Anti-profiteering re-investigation may use corrected project-wide methodology, requiring input tax credit benefits to reach eligible homebuyers.
Anti-profiteering re-investigation may validly follow a remand to apply a project-wide, per-square-foot apportionment of GST savings where an earlier methodology was legally unsustainable. The original reference remains operative, and the investigating authority is not functus officio where no final adjudicatory order followed the flawed report. Rule 129(6)'s reporting period is directory rather than mandatory, and delay arising from non-production of records does not bar re-investigation. Re-investigation does not breach natural justice where notice, access to the report, and opportunities for objections are provided. Section 171(1) requires suppliers to prove actual transmission of input tax credit benefits through commensurate price reduction; unpassed benefits attract interest, while no penalty applies for periods before the penalty provision took effect.
Issues: (i) Whether the re-investigation was void ab initio for want of jurisdiction; (ii) Whether the investigative authority was functus officio and a fresh Standing Committee reference was required before re-investigation; (iii) Whether the re-investigation was barred by limitation under Rule 129(6), including the validity of the extension; (iv) Whether the revised methodology and re-investigation denied the respondent natural justice; (v) Whether failure to pass on the additional input tax credit benefit contravened Section 171(1), and the consequential relief.
Issue (i): Whether the re-investigation was void ab initio for want of jurisdiction.
Analysis: A binding jurisdictional precedent found the earlier real-estate profiteering methodology legally unsustainable because input tax credit and buyer collections do not correlate uniformly during a project's life cycle. The applicable methodology requires project-wide GST savings to be apportioned across the total saleable area on a per-square-foot basis. Remitting pending matters to correct that legal infirmity ensured conformity with binding precedent and did not amount to an impermissible review of a concluded adjudication. No fundamental statutory prohibition or jurisdictional defect was established.
Conclusion: The re-investigation was valid and was not void ab initio, against the respondent.
Issue (ii): Whether the investigative authority was functus officio and a fresh Standing Committee reference was required before re-investigation.
Analysis: The doctrine of functus officio did not apply because the original report, founded on a flawed methodology, had not culminated in a final adjudicatory order. Rule 133(4) permitted remand for re-investigation, while the original reference under Rule 128 remained operative. The fresh exercise was undertaken pursuant to remand within the same proceedings rather than through a suo motu reopening.
Conclusion: The investigative authority was not functus officio, and no fresh Standing Committee reference was required, against the respondent.
Issue (iii): Whether the re-investigation was barred by limitation under Rule 129(6), including the validity of the extension.
Analysis: Rule 129(6) does not prescribe a consequence of abatement upon expiry of the reporting period. Its time limit is directory, not mandatory, particularly having regard to the beneficial and consumer-welfare character of the anti-profiteering framework. Complete documents were furnished only in August 2025, and the respondent could not rely on delay attributable to its own non-production of records.
Conclusion: The re-investigation was not barred by limitation, and the extension was valid, against the respondent.
Issue (iv): Whether the revised methodology and re-investigation denied the respondent natural justice.
Analysis: The revised methodology followed binding law and was not an arbitrary alteration of standards. Notice of re-investigation, an opportunity to supply documents, service of the report, and repeated opportunities to file objections were provided. The respondent elected to confine its defence to preliminary objections and did not contest the computation on merits.
Conclusion: There was no violation of the principles of natural justice, against the respondent.
Issue (v): Whether failure to pass on the additional input tax credit benefit contravened Section 171(1), and the consequential relief.
Analysis: Section 171(1) requires actual transmission of input tax credit benefit through commensurate reduction in price and is a beneficial provision requiring purposive construction. Once records establish an accrued benefit, the evidential burden lies on the supplier to show that it was passed on. The uncontroverted computation showed an increase in credit ratio from 2.37% to 8.42%, producing a per-square-foot benefit of Rs. 40.33 and an aggregate unpassed benefit of Rs. 31,20,542 for 66 eligible homebuyers. No evidence of price reduction, adjustment, credit note, refund, or other transmission of the benefit was produced. The contravention period ended before Section 171(3A) came into force.
Conclusion: The respondent contravened Section 171(1) by failing to pass on Rs. 31,20,542 to 66 eligible homebuyers; the amount is payable with interest at 18% per annum, and no penalty is imposable.
Final Conclusion: The remand and corrected project-wide methodology were sustained, and the additional input tax credit saving was required to be restored to the eligible homebuyers with interest; the pre-effective-date period excluded penal liability.
