Case Note & Summary
The case involves a batch of writ petitions filed by companies operating in Special Economic Zones (SEZs) challenging the constitutional validity of the proviso to Section 115JB(6) of the Income Tax Act, 1961, inserted by the Finance Act, 2011. The petitioners, including M/s Mindtree Ltd, M/s Opto Infrastructure Limited, and others, sought a declaration that the proviso is ultra vires Section 27 of the SEZ Act, 2005 read with the Second Schedule, and hence unenforceable. The background is that the SEZ Act, 2005 provides certain tax exemptions to SEZ units, including exemption from income tax under Section 10AA of the Income Tax Act. However, the Finance Act, 2011 introduced a proviso to Section 115JB(6) which made SEZ units liable to Minimum Alternate Tax (MAT) on their book profits. The petitioners argued that this proviso negates the tax exemption granted under the SEZ Act and is therefore ultra vires. The respondents, Union of India and others, defended the proviso as a valid exercise of legislative power. The court analyzed the provisions of both Acts and applied the doctrine of pith and substance and harmonious construction. It held that the SEZ Act and the Income Tax Act operate in different fields and that the proviso does not conflict with Section 27 of the SEZ Act. The court found that the proviso is a valid taxing provision and dismissed the petitions, upholding the validity of the proviso. The decision was rendered by Justice H.N. Nagamohan Das on 12th June 2013.
