Slot charter and feeder vessel income may qualify for treaty shipping relief when international traffic linkage is proved; unsupported voyages may fall under domestic tax rules.

Article 8 of the India-Singapore DTAA was interpreted to cover profits from ships in international traffic and activities directly connected with such transport, including slot charter and feeder vessel operations where the cargo movement was factually linked to the relevant hubs and onward carriage. Treaty protection was held available for voyages supported by evidence, subject to verification by the Assessing Officer. For voyages lacking supporting documents, treaty benefit was declined on the existing material and domestic taxation under section 44B of the Income-tax Act was directed to apply to those unsupported voyages.

Issues: (i) Whether slot charter / feeder vessel operations fell within Article 8 of the India Singapore DTAA so as to entitle the assessee to treaty protection on the shipping income; (ii) whether the unsubstantiated voyages were to be dealt with under section 44B of the Income-tax Act, 1961.

Issue (i): Whether slot charter / feeder vessel operations fell within Article 8 of the India Singapore DTAA so as to entitle the assessee to treaty protection on the shipping income.

Analysis: Article 8 of the India Singapore DTAA was construed with reference to its own language, which covers profits from the operation of ships in international traffic and extends to activities directly connected with such transportation. The expression "international traffic" in the treaty definition and the commercial character of the assessee's slot arrangements were examined in the light of maritime usage. The Tribunal held that a slot charter can be treated as a charter in the relevant commercial sense and that the feeder operations, on the facts, could fall within the treaty wording when the cargo movement was linked to the Singapore and Sri Lanka hubs and onward transport.

Conclusion: The assessee was held entitled to treaty consideration under Article 8 for the voyages supported by evidence, subject to verification by the Assessing Officer.

Issue (ii): Whether the unsubstantiated voyages were to be dealt with under section 44B of the Income-tax Act, 1961.

Analysis: For voyages where supporting documents were not produced, the Tribunal declined to grant treaty benefit on the existing material and directed the Assessing Officer to examine the matter under the domestic shipping provision. The direction was confined to the unsupported voyages and was made as an alternative treatment where Article 8 protection could not be established on evidence.

Conclusion: Section 44B was directed to be applied to the unsupported voyages.

Final Conclusion: The appeals were disposed of with verification-oriented relief on the treaty issue and alternative domestic-tax treatment for the unsupported voyages, resulting in remand for limited examination.

Ratio Decidendi: Where a tax treaty defines shipping profits broadly to include activities directly connected with transportation, slot charter and feeder operations may qualify for treaty benefit if the factual linkage to international traffic is established; absent supporting evidence, domestic shipping taxation may be applied.
