Reasonable cause and penalty findings can bar prosecution under tax deduction defaults when the explanation is finally accepted on merits.

Where the competent income-tax authority, acting on merits, accepts the assessee's explanation and deletes penalty for the same tax-deduction default, prosecution under section 276B cannot validly continue for that default. The decision treats the departmental finding as removing the basis for criminal liability, consistent with the principle applied in Uttam Chand. The 1986 amendment to section 276B and the insertion of section 278AA did not alter that position, because section 278AA preserves the defence of reasonable cause and the amended scheme remains consistent with quashing prosecution where the statutory authority has finally accepted the explanation on merits.

Issues: (i) Whether a criminal prosecution under section 276B of the Income-tax Act, 1961 can continue after the statutory revisional authority has, on merits, deleted the penalty for the same default by accepting the assessee's explanation. (ii) Whether the 1986 amendment to section 276B and the insertion of section 278AA alter that position.

Issue (i): Whether a criminal prosecution under section 276B of the Income-tax Act, 1961 can continue after the statutory revisional authority has, on merits, deleted the penalty for the same default by accepting the assessee's explanation.

Analysis: The statutory scheme treated failure to deduct and pay tax at source as giving rise to separate consequences, including interest, penalty, and prosecution. The penalty provisions turned on whether the default was for good and sufficient reasons, while prosecution under section 276B depended on failure without reasonable cause or excuse. Where the competent income-tax authority, acting on merits, accepted the assessee's explanation and deleted the penalty for the same default, the finding rebutted the basis for continuing prosecution for that very default. The earlier decision of the Supreme Court in Uttam Chand was treated as laying down that once the departmental authority has finally decided the issue in favour of the assessee on merits, the prosecution should not continue.

Conclusion: The prosecution could not validly continue and was liable to be quashed.

Issue (ii): Whether the 1986 amendment to section 276B and the insertion of section 278AA alter that position.

Analysis: The omission of the words requiring absence of reasonable cause from section 276B and the insertion of section 278AA did not change the underlying principle. Section 278AA preserved the defence of reasonable cause, and the court held that a prior final order on merits in favour of the assessee under the Act effectively displaced the basis for criminal liability for the same default. The amendment was therefore treated as consistent with, rather than contrary to, the earlier principle that prosecution should not proceed where the statutory authority had finally accepted the explanation on merits.

Conclusion: The amendment did not prevent quashing of the prosecution.

Final Conclusion: The impugned refusal to discharge the petitioners was set aside and the criminal proceeding was quashed as an abuse of the process of court.

Ratio Decidendi: Where the competent authority under the Income-tax Act finally accepts the assessee's explanation on merits and deletes the penalty for the same default, criminal prosecution for that default under section 276B cannot be continued, and the 1986 amendment does not alter that result.
