Marginal note — Officers to assist proper officers
72. (1) All officers of Police, Railways, Customs, and those officers engaged in the collection of land revenue, including village officers, officers of State tax and officers of Union territory tax shall assist the proper officers in the implementation of this Act.
(2) The Government may, by notification, empower and require any other class of officers to assist the proper officers in the implementation of this Act when called upon to do so by the Commissioner.
[Section 72 enforced w.e.f. 01.07.2017 by Notification 9/2017-CT dated 28.06.2017. Operational integration with Customs Act, 1962 for joint investigations involving imports / exports; with Cr.P.C. for police assistance during search-and-seizure operations under s. 67 and arrest under s. 69; with Railway Act, 1989 and the parallel Customs / Railway Property (Unlawful Possession) Act for railway-property cases; with state tax officers under the SGST Acts for cross-empowerment under s. 6 read with s. 5; with land revenue officers under the State Land Revenue Codes for property attachment / recovery proceedings under s. 79. Cross-empowerment notifications under s. 6 of the CGST Act, the SGST Acts, and the UTGST Act, 2017 operationalise the inter-officer assistance framework.]
BLOCK 2 — STATUTORY MAP
ELEMENT OF THE PROVISION
OPERATIVE READING
Sub-s. (1) — Enumerated assisting officers
Statutory obligation on six categories of officers — (i) Police; (ii) Railways; (iii) Customs; (iv) officers engaged in collection of land revenue (including village officers); (v) officers of State tax (SGST); (vi) officers of Union territory tax (UTGST). All these officers ‘shall assist’ — mandatory language. The provision is a statutory mandate for inter-Departmental cooperation.
Sub-s. (2) — Government notification power
Government may, by notification, empower and require any other class of officers to assist when called upon by Commissioner. This is a residual enabling provision — covers any future inter-Departmental cooperation need not anticipated in sub-s. (1). Examples — IT Department officers, Customs intelligence units, financial intelligence units, banking regulators, etc.
Police assistance — operational integration
Police assistance covers — (i) physical presence during search-and-seizure under s. 67 in sensitive premises; (ii) law-and-order support during enforcement operations; (iii) assistance in arrest execution under s. 69; (iv) registration of FIR for offences also constituting IPC / state law offences (e.g., obstruction, false statements); (v) custody arrangements for arrested persons under Cr.P.C. ss. 41, 50, 57, 167.
Customs assistance — joint investigations
Customs assistance covers — (i) joint operations on imports / exports involving GST issues (IGST under-payment, false rebate claims, etc.); (ii) sharing of import / export data — Bills of Entry, Shipping Bills, EXIM data through ICEGATE / SVB; (iii) coordination on SEZ-related enquiries; (iv) joint enforcement in customs-bonded areas. Operational interface through ICEGATE data exchange and DGGI / Directorate of Revenue Intelligence (DRI) coordination.
Railway assistance — physical and intelligence
Railway assistance covers — (i) physical assistance for inspection of goods in railway transit at goods sheds / parcel offices; (ii) information on railway receipts (RRs) — consignor / consignee, goods description, weight, freight; (iii) detention of goods in railway premises pending GST verification under s. 129; (iv) coordination with Railway Protection Force (RPF) for sensitive operations.
Land revenue officer assistance — recovery integration
Land revenue officer assistance covers — (i) property attachment under s. 79(1)(f) for recovery of GST dues as arrears of land revenue; (ii) sale of attached property through revenue authorities; (iii) survey and identification of properties; (iv) coordination with district administration for recovery proceedings. The link to land revenue recovery is operationally crucial — many GST recoveries finally proceed as land revenue recovery under the State Codes.
State / UT tax officer assistance — cross-empowerment
Cross-empowerment under s. 6 of CGST Act / s. 6 of SGST Acts / s. 6 of UTGST Act enables State / UT officers to act as proper officers under CGST and vice versa. This is the most operationally significant inter-officer assistance — taxpayers under CGST jurisdiction may receive notices from State tax officers and vice versa. Notification 39/2018-CT and subsequent notifications operationalise the cross-empowerment.
Sub-s. (2) — Empowerment of other class of officers
Empowerment is by Government notification — Central Government for CGST Act. Empowered officers ‘shall assist when called upon to do so by the Commissioner’. Two conditions — (i) Government notification empowering the class; (ii) Commissioner's specific call for assistance in particular case. Both are required.
‘Implementation of this Act’ — scope of assistance
Assistance is in ‘implementation of this Act’ — broad reach. Covers (i) investigation under ss. 67, 70; (ii) arrest under s. 69; (iii) audit / scrutiny under ss. 65, 66, 71; (iv) recovery under ss. 78, 79; (v) detention / confiscation under ss. 129, 130; (vi) any other proceeding under the Act. The scope is co-extensive with the Act's enforcement requirements.
Operational interface — joint operations protocol
Joint operations typically require advance coordination — call from CGST proper officer to assisting officer's superior, formal communication, briefing on case background, agreement on roles. For high-profile operations involving police / customs / multi-agency, written joint-operations memorandum is the norm. Documentation of assistance is required for any later defence of the operation.
Cross-empowerment under s. 6 read with s. 72
Section 6 cross-empowers State / UT officers to act as ‘proper officer’ under CGST Act and Central officers to act under SGST Act, subject to conditions. Section 72 imposes assistance obligation. The two together create a fully integrated enforcement framework — a notice or order by any of the cross-empowered officers is treated as a notice / order under the respective Act.
