Imagine a manufacturer whose Electronic Credit Ledger shows:
Available ITC: ₹25 lakh
During investigation, DGGI forms a prima facie view that the manufacturer had wrongly availed ₹5 crore of ITC in earlier periods.
But most of that credit has already been utilised for payment of output tax.
The officer invokes Rule 86A of the CGST Rules, 2017.
What should happen?
One possibility is:
Existing ITC ₹25 lakh → blocked
But suppose the portal instead shows:
ITC allegedly ineligible: ₹5 crore
ITC presently available: ₹25 lakh
Negative blocked balance: ₹4.75 crore
The business subsequently makes perfectly genuine purchases and earns another ₹1 crore of ITC.
It still cannot use that credit.
Another ₹1 crore enters.
Still unusable.
Month after month, future genuine ITC is absorbed by the negative block until the entire ₹4.75 crore is notionally replenished.
No adjudication may yet have determined that the old ITC was actually wrong.
No final demand may exist.
Yet the taxpayer is compelled to discharge current output GST in cash.
The question is therefore much larger than:
Can the Department block ITC?
Of course Rule 86A authorises blocking in specified circumstances.
The real question is:
CAN RULE 86A BLOCK ITC THAT DOES NOT EXIST ON THE DATE OF THE ORDER?
And beneath that question lies an even deeper one:
CAN A TEMPORARY PROTECTIVE POWER BE USED TO ACHIEVE THE ECONOMIC EFFECT OF RECOVERY BEFORE ADJUDICATION?
A significant line of High Court decisions has answered that question in favour of taxpayers. Revenue carried several of those decisions to the Supreme Court. Most recently, on 18 June 2026, the Supreme Court declined to interfere with the Punjab & Haryana High Court's decision in M/s K.K. Alloys v. Union of India & Ors., while specifically leaving Revenue free to pursue other remedies for recovery according to law.
That qualification—“other remedies for recovery”—may contain the key to understanding the entire controversy.
WHAT EXACTLY IS RULE 86A?
Rule 86A was inserted into the CGST Rules with effect from 26 December 2019.
Its heading itself is revealing:
“Conditions of use of amount available in electronic credit ledger.”
Broadly stated, the Commissioner or an authorised officer not below the prescribed rank may, after recording reasons to believe that ITC available in the Electronic Credit Ledger has been fraudulently availed or is ineligible for one of the specified reasons, restrict debit of an amount equivalent to such credit.
The Rule contemplates situations such as:
- invoice issued by a non-existent supplier;
- invoice without receipt of goods/services;
- tax charged by supplier not paid to Government;
- recipient itself being non-existent;
- credit claimed without the prescribed invoice/debit note or supporting document.
The restriction is temporary. Under Rule 86A(3), it ceases to have effect after one year from imposition. CBIC's own guidelines describe the power as extraordinary and stress careful, non-mechanical exercise based on material evidence.
The statutory phrase that caused the litigation is:
“credit of input tax available in the electronic credit ledger…”
What does “available” mean?
Does it mean credit presently lying in the ECL?
Or does it include credit that was once availed, subsequently utilised and may have to be replaced by future credits?
That single word divided High Courts.
THE DIFFERENCE BETWEEN “AVAILED”, “AVAILABLE” AND “UTILISED” IS THE HEART OF THE CASE
This distinction was developed most carefully by the Delhi High Court in Best Crop Science Pvt. Ltd. v. Principal Commissioner, CGST, decided on 24 September 2024.
The Court separated three stages.
ITC is “availed”
when the taxpayer claims eligible input tax credit through the statutory return mechanism and it enters the Electronic Credit Ledger.
ITC is “available”
when the amount actually stands to the taxpayer's credit in that ledger.
ITC is “utilised”
when that available credit is used towards discharge of output tax liability in accordance with Sections 49, 49A and 49B.
The Court rejected the contention that credit once available years earlier remains “available” for purposes of Rule 86A after it has already been used.
That difference may be expressed mathematically:
AVAILED ITC − UTILISED ITC = AVAILABLE ITC
Rule 86A speaks of the third component:
AVAILABLE ITC
Revenue's broader interpretation effectively reads the Rule as though Parliament had written:
“credit which has at any time been availed, whether presently available or already utilised…”
Those are not the words actually used.
THE FIRST MAJOR TAXPAYER-FAVOURABLE DECISION: SAMAY ALLOYS
The Gujarat High Court directly confronted negative blocking in:
Samay Alloys India Pvt. Ltd. v. State of Gujarat
Special Civil Application No. 18059 of 2021
Decided: 3 February 2022
The taxpayer's ECL balance was Nil when Revenue sought to block ITC.
The Court held that availability of credit was a condition precedent to Rule 86A.
Its reasoning was straightforward:
Condition 1: ITC must be available in ECL.
Condition 2: competent officer must have reason to believe that such credit is fraudulent/ineligible.
Condition 3: reasons must be recorded in writing.
If no credit is available, the first jurisdictional condition fails.
Accordingly, insertion of a negative balance was held outside Rule 86A. The Gujarat High Court expressly ruled that there is no power to negatively block credit to be availed in future.
This distinction is critical:
RULE 86A CAN RESTRICT USE OF AN EXISTING ASSET.
But according to Samay Alloys:
IT CANNOT CREATE A FUTURE ASSET, ASSUME IT ALREADY EXISTS, AND FREEZE IT TODAY.
The Court also pointed out that Revenue was not left helpless.
If ITC had been wrongly availed and already utilised, the Department could initiate statutory demand/adjudication proceedings and use the recovery mechanisms Parliament had actually provided.
That becomes important later.
CBIC'S OWN 2021 GUIDELINES SUPPORT A NARROW AND CAREFUL EXERCISE
Even before Samay Alloys, CBIC issued detailed Guidelines dated 2 November 2021, File No. CBEC-20/16/05/2021-GST, specifically dealing with Rule 86A.
