Constitutional Safeguards Against Arbitrary Taxation: Role of Articles 14, 19(1)(g) and 265 in Tax Disputes

Introduction

In the current era of intensified tax enforcement, enterprises across India frequently encounter unexpected assessment orders, disproportionate tax demands, Input Tax Credit blockages, and administrative actions that severely disrupt day-to-day business functioning. While the State undeniably holds sovereign power to impose and collect taxes, the Constitution of India simultaneously places firm guardrails around how that power may be exercised.

Three constitutional provisions collectively form the bedrock of protection available to an assessee against unlawful or oppressive fiscal action:

  • Article 14 of the Constitution of India — Guarantees equality before law and prohibits arbitrary or discriminatory State action
  • Article 19(1)(g) of the Constitution of India — Preserves the fundamental right to practise any profession or carry on any occupation, trade, or business
  • Article 265 of the Constitution of India — Mandates that no tax shall be levied or collected except by authority of law

Understanding how these three provisions interact and reinforce each other is essential for any assessee or tax professional navigating complex litigation in today's GST and direct tax landscape.

Article 265: The Foundational Requirement of Legal Authority for Taxation

The Constitutional Text and Its Meaning

Article 265 of the Constitution of India lays down what is perhaps the most fundamental rule in Indian fiscal law: no tax shall be levied or collected except by authority of law. This deceptively simple provision carries enormous practical significance.

The expression "authority of law" does not merely mean the existence of some statute on the books. It demands that:

  1. A valid legislative enactment must specifically authorise the levy in question
  2. The notification or circular through which a tax is operationalised must fall squarely within the scope of the parent statute
  3. Every element of a tax demand — the charge, the rate, the person liable, and the mode of collection — must trace its origin to a lawful provision
  4. Executive instructions, office memoranda, or departmental circulars cannot, on their own, create or extend a tax liability that the statute itself does not support

Practical Implications for an Assessee

Where a tax authority raises a demand, blocks ITC, or initiates recovery proceedings without a clear statutory foundation, the assessee can invoke Article 265 directly. Courts have consistently held that a levy unsupported by proper legal authority is constitutionally void, regardless of any administrative convenience that the department may cite in its defence.

Important: A circular issued by a tax authority that purports to impose an obligation beyond what the governing statute permits is not merely irregular — it is constitutionally impermissible under Article 265.

This provision therefore functions as the first line of constitutional defence for an assessee facing any form of tax action.

Article 14: Equality Before Law and Protection Against Arbitrary Taxation

Scope of Article 14 in Fiscal Matters

Article 14 of the Constitution of India guarantees equality before law and equal protection of the laws within the territory of India. A common misconception is that taxation statutes enjoy blanket immunity from constitutional challenge. This position has been firmly and repeatedly rejected by Indian courts.

Even where a tax has the backing of legislation — thereby satisfying Article 265 — it must independently pass the test of reasonableness and non-arbitrariness embedded in Article 14. A tax law that:
