Impounding of Documents (Sections 33, 38) →

Impounding is the operational heart of the Indian Stamp Act, 1899. The Act levies duty, but it is the impounding machinery of Chapter IV — anchored in Section 33 (the duty to examine and impound) and Section 38 (how an impounded instrument is dealt with) — that turns a paper obligation into collected revenue. The scheme is deceptively simple: any authority before whom a chargeable but inadequately stamped instrument surfaces must seize it; the document is then either regularised on payment of duty and penalty or sent in original to the Collector. Read together with the evidentiary bar in Section 35 and the finality rule in Section 36, these provisions decide whether a sale agreement, a hundi, a mortgage, or even an arbitration clause can be looked at by a court at all. This article maps the impounding process end to end — who must impound, when discretion creeps in, what penalty bites, how the Collector closes the loop, and how the Supreme Court from Hindustan Steel to In Re Interplay has kept the fiscal purpose of the Act from being weaponised as a litigation technicality.

The Chapter IV scheme: where impounding sits

The Indian Stamp Act, 1899 is, at bottom, a fiscal statute. Its charging provision (Section 3) imposes duty on the instruments listed in Schedule I, and the rest of the Act exists to make sure that duty is actually paid. Chapter IV — titled “Instruments not duly stamped” and running from Sections 33 to 48 — is the enforcement chapter. Within it, impounding is the pivot. Section 33 commands seizure of a chargeable instrument that is not duly stamped; Section 35 makes such an instrument inadmissible until duty and penalty are paid; Section 38 routes the impounded document and the money to the Collector; and Sections 39 to 42 give the Collector power to certify, refund and endorse. To understand impounding you must read these provisions as a single mechanism, not as isolated sections.

The phrase “not duly stamped” is the trigger for the whole chapter. Under the definition in Section 2(11), an instrument is “duly stamped” only when it bears a stamp of the proper amount and that stamp has been affixed or used in the manner prescribed by law. A document can therefore be “not duly stamped” either because it is wholly unstamped, because the duty is deficient, or because a stamp of the wrong description has been used — a distinction that the Supreme Court treated as decisive in Hariom Agrawal. For the foundational vocabulary, see our note on the key definitions and the overview in the introduction to the Stamp Act.

First principle: a fiscal measure, not a weapon of technicality

No account of impounding can begin anywhere except with Hindustan Steel Ltd. v. Dilip Construction Co., AIR 1969 SC 1238 : (1969) 1 SCC 597. There, an arbitration award was insufficiently stamped, and the question was whether the defect destroyed the claimant’s rights. Justice J.C. Shah, speaking for the Court, laid down the proposition that governs every impounding dispute to this day: “The Stamp Act is a fiscal measure enacted to secure revenue for the State on certain classes of instruments: it is not enacted to arm a litigant with a weapon of technicality to meet the case of his opponent. The stringent provisions of the Act are conceived in the interest of the revenue. Once that object is secured according to law, the party staking his claim on the instrument will not be defeated on the ground of the initial defect in the instrument.”

This single passage explains why impounding is curative rather than destructive. An instrument that is not duly stamped is not a nullity; it is a document that has not yet paid its tax. Once the duty and penalty are collected, the instrument is admitted and acted upon as if it had been properly stamped in the first place. Hindustan Steel thus draws the line between the Stamp Act and a penal forfeiture statute: the State wants its revenue, not the litigant’s defeat. Every later authority — Avinash Kumar Chauhan, P. Laxmi Devi, and ultimately the seven-judge bench in In Re Interplay — is a gloss on this first principle.

Section 33: the duty to examine and impound

Section 33(1) provides that “every person having by law or consent of parties authority to receive evidence, and every person in charge of a public office, except an officer of police, before whom any instrument, chargeable, in his opinion, with duty, is produced or comes in the performance of his functions, shall, if it appears to him that such instrument is not duly stamped, impound the same.” Section 33(2) directs that for that purpose every such person shall examine every instrument so produced in order to ascertain whether it is stamped with a stamp of the value and description required by the law in force when it was executed.