CBIC emphasised that:
- there must be reasons to believe;
- those reasons must arise from the grounds specifically contemplated by Rule 86A;
- there must be proper application of mind;
- blocking should not be mechanical;
- Rule 86A is an extraordinary remedy;
- material evidence, not mere subjective suspicion, must underlie the decision;
- the amount restricted should not exceed the amount believed to have been fraudulently availed/ineligible;
- because blocking affects working capital, investigation and adjudication should be completed expeditiously. (CBIC GST)
The Delhi High Court later relied on paragraphs 3.3.2 and 3.4.3 of these guidelines in Best Crop Science and concluded that the guidelines did not support Revenue's theory of unlimited negative blocking.
This produces an important administrative-law point:
RULE 86A WAS DESIGNED AS AN EMERGENCY PROTECTION DEVICE—not as an indefinite substitute for determination proceedings.
BUT THERE WAS A CONTRARY VIEW: R.M. DAIRY PRODUCTS
The taxpayer-favourable interpretation was not initially uniform.
In:
R.M. Dairy Products LLP v. State of U.P.
Writ Tax No. 434 of 2021
Allahabad High Court
Decided: 15 July 2021
2021 SCC OnLine All 1144
the Court took a materially different view.
It reasoned that Rule 86A does not itself recover tax.
Instead it creates, in substance, a protective lien.
Even where no positive ITC remains in the ledger when the order is issued, subsequent ITC can become subject to that lien up to the amount specified in the Rule 86A order.
The Court drew a distinction between:
blocking / lien
and
actual appropriation / recovery.
According to this approach, future credit may be immobilised, but Government does not obtain title to it until proper adjudication/recovery follows.
This is Revenue's strongest jurisprudential argument.
Suppose:
Fraudulent ITC allegedly availed = ₹10 crore
Entire ₹10 crore immediately utilised
ECL on date of detection = Nil
If Rule 86A cannot operate merely because the taxpayer used the credit quickly enough, Revenue argues that the very persons most likely to have fraudulently cycled ITC will escape the preventive mechanism.
Thus:
Fraudulent credit claimed Monday
↓
Utilised Tuesday
↓
Investigation begins Wednesday
↓
ECL Nil
↓
Rule 86A powerless?
The Allahabad High Court considered that outcome inconsistent with the protective purpose of the Rule.
It is an intuitively powerful argument.
But intuitive purpose and statutory power are not necessarily the same thing.
CALCUTTA HIGH COURT: “NEGATIVE BLOCKING” IS NOT EVEN A STATUTORY EXPRESSION
The contrary line was reinforced in:
Basanta Kumar Shaw, proprietor of N.M.D. Engineering Works v. Assistant Commissioner of Revenue
MAT 976 of 2022
Calcutta High Court
Decided: 28 July 2022
2022 SCC OnLine Cal 4544
The Calcutta High Court expressly disagreed with Samay Alloys.
It reasoned that “negative blocking” was merely terminology commonly used by taxpayers; the expression itself does not occur in Rule 86A.
The Court emphasised the words:
“has been fraudulently availed or is ineligible”
and treated “available” as capable of referring back to ITC that had earlier been availed.
It held that Rule 86A did not require the ECL to contain sufficient positive balance on the date of blocking. (Casemine)
So two competing theories emerged.
Theory A — Gujarat approach
“Available” means presently available.
No current credit → nothing Rule 86A can block.
Theory B — Allahabad/Calcutta approach
“Has been availed” looks backward.
Fraudulent past ITC can support a lien upon future credits even if today's balance is nil.
That was the genuine High Court conflict.
BEST CROP SCIENCE: THE DELHI HIGH COURT GOES BACK TO FIRST PRINCIPLES
The Delhi High Court's 2024 decision in Best Crop Science Pvt. Ltd. v. Principal Commissioner, CGST, W.P.(C) 10980/2024 and connected petitions, is perhaps the most analytically developed judgment in the taxpayer-favourable line.
The Court did not merely say that negative blocking seemed harsh.
It reconstructed the entire statutory mechanism.
It examined:
- Section 41 — availment of ITC;
- Section 49 — amount available in ECL;
- Sections 49A and 49B — utilisation;
- Section 50 — consequences of wrong availment/utilisation;
- Rules governing the ECL;
- Rule 86A;
- CBIC's 2021 guidelines;
- Sections 73/74 for determination;
- Section 83 for provisional attachment.
The Court concluded that when Rule 86A refers to credit “available in the electronic credit ledger”, it refers to the amount actually lying to the taxpayer's credit in the ECL. It specifically rejected the idea that the expression means credit that was available at some earlier time before being utilised.
The Court then made a more profound distinction.
Rule 86A does not authorise the officer to debit the ECL.
It authorises him to:
“not allow debit”
That is the difference between:
FREEZE
and
TAKE.
The former is temporary preservation.
The latter begins to resemble recovery.
WHY “NEGATIVE BLOCKING” CAN BECOME DE FACTO RECOVERY
The Delhi High Court identified the economic reality.
Assume:
ECL currently available: ₹10 lakh
Historical ITC suspected: ₹1 crore
If Government blocks ₹1 crore negatively, then future genuine credit of ₹90 lakh has to accumulate before the taxpayer can use a single rupee of it.
During that period, current output GST must be discharged through cash.
Economically:
OLD ITC ALLEGATION
↓
FUTURE GENUINE ITC FROZEN
↓
CURRENT OUTPUT TAX PAID IN CASH
↓
₹90 LAKH ADDITIONAL CASH OUTFLOW
The Department has not formally “recovered” ₹90 lakh.
But the taxpayer has effectively been forced to finance the alleged past liability before adjudication.
The Delhi High Court therefore reasoned that such construction would transform Rule 86A into an order requiring the taxpayer to replenish past disputed ITC with future valid ITC. That begins to resemble recovery, which belongs to the statutory determination and recovery machinery, not Rule 86A.
This is perhaps the most powerful conceptual proposition in the entire controversy:
A RESTRICTION ON USING SOMETHING YOU POSSESS IS A FREEZE.