Constitutional foundation — Article 246A and Article 269A
The inter-Department cooperation in s. 72 has constitutional foundation in Article 246A (concurrent levy of GST by Centre and States) and Article 269A (assignment of GST on inter-State trade and IGST). Cooperation between Centre and State tax authorities is a constitutional necessity for the dual GST model to function effectively.
BLOCK 3 — COMMENTARY
1. Statutory architecture — the inter-Departmental cooperation mandate
Section 72 is the statutory mandate for inter-Departmental cooperation in the implementation of the CGST Act. It addresses a fundamental operational reality of tax enforcement: a Central tax officer, however empowered, cannot effectively investigate, audit, search, arrest, or recover taxes without the active assistance of other government officers whose primary functions lie elsewhere. The provision lists six categories of officers — Police, Railways, Customs, land revenue, State tax, UT tax — who shall assist the proper officers in the implementation of the Act. The mandatory language is significant: the assistance is not optional or discretionary; it is a statutory obligation.
The provision operates alongside Section 6 of the CGST Act (cross-empowerment of officers under SGST / UTGST Acts to act as proper officers under CGST and vice versa) and parallel provisions in the SGST and UTGST Acts. Together, these provisions create a fully integrated enforcement framework in which Central, State, and Union territory tax officers act as a unified enforcement machinery, supported by the broader law-enforcement and revenue-administration apparatus of the Indian Union.
2. Constitutional foundation — Article 246A and the dual GST model
The cooperation mandate in s. 72 rests on the constitutional architecture of the dual GST model under Article 246A and Article 269A. Article 246A confers concurrent power on Parliament and State Legislatures to make laws with respect to GST (subject to Parliament's exclusive power over inter-State supply). Article 269A provides that GST on inter-State trade or commerce shall be levied and collected by the Government of India and apportioned between Union and States. The dual model thus requires constant cooperation between Central and State tax authorities to administer effectively — and s. 72 (together with s. 6) is the legislative expression of this constitutional design.
Within the dual model, a single taxpayer may be subject to concurrent jurisdiction of both Central and State tax authorities. The cross-empowerment under s. 6 read with the s. 72 assistance mandate ensures that taxpayers are not subject to duplicative or conflicting enforcement — a single notice or order from a cross-empowered officer covers the taxpayer's CGST and SGST obligations. This rationalisation is critical to the dual GST model's operational coherence.
3. Police assistance — the operational backbone of enforcement
Among the six enumerated assisting authorities, police assistance is the operational backbone of GST enforcement. The Central tax officer is not himself a police officer; he does not carry weapons, does not have lawful authority for crowd control, and does not have the local intelligence and territorial reach of the State Police. For any enforcement operation involving (i) search-and-seizure under s. 67 in sensitive premises — large factories, populated commercial areas, premises where resistance is anticipated; (ii) law-and-order support during enforcement actions — protection of officers and evidence; (iii) arrest execution under s. 69 — physical apprehension and transit; (iv) custody arrangements under Cr.P.C., police assistance is operationally indispensable.
Police assistance is also legally essential for registration of FIR where conduct also constitutes an IPC / state-law offence — for example, obstruction of a public servant (IPC s. 186, BNS s. 221), criminal force to deter a public servant (IPC s. 353, BNS s. 132), false statements made to public servant (IPC ss. 191-200, BNS ss. 232-241). The State Police register the FIR; the CGST officer files the GST-specific complaint under s. 132 in parallel. Coordination between the two tracks requires inter-Departmental cooperation at the field level.
4. Customs assistance — joint operations on cross-border and SEZ matters
Customs assistance under s. 72 operates at the interface of GST and Customs regimes. The CGST Act and the Customs Act, 1962, work together for goods crossing international borders — IGST is levied on imports under the Customs Tariff Act, 1975, alongside Basic Customs Duty and other duties; exports are zero-rated under s. 16 of the IGST Act with provision for either refund of unutilised ITC or refund of IGST paid. The interface creates several scenarios in which Customs assistance is critical to GST enforcement.
• False export-rebate claims — Exporters may claim refund of IGST paid on exports under s. 16 IGST Act read with Rule 96 CGST Rules, but the underlying export may be partly or wholly fictitious. Customs data on actual export quantities, FOB values, and ports of departure are critical to verify such claims. The Customs assistance enables CGST officers to obtain and verify Shipping Bill data, container records, and customs-broker confirmations.
• IGST under-payment on imports — Importers may under-pay IGST on imports through under-valuation or misclassification. Customs data on assessable value, classification, and IGST paid is essential. Joint investigations between CGST and Customs are common in such cases.
• SEZ supplies — Supplies to SEZ are zero-rated under IGST law but with significant documentation requirements. Customs Authorities at SEZ administer the SEZ Customs framework; coordination with CGST is required to verify entry / removal of goods and applicability of zero-rating.
• EXIM data exchange through ICEGATE — The Indian Customs EDI Gateway (ICEGATE) is the data backbone for Customs operations. CGST officers can obtain import / export data through ICEGATE for verification of corresponding entries in GSTR-1 / 3B / 9. This data exchange is one of the most-used forms of Customs assistance.
• DRI / DGGI coordination — The Directorate of Revenue Intelligence (DRI) under Customs and the Directorate General of GST Intelligence (DGGI) under CGST often run parallel investigations on the same suspected entities. Inter-agency coordination, often facilitated through the CBIC at apex level, enables joint operations and consolidated cases.
5. Railway assistance — physical and intelligence support
Railway assistance covers both physical operations and intelligence-sharing. Physically, railway officials assist in (a) inspection of goods in railway transit at goods sheds and parcel offices; (b) detention of goods in railway premises pending GST verification under s. 129; (c) coordination with Railway Protection Force (RPF) for sensitive operations involving railway-property dimensions. On intelligence, Railways provides information on railway receipts (RRs) — consignor / consignee, goods description, weight, freight — which is critical evidence in many transit-based GST investigations.