Three features of the text deserve emphasis. First, the obligation is cast in the imperative — “shall … impound” — so that once the conditions are met the authority has no choice. Second, the trigger is the authority’s opinion that the instrument is chargeable; the section operates on the officer’s prima facie view, not on a final adjudication of liability. Third, the duty attaches the moment the instrument is “produced or comes in the performance of his functions” — it is not confined to documents tendered in evidence, but extends to any instrument that crosses the desk of a public officer in the course of his duties. The deliberate exclusion of “an officer of police” means that a police officer who comes across an unstamped instrument during investigation is not obliged (indeed not empowered) to impound it under this section.

Who is bound to impound — and who is not

The class of persons bound by Section 33 is defined functionally, not by office. It captures two categories: (a) “every person having by law or consent of parties authority to receive evidence” — which squarely includes civil courts, criminal courts (subject to the proviso discussed below), and arbitrators or other tribunals authorised to take evidence; and (b) “every person in charge of a public office” — such as Registrars under the Registration Act, revenue officers, and other public functionaries. The only express carve-out within the second limb is the police officer.

That an arbitrator falls within the first limb has real consequences. In SMS Tea Estates (P) Ltd. v. Chandmari Tea Co. (P) Ltd., (2011) 14 SCC 66, the Supreme Court held that where an arbitration clause is contained in an instrument that is not duly stamped, the court dealing with a Section 11 application under the Arbitration and Conciliation Act, 1996 is itself a “person having authority to receive evidence” and is therefore bound to impound the instrument before acting on the arbitration clause. While the broader holding of SMS Tea Estates on enforceability was later revisited, its recognition that the impounding duty travels with the adjudicatory function remains good law and was expressly preserved in In Re Interplay. The duty, in short, follows the document, not the forum.

The criminal court proviso and the limits of compulsion

Section 33 is not uniformly mandatory across every forum. The proviso to Section 33 relaxes the imperative for criminal courts: nothing in the section requires a Magistrate or Judge of a Criminal Court to examine or impound, if he does not think fit to do so, any instrument coming before him in the course of any proceeding other than a proceeding under Chapter XII or Chapter XXXVI of the Code of Criminal Procedure, 1898 (now corresponding to the cognate chapters of the 1973 Code dealing with information to the police and maintenance of public order, and with the maintenance of wives, children and parents).

The rationale is practical. A criminal court is concerned with guilt and innocence, not with revenue collection, and forcing it to halt every trial to audit the stamp on a passing document would be absurd. The proviso therefore confers a discretion (“if he does not think fit”) on criminal courts in ordinary proceedings, while preserving the mandatory duty in the two specified classes of proceedings where the instrument is itself central. Outside the criminal sphere, however, the “shall” in Section 33(1) leaves no room for discretion: a civil court or public officer who forms the opinion that an instrument is chargeable and not duly stamped is bound to impound it.

Section 35: the evidentiary bar that gives impounding its teeth

Impounding would be toothless without Section 35, which makes an instrument chargeable with duty inadmissible in evidence unless it is duly stamped. The main clause provides that no such instrument “shall be admitted in evidence for any purpose by any person having by law or consent of parties authority to receive evidence, or shall be acted upon, registered or authenticated by any such person or by any public officer, unless such instrument is duly stamped.” The bar is absolute on its face — the instrument cannot be admitted “for any purpose,” which the courts have read to exclude even collateral use of an unstamped chargeable instrument.

But Section 35 is also the cure. Proviso (a) permits an instrument that is not duly stamped (other than certain instruments such as bills of exchange and promissory notes, which proviso (b) excludes from regularisation) to be admitted in evidence on payment of the deficient duty together with a penalty — calculated as a sum equal to ten times the amount of the proper duty or the deficient portion, subject to the statutory floor. Once that payment is made, the bar lifts. The two conditions that must coexist for the bar to operate are settled: the instrument must be (i) chargeable with duty, and (ii) not duly stamped. If either is absent, Section 35 has no application — a point the Supreme Court underscored in Vijay v. Union of India, 2023 INSC 1030, holding that an instrument not chargeable with duty at the date of execution falls outside the bar entirely. For when chargeability arises, see our note on liability of instruments to duty.