But:
A REQUIREMENT THAT FUTURE PROPERTY FIRST SATISFY AN OLD DISPUTED AMOUNT LOOKS LIKE A RECOVERY MECHANISM.
THE WORD “EQUIVALENT” DOES NOT SOLVE REVENUE'S PROBLEM
Revenue has repeatedly relied upon the phrase:
“an amount equivalent to such credit”
The argument is:
Parliament did not say the officer must freeze the exact tainted credit.
It said an equivalent amount.
Therefore, any equivalent future credit may be blocked.
The courts rejecting negative blocking have answered this in two stages.
First, the phrase “equivalent to such credit” appears in the consequence portion of Rule 86A.
Before reaching that consequence, the jurisdictional condition must exist:
credit of input tax available in the ECL
which the officer believes is fraudulent/ineligible.
A consequence cannot manufacture the condition required to invoke the Rule.
Second, ITC in the ECL is fungible.
Once ₹10 lakh legitimate ITC and ₹5 lakh allegedly tainted ITC enter the same ECL, they are not individually labelled coins.
Hence the officer is permitted to block an equivalent amount.
The word “equivalent” solves the problem of fungibility.
It does not necessarily authorise attachment of assets that do not yet exist.
Thus:
“EQUIVALENT” IDENTIFIES QUANTUM.
It does not automatically enlarge:
THE SUBJECT MATTER OVER WHICH RULE 86A OPERATES.
FUTURE ITC MAY BE COMPLETELY UNCONNECTED WITH THE ALLEGED FRAUD
The Bombay High Court sharpened this point in Hemang Bipin Varaiya v. State of Maharashtra, W.P. No. 3452 of 2026, decided on 18 March 2026.
The Court followed the Gujarat and Delhi line.
It observed that ITC accruing after the blocking order may not have any taint of fraud or ineligibility whatsoever.
Why should ITC generated from:
- a completely different supplier,
- a later tax period,
- actual receipt of goods,
- genuine payment,
- proper invoice,
- correct tax discharge,
automatically become frozen because some earlier ITC is under investigation?
The Bombay High Court held that Rule 86A, as presently drafted, permits blocking only to the extent of credit actually available when the blocking power is exercised.
That gives the controversy a powerful property-law dimension:
YESTERDAY'S ALLEGEDLY TAINTED CREDIT DOES NOT AUTOMATICALLY TAINT TOMORROW'S GENUINE CREDIT.
Unless the statute expressly creates such a charge or lien.
THE BOMBAY HIGH COURT ALSO CONFRONTED THE HIGH COURT SPLIT DIRECTLY
In Hemang Bipin Varaiya, the Bombay High Court expressly considered:
- Samay Alloys — Gujarat;
- Best Crop Science — Delhi;
- Karuna Rajendra Ringshia — Delhi;
- Laxmi Fine Chem — Telangana;
- the contrary Basanta Kumar Shaw — Calcutta;
- and the competing purposive approach.
It chose the Gujarat/Delhi interpretation.
Its reasoning is particularly valuable:
Courts cannot repair what may be regarded as defective legislative drafting merely because the broader interpretation appears more efficient for Revenue.
The intention of the rule-maker must primarily be derived from the language actually used.
The Court expressly preferred the literal reading of “available” over an interpretation based on presumed legislative purpose.
That creates a classic tax-law proposition:
REVENUE PROTECTION IS A LEGITIMATE OBJECT.
But:
LEGITIMATE OBJECT ≠ UNLIMITED STATUTORY POWER.
K.K. ALLOYS: THE CONTROVERSY REACHES PUNJAB & HARYANA
The issue then came before the Punjab & Haryana High Court in:
M/s K.K. Alloys v. Union of India & Ors.
CWP No. 26150 of 2025
Decision dated 19 November 2025
The question was framed very precisely:
Whether Rule 86A permits the Commissioner or authorised officer to block a taxpayer's ECL by an amount exceeding the credit available at the time of the order?
The taxpayer's ledger had been negatively blocked by more than ₹11.60 crore, followed by another amount of approximately ₹3.19 lakh.
The Punjab & Haryana High Court noted the divergent authorities but endorsed the Gujarat, Delhi, Telangana and Bombay line rather than the Allahabad/Calcutta approach.
It reiterated that:
availability of ITC is a condition precedent;
Rule 86A merely allows restriction of debit;
it does not authorise debit entries creating artificial negative balances;
and permanent recovery belongs to the demand/adjudication machinery.
THEN THE SUPREME COURT WAS APPROACHED
Revenue challenged the result in Union of India & Ors. v. M/s K.K. Alloys, SLP (Civil) Diary No. 33451/2026.
On 18 June 2026, the Supreme Court declined to interfere under Article 136 and dismissed the Special Leave Petitions.
Significantly, however, it kept open:
Revenue's other remedies for recovery in accordance with law.
That was not the first time the Supreme Court had declined to interfere with the Delhi line.
In Deputy Director, DGGI v. Kings Security Guard Services Pvt. Ltd., the Supreme Court dismissed Revenue's SLP on 16 May 2025, again preserving other lawful recovery remedies.
Likewise, Revenue's challenge arising from Karuna Rajendra Ringshia v. Commissioner of CGST was dismissed by the Supreme Court in July 2025, with the other lawful recovery remedies expressly preserved.
There is therefore a striking pattern:
NEGATIVE BLOCKING SET ASIDE
↓
REVENUE APPROACHES SUPREME COURT
↓
NO INTERFERENCE UNDER ARTICLE 136
↓
BUT LAWFUL RECOVERY REMEDIES PRESERVED
That repeated formulation reinforces the conceptual separation between:
BLOCKING
and
RECOVERY.
BUT A CRITICAL LEGAL CAUTION: THE SUPREME COURT HAS NOT YET DELIVERED A REASONED ARTICLE 141 JUDGMENT ON RULE 86A NEGATIVE BLOCKING
This distinction must be maintained.