The interface with s. 68 (inspection of goods in movement) is particularly important. Where goods are moved by railway, the documents to be carried under s. 68 read with Rule 138 include the railway receipt (RR) in addition to invoice and e-way bill. Verification of railway transit therefore requires Railway cooperation — RR confirmation, consignor identification, actual delivery confirmation. Joint inspections at major railway goods sheds (Howrah, Mumbai CST, Delhi DSJ, Chennai Egmore) are routine.
6. Land revenue officer assistance — recovery integration
Land revenue officer assistance integrates GST recovery with the State Land Revenue Codes. Under Section 79(1)(f) CGST Act, the proper officer may, ‘upon a certificate prepared by the proper officer and signed by him specifying the amount due’, send it to the Collector of the district in which the defaulter has property — and the Collector shall proceed to recover the amount as if it were an arrear of land revenue. This recovery route is operationally critical for substantial defaults — particularly where the taxpayer's bank accounts are exhausted under s. 79(1)(c) or the taxpayer has been deregistered.
Land revenue recovery proceeds under the State Land Revenue Codes — Punjab Land Revenue Act 1887, Bombay Land Revenue Code 1879, Madhya Pradesh Land Revenue Code 1959, etc. These Codes provide comprehensive frameworks for attachment, sale, and recovery of properties — both moveable and immoveable. The land revenue officers — Collector, Tehsildar, village officers (Patwari, Talati) — execute the recovery. The cooperation mandate in s. 72(1) covers the entire recovery chain.
The village officer category in s. 72(1) — Patwari / Talati / Lekhpal — is particularly important for property identification and rural recoveries. Village land records (revenue records, mutation entries, land-holding details) are maintained at the village level by these officers, and their cooperation is essential for identifying properties of GST defaulters in rural areas.
7. State / UT tax officer assistance — cross-empowerment under s. 6
The most operationally significant inter-officer assistance is between Central and State (or UT) tax officers under Section 6 cross-empowerment. Section 6(1) provides that officers appointed under the SGST Act / UTGST Act are authorised to be proper officers for the purposes of the CGST Act, subject to such conditions as the Government shall, on the recommendation of the Council, by notification, specify. Parallel provisions in the SGST Acts and UTGST Act provide the reverse cross-empowerment.
Operationally, Notification 39/2018-CT and subsequent notifications operationalise the cross-empowerment, typically dividing taxpayers between Central and State jurisdiction by turnover (large taxpayers — Central; small taxpayers — State) and by specific case-allocation. Where a taxpayer is allocated to Central jurisdiction, only Central officers act as proper officers for that taxpayer's CGST + SGST + IGST liabilities. Where the taxpayer is allocated to State jurisdiction, only State officers act for all GST components. This avoids duplicative or conflicting enforcement.
Cross-empowerment is not unconditional. The conditions in the notifications govern (i) what proceedings the cross-empowered officer can initiate; (ii) what officers are excluded (e.g., very senior officers may not exercise cross-empowered jurisdiction); (iii) the period of cross-empowerment; (iv) cooperation protocols between Central and State officers. The cross-empowerment framework has been the subject of significant litigation, particularly in the early years of GST, on the question of jurisdictional overlap.
8. Sub-section (2) — the residual enabling power
Sub-section (2) is a residual enabling power. It permits the Government to empower and require any other class of officers — not enumerated in sub-s. (1) — to assist the proper officers when called upon by the Commissioner. The provision contemplates two conditions: (a) Government notification empowering the class of officers; (b) Commissioner's specific call for assistance in a particular case. The residual nature ensures that any future inter-Departmental cooperation need can be addressed through notification, without legislative amendment.
Operational examples of sub-s. (2) empowerment could include — IT Department officers for coordinated tax-evasion investigations (where the same conduct constitutes both Income Tax and GST evasion); Customs intelligence units beyond ordinary Customs assistance; financial intelligence agencies for cases involving suspected money laundering; banking regulators for cases involving banking-channel evasion. As GST enforcement matures, additional categories may be notified.
9. Departmental View from CBIC Handbook of GST Law and Procedures (DGGST, 2024)
The CBIC Handbook (Chapter VIII on Enforcement) treats inter-Departmental cooperation under s. 72 as foundational to effective enforcement. The Handbook directs field officers to plan major enforcement operations in advance through formal communication with the relevant assisting authorities — police superintendents, customs commissioners, railway divisional managers, district collectors, state tax commissioners. Last-minute requests for assistance are discouraged; advance planning is the norm.
On joint operations with State tax authorities under cross-empowerment, the Handbook emphasises (i) clear identification of lead authority and supporting authority; (ii) single point-of-contact for the taxpayer; (iii) consolidated documentation — single SCN, single adjudication order, single appellate proceeding; (iv) sharing of evidence and findings across jurisdictions; (v) coordinated response to writ challenges. The Handbook expressly notes that uncoordinated parallel proceedings by Central and State authorities expose the action to writ challenge on grounds of duplication and double jeopardy.
On Customs / DGGI coordination, the Handbook directs that for any case involving import / export dimensions, the DGGI / DRI / Customs Commissionerate should be informed at the outset, and joint investigation framework should be considered. The same applies for cases involving suspected money laundering — Enforcement Directorate may need to be informed, with formal Predicate Offence notification under PMLA.
