Rectification jurisdiction under section 154 fails where the alleged error is debatable, not an apparent mistake from the record.

Rectification under section 154 is confined to mistakes apparent from the record, meaning an error must be obvious, patent, and self-evident. Where the alleged error depends on a debatable question of law or fact, such as entitlement to dividend tax credit and grossing up in the case of a registered firm, the Income-tax Officer cannot assume jurisdiction under that provision. The existence of an apparent mistake is itself a jurisdictional fact, and the officer cannot create jurisdiction by deciding the issue in his own favour. The availability of an appellate remedy does not cure the absence of jurisdiction. The rectification notice was therefore without jurisdiction and was quashed.

Issues: Whether the Income-tax Officer had jurisdiction to issue a notice under section 154 of the Income-tax Act, 1961, on the footing that there was a mistake apparent from the record in the assessee's assessment relating to dividend tax credit and grossing up.

Analysis: The rectification power under section 154 is confined to mistakes apparent from the record, and that jurisdiction exists only where the alleged error is obvious, patent, and self-evident. A question that requires investigation of competing legal views, or involves a difficult and debatable issue such as the entitlement to dividend tax credit where the assessee is a registered firm and the income of the firm or its partners is claimed to be exempt, cannot be treated as a mere clerical or apparent mistake. The existence of an apparent mistake is a jurisdictional fact, and the Income-tax Officer cannot assume jurisdiction under section 154 by deciding that question in his own favour. The availability of an appellate remedy does not cure the absence of jurisdiction where the very initiation of rectification proceedings is challenged.

Conclusion: The notice under section 154 was without jurisdiction and could not be sustained; the challenge succeeded in favour of the petitioner.

Final Conclusion: The impugned rectification proceedings were quashed and further action pursuant to the notice was prohibited.

Ratio Decidendi: Rectification under section 154 can be invoked only for a mistake apparent from the record, and where the alleged error turns on a debatable question of law or fact, the authority lacks jurisdiction to proceed under that provision.
