Retrospective Tax Law Amendment Ruled Unconstitutional

The Court held that the retrospective amendment to Section 80-IB(9) of the Income Tax Act, introduced by the Finance (No.2) Act, 2009, was unconstitutional and violative of Article 14 of the Constitution. It found that the term "mineral oil" includes "natural gas" and that the Petitioner had a vested right to the tax benefits, which could not be taken away retrospectively. The Court struck down the Explanation added to Section 80-IB(9) as it breached the rule of law and was deemed arbitrary.

Issues Involved:
1. Constitutional validity of the retrospective amendment to Section 80-IB(9) of the Income Tax Act, 1961.
2. Whether the term "mineral oil" includes "natural gas."
3. Whether the Petitioner has any accrued or vested right.

Issue-wise Detailed Analysis:

1. Constitutional Validity of the Retrospective Amendment to Section 80-IB(9):

The Petitioner, a foreign company engaged in the exploration and production of mineral oil and natural gas in India, challenged the constitutional validity of the retrospective amendment to Section 80-IB(9) of the Income Tax Act, 1961, introduced by the Finance (No.2) Act, 2009. The amendment included an Explanation that all blocks licensed under a single contract shall be treated as a single "undertaking." The Petitioner argued that this amendment was not merely clarificatory but substantive, taking away vested rights, and thus arbitrary and unreasonable, violating Article 14 of the Constitution of India.

The Court examined the legislative history, the original provisions, and the amendment's impact. It noted that the term "undertaking" had acquired a consistent statutory meaning through judicial decisions, indicating that each well or cluster of wells could be considered a separate undertaking. The Court found that the Explanation introduced by the amendment was a departure from this settled interpretation and was not in the nature of a validation. The Court held that the amendment was a substantive change in the law, imposing a new tax liability and could only operate prospectively. The retrospective application of the amendment was deemed unconstitutional, violating Article 14 of the Constitution.

2. Whether the Term "Mineral Oil" Includes "Natural Gas":

The Court addressed whether the term "mineral oil" in Section 80-IB(9) includes "natural gas." The Respondent argued that "mineral oil" should not include natural gas, relying on the Explanation to Section 42 of the Act, which includes both petroleum and natural gas only for that Section. The Court, however, referred to the Constitutional Bench decision in Association of Natural Gas v. Union of India, which held that "natural gas" is a petroleum product and part of mineral oil resources. The Court concluded that in the absence of a specific definition under Section 80-IB, the term "mineral oil" includes both petroleum products and natural gas.

The Court also considered the legislative history and various enactments, noting that the term "mineral oil" has been given a wide meaning to include natural gas. The insertion of sub-clause (iv) to Section 80-IB(9) by the Finance (No.2) Act, 2009, was interpreted to mean that the benefit would also be available for NELP VIII bidders who satisfy the conditions set out in the sub-clause. The Court held that the term "mineral oil" in Section 80-IB includes "natural gas," and the amendment could not be interpreted to deny the benefit of deduction to undertakings engaged in commercial production of natural gas under contracts entered into before NELP VIII.

3. Whether the Petitioner Has Any Accrued or Vested Right:

The Court examined whether the Petitioner had any accrued or vested right to the tax benefits under the original Section 80-IB(9). It noted that a vested right is a legal and enforceable right, which can arise from a contract, statute, or by operation of law. The Court found that the Petitioner had a vested right to the tax benefits, as the benefits were expressly made available with effect from 1.4.1999 by amending Section 80-IA, later becoming part of Section 80-IB(9). The Petitioner had been claiming the benefit of 100% deduction on profits and gains from each well or cluster of wells, which was recognized by the Income Tax Appellate Tribunal (ITAT).

The Court held that the retrospective amendment to Section 80-IB(9) by adding the Explanation took away the vested right of the Petitioner, which had matured after the ITAT's judgments. The amendment was not clarificatory but substantive, imposing a new tax liability and could only operate prospectively. The Court concluded that the amendment was arbitrary, unreasonable, and violative of Article 14 of the Constitution, and thus struck it down.

Conclusion:

The Court allowed the writ petitions, holding that the Explanation to Section 80-IB(9) of the Income Tax Act, introduced by the Finance (No.2) Act, 2009, was unconstitutional and violative of Article 14 of the Constitution of India. The term "mineral oil" in Section 80-IB includes "natural gas," and the Petitioner had a vested right to the tax benefits, which could not be taken away retrospectively. The Court struck down the Explanation added to Section 80-IB(9) as it breached the rule of law and was arbitrary.