The Handbook also addresses operational protocols for police assistance during search-and-seizure under s. 67 and arrest under s. 69 — formal written request to the District Superintendent of Police giving 48-72 hours' advance notice, briefing on case background, agreement on roles (police for law-and-order; CGST for technical evidence collection), and post-operation joint debrief. Documentation of police assistance is required for defending the operation in subsequent writ / criminal proceedings.
CIRCULARS, INSTRUCTIONS & NOTIFICATIONS
• Section 6 of the CGST Act, 2017 dated Statutory — Authorisation of officers of State tax or Union territory tax as proper officer in certain circumstances. Section 6 cross-empowers officers of State tax / UT tax to act as proper officers under CGST Act, subject to conditions notified. Parallel provisions in SGST Acts and UTGST Act provide reverse cross-empowerment. Operative content: (i) Section 6(1) — central authorisation of State / UT officers; (ii) Section 6(2)(a) — proper officer issuing order to forward copy to jurisdictional officer of the other tax; (iii) Section 6(2)(b) — bar on initiation of proceedings on same subject-matter by both Central and State / UT officers — avoids duplicative action. Together with s. 72, this creates the integrated enforcement framework.
• Notification 39/2018-CT dated 04.09.2018 — Allocation of taxpayers between Central and State tax administration. Operationalises the cross-empowerment under s. 6 by allocating taxpayers between Central and State jurisdiction. Broad framework: (i) 90% of taxpayers below Rs. 1.5 crore turnover allocated to State; 10% to Central; (ii) 50% of taxpayers above Rs. 1.5 crore turnover allocated to State; 50% to Central; (iii) computer-randomised allocation within the percentages; (iv) allocation is for both CGST and SGST proceedings — the allocated authority handles all GST components for that taxpayer. The allocation framework has been refined through subsequent notifications and Circular instructions.
• Circular 1/1/2017-IGST dated 07.07.2017 — Clarifications on cross-empowerment and inter-jurisdictional issues. Issued by CBIC early in the GST regime to address operational issues on cross-empowerment. Operative directions: (i) The allocated authority is the lead authority for proceedings; (ii) cross-empowered officers should not initiate parallel proceedings on the same subject-matter; (iii) where a cross-empowered authority needs to take action in another authority's jurisdiction, formal communication and consent of the lead authority should be obtained; (iv) information sharing through the GST Network for ITC verification, GSTR matching, etc. Circular has been supplemented by subsequent instructions on operational coordination.
• Section 79(1)(f) of the CGST Act, 2017 dated Statutory — Recovery as arrears of land revenue. Section 79(1)(f) is the operational link between GST recovery and land revenue recovery under State Codes. Operative content: (i) Where amount is due from a defaulter, the proper officer may prepare a certificate specifying the amount and send it to the Collector of the district in which the defaulter has property or resides or carries on business; (ii) the Collector shall proceed to recover the amount as if it were an arrear of land revenue; (iii) the Collector's powers under the State Land Revenue Code are fully available — attachment, sale, attachment of bank accounts, etc. Section 72(1) covers the entire chain of officers involved — Collector, Tehsildar, village officers.
PROCEDURE — STEP-BY-STEP
Step 1: Identification of need for assistance
The CGST proper officer assesses, at the planning stage of any enforcement action, the categories of inter-Departmental assistance required. For search under s. 67 — police, possibly customs (if cross-border dimension), possibly railway (if transit involved). For arrest under s. 69 — police mandatory, possibly customs / state tax for joint operation. For recovery under s. 79 — land revenue officers, banking authorities under s. 79(1)(c). For audit / scrutiny — typically minimal external assistance.
Step 2: Internal authorisation and case file
The proper officer obtains internal authorisation from the appropriate level (Joint Commissioner / Commissioner) for the operation, including for inter-Departmental cooperation. Case file documents (a) factual background; (b) statutory authorisation under s. 67 / 69 / 71 / 72 etc.; (c) assistance required and from which authorities; (d) operational plan including roles of assisting officers; (e) timing.
Step 3: Formal communication to assisting authorities
Formal written communication to the head of each assisting authority — Superintendent of Police, Customs Commissioner, Railway Divisional Manager, District Collector, State Tax Commissioner, etc. The communication includes (a) statutory authority (s. 72 read with the relevant operative section); (b) summary of the case; (c) specific assistance required; (d) timing; (e) point-of-contact details. Advance notice — typically 48-72 hours for non-urgent operations, with same-day capability for urgent operations.
Step 4: Coordination meeting / briefing
Coordination meeting between CGST team and the assisting authority's representative — typically held at a senior level (Joint Commissioner CGST and Superintendent of Police, for example). Briefing covers (a) case background; (b) operational plan; (c) roles of each authority; (d) protocols for handling on-site situations — resistance, persons present, evidence handling; (e) communication channels; (f) post-operation responsibilities.
Step 5: Pre-operation logistics
Logistics — assembly point, transport, identification documents for each officer, equipment (notebooks, video / camera, evidence-bags), forms (panchnamas, statement-recording, seizure memos), legal authorisations (search authorisations, arrest authorisations, summons), counsel availability for after-the-fact validation if needed. All officers — CGST and assisting — should have ID cards visible during operation.
Step 6: Execution of operation — lead authority and supporting authority
The CGST officer is the lead authority for the substantive operation — search, seizure, statement-recording, arrest execution. The assisting authorities provide their specific support — police for law-and-order and physical apprehension; customs for cross-border data / evidence; railway for transit access; land revenue for property identification / attachment. Lead-supporting protocol clearly maintained throughout. CGST officer signs the operational documents; assisting authority officers may be witnesses.
Step 7: Documentation of assistance
All assistance rendered is documented — (a) officers present from each authority by name and rank; (b) specific assistance rendered — entry into premises, witness to seizure, escort during arrest, attachment of property, etc.; (c) timing; (d) any incidents during operation. This documentation is critical for defending the operation against writ / criminal challenges based on procedural irregularity.