The penalty under proviso (a): ten times, and the discretion to mitigate

The penalty fixed by proviso (a) to Section 35 — a sum equal to ten times the deficient duty — looks draconian, and it is meant to. The intent is to make non-stamping a poor economic bet. Yet the courts have read the figure as a ceiling rather than a rigid tariff when the matter goes to the Collector. In Hindustan Steel, the Court observed that the maximum penalty is ten times the deficiency, but that the authority may, in an appropriate case, levy a smaller penalty depending on the circumstances, because the object is to secure revenue and discourage evasion, not to confiscate.

A crucial structural point follows. Where the instrument is admitted by the court itself under proviso (a), the statute fixes the penalty at ten times the deficient duty — the court ordinarily has no power to reduce it, because the proviso is mandatory in its terms. The discretion to levy a lesser penalty is conferred on the Collector when the instrument is sent to him under Section 40 (and, where appropriate, Section 39, which allows the Collector to refund excess penalty). This is why parties anxious to minimise the penalty sometimes prefer to have the instrument impounded and forwarded to the Collector rather than regularised across the counter at ten times the deficiency. The distinction between the court’s mechanical application of the ten-times figure and the Collector’s mitigating discretion is one of the most practically important features of the impounding scheme.

No admission even for a collateral purpose: Avinash Kumar Chauhan

A recurring litigation tactic is to argue that even if an unstamped instrument cannot prove its primary transaction, it may still be looked at for some “collateral purpose” — to prove the nature of possession, an admission, or a related fact. The Stamp Act forecloses this. In Avinash Kumar Chauhan v. Vijay Krishna Mishra, (2009) 2 SCC 532, the Supreme Court held that an unstamped agreement to sell, being chargeable with duty but not duly stamped, could not be admitted in evidence “for any purpose,” including any collateral purpose, unless the deficient duty and penalty were first paid under proviso (a) to Section 35. The Court directed that the document be impounded and the requisite duty and penalty recovered before it could be looked at at all.

This is a sharper position than that under the Registration Act, 1908, where an unregistered document may be received for a collateral purpose under the proviso to Section 49. Under the Stamp Act there is no such relaxation: the words “for any purpose” in Section 35 are read literally, and the remedy is not exclusion but impounding followed by payment. Avinash Kumar Chauhan therefore confirms two things at once — the breadth of the Section 35 bar and the curative, revenue-collecting character of impounding that Hindustan Steel first articulated.

A copy is not an instrument: Hariom Agrawal

Impounding presupposes an instrument. Section 2(14) defines “instrument” to include every document by which any right or liability is created, transferred, limited, extended, extinguished or recorded. A photocopy creates nothing; it merely reproduces. In Hariom Agrawal v. Prakash Chand Malviya, (2007) 8 SCC 514 : AIR 2008 SC 166, a three-judge bench held that there is no scope for impounding a copy of a document under Sections 33 or 35, because those provisions operate only on the original instrument within the meaning of Section 2(14). “There is no scope for the inclusion of the copy of the document for the purposes of the Indian Stamp Act,” the Court held; the deficiency in stamping of the original cannot be cured by producing or impounding a photocopy.

The case also clarified a second point of lasting importance: a defect in stamping cannot be cured by amendment or by treating the document differently. Where an original instrument bears a stamp of insufficient amount or of the wrong description, the cure lies in impounding the original and paying duty and penalty — not in finessing the form. The practical lesson for litigators is unforgiving: if the original is lost and only a copy survives, the Stamp Act offers no impounding route to admissibility, and the party may be left without an admissible instrument at all. This dovetails with the rules on the time of stamping and the mode of stamping, which fix when and how the original had to be stamped in the first place.

Section 36: once admitted, the objection is gone

The mirror image of the impounding duty is the rule of finality in Section 36: “Where an instrument has been admitted in evidence, such admission shall not, except as provided in section 61, be called in question at any stage of the same suit or proceeding on the ground that the instrument has not been duly stamped.” The provision is a sharp procedural guillotine — the stamping objection must be taken at the moment the document is tendered, or it is lost for the rest of the suit.

