Treaty shipping profits under Article 8 extended to feeder vessel slot charters; interest levies under sections 234B and 234D were denied.

Freight income from carriage of cargo through feeder vessels under slot or space charter arrangements was treated as part of the "operation of ships" for Article 8 of the India-Malaysia DTAA, because the charterer concept was read broadly and the feeder movement was commercially inseparable from the onward voyage. Interest under section 234B was held not leviable where the income was subject to tax deduction at source and binding precedent applied. Interest under section 234D was held not chargeable where the original assessment had already been completed under section 143(3) and later reassessment could not be treated as a regular assessment. Interest income was also stated to be taxable at the beneficial treaty rate under Article 11.

Issues: (i) Whether freight income earned from carriage of cargo through feeder vessels under slot or space charter arrangements was eligible for the benefit of Article 8 of the India-Malaysia DTAA as profits from the operation of ships; (ii) whether interest under section 234B of the Income-tax Act, 1961 was leviable on the assessee; (iii) whether interest under section 234D of the Income-tax Act, 1961 was chargeable on the Revenue's appeal; and (iv) whether interest income was taxable at the beneficial rate under Article 11 of the India-Malaysia DTAA.

Analysis: The freight issue turned on the meaning of "operation of ships" in Article 8 of the India-Malaysia DTAA. The Tribunal held that the expression "charterer" is wide enough to include slot charter or space charter arrangements, and that transportation from the Indian port to the hub port through feeder vessels was inextricably linked with the onward carriage by the assessee's own ships. It therefore treated the entire voyage as part of the shipping operation covered by Article 8. On section 234B, the Tribunal noted that the assessee had no advance tax liability where the freight income was subject to tax deduction at source and the issue was covered by binding precedent. On section 234D, it held that where the original assessment had already been completed under section 143(3), subsequent reassessment could not be treated as a regular assessment for charging such interest. On Article 11, the Tribunal accepted that interest income was taxable at the treaty rate applicable to that article.

Conclusion: The freight income from feeder vessel operations qualified for Article 8 relief, interest under section 234B was not leviable, interest under section 234D was not chargeable, and the interest income was assessable at the beneficial treaty rate under Article 11.

Final Conclusion: The assessee obtained substantive relief on the main treaty issue and on the interest-related grounds, while the Revenue's challenge on section 234D failed.

Ratio Decidendi: Under a treaty that defines shipping profits by reference to transportation carried on by an owner, lessee, or charterer, slot or space charter arrangements forming an integral part of a single voyage can fall within the expression "operation of ships" when the carriage is commercially and factually inseparable from the main shipping movement.
