Union of India v. Azadi Bachao Andolan ((2004) 10 SCC 1) established the binding principle that Double Taxation Avoidance Agreement (DTAA) provisions prevail over the Income Tax Act, 1961, where they provide more beneficial treatment to the assessee, and that treaty shopping — routing investments through a treaty jurisdiction to avail DTAA benefits — constitutes legitimate tax planning. While the Mauritius-specific capital gains exemption has been phased out (2016 Protocol, effective 2017-2019), the broader legal principle under Section 90 remains fully operative in 2026. Practitioners advising on cross-border investments, fund structuring, and FDI routing must navigate the post-GAAR landscape (Sections 95-102, effective April 2017) where commercial substance is the critical threshold for treaty benefit claims.

Material facts and procedural history
The case challenged the validity of CBDT Circular No. 789 dated 13 April 2000, which directed Indian tax authorities to accept a valid Tax Residency Certificate (TRC) issued by the Mauritius Revenue Authority as sufficient evidence of residency and beneficial ownership for purposes of the India-Mauritius DTAA. Under Article 13 of this DTAA, capital gains from the alienation of shares of an Indian company by a Mauritius resident were taxable exclusively in Mauritius. Since Mauritius did not impose capital gains tax, investors routing through Mauritius effectively paid zero tax on capital gains from Indian equity investments.
Azadi Bachao Andolan, a Delhi-based public interest organization, filed a PIL challenging the Circular and the treaty shopping practice, arguing that it was being used by investors from third countries (primarily US, UK, and Japanese investors) to evade Indian capital gains tax by establishing shell entities in Mauritius with no genuine business activity. The Delhi High Court allowed the challenge, holding that the Circular facilitated tax evasion.
The Union of India appealed to the Supreme Court, arguing that (a) the DTAA was a sovereign treaty obligation, (b) Section 90 gave it statutory force, (c) the CBDT Circular was a reasonable administrative measure, and (d) treaty shopping was a recognized feature of international tax law.
Ratio decidendi
Section 90 gives DTAAs overriding statutory effect — The Court held that Section 90(2) of the Income Tax Act expressly provides that where the Central Government has entered into a DTAA, the provisions of the DTAA apply to the assessee "to the extent they are more beneficial to him." This creates a statutory hierarchy: the more favourable provision — whether in the Act or the DTAA — applies. This is not a judicial discretion but a statutory mandate.
Treaty shopping is tax avoidance, not tax evasion — The Court distinguished between (a) tax evasion (illegal misrepresentation of facts), (b) tax avoidance (legal structuring to minimize tax), and (c) tax mitigation (using statutory incentives). Treaty shopping falls in category (b) — it is the legal use of a treaty structure that the contracting states voluntarily created. If India considered the Mauritius route detrimental, the remedy was treaty renegotiation, not judicial nullification.
CBDT Circular No. 789 is valid — The Court held that the Circular was a reasonable administrative direction consistent with the DTAA framework. Accepting the TRC as sufficient proof of residency reflected the principle of trust between treaty partners — India could not second-guess the residency determinations of the Mauritius authorities.
Economic policy considerations are for the executive — The Court observed that the India-Mauritius DTAA was designed to attract foreign investment into India. Whether the economic benefits of increased investment outweighed the revenue loss from the capital gains exemption was a policy determination for the executive, not a judicial question.
Current statutory framework
Section 90 (unchanged): Section 90(2) continues to provide that DTAA provisions apply where more beneficial. This principle is binding and applies to all 96+ DTAAs India currently has in force.
India-Mauritius DTAA — 2016 Protocol: Effective from 1 April 2017, the Protocol amended Article 13 to allow India to tax capital gains on shares of Indian companies. The transition was phased: 50% of the Indian domestic rate from April 2017 to March 2019, full domestic rate from April 2019. Capital gains on shares acquired before 1 April 2017 remain grandfathered under the original DTAA.
GAAR (Sections 95-102, effective April 2017): The General Anti-Avoidance Rules empower the Revenue to deny treaty benefits where an arrangement is an "impermissible avoidance arrangement" (IAA). An IAA is one whose main purpose is to obtain a tax benefit and which: (a) creates rights/obligations not ordinarily created between arm's-length parties, (b) results in abuse or misuse of the Income Tax Act, (c) lacks commercial substance, or (d) is carried out in a manner not ordinarily employed for bona fide purposes. GAAR applies to income from arrangements entered into from 1 April 2017 onwards.
India-Singapore DTAA (2017 amendment): Consequentially amended to align with the Mauritius Protocol — capital gains exemption similarly phased out. Other DTAAs (with UAE, Netherlands) have also been renegotiated.
MLI (Multilateral Instrument): India ratified the OECD Multilateral Instrument in 2019, which modifies covered DTAAs to include a Principal Purpose Test (PPT). Under the PPT, treaty benefits can be denied if one of the principal purposes of an arrangement was to obtain the benefit. This effectively codifies a limitation on treaty shopping across most of India's DTAAs.
Practice implications
Treaty benefit claims in 2026: Despite the Mauritius exemption being phased out, Section 90 primacy remains critical for other DTAA benefits — reduced withholding rates on dividends, interest, royalties, and fees for technical services. Practitioners must verify the applicable DTAA provisions and ensure the client qualifies as a beneficial owner in the treaty jurisdiction.
