Court rules income of foreign technician on rigs beyond territorial waters not taxable under Income-tax Act pre-extension

The court ruled in favor of the assessee, holding that income earned by a foreign technician on rigs beyond territorial waters of India before the notification extending the Income-tax Act's applicability to the continental shelf and economic zone was not taxable. The court emphasized that income must accrue in a territory where the Act applies to be taxable, distinguishing legislative amendments from notifications. The judgments of the Madras High Court and Bombay High Court supported this interpretation, leading to a decision against the Department and in favor of the assessee, with all related appeals disposed of without costs.

Issues:
Taxability of income earned by a foreign technician on rigs located in the continental shelf and economic zone beyond territorial waters of India during the accounting year ending March 31, 1983. Interpretation of the applicability of the Income-tax Act to the exclusive economic zone and continental shelf before and after a specific notification.

Analysis:
The case involved a dispute over the taxability of income earned by an employee on an offshore drilling rig beyond 12 nautical miles during the assessment year 1983-84. The Assessing Officer held the income as taxable based on a notification issued by the Government of India on March 31, 1983, making the Income-tax Act applicable to the continental shelf and exclusive economic zone from April 1, 1983. The Department contended that the continental shelf was part of India even before the notification, and thus, the income earned before April 1, 1983, was taxable. The Tribunal, however, ruled in favor of the assessee, stating that the income accrued outside the taxable territory before the notification was not chargeable to tax. The High Court concurred with the Tribunal's decision, emphasizing that the income must accrue in a territory where the Income-tax Act applies for it to be taxable. The court highlighted that the notification specifically extended the Act's applicability to the continental shelf and economic zone from April 1, 1983, making income earned before this date non-taxable. The judgments of the Madras High Court and Bombay High Court were cited to support this interpretation, distinguishing cases where amendments to the Income-tax Act were made through legislative acts, unlike the present case where only a notification under a different Act was issued.

The court's analysis focused on the concept of the taxable territory of India under the Income-tax Act, emphasizing that the income in question must accrue in a territory where the Act applies to be taxable. The notification issued on March 31, 1983, extended the Act's applicability to the continental shelf and exclusive economic zone from April 1, 1983, making it clear that income earned before this date in those areas was not taxable. The court highlighted the distinction between legislative amendments to the Income-tax Act and notifications issued under different Acts, emphasizing that the present case involved the latter. The judgments cited supported the view that income earned before the extension of the Act's applicability to certain territories was not subject to taxation for the relevant assessment year. Consequently, the court answered both questions in favor of the assessee and against the Department, disposing of all related appeals without costs.
