Inordinate delay in adjudication: unexplained delays undermine natural justice and invalidate further administrative steps.
The challenge contested whether inordinate and unexplained delay in adjudication violated the principles of natural justice, causing serious prejudice by impairing the petitioner's ability to defend. The court found the respondents' explanations-frequent changes in adjudicating officers and accommodation of co-noticees-insufficient, applied precedent that excessive unexplained delay vitiates proceedings, and emphasized the duty of authorities to conduct timely adjudication or supply adequate justification for delay.

Disallowance of expenditure related to exempt income: apportionment required and actual exempt income is a prerequisite.
Disallowance of expenditure relating to exempt income requires identification and apportionment of expenses attributable to non taxable receipts; only expenditure expended to earn taxable income may be claimed. Courts interpret "in relation to" expansively and reject reliance on the spender's dominant purpose. The existence of actual exempt income is necessary to invoke the disallowance rule, and post enactment explanatory amendments that alter prior law are not retrospective.

Proceeds of crime: pre-existing property cannot be provisionally attached absent equivalent-value connection under the Prevention of Money Laundering Act.
Provisional attachment under the Prevention of Money Laundering Act requires a reasonable nexus between the attached property and the alleged criminal activity; only property derived from criminal activity, the value of such property, or equivalent-value property held domestically qualifies. Pre-existing immovable assets purchased before the scheduled offence cannot be attached absent qualification as equivalent-value property, whereas challenges to movable asset attachments are to be pursued through available remedies.

Make available requirement for technical services prevents taxation where consultancy did not transfer technical knowledge, preserving source-based taxation.
The fees did not qualify as Fees for Technical Services because the make available condition-requiring transfer, transmission or enablement of technical knowledge-was not met; the domestic exception for services utilized to earn income from a source outside India applied since the services related to tournaments held abroad, and income attributable to any Service Permanent Establishment is taxable under the DTAA business profits regime.

Reasons to believe requirement in customs seizures: judicial review limits fact-finding and adjudication must address documentation and recordal of reasons.
Interpretation of the reasons to believe requirement under section 110 of the Customs Act centers on whether citation of statutory provisions in a seizure panchnama suffices versus the need for factual particulars. The court noted conflicting precedents, factual disputes about production of transport documents and e way bill timing, and emphasized that disputed factual issues fall to adjudicatory proceedings rather than writ review, urging expeditious adjudication and cooperation.

Deductibility under Section 80P(2)(d): interest from co operative bank deposits may qualify if linked to primary co operative activity.
Interest earned by credit co-operative societies from deposits with co-operative banks is examined for eligibility under Section 80P(2)(d), focusing on whether such receipts bear the requisite nexus to the societies' primary credit-providing activities and on the statutory meaning of co-operative bank as interpreted in judicial precedents that have largely favoured allowance of the deduction.

Arbitral autonomy: referral courts must limit Section 11 scrutiny to prima facie existence of arbitration agreements.
The referral court's inquiry under Section 11 is limited to the prima facie existence of an arbitration agreement; issues such as alleged accord and satisfaction and mixed questions of law and fact do not negate the arbitration clause and are within the arbitral tribunal's exclusive competence. Legislative intent behind the 2015 amendments supports minimal judicial interference at the appointment stage, and limitation under Section 11(6) should be confined to timeliness, leaving substantive limitation defenses to the tribunal.

Mandatory Draft Assessment Order under Section 144C preserves DRP review and invalidates final assessments issued without it.
Section 144C establishes a self-contained, multi-tiered assessment regime for international-transaction assessees in which the Dispute Resolution Panel exercises independent, enhanced review distinct from Section 144B. Framing the draft assessment order is an integral statutory step that preserves the assessee's right to challenge proposed findings; omission of that draft-stage procedure is therefore a substantive breach of the Section 144C code rather than a mere procedural irregularity. Remand under Section 153(6) does not revive assessments once the limitation periods in sub-sections (3) and (4) of Section 153 have expired.

Prospective application of tax amendment preserves taxpayer expectations and limits disallowance of expenses to stated effective years.
The issue is whether the Explanation to Section 14A introduced by the Finance Act, 2022 applies retrospectively or prospectively, particularly for assessment years where no exempt income arose. The Court analysed the Memorandum to the Finance Bill, relevant precedents, and the principle that tax laws altering existing legal positions are not to be given retrospective effect unless expressly or necessarily implied. It concluded the Explanation must operate prospectively from the effective date stated in the Memorandum, maintaining taxpayer expectations and legal certainty.

Taxation of Royalties: domestic law amendments cannot override DTAA interpretation; telecommunication payments not royalties.
The court held that unilateral domestic amendments to the statutory definition of royalty cannot alter the meaning of that term in a DTAA; treaty terms are to be interpreted by their plain meaning, guided by international law principles, OECD commentary, and precedents, and payments for telecommunication services or satellite transponder capacity do not qualify as royalties under the relevant DTAA.