Step 8: Joint debrief and case progression
Post-operation joint debrief between CGST team and assisting authority. Issues identified — operational gaps, evidence priorities, follow-on actions, parallel proceedings (e.g., FIR by police for IPC offence). Case progresses through the CGST track (SCN, adjudication, prosecution under s. 132) and any parallel tracks (IPC / state law FIR by police, Customs proceedings for import / export dimensions).
Step 9: Information-sharing and joint case management
Ongoing information sharing between CGST and the assisting authorities throughout the case lifecycle. Evidence collected by one authority is shared with the other; statements taken under different statutes are coordinated; parallel proceedings are progressed consistently. Risk of duplication or inconsistency is managed through joint case management protocols.
Step 10: Cross-empowerment proceedings — coordination with State / UT
Where cross-empowerment is involved — Central officer handling case allocated to State, or vice versa — coordination protocols apply. The allocated authority is the lead; the other authority is informed of all major actions (SCN issue, adjudication order, prosecution); information from the cross-empowered side is shared. Bar on parallel proceedings under s. 6(2)(b) is strictly observed.
Step 11: Recovery operations — Collector / Tehsildar assistance
For recovery under s. 79(1)(f) as arrears of land revenue, the proper officer prepares the certificate, forwards to Collector with supporting documents. The Collector proceeds under State Land Revenue Code — issues notices, attaches property, conducts sale. CGST proper officer maintains liaison with Collector's office throughout the recovery proceedings, provides additional information / documentation as needed.
Step 12: Banking sector assistance — s. 79(1)(c) attachment
For attachment of bank accounts under s. 79(1)(c), formal notice issued to the bank; bank's cooperation in freezing / debiting the account is the operational assistance. Banks are not explicitly enumerated in s. 72(1) but their cooperation has been established practice; formal notification under s. 72(2) may be considered as the framework matures.
Step 13: Writ defence — documentation of cooperation framework
Writ challenges to enforcement operations often allege procedural irregularities — improper authorisation, lack of safeguards, improper coordination. The CGST officer must be able to defend the operation by reference to (a) statutory authorisation under s. 67 / 69 / 71 / 72; (b) inter-Departmental coordination documentation; (c) compliance with DK Basu / Arnesh Kumar / Make My Trip standards; (d) cross-empowerment compliance.
Step 14: Closure and learnings
On closure of the operation / case — whether through SCN-adjudication, prosecution, compounding under s. 138, or quashing — joint debrief and lessons-learned review. Inter-Departmental cooperation is an evolving capability; each major operation refines protocols. Best-practices feed into Departmental SOPs.
Step 15: Reporting and information consolidation
Periodic reporting through DGGI / CBIC channels on the inter-Departmental cooperation framework — operations conducted, results achieved, gaps identified, refinements recommended. The cooperation framework is evolutionary and adjusts to operational needs and judicial guidance.
PRACTITIONER CHECKLIST
Section 72 inter — Departmental cooperation checklist (practitioner / taxpayer-side perspective)
□ Identify the assisting authority — police, customs, railway, land revenue, state / UT tax — for any major enforcement event affecting the client.
□ Verify the statutory authority for the assistance — s. 72(1) for enumerated categories; s. 72(2) for notified other categories.
□ Verify cross-empowerment if State tax officer is the lead authority for a CGST-related action — Notification 39/2018-CT and subsequent.
□ Examine the authorisation documents — joint operation memo, written request for assistance, advance notice to assisting authority.
□ Document the officers present from each authority by name and rank — names should appear in panchnamas / production memos.
□ On lead authority — for CGST substantive action, the CGST officer is the lead; for parallel IPC offences, police is lead.
□ Bar on parallel proceedings under s. 6(2)(b) — verify no duplication between Central and State authorities; raise as defence if duplicated.
□ For police assistance during search / arrest — DK Basu and Arnesh Kumar protocols apply to the police role as much as to CGST role.
□ For customs assistance — verify if ICEGATE data is being used; demand transparency on what Customs data forms the basis of CGST allegations.
□ For railway assistance — verify the railway officer's identification; railway receipts (RR) production should follow s. 70 framework.
□ For land revenue recovery under s. 79(1)(f) — verify the proper-officer certificate; raise procedural irregularities if Collector exceeds CGST scope.
□ For banking-channel attachment under s. 79(1)(c) — verify due process before bank account attachment; challenge if pre-determination attachment.
□ Documentation of the entire cooperation chain — critical for writ defence and substantive challenge.
□ Track parallel proceedings — CGST adjudication, IPC FIR by police, Customs proceedings — for consistency of factual narrative.
□ Coordinate counsel across tracks — GST counsel for CGST proceedings; criminal counsel for police-track; Customs counsel for customs-track.
□ Information requested under RTI from each assisting authority — documents, internal notings, communications.
□ Consistency check — statements made before different authorities should be factually consistent; inconsistencies become attack points.
□ Compounding evaluation under s. 138 — strategic exit available for CGST track even if parallel police track continues separately.
□ Closure documentation in client compliance docket — covers all tracks for institutional memory.
WORKED EXAMPLES
Example 1 — Joint CGST-Police operation for search under s. 67
Facts: DGGI Mumbai has actionable intelligence on a network of fake invoicing entities operating from a commercial premises in Vile Parle. Search authorisation under s. 67(2) is issued by the Joint Commissioner DGGI for raid on three premises. The premises are in a populated commercial area; resistance and crowd-gathering anticipated. CGST team plans the operation with assistance from local police under s. 72(1).
