Union of India v Azadi Bachao Andolan: Supreme Court on Section 90 DTAC and CBDT Circular Validity

The 2003 Supreme Court judgment in Union of India and Anr v Azadi Bachao Andolan and Anr is one of the most consequential rulings in Indian international tax law. At its core, the case determined whether a CBDT circular that attempted to restrict the capital-gains exemption available to Mauritius-resident investors under the Indo-Mauritius Double Taxation Avoidance Convention (DTAC), 1983 was valid under Sections 90 and 119 of the Income-tax Act, 1961 — a question that had direct implications for billions of dollars of Foreign Institutional Investor (FII) capital flowing through the Mauritius route into Indian equity markets.

Facts of the case

The Government of India and the Government of Mauritius entered into a Double Taxation Avoidance Convention on 1 April 1983, brought into force by a Notification dated 6 December 1983 issued under Section 90 of the Income-tax Act, 1961 read with Section 24A of the Companies (Profits) Surtax Act, 1964. The DTAC's stated purpose was the avoidance of double taxation, prevention of fiscal evasion, and the encouragement of mutual trade and investment. Article 13 of the DTAC, dealing with capital gains, provided that gains from the alienation of property (other than specifically enumerated categories such as immovable property and ships) by a resident of a Contracting State are taxable only in the State in which that person is resident.

In exercise of its powers under Section 90 of the Act, the CBDT issued Circular No. 682 dated 30 March 1994 clarifying that capital gains accruing to any resident of Mauritius from the alienation of shares of an Indian company would be taxable only in Mauritius under Mauritius taxation laws and would not be liable to tax in India. A large number of FIIs resident in Mauritius invested substantial capital in shares of Indian companies relying on this position. In the year 2000, however, income-tax authorities began questioning the Mauritius residency of certain entities, leading the CBDT to issue a further Circular No. 789 dated 13 April 2000, which gave instructions to Chief Commissioners and Directors General of Income-tax regarding the assessment of cases where the DTAC applied.

Two writ petitions — Civil Writ Petition (PIL) No. 5646 of 2000 and Civil Writ Petition No. 2802 of 2000 — were filed before the Division Bench of the Delhi High Court challenging Circular No. 789. The Delhi High Court allowed both petitions and quashed and set aside Circular No. 789, holding it ultra vires Section 90 and Section 119 of the Act and otherwise bad and illegal. The Union of India and Anr preferred appeals by special leave before the Supreme Court, giving rise to Civil Appeals 8161–8162 and 8163–8164 of 2003.

Issues raised

• Whether CBDT Circular No. 789 dated 13 April 2000 was ultra vires the powers conferred by Section 90 and Section 119 of the Income-tax Act, 1961.
• Whether the CBDT, in issuing Circular No. 789, acted beyond the scope of authority delegated to it under the Indo-Mauritius DTAC and the Act.
• Whether Mauritius-resident entities (including FIIs) could legitimately rely on the DTAC and CBDT Circular No. 682 of 1994 to claim exemption from capital gains tax in India on alienation of shares of Indian companies.
• The proper interpretation of Article 13 (Capital Gains) and Article 4 (Residents) of the Indo-Mauritius DTAC, 1983 in the context of the Act.

What the court held

The Supreme Court dismissed the appeals filed by the Union of India and upheld the judgment of the Delhi High Court, thereby sustaining the quashing of CBDT Circular No. 789 dated 13 April 2000. The operative effect of the Supreme Court's decision, as reflected in the outcome recorded in the source, is that the challenge mounted against Circular No. 789 succeeded: the circular, which had given instructions to tax authorities with respect to the assessment of Mauritius-routed investments in a manner adverse to the taxpayers' position, could not stand as a valid exercise of power under Section 90 or Section 119 of the Act.

