M/S DHARAMPAL SATYAPAL LTD. vs DY.COMMR.OF CEN.EXC..

The Supreme Court held that the withdrawal of tax exemptions under Notification dated July 08, 1999, as per Section 154 of the Finance Act, 2003, was valid and effective from a retrospective date. The Court emphasized the principle of Promissory Estoppel, noting that the Union of India could not unilaterally withdraw the promise of tax exemption made to industries in the North-Eastern region. However, since the constitutional validity of Section 154 was upheld in R.C. Tobacco Private Ltd. v. Union of India, the appellant's claim for exemption was denied, leading to the dismissal of the appeal.