Step 1: Pre-operation — Joint Commissioner DGGI sends formal letter to Senior Inspector of Police, Vile Parle Police Station, 72 hours in advance, requesting police assistance for search operation on specified date. Letter references s. 72(1) and provides case summary, premises addresses, anticipated personnel requirement (10 police personnel including 2 women officers if women may be present at premises).
Step 2: Coordination meeting — One day before operation, Joint Commissioner DGGI meets Sr. Inspector of Police, briefs on case background, agrees protocols — police for law-and-order, premises entry, witness during search; CGST for substantive search, evidence collection, statement-recording, seizure.
Step 3: Execution on D-day — At 6 AM, three teams assemble — each team consists of 4 CGST officers (search team), 2 police personnel (uniform, armed), 2 panchas (independent witnesses). Teams reach the three premises simultaneously.
Step 4: On-premises action — Police secures premises entry, identifies persons present, maintains crowd-control. CGST officers serve search authorisation, conduct search, seize records / computers / mobile phones, record statements under s. 70, prepare panchnama. Police personnel sign panchnama as official witnesses (in addition to panchas).
Step 5: Resistance scenarios handled — At one premises, an employee attempts to delete data from a computer — police restrains; CGST seizes the computer and external drive immediately. At another, a person threatens an officer — police records the threat; an FIR is registered separately under IPC s. 353 / BNS s. 132 (criminal force to deter public servant).
Step 6: Post-operation — All three operations completed by 6 PM. Premises sealed where necessary; arrested persons (one at the main premises) escorted under police custody to nearest Magistrate. Joint debrief same evening; documentation finalised.
Result: Practitioner alignment — Joint CGST-Police operations are typical for sensitive search-and-seizure events. From the taxpayer-side perspective, the police presence does not change the legal status of the operation — it remains a s. 67 search under CGST authorisation, with police providing law-and-order support under s. 72. Procedural challenges to the operation (e.g., on DK Basu compliance for any arrest, on s. 67 panchnama protocol for the search) apply equally; police presence does not enhance the operation's legal validity.
Example 2 — Cross-empowerment dispute — Central and State proceedings on same subject
Facts: A manufacturer in Indore is allocated to Central tax jurisdiction per Notification 39/2018-CT. The Central CGST officer issues SCN under s. 73 for FY 2021-22 on alleged short-payment of Rs. 50 lakh tax. Subsequently, the State tax officer of Madhya Pradesh independently issues SCN under SGST Act s. 73 for the same period and same subject-matter, alleging short-payment of SGST component. Two parallel proceedings on the same subject-matter.
Step 1: Initial assessment — The parallel SCNs violate s. 6(2)(b) bar on initiation of proceedings on same subject-matter by both Central and State / UT officers. Per Notification 39/2018-CT, the manufacturer is allocated to Central — therefore Central is the lead authority, and State should not initiate parallel proceedings.
Step 2: Defence response — File reply to both SCNs preserving all rights. To Central SCN, file substantive reply addressing the allegations. To State SCN, file reply asserting (a) the manufacturer is allocated to Central; (b) State has no jurisdiction to initiate parallel proceeding under s. 6(2)(b); (c) the SCN is therefore without jurisdiction and should be dropped.
Step 3: Writ challenge to State SCN — File writ under Article 226 in Madhya Pradesh High Court for quashing of State SCN on jurisdictional grounds. Cite s. 6(2)(b), Notification 39/2018-CT, and CBIC Circular 1/1/2017-IGST.
Step 4: Likely outcome — High Court typically quashes the parallel SCN as without jurisdiction. The Central proceeding continues; State proceeding is closed.
Step 5: Practitioner takeaway — The s. 6(2)(b) bar is a strong defence against duplicate proceedings. Identify the allocation early; respond to any non-allocated authority's notice with explicit jurisdictional objection; preserve writ option.
Step 6: Counter-scenario — Where the manufacturer is allocated to State, the same logic operates in reverse — Central officer cannot initiate parallel proceeding. The bar protects taxpayers from being squeezed between Central and State for the same subject-matter.
Result: Practitioner alignment — Cross-empowerment under s. 6 read with s. 72 has been the subject of significant litigation. The bar on parallel proceedings under s. 6(2)(b) is robust and routinely enforced. Practitioners must verify allocation at the start of any case; identify the lead authority; defend against parallel proceedings by the non-allocated authority through explicit jurisdictional objection and, where needed, writ relief.
Example 3 — Customs-CGST joint operation on false export-rebate claim
Facts: An exporter in Bangalore claims refund of IGST paid on exports of textile goods under s. 16 IGST Act read with Rule 96 CGST Rules — Rs. 3 crore refund claim for Q3 FY 2023-24. CGST verification team notes that the export volumes appear high relative to declared turnover, and the corresponding GSTR-1 entries are concentrated in a few weeks. Suspecting circular trading and fake exports, the CGST officer seeks Customs assistance under s. 72(1).
Step 1: Pre-operation — CGST officer formally requests Customs Commissionerate, Bengaluru, for (a) Shipping Bill data for the exporter for the relevant period; (b) container records, customs-broker confirmations, port-of-shipment data; (c) FOB values and assessment records; (d) verification of actual export at the port. Customs provides data within 5 working days.
Step 2: Data analysis — Customs data shows (a) only 30% of declared exports are matched to actual Shipping Bills filed at Bengaluru Port; (b) remaining 70% appear to be exports through other ports — Mumbai, Chennai, Tuticorin; (c) further verification through ICEGATE shows that for 50% of the claimed exports, no Shipping Bill exists at any port — i.e., the exports are likely fake.