The judgment's reasoning, as disclosed in the source, centres on the CBDT's earlier Circular No. 682 of 1994, issued explicitly in exercise of powers under Section 90, which had clarified that capital gains of a Mauritius resident from alienation of shares of an Indian company would be taxable only in Mauritius and not in India. FIIs had invested in Indian equities in reliance on this position. Circular No. 789 of 2000 represented a departure from or qualification of that settled position, and the court found this to be impermissible — the CBDT's power under Section 90 and Section 119 does not extend to issuing instructions that contradict or undermine the treaty position already clarified, particularly where investors had acted in reliance on the earlier circular.

The court also engaged with the structure of the DTAC itself: Article 25 (Mutual Agreement Procedure) provides a specific mechanism for resolving disputes about whether taxation is occurring in accordance with the Convention, requiring the competent authorities of both Contracting States to attempt resolution by mutual agreement. The judgment's analysis of the DTAC's architecture — covering allocation of taxing jurisdiction across dividends, interest, royalties, capital gains, and other heads — informed its conclusion that the unilateral administrative action through Circular No. 789 was inconsistent with both the treaty framework and the enabling provisions of the Act.

Strategy observations

1. The challenge was framed on statutory vires, not treaty interpretation alone. The writ petitions before the Delhi High Court attacked Circular No. 789 as ultra vires both Section 90 and Section 119 of the Act — a dual statutory peg that grounded the constitutional/administrative law challenge firmly in the Income-tax Act's own framework rather than relying solely on international treaty interpretation.

2. Reliance on an earlier, pro-taxpayer CBDT circular was central to the case. The respondents' position was anchored on Circular No. 682 of 1994, itself issued under Section 90, which had unambiguously confirmed the Mauritius-only taxability of capital gains. The existence of this prior circular — and the settled expectations it generated among FIIs — was a material feature of the factual matrix before the court.

3. The PIL route was used alongside a conventional writ. The Delhi High Court disposed of both a PIL (CWP No. 5646 of 2000) and a direct writ (CWP No. 2802 of 2000) together, indicating that the challenge was pursued on both a public-interest and a private-interest basis — a procedural feature that broadened the standing base before the High Court.

4. The Supreme Court proceeded by way of special leave petitions. The Union of India's appeal reached the Supreme Court as Civil Appeals arising out of SLP(C) Nos. 20192–20193 and 22521–22522 of 2002, reflecting the government's decision to escalate after the High Court judgment. The Supreme Court's affirmance of the High Court ruling on the same record gave the respondents' position the imprimatur of finality at the apex level.

5. The DTAC's Mutual Agreement Procedure (Article 25) was part of the court's analytical framework. The judgment's treatment of Article 25 — which mandates bilateral engagement between the competent authorities of India and Mauritius before any unilateral assessment action inconsistent with the Convention — reinforced the conclusion that a unilateral CBDT circular could not substitute for the treaty mechanism.

Why this case matters

Union of India v Azadi Bachao Andolan is a landmark in Indian international tax jurisprudence for at least two reasons. First, it authoritatively confirmed that CBDT circulars issued under Section 90 of the Income-tax Act cannot validly withdraw or restrict benefits that flow from a notified Double Taxation Avoidance Convention, particularly where prior administrative clarifications have generated reliance interests. The ruling drew a clear boundary around the CBDT's administrative power under Sections 90 and 119, establishing that those provisions do not confer authority to override treaty obligations through internal instructions.

Second, the case has served as a foundational reference point in subsequent Indian tax treaty litigation. The Supreme Court's detailed analysis of the Indo-Mauritius DTAC — its residency article (Article 4), capital gains article (Article 13), and mutual agreement procedure (Article 25) — provided a template for how Indian courts should approach the interplay between domestic statute and bilateral tax treaty. The affirmance of the Delhi High Court's quashing order by a bench of Justices Ruma Pal and B.N. Srikrishna, reported across multiple citation series including (2003) 263 ITR 706, (2003) 132 TAXMAN 373, and 2004 (10) SCC 1, has ensured the judgment's wide circulation in tax practice and scholarship. The Mauritius route remained a significant channel for FII investment in India for over a decade after this ruling, and this case was invariably cited in any analysis of the legal validity of that structure.
