Under the Uttar Pradesh GST Act, the monetary-limit policy for departmental litigation binds the Department. For GSTAT appeals, the prescribed threshold applies unless a specified exception is established. Commissioner authorisation to file an application does not override that policy. Where the disputed amount falls below the threshold, a departmental appeal is not maintainable unless the Department specifically pleads and proves a recognised exception, including a recorded case-specific opinion under the residual exception.

Tax and penalty demands under Section 74 based on an allegation that a registered firm is bogus or non-existent require proof of tax evasion. A valid GSTIN, identifiable business premises, and filing of GSTR-1 and GSTR-3B for the relevant period supported the firm's registered taxable status. The absence of goods at the premises during verification, without evidence that the firm was non-existent or had evaded tax, did not substantiate the allegation. The tax and penalty demand was therefore unsustainable.

Departmental GST appeals before GSTAT must comply with the binding monetary-limit policy issued under the Uttar Pradesh GST Act. Where the dispute concerns only penalty, the disputed penalty is the relevant amount for applying the prescribed threshold. The Revenue must specifically plead and establish a listed exception to maintain an appeal below that threshold. Statutory authorisation to institute an application does not itself displace the monetary-limit requirement or prove an exception. In the absence of evidence of a specified exception or a recorded Commissioner opinion under the residual exception, the appeal is not maintainable for merits adjudication.

Credit notes reduce taxable turnover under section 34 only when validly issued and declared within the statutory time limit. For inverted-duty-structure refund calculations under Rule 89(5), credit notes relating to supplies in the relevant refund period may reduce adjusted total turnover. Credit notes connected with earlier financial-year invoices but issued after the applicable declaration deadline cannot be excluded from adjusted total turnover. Refund eligibility must therefore be calculated without reducing turnover for those time-barred credit notes, and any resulting excess refund is recoverable.

Credit notes issued for returned, rejected, or reduced-value supplies reduce taxable turnover and may be deducted from adjusted total turnover under the accumulated input tax credit refund formula. Deduction is available where credit notes relate to invoices within the refund period. Credit notes issued during that period but relating to invoices from an earlier financial year cannot reduce adjusted total turnover if issued after the statutory deadline for declaring them. After excluding those belated notes, the recomputed maximum refund still exceeded the refund claimed, leaving the claim admissible.

Retrospective upward price revisions for pre-GST clearances determine the goods' true value at original clearance. The transitional reporting mechanism for post-GST debit notes enables declaration and payment of differential tax but neither creates a new taxable event nor shifts the original time of supply. Interest attaches to delayed payment of differential tax from the original clearance period. Where contractual price escalation creates a bona fide transitional interpretative dispute and tax is voluntarily paid without fraud, wilful misstatement, suppression, or deliberate non-compliance, penal consequences are unwarranted.

Assignment of leasehold rights in an industrial plot and building for consideration transfers the benefits of immovable property to the assignee, who replaces the original lessee. Under section 7(1)(a), Schedule II clause 5(b), and Schedule III clause 5 of the CGST Act, the assignment is not taxable as a supply of services. Its classification as other miscellaneous services under Serial No. 35 of Notification No. 11/2017-Central Tax (Rate) is inapplicable. The jurisdictional ruling excluding these transactions from GST remains binding unless stayed or recalled; consequently, GST is not leviable.

For 2017-18, Section 34 governed reduction of a supplier's output tax liability and did not require a recipient to reverse input tax credit merely on receiving supplier credit notes. Rule 37 applied only where consideration and tax remained unpaid for 180 days, and the matching mechanism was not operational. Excess IGST paid through the electronic credit ledger could be corrected against CGST and SGST liabilities on a net basis where negative GSTR-3B entries were unavailable. Although head-wise adjustment was procedurally irregular, no recoverable short payment arose where refund and re-credit would have restored IGST credit for lawful utilisation and caused no revenue loss.

Where GST registration was cancelled before issuance of a show-cause notice, portal-only service may not provide effective notice because the noticee may be unable or not required to access the Common Portal. Binding departmental instructions requiring physical service in those circumstances apply. Absence of physical service deprives the noticee of an effective opportunity to respond and renders an ex parte adjudication unsustainable. The matter requires fresh adjudication after permitting a reply, necessary requests for documents or cross-examination, and adequate prior notice of personal hearing.