Commercial substance is now essential: Post-GAAR, the most important practical change is that treaty benefits cannot be claimed by entities without commercial substance in the treaty jurisdiction. When advising on investment structuring through jurisdictions like Netherlands, Singapore, or UAE, ensure the holding entity has: (a) a physical office, (b) local employees with decision-making authority, (c) board meetings held in the jurisdiction, (d) substantive business activities beyond investment holding, and (e) independent decision-making (not rubber-stamping instructions from the ultimate investor's jurisdiction).
GAAR defence strategy: When the Revenue invokes GAAR to deny treaty benefits, the taxpayer's primary defence is demonstrating that the arrangement has commercial substance beyond tax benefit. Maintain contemporaneous documentation of: (a) the business rationale for the holding structure, (b) minutes of board meetings showing real decision-making, (c) employment contracts and payroll records in the treaty jurisdiction, (d) local regulatory filings, and (e) evidence that the entity bears real economic risk and performs functions justifying its profit attribution.
Grandfathering of pre-2017 investments: For Mauritius-resident entities that acquired Indian shares before 1 April 2017, the original DTAA exemption continues to apply on disposal. Practitioners should maintain evidence of the acquisition date (contract notes, depository statements, bank records) to support grandfathering claims. The Revenue may scrutinize whether shares acquired before April 2017 were subject to subsequent restructuring that could be argued to constitute a new acquisition.
Interaction with MLI: For DTAAs covered by the MLI (India has covered 93 DTAAs), the Principal Purpose Test applies as an additional requirement. Even if the literal DTAA provisions grant a benefit, the Revenue can deny it under the PPT if obtaining the benefit was one of the principal purposes. This requires practitioners to document non-tax business purposes for every structure.
Fund structuring considerations: For private equity and venture capital funds investing in India, the choice of jurisdiction now depends on a combination of DTAA benefits, GAAR compliance, MLI coverage, and regulatory considerations (SEBI FPI regulations, RBI FDI norms). The "optimal" jurisdiction analysis must consider tax treaty rates, capital gains treatment, GAAR exposure, substance requirements, and regulatory ease of operation. Singapore, Netherlands, and UAE remain common choices, each with distinct advantages and compliance burdens.
Key subsequent developments
- India-Mauritius DTAA Protocol (2016): Phased out capital gains exemption (April 2017-2019).
- GAAR (April 2017): Sections 95-102 of the Income Tax Act — can deny treaty benefits for arrangements lacking commercial substance.
- India-Singapore DTAA amendment (2017): Aligned with Mauritius Protocol.
- MLI ratification (2019): Principal Purpose Test applies to 93 covered DTAAs.
- OECD Pillar One and Two (2024-2026): Global minimum tax and profit reallocation framework — may further reduce treaty shopping incentives.
Frequently asked questions
Can GAAR override DTAA benefits approved in Azadi Bachao?
Yes. GAAR (Sections 95-102) is specifically designed to override treaty benefits in cases of impermissible avoidance arrangements. Section 96 provides that the provisions of GAAR apply "notwithstanding anything contained in this Act or any other law for the time being in force" — which includes DTAAs given statutory force under Section 90. However, GAAR applies only to arrangements entered into from 1 April 2017 onwards. Pre-2017 arrangements continue to be governed by the Azadi Bachao principle without GAAR overlay.
How should practitioners advise clients who still hold pre-2017 Mauritius investments?
Advise clients to: (a) maintain clear documentation of the acquisition date (before 1 April 2017), (b) ensure the Mauritius entity continues to hold a valid TRC at the time of disposal, (c) avoid any restructuring that could be characterized as a new acquisition (bonus issues and stock splits are generally safe, but share swaps or buyback-and-repurchase may be challenged), (d) file Form 10F and other required documentation with the Indian tax authorities when claiming DTAA benefits, and (e) obtain a certificate under Section 197 for reduced withholding if disposing through a block deal or off-market transfer.
What is the impact of the MLI's Principal Purpose Test on Section 90?
The MLI's PPT adds a substantive limitation to DTAA benefits that goes beyond the procedural requirements. Under the PPT, even if a taxpayer meets all the formal requirements of a DTAA provision (residency, beneficial ownership, TRC), the benefit can be denied if it is reasonable to conclude that obtaining the benefit was one of the principal purposes of the arrangement. This effectively creates a two-stage test: (1) does the taxpayer qualify for the benefit under the DTAA? (2) was obtaining the benefit a principal purpose? The PPT is narrower than GAAR (requires only "one of" the principal purposes, not "the main" purpose) but broader in application (covers all DTAA benefits, not just those involving arrangements lacking commercial substance).
Is the TRC still accepted as sufficient proof of residency post-GAAR?
The TRC remains necessary but is no longer sufficient by itself in all cases. CBDT Circular No. 789 was never formally withdrawn, and the TRC continues to be the primary document for establishing treaty residency. However, post-GAAR, the Revenue can look behind the TRC to examine whether the entity has genuine substance in the treaty jurisdiction. If the entity is a shell with no employees, no office, and no decision-making in Mauritius (or any treaty jurisdiction), GAAR can be invoked to deny benefits notwithstanding the TRC. The practical recommendation is to treat the TRC as a necessary but not sufficient condition and maintain comprehensive substance documentation.