Fe content on WMT basis determines export duty, lowering the applicable rate and enabling recovery of excess duty paid.
Assessment of iron ore export duty requires computation of Fe on a Wet Metric Ton basis by deducting moisture using the formula Iron content (as received) = Fe x (100 - M) / 100. Applying this WMT calculation against the customs notification framework that prescribes duty rates tied to measured Fe percentage results in a lower duty classification and a corresponding right to recover any excess duty paid when the measured Fe falls below the specified threshold.

Service of show cause notice: ensure proper notice and opportunity before tax orders; fresh notice and reasoned hearing required.
Proper service and transparent consideration of assessee replies are procedural prerequisites before passing tax assessment orders. Where portal non-reflection of notices and uncertainty about consideration of replies arises, the assessee is entitled to benefit of doubt. The court required that the impugned order be treated as a notice for filing a written reply within a short period, directed issuance of a fresh notice in the prescribed manner with a clear minimum notice period, mandated the assessee's appearance, and obliged the assessing officer to pass a reasoned and speaking order within a defined timeframe after valid service.

Customs duty liability on redemption: assessment under Section 28 triggers interest under Section 28AB for delayed payment.
The court concluded that duty liability arises when an owner redeems confiscated goods under Section 125(2), while the procedural assessment and determination of that duty can be carried out under Section 28, and that the interest provision of Section 28AB applies where Section 28 is invoked for such duties; the Jagdish Cancer ratio does not preclude applying Section 28 in confiscation-redemption assessments.

Limitation under Section 153C: six-year period runs from receipt of seized documents, requiring assessment under Section 153C.
Where seized assets, documents and digital data recovered from a third party are found to relate to another person, the date on which the Assessing Officer having jurisdiction receives those seized materials is the deemed date of search for reckoning the six-year limitation period; that deemed date determines the relevant assessment year and which prior six assessment years fall under the special procedure for initiating assessments under Section 153C.

Initiation of penalty proceedings: limitation runs from the Assessing Officer's reference, barring belated penalty orders.
Initiation of penalty proceedings occurs when the Assessing Officer makes a reference to the competent authority; the subsequent show cause notice is a procedural opportunity and does not restart the limitation period, so the statutory limitation for completing penalty proceedings runs from the date of the Assessing Officer's reference and a penalty order passed after that period is time barred.

Faceless assessment procedure must govern issuance of Section 148 notices in international tax matters, irrespective of residency.
The court held that the plain language of the faceless scheme, Section 144B(2) and the CBDT order requires that issuance of Section 148 notices in matters involving international tax charges comply with the mandatory faceless assessment procedure, irrespective of the taxpayer's residency status, and that notices issued without adherence to that procedure are inconsistent with the statutory scheme.

ITC blocking under Rule 86A: restricts orders to credit presently available in the electronic credit ledger, limiting retrospective blockage.
Rule 86A(1) functions as a temporary protective mechanism that may be invoked only where input tax credit is currently available in the taxpayer's electronic credit ledger and the officer has reasons to believe that such present credit has been fraudulently availed or is ineligible; the expression "amount equivalent to such credit" must be read together with the condition of availability in the ECL and does not authorise retrospective blocking of ITC already utilised or refunded.

Exhaustion of statutory remedies prevents direct writ challenges to tax demands absent exceptional circumstances or factual disputes.
The court held that exhaustion of statutory remedies bars writ relief where efficacious alternate remedies exist and where resolution requires factual or classification inquiries; finding no exceptional circumstances to bypass the statutory process, the court dismissed the writ petitions but granted liberty to the petitioners to pursue statutory remedies, including filing responses to show cause notices or appeals against adjudication orders within the period allowed, subject to compliance with prescribed conditions such as pre-deposit obligations.

Reassessment limitation: commencement depends on AO's recorded satisfaction, not the search date, for non-searched entities.
Reassessment of a non-searched entity under Section 153C must be measured from the date the Assessing Officer records satisfaction about the seized material's relevance to that entity, not from the date of the search when the same AO is involved; the proviso to Section 153A(1) prevents the extended limitation period introduced by the 2017 amendment from applying to searches before the statutory cutoff, and physical handover of materials is a machinery provision rather than the substantive commencement trigger.

Transaction value protection: declared import price accepted; principal-use classification of motor controllers affirmed after procedural defects in reassessment were found
The tribunal upheld the declared transaction value, finding that the authority enhanced assessable value without following statutory procedures and without proving non-comparability; NIDB assessed-value data alone was insufficient. On classification, the motor controllers were held to be parts principally used with electric motors and correctly classed under CTH 8503, with explanatory notes and the principal-use test displacing revenue's attempt to treat them as vehicle accessories.