It would be inaccurate to say:
“The Supreme Court has finally declared under Article 141 that negative blocking is illegal.”
The recent Supreme Court orders are essentially dismissals of Special Leave Petitions at the Article 136 stage.
The Court did not grant leave and deliver a reasoned appellate judgment interpreting every phrase of Rule 86A.
The Constitution Bench-line principle in Kunhayammed v. State of Kerala, (2000) 6 SCC 359 is that a non-speaking dismissal of an SLP does not result in merger and does not, merely by itself, constitute a declaration of law under Article 141.
Therefore the legally precise position is:
The detailed ratios presently come primarily from the High Courts.
The Supreme Court has repeatedly declined to interfere with taxpayer-favourable decisions and has preserved Revenue's independent recovery remedies.
That is commercially and judicially significant.
But it is not identical to a full reasoned Supreme Court precedent deciding the conflict under Article 141.
This distinction becomes especially relevant because a contrary High Court line—principally R.M. Dairy Products and Basanta Kumar Shaw—exists.
SO IS THE HIGH COURT CONFLICT COMPLETELY DEAD?
Not quite in jurisprudential theory.
The taxpayer-favourable view now has impressive weight:
Gujarat
→ Samay Alloys
Delhi
→ Best Crop Science, Karuna Ringshia, Kings Security
Telangana
→ Laxmi Fine Chem
Punjab & Haryana
→ Shyam Sunder Strips, K.K. Alloys
Bombay
→ Rawman Metal & Alloys, Hindustan Steel, ISKCON Steel Traders, Hemang Bipin Varaiya
and several Revenue SLPs have failed at the Supreme Court threshold.
But the contrary reasoning remains visible in:
Allahabad
→ R.M. Dairy Products LLP
and
Calcutta
→ Basanta Kumar Shaw / N.M.D. Engineering Works.
Indeed, an Allahabad High Court order in 2025 noted that its earlier R.M. Dairy Products decision regarded the negative lien as permissible, while another Bench had referred the question to a Larger Bench.
So the better description is:
THE JUDICIAL TREND IS NOW STRONGLY AGAINST NEGATIVE BLOCKING, BUT A FULL REASONED SUPREME COURT RESOLUTION OF THE CONFLICT WOULD STILL HAVE DISTINCT PRECEDENTIAL VALUE.
RULE 86A IS NOT AN ADJUDICATION PROVISION
This may be the deepest statutory point.
When Rule 86A is invoked, the Commissioner needs only “reasons to believe” at the preliminary stage.
That means the officer has not yet finally determined:
“₹5 crore ITC is legally inadmissible.”
He has only formed the statutory belief necessary to justify a temporary protective measure.
The stages are different:
STAGE 1 — RULE 86A
Prima facie belief
↓
Temporary restriction
Then:
STAGE 2 — SECTIONS 73 / 74 / 74A
Notice
↓
Evidence
↓
Reply
↓
Hearing
↓
Determination
Then, if legally recoverable:
STAGE 3 — RECOVERY
Statutory collection machinery
The Delhi High Court in Best Crop Science expressly stressed that Rule 86A is neither an assessment nor a recovery mechanism. If ITC was wrongly availed or utilised, determination must proceed through the statutory provisions applicable to that liability. (Indian Kanoon)
For FY 2024-25 onward, that determination architecture is now principally located in Section 74A, rather than the earlier Sections 73 and 74 dual structure.
Therefore:
REASONS TO BELIEVE MAY JUSTIFY PRESERVATION.
But:
REASONS TO BELIEVE ARE NOT A SUBSTITUTE FOR DETERMINATION.
THE “₹100 CRORE FAKE ITC” COUNTERARGUMENT
A serious analysis must confront Revenue's strongest objection.
Suppose investigators uncover prima facie evidence that a taxpayer received ₹100 crore of completely fictitious ITC.
The taxpayer has already utilised ₹99 crore.
Only ₹1 crore remains in its ECL.
Under the restrictive interpretation:
Rule 86A can immediately block only ₹1 crore.
Revenue asks:
Why should the taxpayer who rapidly utilised fraudulent credit be better placed than one who left it sitting in the ledger?
That question has considerable force.
But there are two possible responses.
First, the apparent enforcement gap cannot necessarily be filled by judicially rewriting Rule 86A.
If Government considers the power inadequate, the Rule can be amended.
Second, Revenue is not actually without remedies.
Depending upon statutory conditions, it may:
- proceed with determination under Sections 73/74 or Section 74A;
- invoke interest/penalty provisions;
- use provisional attachment under Section 83 where legally available;
- take registration-related action where warranted;
- proceed against fake invoice networks;
- eventually recover determined dues under the statutory machinery.
Samay Alloys, Best Crop Science and Hemang Bipin Varaiya all emphasise that refusing negative blocking does not immunise wrongful ITC.
Therefore:
NO NEGATIVE BLOCKING ≠ NO RECOVERY.
It means:
RECOVERY MUST USE THE RECOVERY LAW.
THIS IS THE SAME JURISPRUDENTIAL PROBLEM SEEN IN COERCIVE DRC-03 RECOVERY
There is an interesting doctrinal parallel.
In DRC-03 cases, the issue is:
Search power exists.
But:
Can search become recovery?
In Rule 86A cases:
ITC-blocking power exists.
But:
Can blocking become recovery?
In provisional attachment cases:
Revenue-protection power exists.
But:
Can attachment become punishment before adjudication?
The unifying constitutional principle is:
ONE STATUTORY POWER CANNOT BE USED AS A SUBSTITUTE FOR ANOTHER MERELY BECAUSE IT IS FASTER.
GST law deliberately separates:
INVESTIGATION
PROVISIONAL PROTECTION
ADJUDICATION
RECOVERY
Collapsing them into one administrative action changes the architecture Parliament created.
RULE 86A AND SECTION 83: TWO DIFFERENT REVENUE-PROTECTION TOOLS
This distinction also answers an important objection.
