Case Title: Theco India (P.) Ltd. v. Secretary, National Anti-Profiteering Authority
Court: High Court of Madras
Petition No.: W.P. No.15527 of 2020
Date of Judgment: 27 October 2021
Relevant Sections: Section 171 of CGST Act, Rules 126, 128, 129, and 133 of CGST Rules
Category of Dispute: Anti-profiteering – Jurisdiction & Retrospective Operation of Rule 133(5)
Facts of the Case
[Para 1–2] The petitioner, a trader in dental equipment, was accused by a customer of not passing on the benefit of ITC post-GST implementation. The complaint led to an initial order on 28-11-2018 by the NAA directing payment of Rs. 4.78 lakh with interest.
[Para 2(iii)–(iv)] The Authority suspected wider profiteering and directed DGAP to conduct a suo motu investigation across all supplies.
[Para 2(v)] DGAP, in its 12-4-2019 report, expressed doubts on jurisdiction and feasibility. However, NAA reiterated the direction on 1-8-2019 citing powers under Rule 133(5), covering the period from 1-7-2017 to 30-8-2019.
[Para 2(vi)] DGAP concluded in its 1-7-2020 report that Theco India had contravened Section 171(1) of the CGST Act. A notice dated 10-7-2020 followed.
[Para 3] The petitioner challenged the jurisdiction to issue the notice based on retrospective application of Rule 133(5), which was inserted only on 28-6-2019.
Question(s) in Consideration
[Para 10] Whether Rule 133(5)(a) & (b) of the CGST Rules, inserted on 28-6-2019, could be applied retrospectively to complaints and investigations initiated prior to that date.
Observations of the Court
[Para 26–28] The Court noted that DGAP followed proper procedure and provided an opportunity of hearing to the petitioner before issuing its report.
[Para 30–32] Citing the principle that procedural provisions operate retrospectively unless stated otherwise, the Court observed Rule 133(5) only facilitated investigation and was procedural in nature.
[Para 32] The Court rejected the petitioner’s argument that Rule 133(5) imposed substantive new obligations.
[Para 36–40] It drew parallels with judgments under the Competition Act, particularly Excel Crop Care Ltd., holding that procedural expansions intended to aid statutory objectives should not be read restrictively.
[Para 43] The Court held that Section 171, read with Rule 133, enabled authorities to combat profiteering effectively, and procedural empowerment must be interpreted in line with legislative intent.
Judgment of the Court
[Para 44–46]
- The High Court upheld the jurisdiction assumed by the National Anti-profiteering Authority.
- It directed the petitioner to respond to the impugned notice within three weeks and appear before the Authority.
- The petition was dismissed, with liberty granted to both sides to argue the matter afresh before the Authority.
- No costs were awarded.
Between Fine Lines
- Rule 133(5) was held to be procedural and applicable retrospectively.
- Even if a complaint was filed before 28-6-2019, suo motu investigation by NAA was held valid.
- The petitioner must respond to the notice rather than challenge jurisdiction through writ.
- Anti-profiteering provisions are to be interpreted to fulfil their objective, not restrictively.
- Proper process and opportunity of hearing were followed by DGAP and NAA.
