest of the law.

The Doctrine of Repugnancy, applicable under Article 254, deals with conflicts between Union and State laws on subjects in the Concurrent List. While it concerns inconsistency between valid laws, colourable legislation concerns legislative competence itself.

Doctrine of Colourable Legislation and Judicial Review

The judiciary in India has the power of judicial review under Articles 32 and 226 of the Constitution. Judicial review ensures that all laws conform to constitutional provisions. The doctrine of colourable legislation is one of the key instruments of judicial review used to test the constitutional validity of statutes. When a law is challenged, courts examine whether the legislature had the competence to enact it, whether it falls within the legislative list assigned to it, and whether the law is a genuine exercise of power or a disguised encroachment.

Courts have developed various interpretative tools to apply this doctrine effectively. They look at the object, scope, effects, and consequences of the legislation. The mere title or preamble of a law is not conclusive. Even if a law is couched in terms that appear to be within legislative power, the court will strike it down if its operation or effect falls outside. Thus, the judiciary plays a critical role in preserving the federal balance by preventing colourable exercises of power.

The doctrine also underscores the principle of constitutional morality. Legislatures are expected to act in good faith and respect the constitutional limits of power. Any attempt to disguise legislative intent or circumvent constitutional prohibitions is inconsistent with this morality. Through the doctrine, courts ensure that constitutional governance is not undermined by manipulative law-making.

Criticism and Limitations of the Doctrine

While the doctrine of colourable legislation serves an essential constitutional purpose, it is not without criticism. One major criticism is that the doctrine can be difficult to apply in practice. Determining whether a law is colourable often involves subjective interpretation of legislative intent and the law’s effect. This can lead to judicial overreach or inconsistency in application.

Another limitation is that the doctrine applies only to issues of legislative competence, not to questions of fundamental rights violations or policy. Therefore, if a law is within legislative competence but violates fundamental rights, it cannot be struck down as colourable; it must be tested on the ground of rights infringement. Similarly, the doctrine cannot be invoked merely because a law appears politically motivated or unfair.

Moreover, the doctrine assumes a clear demarcation of legislative fields. However, in modern governance, subjects often overlap. For example, areas like environmental regulation, taxation, and digital communication involve aspects of multiple lists. In such cases, determining whether a law is truly colourable becomes complex. The courts, therefore, must exercise restraint and rely on the doctrine only in clear cases of disguised encroachment.

Despite these criticisms, the doctrine continues to hold significant relevance. It acts as a constitutional reminder that legislative powers are not absolute and that the spirit of federalism must be preserved.

Contemporary Relevance and Conclusion

In contemporary India, with increasing legislative innovation and political competition between the Centre and the States, the doctrine of colourable legislation remains highly relevant. Legislatures may sometimes attempt to push constitutional boundaries through creative drafting or populist measures. The doctrine ensures that such attempts do not undermine the balance of power. For example, in fiscal and economic matters, both the Union and the States have overlapping interests. The doctrine acts as a safeguard against one level of government encroaching upon the powers of another through legislative manipulation.

In recent years, courts have continued to emphasize substance over form. The doctrine serves as a constitutional check not only on the states but also on Parliament. It reinforces the supremacy of the Constitution and the accountability of all law-making bodies to constitutional norms. In a democratic framework based on the rule of law, such judicial scrutiny is vital to maintaining equilibrium and ensuring justice.

In conclusion, the Doctrine of Colourable Legislation is a cornerstone of Indian constitutional jurisprudence. It embodies the fundamental constitutional principle that the legislature must act within its assigned powers and cannot evade constitutional limitations by indirect means. By focusing on the substance and effect of legislation, rather than its form, the doctrine ensures that legislative power is exercised honestly and within constitutional limits. It preserves the delicate federal balance, prevents abuse of authority, and upholds the integrity of the constitutional framework.

As India continues to evolve as a vibrant democracy with complex governance challenges, the doctrine of colourable legislation will remain an indispensable judicial tool. It stands as a testament to the enduring wisdom of constitutionalism: that power must always be checked by law, and that even the highest legislative bodies are bound by the spirit and letter of the Constitution.