Why should Revenue not be permitted to freeze future ITC when it can sometimes provisionally attach property under Section 83?
Precisely because Parliament created different provisions with different triggers, objects and safeguards.
Rule 86A concerns:
use of available ITC in the Electronic Credit Ledger
Section 83 concerns:
provisional attachment of property, subject to the statutory conditions governing that extraordinary power.
One cannot enlarge Rule 86A because another statutory provision may be inconvenient or subject to stricter safeguards.
This is the same logic as:
You cannot use Section 67 search powers to achieve Section 79 recovery merely because Section 79 requires more procedural steps.
A carefully structured statute is defined as much by the boundaries between powers as by the powers themselves.
THE ONE-YEAR LIMIT SHOWS RULE 86A IS TEMPORARY BY DESIGN
Rule 86A(3) says that the restriction ceases after one year.
That provision is not cosmetic.
It demonstrates the provisional character of the power.
The logic is:
Revenue sees prima facie risk
↓
temporarily secures available credit
↓
investigates quickly
↓
adjudicates
↓
either recovers lawfully or releases the restriction
CBIC's 2021 guidelines expressly recognise the adverse working-capital effect and say investigation/adjudication should be completed at the earliest within the restriction period. (Indian Kanoon)
If the Department could simply keep a ₹10 crore negative lien into which future credits continually disappear, the one-year temporary character would risk becoming economically distorted.
Recent Bombay High Court cases have also stressed that blocking cannot lawfully continue beyond the one-year statutory period.
CAN THE DEPARTMENT ISSUE A NEW RULE 86A ORDER AFTER ONE YEAR?
This is likely to become a further litigation frontier.
Suppose:
1 January 2025
₹5 crore ITC blocked.
Under Rule 86A(3), restriction expires:
31 December 2025 / after one year
Then on:
2 January 2026
the officer issues another blocking order substantially on the same material.
Has Rule 86A(3) been respected formally but defeated substantively?
If entirely new evidence, fresh transactions or a distinct fraudulent credit chain arises, a fresh Rule 86A exercise may stand differently.
But repetitive re-blocking based on the same old reasons would invite an argument that the administration is doing indirectly what Rule 86A(3) prevents directly.
The expiry provision would otherwise become almost meaningless.
This is an area worth watching.
“REASONS TO BELIEVE” IS NOT “REASONS TO SUSPECT”
Negative blocking is only one Rule 86A controversy.
Even where sufficient ITC genuinely exists in the ledger, the officer must still satisfy the statutory threshold.
CBIC itself says the Rule should not be used mechanically and that the belief must be founded on material evidence rather than purely subjective suspicion. (CBIC GST)
This matters where blocking occurs merely because:
- supplier is under investigation;
- supplier's registration was subsequently cancelled;
- another entity somewhere in the chain is allegedly bogus;
- GSTR-2B mismatch exists;
- intelligence flags an invoice pattern.
Those matters may justify investigation.
But Rule 86A requires the authorised officer personally to form the legally required belief on relevant material.
A vendor-side allegation cannot automatically become recipient-side culpability.
The Telangana High Court has also emphasised natural justice and adequate reasons in Rule 86A blocking cases, rejecting arbitrary restriction unsupported by the required procedural fairness.
Thus even after negative blocking disappears, Rule 86A litigation will remain alive through:
WHO formed the belief?
On what evidence?
Was the taxpayer's ITC specifically connected to the statutory grounds?
Were reasons actually recorded?
Was the correct authorised officer involved?
DOES RULE 86A REQUIRE A PRIOR SHOW-CAUSE NOTICE?
This is another subtle issue.
Because Rule 86A is designed as an emergency protective mechanism, the Delhi High Court in Best Crop Science recognised that a prior SCN is not necessarily required before the initial blocking order.
That makes sense.
If Revenue had to:
issue notice,
wait for reply,
grant hearing,
decide objections,
and only then freeze suspected credit,
the credit could disappear before the protective action was completed.
But absence of a mandatory prior SCN does not mean:
absence of accountability.
The officer must still:
- possess the statutory authority;
- form reasons to believe;
- record those reasons;
- confine action to Rule 86A's enumerated circumstances;
- restrict only the permissible amount;
- reconsider if conditions cease;
- respect the one-year limit;
- and proceed expeditiously toward actual adjudication.
(Indian Kanoon)
Emergency power means speed.
It does not mean unreviewable discretion.
NEGATIVE BLOCKING CREATES A STRANGE “FUTURE PROPERTY” PROBLEM
Consider another illustration.
On 1 April:
Taxpayer's ECL = Nil
Revenue believes an old ₹2 crore credit claim was fraudulent.
It places:
–₹2 crore
in the ledger.
On 15 April, the taxpayer genuinely purchases raw material worth ₹10 crore and lawfully earns ₹1.8 crore ITC.
Question:
Was that ₹1.8 crore fraudulent?
No.
Was it ineligible?
No.
Did it even exist when the Rule 86A satisfaction was recorded?
No.
Yet the negative-block theory automatically immobilises it.
This creates a conceptual disconnect between:
THE CREDIT ABOUT WHICH THE OFFICER FORMED “REASONS TO BELIEVE”
and
THE CREDIT ACTUALLY BEING FROZEN.
Under a literal reading of Rule 86A, those should ordinarily be connected.
The Bombay High Court's 2026 reasoning highlights exactly this problem: future ITC may be entirely clean and unrelated to whatever prompted the earlier Rule 86A action.
CAN RULE 86A CREATE A STATUTORY LIEN?
The Allahabad/Calcutta line effectively conceptualised Rule 86A as a lien securing Revenue's interest.
But this itself raises a fundamental question:
Where does the Rule use the word “lien”?
A lien is a legally significant proprietary restraint.
If the rule-maker intended to create:
a floating statutory charge over all future ITC until an historic amount is replenished
one might expect clearer language.
