Section 127 transfer power is a machinery provision requiring a demonstrated, legitimate need for coordinated investigation. Alleged accommodation entries alone do not establish the necessary nexus; the Revenue must show structural links with the searched group, interlacing of funds, or interconnected business activities. An isolated banking transaction and an opaque factual basis indicate inadequate application of mind and disproportionate operational prejudice, rendering an inter-State jurisdictional transfer legally untenable.

Demand adjudication cannot disregard a reply uploaded in Form GST DRC-06 and proceed ex parte on the incorrect basis that no reply was filed. Consideration of the response, an effective personal hearing, and a reasoned decision are required; the demand must therefore undergo fresh adjudication. Negative blocking of the Electronic Credit Ledger under Rule 86A(1) cannot be used as a recovery mechanism for allegedly wrongful or ineligible input tax credit. Questions concerning return filing, registration cancellation, and ledger operability must be determined through the applicable statutory process.

Statutory appellate remedy before the GST Appellate Tribunal becomes available once the Tribunal is functional, even where a writ petition was instituted during its non-constitution. A petitioner may pursue the statutory appeal within the permitted period, with the time spent in writ proceedings considered by the Tribunal, subject to statutory compliance. This enables transition from writ proceedings to the ordinary appellate mechanism after the appellate forum becomes operational.

Section 83 permits provisional attachment only after qualifying proceedings commence, against property belonging to a taxable person or person covered by Section 122(1-A), where tangible material establishes that attachment is necessary to protect revenue. The power requires a live nexus between the material and necessity, and must satisfy proportionality; vague suspicions involving third-party money laundering or online gaming do not suffice. Attachment reasons cannot be supplemented by affidavit. Merchant settlement funds held in escrow under a trust are not the payment aggregator's attachable property. As no GST liability, identified transactions, evasion mechanism, or statutory coverage was established, the attachment and remaining debit-freeze restrictions were set aside.

Provisional attachment of a payment aggregator's current and regulated escrow accounts requires an opinion based on tangible material showing that attachment is necessary to protect revenue. Vague suspicion of GST evasion by unidentified third-party online gaming merchants, without identifying the aggregator's tax liability, relevant transactions, evasion method, or statutory status, does not satisfy that threshold. Escrow funds reserved for merchant settlements are held in trust and are not the aggregator's attachable property. The High Court treated the attachment orders and continuing debit freezes as illegal and quashed them.

Inter-State transfer of assessment jurisdiction for coordinated investigation requires a demonstrated structural nexus between the taxpayer and the searched group; an isolated transaction is insufficient. Alleged incriminating material must establish interlacing of funds or interconnected business activities, rather than an unfounded or non-transparent conclusion. Absent a legitimate necessity for coordinated investigation, transfer may be arbitrary, show non-application of mind, and breach natural justice. Assessment jurisdiction remained at Kolkata, while material gathered at New Delhi was to be sent to the Kolkata Assessing Officer for lawful inquiry, preserving the Revenue's ability to investigate there.

Service of a seizure order in Form GST INS-02 was satisfied where the order identified the seized articles and bore the petitioner's signatures acknowledging physical delivery. The High Court declined to resolve conflicting factual claims on affidavits in writ jurisdiction, rejected the non-service challenge to the search and seizure proceedings, and dismissed the writ petition. The merits of the statutory proceedings remained open before the competent authority.

Input tax credit may remain available to a bona fide purchasing dealer where contemporaneous records, including tax invoices, e-way bills, consignment notes, banking payment evidence and proof of material consumption, establish actual receipt and use of goods. A supplier's later non-existence or retrospective registration cancellation does not by itself defeat credit if the supplier was registered when the supply occurred and transaction evidence remains unrebutted. Penalty for wrongful credit requires proof of fraud, wilful misstatement, suppression or collusion attributable to the recipient; a purchaser is not a guarantor of the supplier's subsequent non-compliance.

E-way bill rules require an e-way bill for internal stock transfers exceeding the prescribed value, even where goods move under a delivery challan otherwise than by supply; the challan does not replace that obligation. Transfer of tax-paid goods between a dealer's own premises, without another person or consideration, does not constitute supply and attracts no tax. Although failure to carry an e-way bill was a technical procedural breach, penalty under Section 129 was unsustainable because the goods were traceable and a bona fide misunderstanding of distance-based rules negated intent to evade tax. The penalty and related orders were set aside, with refund of the deposited penalty plus applicable interest.

Ghamella/Tasla is classified as a taxable article under the specific Chapter 73 tariff description rather than as an exempt agricultural hand tool. Its concave, load-bearing container design lacks the active working attributes of a hand tool, so the specific entry prevails over the general exemption entry. The later exclusion from the agricultural-tools exemption is clarificatory and does not create retrospective tax liability. Internal audit clearance or pre-notice administrative closure is not a quasi-judicial adjudication and does not bar a subsequent show cause notice on res judicata grounds. Describing the unchanged product as an exempt implement supports penalty for deliberate misstatement and suppression of taxable supplies.

