Liberal condonation of delay restored the main income-tax appeal on merits, rendering the connected rectification challenge infructuous.

Delay in filing an appeal against an intimation under section 143(1) was condoned because the explanation showed sufficient cause, with the period spent in rectification proceedings treated as a valid reason and the liberal approach to substantial justice applied. The first appellate authority's order rejecting the matter on limitation was set aside and the appeal was restored for decision on merits. Once the main appeal was revived, the connected challenge to the rectification order under section 154 ceased to have independent practical survival and was dismissed as infructuous.

Issues: (i) Whether the delay in filing the appeal against the intimation under section 143(1) of the Income-tax Act, 1961, should be condoned and the matter restored to the first appellate authority for decision on merits. (ii) Whether the appeal against the rectification order under section 154 of the Income-tax Act, 1961, survived independently after restoration of the main appeal.

Issue (i): Whether the delay in filing the appeal against the intimation under section 143(1) of the Income-tax Act, 1961, should be condoned and the matter restored to the first appellate authority for decision on merits.

Analysis: The delay was explained as arising from pursuit of rectification proceedings and the time consumed in that process. The governing principle applied was that "sufficient cause" for condonation must receive a liberal construction to advance substantial justice, and that length of delay is not decisive where the explanation is acceptable. The appellate order had rejected the appeal on limitation without examining the merits.

Conclusion: The delay was condoned, the order of the first appellate authority was set aside, and the matter was restored for decision on merits; the assessee obtained relief on this issue.

Issue (ii): Whether the appeal against the rectification order under section 154 of the Income-tax Act, 1961, survived independently after restoration of the main appeal.

Analysis: Once the appeal against the intimation was restored for merits-based adjudication, the challenge to the rectification order ceased to have independent practical survival, as it was consequential to the main appeal.

Conclusion: The appeal against the rectification order was dismissed as infructuous, against the assessee.

Final Conclusion: The matter was sent back for merits-based consideration in the main appeal, while the connected appeal was disposed of as infructuous.

Ratio Decidendi: A delay in filing an appeal may be condoned where the explanation shows sufficient cause and the interest of substantial justice warrants restoration, and a consequential challenge becomes infructuous once the principal matter is revived for fresh adjudication.