Instead Rule 86A speaks of:
not allowing debit of an amount equivalent to such credit in the ECL.
That sounds structurally more like freezing an existing balance than creating a floating charge over future property.
This is why the Delhi/Bombay/Gujarat approach increasingly prevailed.
The question is not whether a lien would be useful.
It is:
DID THE RULE-MAKER ACTUALLY CREATE ONE?
THE TAXING-STATUTE PRINCIPLE MATTERS
The Bombay High Court in Hemang Bipin Varaiya relied on the orthodox principle that fiscal statutes cannot be expanded on presumed legislative intention where the language does not confer the power.
That principle operates symmetrically.
Courts cannot give taxpayers an exemption because it appears equitable.
But equally:
Revenue cannot acquire a power because it appears administratively desirable.
The Court emphasised that tax and equity are strangers and statutory boundaries cannot be expanded by inference or analogy.
That produces a useful formulation:
PURPOSE CAN HELP INTERPRET POWER.
But:
PURPOSE CANNOT CREATE POWER.
WHAT DOES THE SUPREME COURT'S “OTHER REMEDIES FOR RECOVERY ARE KEPT OPEN” REALLY TELL US?
This sentence appears in several Rule 86A SLP dismissals.
It deserves attention.
If negative blocking itself were simply another lawful method of recovering previously utilised ITC, why repeatedly preserve other recovery remedies?
The wording is at least consistent with the High Court distinction:
RULE 86A
preserve presently available credit
versus
SECTIONS 73 / 74 / 74A + RECOVERY PROVISIONS
determine and recover wrongly availed/utilised credit
The Supreme Court's short orders do not create a detailed Article 141 exposition.
But their refusal to interfere while expressly preserving ordinary recovery routes certainly reinforces the practical separation between the two mechanisms.
DOES THE DECISION LET FRAUDSTERS ESCAPE?
No.
This misconception should be rejected.
Suppose Revenue ultimately proves that ₹5 crore of ITC was obtained using fictitious invoices.
Negative blocking being impermissible does not make that ₹5 crore legitimate.
Revenue can still establish:
wrongful availment
↓
wrongful utilisation
↓
interest
↓
fraud penalty where statutory ingredients exist
↓
recovery
and, in appropriate circumstances, other statutory consequences.
The taxpayer-favourable cases decide only:
WHICH STATUTORY TOOL MAY BE USED AT WHICH STAGE.
They do not convert fraudulent credit into valid credit.
This distinction is exactly analogous to criminal procedure:
Evidence may prove guilt.
But guilt does not retrospectively validate an unlawful procedure.
Similarly:
ULTIMATE TAX LIABILITY DOES NOT EXPAND RULE 86A RETROSPECTIVELY.
THE FIVE-QUESTION RULE 86A TEST
Every Rule 86A order should, in my assessment, now be tested against five sequential questions.
QUESTION 1 — IS THERE CREDIT ACTUALLY AVAILABLE IN THE ECL?
If ECL is nil, the dominant recent High Court view says negative blocking is impermissible.
QUESTION 2 — IS THE OFFICER LEGALLY AUTHORISED?
Rule 86A confers the power only upon the Commissioner or properly authorised officer of the prescribed rank.
QUESTION 3 — ARE THERE RECORDED “REASONS TO BELIEVE”?
Not generic suspicion.
Not simply:
“supplier found risky”.
The reasons should connect the taxpayer's ITC to one of Rule 86A's prescribed grounds.
QUESTION 4 — DOES THE BLOCK EXCEED THE PERMISSIBLE QUANTUM?
Even if ₹20 crore exists in the ECL, an officer who suspects only ₹3 crore cannot ordinarily freeze ₹20 crore under the Rule.
QUESTION 5 — HAS ONE YEAR EXPIRED?
If yes, Rule 86A(3) itself says the restriction ceases.
This test separates:
LAWFUL EMERGENCY PROTECTION
from
ADMINISTRATIVE PRE-ADJUDICATION PUNISHMENT.
AN EVEN DEEPER SIXTH QUESTION: WHAT EXACTLY IS THE DEPARTMENT TRYING TO ACHIEVE?
This is perhaps the most useful litigation question.
Ask:
Is the Department trying to prevent presently available suspicious ITC from disappearing?
That is classic Rule 86A territory.
Or:
Is the Department trying to recover ITC already consumed months or years ago?
That is materially different.
If the second is the real object, the correct statutory route ordinarily lies through determination and recovery, not through artificially freezing future good credit.
Thus:
OBJECT OF ACTION CAN REVEAL MISUSE OF POWER.
A statutory power described as “blocking” should not be judged merely by the label placed upon the portal entry.
One should examine its actual legal and economic effect.
RULE 86A VERSUS RECOVERY — A SIMPLE EXAMPLE
Assume:
January
Taxpayer avails disputed ITC: ₹100
February
Taxpayer utilises: ₹100
ECL becomes:
₹0
March
Department discovers alleged fraud.
Under a negative-block theory:
March Rule 86A entry = –₹100
April
Taxpayer genuinely earns new ITC:
₹40
But usable credit:
₹0
Negative balance becomes:
–₹60
May
Another genuine ₹60 credit arises.
Usable:
₹0
Negative balance becomes:
₹0
What actually happened economically?
The Department suspected a January liability.
By May, ₹100 of unrelated later credit has been consumed in servicing that suspicion.
No final adjudication was necessarily required.
That is why taxpayers describe negative blocking as:
RECOVERY BY LEDGER ARCHITECTURE.
The courts disallowing the practice regard that outcome as beyond the temporary protective character of Rule 86A.
THERE IS ALSO AN ARTICLE 300A DIMENSION — BUT IT SHOULD BE USED CAREFULLY
Taxpayers sometimes describe ITC as property protected by Article 300A.
There is support for treating lawfully accrued/utilisable credit as economically valuable, but one must avoid overstatement because the Supreme Court has repeatedly characterised ITC as a statutory benefit/right governed by legislative conditions, rather than an unconditional constitutional entitlement.
