The Income Tax Appellate Tribunal was hearing appeals from M/s. Sarraf Export for assessment years 2005-06 and 2006-07 regarding the disallowance of a deduction claimed under Section 80IB of the Income Tax Act for an amount credited as Duty Entitlement Pass Book. The Tribunal found that the Assessing Officer's withdrawal of the deduction, which was initially allowed, under Section 154 was not valid as the issue was debatable given an amendment to Section 28 and relevant case law. Therefore, the Tribunal allowed the appeals and reversed the orders of the Commissioner of Income Tax (Appeals).
