Proviso to Section 113 Income Tax Act is prospective, not retrospective, favoring clear tax laws and taxpayer rights

The SC held that the proviso to Section 113 of the Income Tax Act, inserted by the Finance Act, 2002, is prospective, not retrospective. The Court ruled that tax imposition must be clear and unambiguous, and where ambiguity exists, the interpretation favoring the taxpayer prevails. The principle against retrospectivity is grounded in fairness, requiring that laws modifying accrued rights or imposing new obligations be prospective unless legislative intent for retrospectivity is explicit. Procedural provisions or those conferring benefits may be retrospective if clearly intended. Applying these principles, the SC ruled against the revenue, emphasizing that tax liability cannot be imposed without clear statutory authority and that retrospective taxation without clear intent violates fundamental fairness.

Issues Involved:
1. Whether the proviso appended to Section 113 of the Income Tax Act, inserted by the Finance Act, 2002, is to operate prospectively or is clarificatory and curative in nature and, therefore, has retrospective operation.

Issue-wise Detailed Analysis:

1. Background Facts:
The case revolves around a search and seizure operation conducted under Section 132 of the Income Tax Act on the premises of the assessee on 10.02.2001. The assessee filed a return for the block period from 01.04.1989 to 10.02.2000, and the Block Assessment was completed under Section 158BA on 28.02.2002. The Assessing Officer later observed that surcharge had not been levied and passed a rectification order under Section 154 on 30.06.2003. This order was challenged and subsequently canceled by the CIT (Appeals) on the grounds that the levy of surcharge is a debatable issue. The CIT issued a notice under Section 263 to revise the order, leading to a series of appeals culminating in the present case.

2. Reference to Larger Bench:
The core issue about the proviso to Section 113, whether it is clarificatory and curative and thus retrospective, was referred to a Constitution Bench. The Division Bench in the case of Commissioner of Income Tax, Central II v. Suresh N. Gupta had held that the proviso is clarificatory. However, doubts about this view led to the constitution of a larger Bench.

3. Statutory Provisions:
Section 4 of the Income Tax Act is the charging section, and the rate or rates at which income tax is charged are specified annually by the Finance Act. The power to levy surcharge is contained in Article 271 of the Constitution. The relevant provisions for block assessment are contained in Chapter XIV-B, which lays down a special procedure for the assessment of search cases. Section 113, before the insertion of the proviso, stipulated a tax rate of 60% for block assessments.

4. Judgment in Suresh N. Gupta:
The Division Bench in Suresh N. Gupta held that the proviso to Section 113 is clarificatory, addressing the ambiguity regarding the applicable date for surcharge rates. The Court concluded that the proviso merely clarified that the relevant date for the applicability of the Finance Act is the year in which the search is initiated.

5. Analysis and Conclusion:
The Constitution Bench undertook a detailed analysis of the scheme of Chapter XIVB and the principles of retrospectivity. It concluded that Chapter XIVB is a complete code in itself for assessing undisclosed income, with Section 158BA(2) as the charging section. The Bench emphasized that the proviso to Section 113 could not be treated as clarificatory or curative and thus could not have retrospective effect. The general principle against retrospective operation was applied, noting that the proviso imposes an additional burden on the assessee.

6. Reasons for Prospective Operation:
- The ambiguity regarding the levy of surcharge before the proviso was acknowledged, with different dates being considered for applying the surcharge rate.
- The Department itself recognized the difficulty in justifying the levy of surcharge in block assessments.
- The legislative intent, as indicated in the Notes on Clauses and the CBDT circular, was to make the amendment prospective.
- The Finance Act, 2003, further clarified that surcharge in block assessments was intended to be prospective.

7. Conclusion:
The appeals filed by the Income Tax Department were dismissed, and the appeals of the assessees were allowed, deleting the surcharge levied for the block assessment period prior to 1st June 2002. The judgment in Suresh N. Gupta was overruled, establishing that the proviso to Section 113 is prospective in nature.