Therefore the stronger Rule 86A challenge does not require saying:
“ITC can never be restricted because it is absolute property.”
That argument is unnecessarily broad.
The better argument is:
Once Parliament and the Rules confer a statutory credit and prescribe the exact circumstances in which its use may temporarily be restrained, executive action must remain within those statutory circumstances.
That is much harder to answer.
A MORE FUNDAMENTAL DELEGATED-LEGISLATION QUESTION
There is another layer which merits deeper thought.
Rule 86A itself is subordinate legislation.
It operates under the CGST Act.
A Rule cannot casually create a recovery architecture substantially beyond the parent statute.
If Rule 86A were interpreted as creating an indefinite or floating lien over future genuine credits, one might ask:
Where in the Act is the statutory foundation for that prospective charge?
The broader the interpretation of Rule 86A becomes, the more important its anchoring in the parent Act becomes.
The narrow interpretation avoids much of that difficulty because it treats the Rule as exactly what it appears to be:
a temporary restriction upon use of credit currently available in the ledger.
WHAT SHOULD REVENUE DO WHEN THE ECL IS NIL?
The taxpayer-favourable jurisprudence does not require Revenue to sit idle.
A legally cleaner sequence would be:
Investigation detects allegedly wrongful historical ITC
↓
Current ECL checked
↓
If available:
Rule 86A may protect qualifying available credit
↓
For the balance already utilised:
issue proper statutory proceedings
↓
determine liability
↓
where statutory requirements exist:
use Section 83 or other protective mechanisms
↓
after liability becomes recoverable:
recover under the Act
This sequence preserves both interests:
Revenue is protected
and
adjudication is not bypassed.
THE CASE-LAW MAP
The jurisprudence can presently be understood as follows:
| Case | Court / Date | Core proposition |
|---|---|---|
| R.M. Dairy Products LLP v. State of U.P. | Allahabad HC, 15.07.2021 | Rule 86A can operate as a lien against future credit even where current balance is nil |
| Samay Alloys India Pvt. Ltd. v. State of Gujarat | Gujarat HC, 03.02.2022 | Credit must actually be available; negative blocking/future blocking impermissible |
| Basanta Kumar Shaw / N.M.D. Engineering Works | Calcutta HC, 28.07.2022 | Disagreed with Samay Alloys; positive current balance not necessary |
| Best Crop Science Pvt. Ltd. v. Principal Commissioner | Delhi HC, 24.09.2024 | “Available” means actually lying in ECL; Rule 86A is preventive, not recovery machinery |
| PMW Metal & Alloys Pvt. Ltd. v. Union of India | Gujarat HC, 20.09.2024 | Reaffirmed Samay Alloys; negative blocking impermissible |
| Karuna Rajendra Ringshia v. Commissioner CGST | Delhi HC, 21.10.2024 | Followed Best Crop Science; negative block lifted |
| Kings Security Guard Services Pvt. Ltd. | Delhi HC, 04.12.2024 | Followed taxpayer-favourable Rule 86A interpretation |
| SC SLP — Kings Security | Supreme Court, 16.05.2025 | Revenue SLP dismissed; other recovery remedies preserved |
| SC SLP — Karuna Ringshia | Supreme Court, July 2025 | No Article 136 interference; lawful recovery remedies preserved |
| Rawman Metal & Alloys / Hindustan Steel / related cases | Bombay HC, 2025 | Negative blocking beyond available credit rejected |
| K.K. Alloys v. Union of India | Punjab & Haryana HC, 19.11.2025 | Blocking cannot exceed ITC actually available |
| Hemang Bipin Varaiya v. State of Maharashtra | Bombay HC, 18.03.2026 | Future clean ITC cannot be caught by negative blocking under present Rule |
| Union of India v. K.K. Alloys | Supreme Court, 18.06.2026 | Revenue SLP dismissed; ordinary recovery remedies kept open |
The trend is therefore unmistakable, even while the technical Article 141 caveat surrounding SLP dismissals should be preserved.
THE DEEPER JURISPRUDENTIAL PRINCIPLE
The entire debate can be reduced to four statutory verbs:
AVAILED
Credit claimed.
↓
AVAILABLE
Credit presently standing in ECL.
↓
UTILISED
Credit used to discharge output tax.
↓
RECOVERED
Wrongful credit legally recouped after statutory process.
Rule 86A operates primarily at the AVAILABLE stage.
The controversy arose because administration attempted to use it retrospectively against credit already UTILISED, by capturing credit that would become AVAILABLE in the future.
That is why the taxpayer-favourable decisions insist upon keeping these concepts separate.
THE PRINCIPLE: A POWER CAN ONLY OPERATE ON THE LEGAL OBJECT PARLIAMENT GAVE IT
Suppose a statute authorises Government to:
freeze money standing in Account X.
The power necessarily presupposes that money exists in Account X.
It is conceptually different from a power saying:
all money which may enter Account X in future shall stand charged until an earlier suspected liability is satisfied.
The second is a floating statutory charge.
It is a materially stronger power.
Rule 86A expressly contains the first architecture.
Whether it contains the second has been the entire dispute.
The dominant current judicial answer is:
No.
A court should not convert one into the other merely because the second would be more effective for enforcement.
RULE 86A IS NOT A TIME MACHINE
Perhaps the simplest way to explain the principle is:
RULE 86A CAN LOOK AT WHY PRESENT CREDIT WAS AVAILED.
But:
IT CANNOT TRAVEL INTO THE FUTURE AND BLOCK CREDIT WHICH HAS NOT YET COME INTO EXISTENCE.
Nor can it travel backwards and undo an already completed utilisation merely by creating a negative number in the portal.
If historical utilisation was wrongful, Parliament has created a demand and recovery mechanism for exactly that situation.
THE PORTAL CANNOT CREATE A POWER THE RULE DOES NOT
This is another recurring problem in digital tax administration.
The GST portal may technically permit an officer to enter a negative block.