Penalty under Section 129(3) for alleged diversion of goods requires reliable evidence that the actual movement or delivery contravened GST law, even where valid invoices and e-way bills accompany the consignment. Vehicle proximity to another factory, discrepancies in a transport bilty, and the driver's statement do not, without corroboration, establish delivery to an undeclared recipient where the goods' description and quantity match the accompanying documents. Failure to provide GPS-camera footage relied on adversely may deny a fair opportunity to contest the allegation. The penalty orders were set aside and the penalty quashed.

Refund of accumulated Compensation Cess ITC for domestic leather-product supplies under the inverted-duty structure requires more than lawful availment of credit. Section 54(3) limits refunds of unutilised ITC to statutory categories; credit usable only for Compensation Cess does not itself establish a cash-refund right. The claimant must meet the inverted-duty test and show that the exclusion for nil-rated or exempt outward supplies does not apply. A clarification on qualifying zero-rated supplies does not create an unconditional domestic-supply refund. As statutory entitlement was not established, the refund-granting order was set aside and rejection orders restored.

Customs and food-safety legislation operate concurrently: border control, tariff classification, valuation and anti-fraud enforcement remain within Customs powers, while food-safety compliance is regulated separately. A Customs Proper Officer may draw samples of imported food before Bill of Entry routing through FICS for Customs examination and investigation; routine FSSAI sampling does not create exclusive jurisdiction. Executive instructions cannot restrict statutory Customs powers. Challenges to sampling, testing methods, chain of custody and laboratory-report admissibility should be resolved in show-cause adjudication. Judicial review should not prematurely quash those processes or impose fresh-sampling, testing, cargo-release, or charge-waiver directions beyond the writ relief sought.

Delayed production of invoices and bilties did not establish that intercepted makeup accessories were documented, where the driver initially produced all documents available and the later material was uncorroborated. Unidentified buyers and sellers, unverified business credentials, unexplained discrepancies, and no reliable link between the documents and goods supported treating the consignment as undeclared. Transit-State action was not excluded by the asserted inter-State movement because the claimed out-of-State destination was not established. The documented-consignment precedent was distinguishable, and the penalty for transporting undeclared goods was sustained.

Refund of accumulated Compensation Cess input tax credit on coal used to manufacture leather products for domestic supply under an inverted tax structure depends independently on the conditions in Section 54(3); credit standing in the electronic credit ledger does not itself create a cash-refund right. Availability of credit, including the absence of a blocked-credit restriction, concerns credit availment rather than refund eligibility. Inability to use cess credit against other liabilities and the absence of cess on domestic output supplies do not establish inverted tax structure eligibility. Clarifications and export-related decisions concerning zero-rated supplies do not support the domestic refund claim. The refund-granting appellate order was set aside, restoring the original rejections.

Refund of accumulated Compensation Cess input tax credit on coal used to manufacture domestically supplied leather products is limited to the statutory categories for unutilised credit. A cess burden on inputs, where domestic outward supplies do not attract the cess, does not by itself meet the inverted tax structure requirement. Eligibility to avail credit, including the absence of a blocked-credit restriction, is distinct from entitlement to a cash refund. Restrictions on credit utilisation neither bar every refund nor create an independent refund right. Clarifications and authorities concerning zero-rated supplies or exports do not establish eligibility for domestic supplies.

Section 129(1)(a) of the GST Act treats transportation in contravention of the Act or Rules, including movement after expiry of an e-way bill, as attracting civil penalty without requiring proof of intent to evade tax. A claimed vehicle breakdown must be established by reliable material. GPS data concerning another vehicle, repair records lacking evidentiary value, and an explanation not contemporaneously disclosed do not substantiate the claim. Guidance that does not address movement with an expired e-way bill provides no justification; on these facts, the penalty was upheld.

Road-restoration charges paid for planned restoration following road cutting for a business pipeline constitute consideration for a taxable service where the work is specifically requested and involves bilateral reciprocity, rather than compensatory damages. Targeted restoration undertaken for a commercial entity does not qualify as a general governmental public-function service or non-supply, and recipient-side reverse-charge liability applies where forward-charge payment is unproven. Refund sanctions for parallel registrations in other jurisdictions neither bind an independent appellate authority nor override statutory conditions. Electronic GST proceedings remain valid without a physical Document Identification Number where authenticated portal records establish source and integrity, the notice identifies the factual and legal basis, and no prejudice is shown.

Refund adjustment against a disputed penalty demand pending first appeal is ordinarily limited to 20% under CBDT stay guidelines. The guidelines do not distinguish assessment demands from penalty demands, so full adjustment before pending stay applications are decided conflicts with those instructions. Recovery should therefore be confined to 20% of the disputed penalty demand, with excess adjustment reversed and refunded with applicable interest and the balance demand stayed pending disposal of the first appeal.

Revisional limitation for a Debenture Redemption Reserve adjustment to book profit runs from the original assessment where reassessment was initiated on unrelated financial transactions. The High Court held that the original assessment continues to govern matters not forming part of reassessment, while the reassessment order supersedes it only for reassessed items. Although Explanation 3 permits assessment of another escaped-income issue noticed during reassessment, the DRR issue was not shown to have arisen then. The revisional order was therefore time-barred and set aside; the merits of the DRR adjustment remained open.
