Case Note & Summary
The petitioners, Shelf Drilling Ron Tappmeyer Limited, Shelf Drilling J.T. Angel Limited, and Shelf Drilling Trident XII Limited, are companies incorporated in the Cayman Islands and engaged in offshore drilling operations. They filed writ petitions challenging reassessment notices issued under Section 148 of the Income Tax Act, 1961 for assessment years 2014-15 and 2015-16. The notices were issued by the Assistant Commissioner of Income Tax (International Taxation), Mumbai, alleging that income from the operation of drilling rigs in the Indian continental shelf had escaped assessment. The petitioners contended that the notices were time-barred under Section 149, as they were issued beyond four years from the end of the relevant assessment year, and that there was no allegation of failure to disclose material facts. They also argued that the sanction under Section 151 was granted mechanically without proper application of mind. The respondents argued that the rigs constituted a permanent establishment in India and that the income was taxable. The court analyzed the time limits under Section 149 and found that the notices for AY 2014-15 were issued on 31 March 2021, which was beyond the six-year limit for cases involving income escaping assessment of Rs. 1 lakh or more, and beyond the four-year limit for other cases. Since there was no allegation of failure to disclose material facts, the four-year limit applied, and the notices were time-barred. The court also held that the sanction under Section 151 was invalid as the Principal Commissioner did not record satisfaction that it was a fit case for reopening. Consequently, the court quashed the reassessment notices and allowed the petitions.
