The month’s decisions reveal a GST landscape increasingly shaped by procedural discipline. Courts and tribunals repeatedly returned to a common question: whether statutory power has been exercised through the route, forum, notice, time limit and evidentiary process prescribed by law. In several matters, the result was not a final determination of tax liability but a remand, restoration of an appeal, or a direction to reconsider. Yet these procedural outcomes were not inconsequential. They determined whether a demand could be enforced, whether an appeal could be heard, and whether the taxpayer would receive a meaningful opportunity to answer the case against it.

The Supreme Court’s ruling in Goodluck India Ltd. and Anr. v. Union of India and Ors., (2026) taxcode.in 46 SC, is emblematic of this concern with statutory transition. The Court treated the omission of Rule 96(10) of the CGST Rules, without a saving clause or statutory fiction, as bringing pending proceedings under the omitted rule to an end. In a different setting, Gaurav Jain and Anr. v. Joint Commissioner (Appeals-II) CGST Delhi Zone and Anr., (2026) taxcode.in 1247 HC, and Reddy Veeranna Constructions Pvt. Ltd. v. Appeal I Commissioner Appeal I Commissioner Appeal I Commissioner and Ors., (2026) taxcode.in 75 GSTAT, addressed the temporal operation of new penalty pre-deposit requirements. Both decisions treated the appellate remedy, including its financial conditions, as a legally significant package rather than a purely procedural facility.

At the substantive end, the Gujarat High Court’s decision in Torrent Power Ltd. v. Union of India and Ors., (2026) taxcode.in 1333 HC, presents a more complex balance. The Court upheld the levy of GST on corporate guarantees furnished between related companies, but read down the “whichever is higher” component of Rule 28(2), held that the prescribed valuation could not operate for the period before 26.10.2023, and found the Section 74 proceedings unsustainable in the circumstances. The result illustrates the month’s broader pattern: statutory power may survive while a particular method of valuation, procedure or enforcement does not.

Procedure, notice and the limits of digital administration

Portal-based communication produced sharply contrasting outcomes. The Punjab and Haryana High Court, in a series of decisions including Svam Power Plants Pvt. Ltd. v. Proper Officer, (2026) taxcode.in 1261 HC, Saraswati Wood Products v. Union of India and Ors., (2026) taxcode.in 1263 HC, and Shivam Wood Products v. State of Haryana and Ors., (2026) taxcode.in 1265 HC, applied its earlier view that mere uploading in the “View Additional Notices and Orders” tab did not, by itself, establish sufficient service in the circumstances considered. The Court declined to alter that position merely because of the retrospective amendment relied upon by the Revenue. The remedial consequences included restoration to the show-cause stage or reopening of the appellate route, depending on whether the matter had proceeded ex parte or after contest.

The Calcutta High Court adopted a similar approach in Kajal Sarkar v. Additional Commissioner of Revenue State Goods & Service Tax and Anr., (2026) taxcode.in 1267 HC, where the show-cause notice and order were uploaded in the Additional Notices and Orders tab and the hearing was fixed before the last date for filing a reply. Both the adjudication and appellate orders were set aside. By contrast, in M. M. Motors and Anr. v. Senior Joint Commissioner of Revenue Berhampore Circle WBGST and Ors., (2026) taxcode.in 1232 HC, the Calcutta High Court distinguished “issue” from “service” under Section 73. It held that an order digitally signed within limitation was issued in time even though portal upload occurred the following day.

The contrast is important. The decisions do not establish a single universal answer to every portal dispute. They turn on the statutory distinction between issuance and service, the mode and location of upload, actual participation, the presence or absence of prejudice, and the procedural history of each case. The practical message is equally directed to both sides: authorities must use a legally recognised and intelligible channel, while taxpayers challenging service must plead and establish the precise procedural defect and its effect.

Alternative remedy: restraint, exceptions and calibrated relief

The courts continued to treat the statutory appellate hierarchy as the ordinary route for challenging adjudication orders, particularly where the dispute involved evidence, computation or contested factual matters. In Wizard Digitek Computers Pvt. Ltd. v. Union of India and Ors., (2026) taxcode.in 1297 HC, the Delhi High Court declined to examine objections concerning electronic evidence, forensic material, cross-examination and the effect of an earlier audit because the record showed participation through an authorised representative and a detailed reply. Those objections, the Court held, went to the merits and evidentiary foundation of the order.

Likewise, Bhagwati Electronics v. Union of India and Ors., (2026) taxcode.in 1344 HC, treated differing claims about personal hearing, third-party electronic records, relied-upon documents and alleged coercive deposits as matters requiring individual examination before the appellate authority. The Court was unwilling to treat a common investigation as establishing a common natural-justice violation across all noticees.

Yet alternative remedy remained a rule of judicial discretion, not an absolute jurisdictional bar. In Rathi Cement House v. Union of India and Ors., (2026) taxcode.in 1335 HC, the Calcutta High Court entertained a challenge to a single show-cause notice covering multiple financial years, treated the issue as jurisdictional, and quashed the notice and consequential order. The Gauhati High Court took the opposite view on the same structural question in Gias Uddin Ahmed and Anr. v. Union of India and Ors., (2026) taxcode.in 1326 HC, and North East Petrochemicals v. Union of India and Othrs, (2026) taxcode.in 1396 HC, following its stated precedent that consolidated notices and orders for different financial years were not barred.

