From Double Jurisprudence to Double Taxation: Constitutional Safeguards under the provisions of Constitution of India.

I. INTRODUCTION

The Constitution of India establishes a federal structure characterised by a dual polity comprising the Union and the States. This structural dualism necessarily produces a dual jurisprudence—distinct yet coordinated legal and legislative spheres operating concurrently within the same constitutional order. A related constitutional concern is double taxation, i.e., the possibility that the same subject matter or the same taxable event may be burdened twice by different taxing authorities.

The Constitution, through a complex scheme of distribution of legislative powers, doctrines developed by the judiciary, and later structural reforms such as the introduction of the Goods and Services Tax (GST), provides significant safeguards against both jurisprudential conflict and taxation overlap. This paper analyses the constitutional architecture that prevents such duplicative or inconsistent legal regimes.

II. DOUBLE JURISPRUDENCE: CONSTITUTIONAL FOUNDATION AND LIMITATIONS

A. Dual Polity and Legislative Compartments

The constitutional design envisages a distribution of legislative competence between the Union and the States through Article 246 read with the Seventh Schedule.

• List I (Union List) confers exclusive legislative competence on Parliament.
• List II (State List) vests plenary authority in State Legislatures.
• List III (Concurrent List) is a domain of shared competence.

This triadic distribution creates two independent streams of law-making—hence a form of “double jurisprudence”—but the Constitution places strict limitations to avoid jurisdictional overlap and normative inconsistency.

B. Doctrine of Pith and Substance

The doctrine mandates that legislative competence is determined by examining the true nature and character of a law rather than its incidental encroachments. This doctrine ensures:

• territorial and subject-matter exclusivity,
• avoidance of unintended overlaps, and
• reinforcement of federal balance.

C. Doctrine of Repugnancy (Article 254)

In matters listed under the Concurrent List, if a State law is repugnant to a Parliamentary law:

• the Parliamentary law prevails, and
• the State law becomes void to the extent of repugnancy.

Exception: A State law reserved for and receiving Presidential assent may prevail within that State unless Parliament subsequently enacts an overriding law.

This doctrine prevents conflicting or duplicative legal commands arising out of dual legislative authority.

III. DOUBLE TAXATION: CONSTITUTIONAL SAFEGUARDS AND JUDICIAL CONSTRUCTION

A. Constitutional Allocation of Taxing Powers

The Constitution segregates taxing fields through Articles 246, 268–281, and the respective entries in the Union List and State List. The underlying principle is that:

• each taxing field must be referable to a distinct taxable event,
• neither the Union nor the State may encroach upon the other’s taxation domain, and
• no tax may be imposed unless it is expressly enumerated in the legislative lists.

Thus, constitutional allocation itself operates as a primary safeguard against double taxation.

B. Article 265: Prohibition Against Unauthorised Taxation

Article 265 mandates:

“No tax shall be levied or collected except by authority of law.”

This principle ensures that:

• taxation must be expressly authorised by a valid law,
• overlapping or duplicate impositions without legislative authority are unconstitutional,
• executive or delegated levy cannot create incidental double taxation.

It acts as a substantive as well as procedural restraint against arbitrary fiscal burdens.

C. Aspect Theory

The Supreme Court has evolved the aspect theory to determine whether two taxes imposed by different authorities are constitutionally valid. A single transaction may possess multiple aspects, each of which may be taxed by different governments provided:

• each tax falls within its respective legislative competence, and
• the two taxes operate on different aspects, not on the same taxable event.

This doctrine prevents true double taxation while preserving constitutionally assigned sovereignty over taxation.

D. GST and the Constitutional Elimination of Cascading Taxes

The 101st Constitutional Amendment (2016) introduced the Goods and Services Tax (GST), a destination-based consumption tax that subsumes multiple indirect taxes. GST addresses structural double taxation by:

1. combining taxes on goods and services into a single levy on “supply,”
2. introducing the input tax credit mechanism to eliminate cascading effect,
3. creating the GST Council for harmonisation of tax structures.

This reform significantly removed the earlier problem of the same transaction being separately taxed by Union and State across multiple stages.

E. International Double Taxation Avoidance (Article 253)

Article 253 empowers Parliament to enter into treaties and agreements, including Double Taxation Avoidance Agreements (DTAAs), which provide:

• exemptions,
• tax credit mechanisms, and
• residency-based or source-based allocation rules.

These treaties prevent the same income from being taxed twice by both India and another sovereign state, ensuring global economic fairness and preventing fiscal impediments to cross-border commerce.

IV. JUDICIAL PRECEDENTS RELEVANT TO DOUBLE TAXATION AND OVERLAP

1. State of West Bengal v. Kesoram Industries (2004)

The Supreme Court distinguished between tax and fee, clarified the importance of distinct taxable events, and emphasised that overlapping taxation violates constitutional allocation.

2. Federation of Hotel & Restaurant Assn. of India v. Union of India (1989)

The Court upheld aspect theory and held that different taxes on different aspects of the same transaction do not constitute prohibited double taxation.

3. Bimolangshu Roy v. State of Assam (2018)

The Court held that even if two legislatures incidentally impose similar fiscal burdens, they must be referable to distinct fields of competence.

V. SYNTHESIS: CONSTITUTIONAL PROTECTION FROM DUPLICATIVE LEGAL AND TAXATION BURDENS

From the foregoing doctrines, the following constitutional mechanisms provide robust protection against double jurisprudence and double taxation:

1. Exclusive and exhaustive division of legislative fields in the Seventh Schedule.
2. Judicial doctrines (pith and substance, aspect theory, repugnancy) that ensure interpretational discipline.
3. Authoritative prohibition under Article 265 against unauthorised levies.
4. Harmonisation through GST, eliminating multi-stage indirect tax duplication.
5. International coordination through DTAAs under Article 253 preventing cross-border double taxation.

Collectively, these elements ensure that although India operates under a dual federal structure with dual legislative authority, the Constitution maintains coherence, prevents fiscal redundancy, and preserves the integrity of the federal balance.

VI. CONCLUSION

The movement “from double jurisprudence to double taxation” reflects the inherent tension within a federal system characterised by divided legislative competence. However, the Constitution of India—through meticulous distribution of powers, entrenched limitations, and interpretative doctrines—effectively prevents duplication, inconsistency, and arbitrary taxation. The constitutional framework thus safeguards both legal unity and fiscal integrity, while respecting the autonomy of the Union and the States.
