Understanding the Relationship Between the Union and States Under the Indian Constitution

Introduction

The Indian Constitution establishes a unique federal structure where the power is divided between the Union and the States. This division of power is meticulously outlined in various provisions, especially through the Seventh Schedule. Additionally, several doctrines such as the Doctrine of Nexus, Doctrine of Colourable Legislation, and the Doctrine of Pith and Substance play a crucial role in maintaining this balance.

The Seventh Schedule: Three Lists

The Seventh Schedule of the Indian Constitution divides the subjects of legislation between the Union and the States into three distinct lists:

Union List

The Union List contains subjects of national importance such as defense, foreign affairs, atomic energy, and railways. The Union Parliament has exclusive power to legislate on these matters.

State List

The State List includes subjects of local or state importance like police, public health, and agriculture. The State Legislatures have exclusive authority to legislate on these subjects.

Concurrent List

The Concurrent List encompasses subjects that are of common interest to both the Union and the States, such as criminal law, marriage and divorce, and bankruptcy. Both the Union and State Legislatures can legislate on these matters. However, in case of conflict, the Union law prevails.

Doctrine of Nexus

The Doctrine of Nexus deals with the relationship between the subject matter of legislation and the competence of the legislative body. It ensures that there is a legitimate connection or nexus between the law enacted and the subject over which the legislature has the authority to legislate. This doctrine helps in maintaining the balance of power by preventing arbitrary legislation.

Doctrine of Colourable Legislation

The Doctrine of Colourable Legislation is based on the principle that what cannot be done directly cannot be done indirectly. If a legislative body, under the guise of exercising its lawful power, enacts legislation that it is not competent to pass, such legislation is considered colourable and thus invalid. This doctrine is crucial in preventing legislative overreach.

Doctrine of Pith and Substance

The Doctrine of Pith and Substance is used to determine the true nature or essence of the legislation. When a law is challenged on the grounds that it encroaches upon the jurisdiction of another legislative body, the court examines the 'pith and substance'—the true character—of the legislation. If the core subject falls within the jurisdiction of the enacting body, the law is considered valid, even if it incidentally encroaches on the other jurisdiction.

Conclusion

The intricate relationship between the Union and States under the Indian Constitution is a testament to the country's commitment to federalism. The Seventh Schedule's three lists and various doctrines ensure that this relationship is balanced and harmonious, preventing any undue encroachment by one legislative body over another. Understanding these provisions and doctrines is essential for appreciating the functioning of India's federal structure.
