The learned counsels appearing on either side do not dispute the fact that the issue involved in these Writ Petitions is covered by a decision of the Hon'ble Supreme Court, in the case of Commissioner of Income-tax Vs. Avani Exports reported in [2015] 58 Taxmann.com 100 (SC), wherein, the Hon'ble Supreme Court, considered the validity of the amendment to Section 80 HHC (3) of the Income Tax Act, 1961, in which, third and fourth proviso to Section 80HHC were inserted by Taxation Laws (Second Amendment) Act, 2005, with retrospective effect from 1-41998. By virtue of the said amendment, two categories of exporters, viz., those, whose exports were less than Rupees Ten crores, and those exporters, whose export turnover was more than Rupees Ten crores. It provided that, deduction in respect of exporters having a turnover of more than Rupees Ten crores would be available only if they had satisfied two conditions stipulated in third and fourth proviso to the said amendment. All the exporters, including assessees, contended that these conditions are severable, and, therefore, these conditions should be declared as ultra vires. The High Court accepted the contentions of the exporters/assessees and quashed the impugned amendment only to extent that the operation of said Section could be given effect from the date of amendment, and not in respect of earlier assessment years. Accordingly, the Hon'ble Supreme Court confirmed the view taken by the High Court, and held that the conditions stipulated in third and fourth proviso to Section 80HHC of the Income Tax Act, would not operate retrospectively, and cases of exporters, having a turnover below Rupees Ten crores, and those above Rupees Ten crores, would be treated similarly during the period prior to amendment.