But:
SOFTWARE CAPABILITY ≠ STATUTORY AUTHORITY.
The portal is subordinate to the law.
It cannot reverse the hierarchy.
The correct sequence is:
CGST ACT
↓
CGST RULES
↓
CBIC GUIDELINES
↓
GST PORTAL FUNCTIONALITY
Not:
PORTAL ALLOWS IT
↓
THEREFORE LAW MUST PERMIT IT
That principle reaches far beyond Rule 86A.
It applies to every electronically administered tax power.
WHAT DOES THIS MEAN FOR TAXPAYERS TODAY?
Where an Electronic Credit Ledger has been negatively blocked, the taxpayer should examine at least:
The ECL balance on the exact date/time of blocking.
The amount allegedly fraudulently availed.
The amount actually blocked.
Whether the blocking produced a negative balance.
Whether the authorised officer recorded reasons to believe.
Whether those reasons relate to one of Rule 86A(1)(a)-(d)'s statutory grounds.
Whether the taxpayer has been given the recorded reasons or sufficient basis to challenge them.
Whether one year has expired.
Whether future ITC unrelated to the alleged transactions is being immobilised.
Whether adjudication under Sections 73/74/74A has even commenced.
Those facts can determine whether a case concerns legitimate Rule 86A protection or an impermissible substitute for recovery.
WHAT THE JUDGMENTS DO NOT SAY
The taxpayer-friendly decisions do not establish:
every Rule 86A order is illegal;
a prior adjudication is required before any blocking;
fraud must already be finally proved;
ITC is an unconditional constitutional property right;
Revenue cannot recover wrong ITC once it has been utilised;
fake-invoice taxpayers are protected from recovery.
What they establish much more narrowly is:
POWER MUST REMAIN WITHIN ITS STATUTORY OBJECT.
That is a stronger and more sustainable proposition.
THE NEXT LITIGATION FRONTIER
Even after the negative-blocking question, several issues remain ripe for litigation:
Can Rule 86A be repeatedly renewed after one year?
How detailed must “reasons to believe” be?
Must those reasons be communicated?
Can recipient ITC be blocked solely because a supplier is under investigation?
What evidentiary nexus is necessary between taxpayer and fraudulent supplier?
Can Rule 86A coexist indefinitely with pending Section 74A adjudication?
Can a blocked ECL prevent statutory pre-deposit for appeal?
What happens if the underlying SCN is later quashed?
Is interest or compensation available where working capital was illegally blocked?
Can officers be personally accountable for blocking despite clear binding jurisdictional precedent?
The demise of negative blocking will therefore not end Rule 86A litigation.
It merely moves the battle from:
HOW MUCH CAN BE BLOCKED?
to:
WHEN CAN EVEN THE AVAILABLE CREDIT BE BLOCKED?
THE CENTRAL FORMULA
The legal architecture after these decisions can be expressed simply.
WHERE ITC EXISTS TODAY
AVAILABLE ITC
RECORDED REASONS TO BELIEVE
RULE 86A GROUND
↓
TEMPORARY BLOCK POSSIBLE
subject to the statutory limits.
WHERE ITC HAS ALREADY BEEN USED
PAST ALLEGEDLY WRONGFUL ITC
↓
Instead:
INVESTIGATION
↓
SCN
↓
ADJUDICATION
↓
DETERMINED LIABILITY
↓
STATUTORY RECOVERY
That is the dividing line.
CONCLUSION: YOU CANNOT FREEZE TOMORROW'S CREDIT TO RECOVER YESTERDAY'S DISPUTE WITHOUT CLEAR STATUTORY AUTHORITY
Rule 86A is unquestionably a powerful anti-fraud mechanism.
It exists for a legitimate reason.
Fraudulent ITC can disappear rapidly through supply chains, and Government requires an emergency mechanism to protect credit that remains available while investigation proceeds.
But strength of purpose does not enlarge the text.
The phrase:
“credit of input tax available in the electronic credit ledger”
cannot casually be converted into:
“credit previously availed, already used, presently available, or which may become available in future.”
The latter would be a much broader Rule.
The rule-maker did not write it.
The Gujarat High Court recognised this in Samay Alloys.
The Delhi High Court built the full statutory architecture in Best Crop Science.
The Telangana, Punjab & Haryana and Bombay High Courts strengthened the same line.
Revenue's challenges to several Delhi decisions failed before the Supreme Court.
And on 18 June 2026, Revenue's challenge arising from K.K. Alloys met the same result—the Supreme Court declined interference while preserving ordinary lawful recovery remedies.
That last qualification says almost everything:
IF MONEY HAS TO BE RECOVERED, USE THE RECOVERY PROVISIONS.
Because:
BLOCKING IS NOT RECOVERY.
SUSPICION IS NOT ADJUDICATION.
FUTURE GENUINE ITC IS NOT AUTOMATICALLY TAINTED BY A PAST DISPUTE.
And perhaps most importantly:
RULE 86A CAN FREEZE CREDIT THAT EXISTS. IT CANNOT FIRST INVENT CREDIT THAT DOES NOT EXIST AND THEN CLAIM TO HAVE FROZEN IT.
The wider principle has significance far beyond the Electronic Credit Ledger:
AN EXTRAORDINARY PROTECTIVE POWER MUST REMAIN PROTECTIVE. THE MOMENT IT BEGINS ACHIEVING FINAL RECOVERY BEFORE DETERMINATION, THE STATUTORY BOUNDARY HAS BEEN CROSSED.
That is the real jurisprudential legacy of the Rule 86A negative-blocking controversy.

Disclaimer
This article is intended for professional, academic and legal discussion. The Supreme Court orders dismissing Revenue's SLPs should be understood in light of Kunhayammed: a non-speaking Article 136 dismissal does not by itself amount to a declaration of law under Article 141. The detailed legal ratios on negative blocking presently arise principally from the respective High Court judgments, and jurisdiction-specific precedent should be examined in each case.
