STATE OF UTTAR PRADESH AND ORS. vs MODI INDUSTRIES LIMITED

The Supreme Court held that Section 31 of the U.P. Sales Tax Act, 1948, is valid and retroactive, allowing the Revising Authority to restore assessments made prior to the amendment as valid in law. The Court found that the High Court erred in quashing the assessment order, affirming that the amendment applied to both pending and closed assessments. The appeal was allowed, and the High Court's judgment was set aside.