The month therefore reinforces a disciplined distinction: a pure jurisdictional defect apparent from the record may justify writ intervention; a disputed question about facts, evidence or the scope of overlapping proceedings ordinarily belongs in appeal. Relief is frequently calibrated through exclusion of time, continuation of interim protection, or liberty to file an appeal, rather than through a final ruling on the underlying tax demand.

Time limits, rectification and the architecture of appellate rights

Limitation emerged as one of the month’s most consequential themes. In Radhika Furniture @Radha Devi v. Commissioner State Goods and Services Tax and Ors., (2026) taxcode.in 1320 HC, the Uttarakhand High Court held that Section 5 of the Limitation Act stood excluded by necessary implication from the Section 107 appellate regime. The Court treated the three-month period and the further one-month condonable period as a self-contained fiscal limitation structure.

The Madras High Court’s decision in E2E Supply Chain Solutions Ltd. v. Deputy Commissioner (ST) GST Appeal Chennai-I and Ors., (2026) taxcode.in 1384 HC, drew a more nuanced distinction. While Section 5 principles could not extend the statutory condonable period, the equitable principles underlying Section 14 could, in appropriate cases, exclude time spent bona fide pursuing a rectification petition. The Court insisted on both due diligence and good faith, and refused automatic exclusion merely because rectification had been filed.

In Kanan International Pvt. Ltd. and Anr. v. Union of India and Ors., (2026) taxcode.in 1390 HC, the Gujarat High Court held that where rectification had been filed within the prescribed period and thereafter decided by a reasoned order, limitation had to be examined from the rectification order rather than mechanically from the original order. The decision was not framed as an unlimited right to reopen limitation; the Appellate Authority retained power to reject the appeal if, after the correct computation, it remained out of time.

The Supreme Court’s ruling in Union of India v. Sunil Biyani, (2026) taxcode.in 49 SC, added a distinct safeguard in the criminal-investigative context. While a court cannot grant interim protection after dismissing a pre-arrest bail application as not maintainable, the Court held that an order under Section 69 authorising arrest must be communicated to the person concerned. The decision links disclosure to the practical ability to seek anticipatory bail and to challenge the reasons underlying the arrest decision.

Section 74, natural justice and the requirement of an evidentiary foundation

A recurring judicial concern was the tendency to invoke the extended machinery of Section 74 through formulaic language. In G.R. Infra Projects Ltd. v. State of Madhya Pradesh and Ors., (2026) taxcode.in 54 SC, the Supreme Court held that the notice itself must disclose the factual basis for fraud, wilful misstatement or suppression. A counter affidavit cannot supply what the notice omitted. The notice was consequently held beyond the Section 73 period and incapable of being rescued by Section 74.

The same insistence appears in Tata Steel Ltd. v. Union of India and Ors., (2026) taxcode.in 56 SC, where the Court held that the Assessing Officer must independently satisfy himself not only about mismatch or short payment but also about the ingredients supporting Section 74. The mere insertion of expressions such as “suppression” or “wilful misrepresentation” was insufficient. The Court set aside the notice and consequential order, while leaving limited liberty to initiate appropriate proceedings if a legally sufficient notice could still be issued within the permissible period.

The GSTAT applied the same logic in Santhome Latex Enterprises v. Commissioner of CGST Thiruvananthapuram, (2026) taxcode.in 95 GSTAT, holding that mere availment of self-assessed ITC, or failure to answer an audit communication, did not establish suppression without evidence of deliberate intent to evade. The appellate authority could not reverse a reasoned adjudication on a new ground absent from the show-cause notice. Similarly, in Commissioner CGST & CX v. Power Tech Global Pvt. Ltd., (2026) taxcode.in 77 GSTAT, the Tribunal held that a 2022 amendment to Rule 43 was prospective, but nevertheless found Section 74 unavailable on the record for want of fraud, wilful misstatement or suppression.

Anti-profiteering: from broad ratios to recipient-specific proof

The anti-profiteering decisions show a regime moving towards closer scrutiny of the actual benefit and the recipient-specific consequence. In the real-estate cases, the GSTAT repeatedly required project-level verification, buyer-wise allocation and documentary support. Director General of Anti-Profiteering (DGAP) v. Maata Rani Builders and Developers, (2026) taxcode.in 69 GSTAT, and Director General of Anti-Profiteering (DGAP) v. MM Construction, (2026) taxcode.in 72 GSTAT, rejected the proposition that free additional construction work or fittings could substitute the statutory requirement of commensurate reduction in price. The decisions treated the prescribed mode of pass-through as legally material, even where the supplier asserted that the economic value of the additional work exceeded the computed benefit.

