SC grants relief to Adani, sets aside levy on SEZ electricity

SC Grants Relief to Adani: Customs Duty Cannot Be Levied on SEZ Electricity Supplied to DTA

UPSC Study Note | GS-II & GS-III | Polity, Governance, Economy

1. At a Glance

• The Supreme Court of India (January 5, 2026) ruled that customs duty cannot be imposed on electricity supplied from a Special Economic Zone (SEZ) to the Domestic Tariff Area (DTA), setting aside the 2019 Gujarat High Court judgment. [S1]
• The case centred on Adani Power Limited's coal-based thermal plant at Mundra SEZ, Gujarat — a 4,620 MW facility supplying power under long-term PPAs to distribution companies in Gujarat and Haryana. [S3]
• The ruling is significant for UPSC because it clarifies the fiscal boundary of SEZs, the limits of executive power to levy customs duty, and the rights of taxpayers against invalid levies. [S1][S3]
• Touches on the intersection of SEZ Act 2005, Customs Act 1962, and constitutional principles of no tax without statutory authority. [S1][S2]

2. Why in the News

• January 5, 2026: Supreme Court Bench of Justices Aravind Kumar and N.V. Anjaria allowed Adani Power's appeal, holding the customs levy on SEZ-generated electricity supplied to the DTA lacks statutory authority and has no valid charging event under the Customs Act, 1962. [S1][S3]
• Court directed the jurisdictional Commissioner of Customs to verify claims and issue refunds within 8 weeks, warning authorities against "hyper-technical objections." [S3]
• Dispute originated in February 2010 when the Centre amended customs rules to impose duty on electricity from SEZ to DTA, retrospectively from June 2009. [S3]
• The Gujarat High Court's 2019 judgment had upheld the levy — the SC has now set it aside. [S1][S3]

3. Background & Evolution

• 2005: Special Economic Zones Act, 2005 enacted; Section 53 declares an SEZ a territory outside the customs territory of India — goods moving from SEZ to DTA are therefore treated as imports. [S2]
• Section 30, SEZ Act 2005: Clearance of goods from SEZ to DTA is treated as import and attracts applicable customs duties. However, electricity is not a conventional "good" under the Customs Act, 1962 tariff schedule. [S2]
• June 2009: The Centre sought to impose customs duty on electricity supplied from SEZs to the DTA, with retrospective effect from this date. [S3]
• February 2010: Centre amended Customs Rules to formalise this levy. [S3]
• First round of litigation: Adani Power challenged the levy; Gujarat High Court (first round) initially examined the matter.
• 2019: Gujarat High Court upheld the customs duty levy, denying relief to Adani Power. [S1]
• January 5, 2026: Supreme Court reverses Gujarat HC, holds levy lacks statutory authority and directs refund. [S1][S3]

Key Predecessor Context: - Mundra SEZ is a multi-product SEZ in Kutch district, Gujarat; Adani Power functions as a co-developer within this SEZ. [S3] - Previous disputes involving Mundra plant include compensatory tariff relief before CERC (2017) due to imported coal cost escalation — distinct from this customs duty matter. [S4]

4. Core Static Facts

5. Multi-Dimensional Analysis

Economic

• 4,620 MW plant supplies power to Gujarat and Haryana DISCOMs under long-term Power Purchase Agreements (PPAs) — tariff certainty is critical for electricity pricing downstream. [S3]
• Customs duty on electricity from SEZ to DTA acts as a hidden cost on power purchase, ultimately borne by consumers through tariff; SC ruling removes this distortion. [S1]
• Precedent may benefit other SEZ-based power generators supplying to DTA, reducing their compliance and financial burden.
• The 2026 government move for concessional customs duty on SEZ manufactured goods (30% FOB cap) signals a parallel policy trend of using SEZ-DTA fiscal tools as demand management instruments. [S2]

Legal / Constitutional

• Core principle affirmed: No tax without statutory authority — a foundational rule of taxation law in India; courts have consistently held that a tax levy must have express statutory backing. [S1][S3]
• Customs Act, 1962 does not treat electricity as a "good" amenable to customs duty in the conventional tariff sense — no valid charging event exists for electricity supply from SEZ to DTA. [S1][S3]
• SC ruling on refund of amounts collected under invalid tax affirms the principle that the State cannot unjustly enrich itself through ultra vires levies. [S3]
• Limits executive/delegated legislation: the 2010 amendment to Customs Rules could not override the parent statute's (Customs Act 1962) absence of a charging provision for electricity. [S3]
• Section 53, SEZ Act — SEZ as a territory outside India's customs territory creates a legal fiction that has profound tax implications; SC's ruling navigates the intersection of this fiction with the Customs Act. [S2]

