Appellate Tribunal's Exclusive Jurisdiction Upheld Over Assessee Appeals

The Supreme Court affirmed the High Court's ruling that once an appeal is filed by the assessee, the entire order of the Appellate Assistant Commissioner falls under the jurisdiction of the Appellate Tribunal. Consequently, the Board of Revenue cannot exercise its revisional powers over any part of the order. The appeals and special leave petitions by the State of Tamil Nadu were dismissed, emphasizing the comprehensive jurisdiction of the Appellate Tribunal for a unified and thorough review process, prohibiting piecemeal scrutiny by different authorities under the Tamil Nadu General Sales Tax Act, 1959.

Issues Involved:
1. Jurisdiction of the Board of Revenue under the Tamil Nadu General Sales Tax Act, 1959.
2. Scope of the Appellate Tribunal's powers when an appeal is filed by the assessee.
3. Applicability of Sections 34 and 36 of the Tamil Nadu General Sales Tax Act, 1959.

Detailed Analysis:

1. Jurisdiction of the Board of Revenue:
The primary issue was whether the Board of Revenue could exercise suo motu revisional jurisdiction over the part of the Appellate Assistant Commissioner's order that was in favor of the assessee when the other part of the order was already under appeal before the Sales Tax Appellate Tribunal. The High Court had ruled that once an appeal is filed by the assessee, the entire order falls within the purview of the Appellate Tribunal, thereby stripping the Board of Revenue of its jurisdiction to revise the remaining part of the order. The appellant State of Tamil Nadu contested this, arguing that the Board retained the power to review the portion of the order favorable to the assessee since it was not the subject of the appeal.

2. Scope of the Appellate Tribunal's Powers:
The appellant contended that the Tribunal's jurisdiction was limited to the part of the order appealed by the assessee. However, the High Court interpreted Sections 34 and 36 to mean that once an appeal is filed, the Tribunal's jurisdiction extends to the entire order, not just the part contested by the assessee. The Tribunal has the authority to enhance, reduce, or annul the assessment or penalty, even if this means revisiting the favorable part of the order for the assessee.

3. Applicability of Sections 34 and 36:
Section 34(2)(a) and (b) of the Act imposes restrictions on the Board of Revenue's revisional powers. Specifically, the Board cannot revise orders that are subject to appeal before the Tribunal or revision before the High Court. The High Court ruled that this bar applies to the entire order once it is appealed, not just the contested part. Section 36(3)(a)(i) further supports this by allowing the Tribunal to enhance assessments or penalties, indicating that the entire order is under its scrutiny.

Conclusion:
The Supreme Court upheld the High Court's interpretation that once an appeal is filed by the assessee, the entire order of the Appellate Assistant Commissioner falls under the jurisdiction of the Appellate Tribunal. Consequently, the Board of Revenue cannot exercise its revisional powers over any part of the order. The appeals and special leave petitions by the State of Tamil Nadu were dismissed, affirming that piecemeal scrutiny by different authorities is not permissible under the Act. The judgment emphasizes the comprehensive jurisdiction of the Appellate Tribunal once an appeal is filed, thereby ensuring a unified and thorough review process.
