☐ For mode (b), has RPAD / SPAD / courier with acknowledgement been used?

☐ For mode (c), has the registered email been used?

☐ For mode (d), has portal publication been logged?

☐ For mode (e), does the newspaper circulate in the relevant locality?

☐ For mode (f), has non-practicability of other modes been documented?

☐ Has the deemed-service date been determined under sub-s. (2)?

☐ For postal service, has sub-s. (3) presumption been verified?

☐ Has the registered address / email / phone on registration been verified current?

☐ For taxpayer rebuttal, has documentary trail been built?

☐ Has the s. 160(2) belated-challenge bar been considered?

☐ For Department, has service evidence been preserved?

☐ Has the Maneka Gandhi procedural-fairness framework been observed?

☐ Has the Mafatlal procedural-fairness framework been applied?

☐ Has the Calcutta Discount Co. jurisdictional-foundation framework been considered?

☐ Has audit-trail of service event been preserved?

☐ Has the file been reviewed for audit-defensibility?

Example 1 — Portal-based service

Facts: Department issues SCN under s. 73 to taxpayer through portal (mode d). Portal publication logged on 15-Aug-2025. Taxpayer does not respond. Department proceeds with adjudication. Taxpayer subsequently challenges, alleging non-receipt.

Analysis: Sub-s. (2) — deemed-service date is portal publication date (15-Aug-2025). Taxpayer's obligation to monitor portal is foundational under modern compliance. Bharti Airtel framework reinforces portal-monitoring obligation. Non-receipt allegation requires rebuttal evidence — portal-monitoring lapse is generally not sustainable. Section 160(2) barring belated challenge applies if earlier proceedings ran without challenge.

Result: Service deemed effective. Taxpayer's challenge fails. Practitioner discipline — monitor portal systematically.

Example 2 — Postal service rebuttal

Facts: Department sends adjudication order by speed post on 10-Sep-2025 to taxpayer's registered address. Normal transit period — 7 days. Deemed receipt — 17-Sep-2025. Taxpayer alleges non-receipt; produces postal-certificate of non-delivery dated 20-Sep-2025 (cover returned undelivered).

Analysis: Sub-s. (3) presumption rebutted. Documentary evidence of non-delivery satisfies Banwari Lal positive-evidence standard. Department's response — verify registered address is current; if address changed without amendment, taxpayer's lapse contributes. If address is current, Department must use alternative mode.

Result: Postal presumption rebutted. Alternative service required.

Example 3 — Mode (f) affixing fallback

Facts: Department attempts service via modes (a) through (e) but each fails — taxpayer not traceable at registered address, email bounces, portal monitoring shows no engagement, newspaper publication completed. Department resorts to mode (f) affixing at last known business premises.

Analysis: Mode (f) is fallback — only when other modes are not practicable. Department's documentary trail of non-practicability is essential. Photographs of affixing, non-practicability documentation, and earlier-mode attempts must be preserved. Practitioner challenge — verify non-practicability standard is met.

Result: Mode (f) effective if non-practicability documented. Otherwise vulnerable to challenge.

Example 4 — Section 160(2) belated challenge bar

Facts: Taxpayer received SCN through portal but did not respond. Assessment order passed. Taxpayer filed appeal under s. 107 against the assessment order. After dismissal of appeal on merits, taxpayer files writ challenging original SCN service.

Analysis: Section 160(2)(b) — earlier proceedings (appeal) ran without challenge to service. Belated service-challenge barred. Writ for service-defect must fail on this ground. Substantive merits-defence is the only remaining route.

Result: Service-defect challenge barred. Practitioner lesson — raise service-defect at earliest opportunity to preserve.

Example 5 — Modern combined-mode service

Facts: Department issues DRC-01 under s. 73 — published on portal (mode d) on 1-Oct-2025; registered email sent to taxpayer's registered email (mode c) on same date; speed post sent (mode b) on same date. Taxpayer alleges non-receipt of all three.

Analysis: Triple-mode service — Departmental discipline. Each mode independently establishes service. Portal publication and email delivery logged; postal acknowledgement received. Taxpayer's non-receipt allegation requires rebuttal of all three modes. Documentary discipline of Department is comprehensive — service deemed effective.

Result: Service effective. Combined-mode discipline forestalls service-defect challenge.