Step 3: Joint investigation — DGGI Bengaluru and Customs Bengaluru constitute a joint investigation team. Search authorisation under s. 67 issued for the exporter's premises and the customs-broker's office. Joint search operation conducted with police assistance under s. 72(1).
Step 4: Evidence collected — At exporter's premises — books showing fictitious export entries, dummy invoices, bank records showing circular fund flows. At customs-broker's office — communications confirming fictitious documentation, false declarations. Statements recorded under s. 70 from exporter's directors and customs-broker.
Step 5: Parallel proceedings — DGGI / CGST track: SCN under s. 74 for fraud / suppression for the refund claim; reversal of refund granted; demand of Rs. 3 crore tax with interest and 100% penalty under s. 74. Customs track: proceedings under Customs Act for false declarations; potential prosecution under Customs Act s. 132 (analogous to GST s. 132).
Step 6: Coordinated narrative — Both tracks proceed on the same factual narrative — fictitious exports for false refund claim. Coordinated information sharing; consistent factual position; coordinated counsel response on the taxpayer side.
Result: Practitioner alignment — Customs-CGST joint operations on export-rebate cases are a major enforcement area. The data interface through ICEGATE makes such verification operationally efficient. From the taxpayer-side perspective, defence requires (a) consistent factual narrative across CGST and Customs tracks; (b) detailed documentation of actual exports — Shipping Bills, container records, bank realisations, foreign-buyer correspondence; (c) coordinated counsel — GST counsel and Customs counsel working in parallel; (d) anticipatory bail if criminal track is indicated.
Example 4 — Land revenue recovery via Collector for substantial GST default
Facts: A trading company in Lucknow has been adjudicated to owe Rs. 2.5 crore tax + interest + penalty under s. 74 — total demand Rs. 6 crore. Despite SCN-adjudication, appeals dismissed, and revisional rejection, the company has not paid. Bank accounts are exhausted under s. 79(1)(c) — only Rs. 50,000 recovered. The proper officer proceeds under s. 79(1)(f) for recovery as arrears of land revenue.
Step 1: Certification under s. 79(1)(f) — Proper officer prepares certificate specifying the amount due (Rs. 6 crore + interest accrued), the defaulter's name, the properties known to be held by the defaulter (commercial premises in Lucknow valued Rs. 4 crore; residential premises of director valued Rs. 1.5 crore). Certificate forwarded to District Collector, Lucknow.
Step 2: Collector's action — Collector receives certificate; treats the amount as arrears of land revenue under the UP Land Revenue Code (UPLR); issues notice to defaulter under UPLR; attaches commercial premises; conducts proceedings for sale through auction.
Step 3: Inter-officer cooperation under s. 72(1) — Collector requires Tehsildar, Patwari, and revenue inspectors to conduct property surveys, verify ownership, value the properties. These officers are within s. 72(1) — ‘officers engaged in the collection of land revenue, including village officers’ — and provide cooperation in the recovery chain.
Step 4: Sale and recovery — Auction conducted; commercial premises sold for Rs. 3.8 crore (recovered Rs. 3.8 crore); residential premises auctioned for Rs. 1.2 crore (recovered Rs. 1.2 crore). Total recovery Rs. 5 crore. Balance Rs. 1 crore + accumulated interest remains; further attachment of other properties identified.
Step 5: Defence positions for taxpayer — (i) Challenge the certificate under s. 79(1)(f) if any procedural irregularity (e.g., amount not properly determined; not signed by proper officer); (ii) Challenge the attachment of properties not actually owned by the defaulter (e.g., property in director's individual name where defaulter is the company — corporate veil generally protects directors unless lifted); (iii) Challenge the auction procedure if material irregularities; (iv) Negotiate settlement if practicable — compounding under s. 138 still available subject to deposit; arrangement with Collector for instalments on remaining amount.
Step 6: Practitioner takeaway — Once recovery proceeds under s. 79(1)(f), the recovery moves out of CGST officer's direct control and into Collector's domain. Procedural defences shift to the Land Revenue Code framework. Negotiation with Collector for property valuations, auction conditions, instalment arrangements is the practical course.
Result: Practitioner alignment — Land revenue recovery under s. 79(1)(f) is the ultimate recovery mechanism for substantial GST defaults. The s. 72(1) cooperation framework covers the entire recovery chain — Collector, Tehsildar, village officers. Taxpayer defence at this stage is procedural and practical — challenge specific irregularities, protect non-defaulter properties (particularly director / shareholder personal properties through corporate-veil protection), negotiate instalments / settlement with Collector.
Example 5 — Multi-agency coordination on suspected money-laundering case
Facts: A pharmaceutical exporter in Hyderabad is subject to coordinated investigation — CGST officer suspects ITC fraud and false export-rebate; Customs suspects under-valuation of imports; Income Tax suspects undisclosed income; ED suspects money laundering with Predicate Offence under PMLA based on the GST and Customs offences. The case requires multi-agency coordination.
Step 1: Initial trigger — DGGI investigation reveals suspected Rs. 10 crore ITC fraud and Rs. 5 crore false export-rebate claim. Information shared with Customs (DRI) and Income Tax (Investigation Wing). Predicate Offence under PMLA arises from the GST / Customs offences under their respective s. 132 provisions.
Step 2: Joint investigation framework — At CBIC level, joint investigation framework activated. CGST is lead authority for GST issues; DRI is lead for Customs issues; ED is lead for PMLA proceedings; Income Tax is lead for under-disclosed income proceedings. Inter-agency coordination meetings monthly.