Administrative / Governance

• SC's warning against "hyper-technical objections" by customs authorities reflects a recurring concern about tax administration obstructionism frustrating judicial relief. [S3]
• 8-week refund window imposed directly on the Commissioner of Customs — unusual specificity reflects SC's distrust of administrative delay. [S3]
• Retrospective taxation (from June 2009 via February 2010 amendment) raises governance concerns about regulatory predictability for investors in SEZ infrastructure.

Ethical / Governance

• Retrospective levy (from June 2009) — challenged on grounds of legitimate expectation; businesses made investment decisions under a regime where no such duty existed. [S3]
• Raises broader debate on retrospective taxation and India's investment climate — a recurring UPSC theme (see: Vodafone, Cairn cases).

Environmental

• The Mundra plant is coal-based, making it a significant carbon emitter; no direct environmental angle in this ruling, but the plant's continued operation under stable fiscal terms perpetuates coal dependency — relevant for India's NDC commitments under Paris Agreement. [S3]

6. Recent Developments (Last 12–18 Months)

• January 5, 2026: SC allows Adani Power's appeal; sets aside 2019 Gujarat HC order; holds customs duty on SEZ electricity to DTA lacks statutory authority. [S1][S3]
• January 5, 2026: SC directs Commissioner of Customs to issue refunds within 8 weeks; cautions against hyper-technical objections. [S3]
• 2026 (separate): Government notifies conditional concessional customs duty for SEZ-to-DTA goods to boost manufacturing capacity utilisation amid global trade disruptions — limit set at 30% of highest annual FOB export value in preceding 3 financial years. [S2]

7. Prelims Hooks (High-Density Factual Bullets)

1. Mundra SEZ is located in Kutch district, Gujarat — a multi-product SEZ. [S3]
2. Adani Power's Mundra plant is coal-based thermal with an installed capacity of 4,620 MW. [S3]

13. The Customs Act, 1962 is the parent statute governing customs duties; electricity is not a tariff-schedulable "good" under it for this purpose. [S3]
14. Section 30 of the SEZ Act, 2005 provides that clearances from SEZ to DTA are treated as imports and attract customs duty — but the SC found this does not create a valid levy for electricity specifically. [S2][S3]

8. Mains Relevance

GS Paper Mapping:

Plausible Mains Question Stems: 1. "The Supreme Court's ruling on customs duty on SEZ electricity reaffirms the principle that no tax can be levied without statutory authority. Discuss the legal and economic implications of this judgment for India's SEZ policy." (GS-III / GS-II) 2. "Retrospective taxation has long been a concern for investors in India. In light of the Adani Power–Mundra SEZ case, critically examine how retrospective levies affect investor confidence and India's ease of doing business." (GS-III) 3. "Special Economic Zones were conceived as engines of export-led growth. Analyse the tensions between SEZ fiscal incentives and the customs duty framework when SEZ units supply to the Domestic Tariff Area." (GS-III)

10. Common Errors / Trap Areas

1. Confusing the Gujarat HC ruling (2019) with the SC ruling (2026): The HC upheld the duty; the SC struck it down. Direction of relief is opposite — a common MCQ trap.
2. Mixing up DTA→SEZ and SEZ→DTA tax treatment: DTA-to-SEZ = export (zero-rated); SEZ-to-DTA = treated as import (duty applicable in principle, but not for electricity per SC).
3. Assuming the 2026 concessional duty notification applies to electricity: It applies to manufactured goods, not electricity — these are two distinct SEZ-DTA fiscal measures.
4. Attributing jurisdiction to CERC instead of Customs/SC: The Mundra plant has separate compensatory tariff disputes before CERC. This case is purely a customs duty matter under the Customs Act, not electricity tariff regulation.
5. Confusing Mundra SEZ location: Mundra is in Kutch district, Gujarat — not to be confused with Kandla SEZ (also Gujarat) or Mundra Port separately.