Ex parte cancellation of GST registration without recorded reasons warranted writ intervention under Article 226. The cancellation order was quashed and set aside, with fifteen days granted for filing pending returns and depositing outstanding dues. Absence of reasons in the cancellation order was the central legal defect requiring corrective relief.

Article 226 writ jurisdiction remains available despite an alternative statutory remedy where adjudication breaches procedural fairness and audi alteram partem. Section 74(9) requires consideration of the taxpayer's representation before liability is determined. Rule 142(4) requires a reply in Form GST DRC-06 but does not make electronic filing the exclusive mode: an acknowledged manually filed reply cannot be disregarded solely because it was not uploaded on the portal. Failure to consider that reply, objections, and documents permitted for submission before the allowed time expires violates natural justice, vitiates the adjudication, and requires reconsideration after an effective hearing.

Where GST registration has been cancelled and business operations have ceased, solely uploading a show-cause notice on the GST portal does not constitute adequate service for proceedings under Section 74 of the Uttar Pradesh GST Act. Notice must be issued through an alternative mode consistent with principles of natural justice. Failure to provide effective notice invalidates the resulting Section 74 order and warrants its setting aside for breach of natural justice.

Statutory appellate remedy was permitted despite expiry of the prescribed limitation period and the period capable of condonation. The petitioner received liberty to file an appeal within two weeks. The appeal was to be entertained without any objection based on limitation, enabling recourse to the statutory appellate process notwithstanding the expired time limits.

Excise-duty demand requiring cash payment under Rule 8(3A) of the Central Excise Rules, 2002 was unsustainable because that rule had been declared ultra vires and unconstitutional. Jurisdictional High Court and Tribunal decisions followed that position. Judicial discipline required adherence to those binding decisions, preventing enforcement of the cash-payment requirement through the demand.

Mobile-phone parts classification under Rule 1 of the General Rules for Interpretation and Section XVI Note 2(b) covers specially designed aluminium plates, magnesium alloy sheets, thermal-management materials, antennae, tape and dust-proof paper where they are solely or principally used in mobile-phone manufacture. Further machining, stamping or lamination does not alter that character. These goods qualify for the manufacture-linked customs exemption where their prescribed end use in intermediary or finished mobile phones is established and verified. Low-viscosity polymer granules introduced after filing fall outside the advance-ruling scope because they were not identified in the original application.

Interest-free advances to wholly owned subsidiaries, used for overseas business expansion as owners' quasi-equity and not funded by domestic borrowings, were not benchmarked as ordinary loans for a notional-interest transfer-pricing adjustment; the adjustment was deleted. Corporate-guarantee pricing was restricted to 0.5%, reflecting an arm's-length rate materially lower than a bank-guarantee rate. A creditor's write-off supported an addition for remission or cessation of the related trading liability, while a separate alleged liability required verification of whether it remained outstanding in the taxpayer's books. Only the established write-off addition survived, subject to verification of the other liability.

Section 69A treatment of demonetisation-period cash deposits must consider whether the claimed source-realisation of business receivables and sales-was accepted on materially identical facts in an earlier assessment year. Although res judicata does not strictly govern income-tax assessments, the rule of consistency supports uniform treatment where the fundamental facts and source explanation remain unchanged. Without a material distinguishing change, the same business-receipt explanation should not be rejected; the addition requires fresh determination after considering the earlier assessment, supporting material, and providing a reasonable hearing opportunity.

Closing-stock valuation under the mercantile system must be assessed as part of an integrated going-concern exercise. A reduced closing-stock value that also lowers opening stock in the succeeding year increases that year's profit; where the Department does not establish distortion of profits for the relevant year, the adjustment is revenue-neutral. The resulting tax effect concerns only the timing of taxability, not the accrual of real income, so an addition based solely on that reduced valuation is unsustainable.

Unsigned electronic notices issued under Section 148 to initiate income-tax reassessment must comply with the CBDT requirement that notices issued through the e-proceedings facility bear the Assessing Officer's digital signature. Where a reassessment notice was neither digitally nor manually signed, it was invalid and could not confer jurisdiction to reassess income. The resulting reopening proceedings and consequential assessment were quashed.

Dividend income of a recognised staff provident fund is exempt under Section 10(25). Misreporting that income in the return under Section 10(35) does not change its exempt character or justify its disallowance under Section 115BBDA. Delayed employees' provident-fund and ESI contributions concern a separate issue and cannot support disallowance of the fund's dividend income. The dividend disallowance under Section 115BBDA was deleted.
