Issues Involved:
1. Constitutionality of the Notification No. 2598-F.T. dated August 1, 2001.
2. Retrospective effect of the notification from January 1, 2000.
3. Violation of Article 14 of the Constitution of India.

Issue-Wise Detailed Analysis:

Constitutionality of the Notification No. 2598-F.T. dated August 1, 2001:
The petitioner challenged the constitutionality of the notification under section 8 of the West Bengal Taxation Tribunal Act, 1987. The notification imposed tax on "rab" retrospectively from January 1, 2000. The petitioner argued that this retrospective imposition was arbitrary and violated Article 14 of the Constitution of India.

Retrospective Effect of the Notification from January 1, 2000:
The notification dated August 1, 2001, brought "rab" under the taxable category with retrospective effect from January 1, 2000. The petitioner contended that this retrospective effect was unreasonable as no tax was collected on "rab" during this period, and the dealers would have to pay the tax from their own pockets.

Violation of Article 14 of the Constitution of India:
The petitioner argued that the retrospective imposition of tax created inequality among dealers. Those whose assessments were completed before the notification were exempt from tax, while others whose assessments were completed after the notification were liable to pay tax, violating Article 14 of the Constitution.

Legality of Retrospective Tax Imposition on "rab":
The Tribunal examined whether the retrospective imposition of tax on "rab" was valid. It was found that the concept of "rab" was not known to the revenue authorities before 2000, and "rab" was treated as "gur" and non-taxable. The Tribunal concluded that the retrospective imposition was not clarificatory or explanatory but imposed a new tax liability.

Differentiation between "gur" and "rab":
The Tribunal referred to the Supreme Court's explanation in Krishi Utpadan Mandi Samiti v. Shankar Industries, which clarified the difference between "gur" and "rab". "Rab" is a semi-solid form of sugar-cane juice, whereas "gur" is hardened and fit for human consumption. The Tribunal found that the revenue authorities had no idea about "rab" before 2000.

Legislative Competence for Retrospective Taxation:
The Tribunal referred the matter to a Larger Bench to adjudicate whether the Legislature is competent to legislate with retrospective effect. The Tribunal considered various judgments, including D. Cawasji & Co. v. State of Mysore and Bengal Paper Mill Co. Ltd. v. Commercial Tax Officer, which held that retrospective imposition of tax could be arbitrary and unreasonable.

Reasonableness of Retrospective Tax:
The Tribunal examined the reasonableness of the retrospective tax. It found that the retrospective amendment imposed an unexpected financial burden on the dealers, who did not collect tax during the period in question. The Tribunal concluded that the retrospective operation of the amendment was arbitrary, unreasonable, and violated the fundamental rights guaranteed by the Constitution.

Conclusion:
The Tribunal held that the retrospective operation of the amendment by Notification No. 2598-F.T. dated August 1, 2001, was arbitrary, unreasonable, and ultra vires the fundamental rights guaranteed by the Constitution. The prospective part of the amendment was deemed constitutional and valid. The assessment of tax on sales of "rab" for the period ending on March 31, 2001, was reduced to nil.

Post-Judgment:
The Tribunal granted an interim stay of the judgment's operation till November 10, 2008, restraining the respondents from realizing the demand set aside by the judgment.