At the same time, not every investigation resulted in liability. In Director General of Anti-Profiteering (DGAP) v. Bengal Peerless Housing Development Company Ltd. (Other Projects), (2026) taxcode.in 71 GSTAT, the post-GST credit-to-purchase ratio was lower than the pre-GST ratio and no additional ITC benefit was found. Director General of Anti-Profiteering (DGAP) v. Prl Developers, (2026) taxcode.in 73 GSTAT, likewise accepted that the developer had passed on more than the recomputed benefit after the goods component was correctly included in the pre-GST denominator.

The cinema-ticket decisions, including Director General of Anti-Profiteering (DGAP) v. Vimal 70mm Hyderabad, (2026) taxcode.in 85 GSTAT, and Director General of Anti-Profiteering (DGAP) v. Arjun Theatre 70mm, (2026) taxcode.in 84 GSTAT, applied the same logic to a reduction in GST from 18% to 12%. Maintaining the same cum-tax price by increasing the base price was treated as retention, rather than transmission, of the benefit. However, the Tribunal excluded ticket categories supported by the relevant material and limited the computation to the period and transactions actually established.

Transition, classification and the boundaries of statutory power

Several decisions addressed the continuing difficulty of moving between tax regimes. In Tata Unistore Ltd. v. Commissioner CGST & Ex. and Ors., (2026) taxcode.in 76 GSTAT, the Tribunal held that GST authorities could not use CGST proceedings to reassess the eligibility of credit originally availed under the erstwhile regime where that credit had not been challenged under the earlier law. In Shakti Enterprises v. Principal Commissioner of Central Tax GST Commissionerate, (2026) taxcode.in 1351 HC, the Karnataka High Court held that transitioned CENVAT credit could be used to satisfy a legacy pre-deposit where the statute did not require cash payment exclusively.

Classification decisions showed the importance of the actual character of the supply. The Karnataka AAR in Karam Chand Thapar & Bros (Coal Sales) Ltd., (2026) taxcode.in 22 AAARGST, treated loading ballast into railway wagons as an independent cargo-handling service rather than a works contract or composite supply. The Gujarat AAR’s decisions in In re: Rashmiben Sanjaykumar Hemani (Trade Name: Galaxe Prints), (2026) taxcode.in 131 AARGST, and In re: Lab Medica Systems Pvt. Ltd., (2026) taxcode.in 129 AARGST, applied the tariff descriptions and the functional use of the goods rather than the commercial labels proposed by the applicants.

The month also produced firm limits on enforcement powers. In S. Muthukumar v. State Tax Officer, (2026) taxcode.in 1259 HC, a conditional remand was granted despite the Court rejecting the taxpayer’s explanation for non-response. In Mohd Hazzak Lohar and Anr. v. Commissioner State Tax and Anr., (2026) taxcode.in 1358 HC, the seven-day limit for passing a Section 129 penalty order was treated as mandatory, even though the delay was only one day and intervening circumstances were relied upon.

Key Decisions of the Month

Goodluck India Ltd. and Anr. v. Union of India and Ors., (2026) taxcode.in 46 SC, deserves priority reading for its treatment of an omitted rule and pending proceedings. Its immediate subject was Rule 96(10), but its significance lies in the Court’s insistence that continuation after omission requires a saving clause or statutory fiction.

Gaurav Jain and Anr. v. Joint Commissioner (Appeals-II) CGST Delhi Zone and Anr., (2026) taxcode.in 1247 HC, is central for practitioners dealing with penalty-only appeals and the substituted Section 107(6) pre-deposit requirement. The High Court allowed the appeals to be filed without the new ten per cent deposit because the adjudicatory lis had commenced before the amendment. The merits of the penalties were expressly left open.

Torrent Power Ltd. v. Union of India and Ors., (2026) taxcode.in 1333 HC, merits close attention for its layered treatment of corporate guarantees. The Court upheld taxability as a related-party supply of service, but read down the valuation formula, restricted its temporal operation and quashed Section 74 action in the circumstances presented.

G.R. Infra Projects Ltd. v. State of Madhya Pradesh and Ors., (2026) taxcode.in 54 SC, and Tata Steel Ltd. v. Union of India and Ors., (2026) taxcode.in 56 SC, should be read together. They underline that extended limitation under Section 74 cannot be secured by incanting statutory expressions; the notice must contain the factual foundation and reflect the officer’s independent satisfaction.

For anti-profiteering work, Director General of Anti-Profiteering (DGAP) v. Maata Rani Builders and Developers, (2026) taxcode.in 69 GSTAT, and Director General of Anti-Profiteering (DGAP) v. Prl Developers, (2026) taxcode.in 73 GSTAT, are particularly useful. Read together, they show both sides of the inquiry: the prescribed mode of price reduction remains important, but liability must still rest on a verified and correctly constructed computation.

Closing Editorial Note

The month’s case law does not speak with one voice on every procedural question, particularly in the digital-service and limitation fields. Its more consistent message lies elsewhere: statutory power must be exercised with precision. A notice must disclose the case; an appellate condition must have the temporal reach the law gives it; an extended limitation period requires facts, not formula; and a procedural remedy cannot be used to convert a provisional or defective exercise into a final liability. For practitioners, the decisive work remains close reading of the record—what was issued, when it was issued, what was communicated, what was pleaded, what was proved, and what the authority actually decided.