Step 3: Information sharing — GST documents shared with DRI and ED; Customs documents shared with CGST and ED; Income Tax records sought; financial intelligence on bank trails shared with all agencies. Consolidated factual picture built jointly.
Step 4: Coordinated enforcement — Search under s. 67 CGST coordinated with search under Customs Act and search under s. 17 PMLA. Single coordinated operation; multiple authorisations under each statute. Police assistance under s. 72(1) for the entire multi-agency operation.
Step 5: Parallel proceedings — CGST proceedings under ss. 73/74 for tax demand and s. 132 for prosecution. Customs proceedings under Customs Act for valuation and prosecution. Income Tax proceedings for undisclosed income. PMLA proceedings for attachment of proceeds of crime, prosecution under s. 4 PMLA.
Step 6: Taxpayer-side response — Multi-counsel team — GST counsel, Customs counsel, IT counsel, PMLA / criminal counsel. Coordinated factual narrative across all tracks; consistent statements; avoid contradiction. Anticipatory bail under Cr.P.C. s. 438 from all relevant courts (PMLA Special Court has separate framework). Compounding evaluation for GST and Customs tracks where applicable.
Step 7: Practitioner caution — PMLA proceedings are particularly serious — attachment of properties under s. 5 PMLA possible immediately; provisional attachment confirmed by Adjudicating Authority within 180 days; prosecution under s. 4 PMLA with bail conditions under s. 45 PMLA (twin-condition framework). Defence to PMLA requires substantial proof of legitimacy of properties.
Result: Practitioner alignment — Multi-agency coordination cases are at the high end of enforcement intensity. The cooperation framework under s. 72(1) and beyond (informal CBIC-level coordination, ED interface through Predicate Offence framework) creates significant enforcement leverage. Taxpayer defence requires (a) multi-counsel team across tracks; (b) consistent factual narrative; (c) anticipatory bail across all relevant courts; (d) substantial documentation of legitimate sources of properties to defend PMLA attachment. Compounding under s. 138 may resolve GST track but does not terminate other tracks — PMLA proceedings continue based on the residual Predicate Offence.
PRACTITIONER PLANNING
• For large taxpayers — map all jurisdictional and inter-Departmental authorities that may potentially have interest in the taxpayer's operations: CGST, SGST, Customs, Income Tax, RBI, FEMA, SEZ, ED. Maintain awareness of activity across all.
• Verify GST allocation at the start of any case — Central or State? Notification 39/2018-CT framework. Allocation determines lead authority for cross-empowerment purposes.
• Track parallel proceedings carefully — CGST adjudication, IPC FIR (if any), Customs proceedings (if applicable), ED proceedings (if Predicate Offence triggered), Income Tax proceedings (if undisclosed income alleged). Each track has its own framework and timeline.
• Coordinate counsel across tracks — GST counsel for substantive GST proceedings; criminal counsel for IPC / s. 132 prosecution / PMLA; Customs counsel for Customs proceedings; IT counsel for Income Tax proceedings. Single coordinator across all tracks ensures consistent factual narrative.
• For multi-agency operations — anticipate police assistance and document the entire cooperation chain — officer names, ranks, roles, timing. Critical for writ defence.
• Section 6(2)(b) bar on parallel proceedings — strong defence against duplicate Central / State action on same subject-matter. Identify duplication early; respond with explicit jurisdictional objection.
• Customs-CGST joint operations on export-rebate or import-IGST cases — gather Shipping Bill / Bill of Entry data through Customs counsel; verify accuracy of CGST allegations against actual customs records.
• Land revenue recovery proceedings under s. 79(1)(f) — engage local counsel familiar with State Land Revenue Code; protect non-defaulter properties through corporate-veil arguments; negotiate with Collector for instalments / valuations.
• Banking-channel attachment under s. 79(1)(c) — verify procedural validity; challenge if pre-determination attachment; maintain alternative banking arrangements for business-continuity.
• Compounding under s. 138 — strategic exit for CGST track even if other tracks (PMLA, Customs, Income Tax) continue separately. Quantify tax + interest + penalty + compounding amount within 50%-150% bracket.
LITIGATION DEFENCE — KEY ATTACK POINTS
• Allocation jurisdiction — challenge proceedings by non-allocated authority. Cite Notification 39/2018-CT, Circular 1/1/2017-IGST, s. 6(2)(b) bar.
• Cross-empowerment conditions — challenge if cross-empowered officer exceeds notification conditions (e.g., very senior officer exercising jurisdiction reserved for lower level).
• Parallel proceedings — strong attack point on s. 6(2)(b) for duplicate Central and State action on same subject-matter.
• Police role compliance — for any arrest, demand DK Basu / Arnesh Kumar compliance from police as well as CGST officers.
• Customs data accuracy — for cases based on ICEGATE / Shipping Bill data, demand authenticated Customs records; verify against business's own records; challenge discrepancies.
• Joint operation documentation — demand records of inter-Departmental cooperation; identify gaps in advance authorisation, briefing, role-assignment.
• Land revenue procedure — challenge specific procedural irregularities under State Land Revenue Code; protect non-defaulter properties.
• Cross-track inconsistencies — identify inconsistencies between Central CGST and State SGST positions; use as attack point.
• PMLA Predicate Offence — challenge the underlying Predicate Offence (GST / Customs offence) to undermine PMLA proceedings; defence to underlying offence supports defence to PMLA.
• FIR by police for IPC offence — challenge if the police FIR is based solely on CGST officer's complaint without independent investigation; cite Cr.P.C. ss. 154-157 procedural framework.
• Writ remedies — for multi-agency coordination going outside statutory bounds, writ under Article 226 / 32 against the consolidated action; cite separation of powers and procedural irregularity.