The leading authority is Javer Chand v. Pukhraj Surana, AIR 1961 SC 1655. There, certain hundis were objected to as inadequately stamped, but they were marked as exhibits and used in examination and cross-examination. The Supreme Court held that once a document has been marked as an exhibit and the trial has proceeded on that footing, Section 36 comes into operation, and it is not open either to the trial court or to a court of appeal or revision to go behind that order. The Court added that an objection as to admissibility on the ground of stamping “has to be decided then and there when the document is tendered in evidence” — the parties cannot reserve the point for later. The only exception is the one Section 36 itself preserves: Section 61, under which the Court of appeal or revision can correct an erroneous admission at the instance of the revenue, but not at the instance of a litigant seeking to escape the document.

Section 38: how an impounded instrument is dealt with

Section 38 closes the loop by routing the impounded instrument to the Collector. It draws a two-way distinction. Under Section 38(1), where the person impounding the instrument has authority to receive evidence and admits the instrument in evidence on payment of penalty under Section 35 or of duty under Section 37, he must send to the Collector an authenticated copy of the instrument, together with a certificate in writing stating the amount of duty and penalty levied, and must remit that amount to the Collector (or to such person as the Collector may appoint). In this branch, the original stays on the court’s record and only a certified copy and the money go to the Collector — because the duty has already been collected and the instrument has already been admitted.

Under Section 38(2), “in every other case” — that is, where the instrument has been impounded but duty and penalty have not been paid into the court — the person impounding it must send the instrument in original to the Collector. The Collector then exercises his powers under Sections 39 and 40 to determine the duty and penalty, recover them, and certify the instrument. Section 38 thus performs a double function: it guarantees that the State learns of every impounded instrument, and it places the original before the only authority — the Collector — who has the discretion to mitigate the penalty below the statutory ten-times figure.

The Collector closes the file: Sections 39, 40 and 42

Once an instrument reaches the Collector under Section 38(2), three provisions govern its fate. Section 40 empowers the Collector, on examining an impounded instrument, to determine whether it is duly stamped; if it is not, he may require payment of the proper duty (or the deficient portion) together with a penalty of five rupees, or, if he thinks fit, a penalty not exceeding ten times the deficient duty. This is the locus of the mitigating discretion that Hindustan Steel recognised: the Collector, unlike the court applying proviso (a) to Section 35, may calibrate the penalty to the gravity of the default.

Section 39 supplements this by empowering the Collector, in cases referred to him under Section 38(1), to refund any portion of the penalty exceeding five rupees that has been paid, where he is of opinion that the penalty was excessive. Section 42 then completes the cycle: once the duty (and any penalty) has been paid, the Collector certifies by endorsement on the instrument that the proper duty (or duty and penalty) has been levied, and the instrument so endorsed is thereafter admissible in evidence and may be acted upon and registered as if it had been duly stamped. The endorsement under Section 42 is what converts a once-defective instrument into a fully valid one — the formal moment at which Hindustan Steel’s promise (“once that object is secured … the party … will not be defeated”) is redeemed.

Constitutional validity of the stringent machinery: P. Laxmi Devi

Because the impounding-and-penalty machinery can require a litigant to part with substantial sums before his document is even looked at, its constitutional validity has been challenged. In Government of A.P. v. P. Laxmi Devi, (2008) 4 SCC 720, the Supreme Court upheld the stringent provisions — including a State amendment requiring deposit of deficit duty (and, in the impugned form, a percentage of it) before a reference to the Collector — as constitutionally valid. Justice Markandey Katju, applying the doctrine of judicial restraint in economic legislation, held that fiscal statutes of this kind are entitled to a presumption of constitutionality and that the requirement to secure revenue before adjudication does not offend Article 14, being a reasonable measure to plug evasion and ensure speedy realisation of stamp duty.

The decision reinforces the Hindustan Steel philosophy from the constitutional side: the very stringency of impounding — mandatory seizure, a heavy penalty, inadmissibility until payment — is justified precisely because the Act is a revenue measure. The Court was careful to note that the provisions are not penal in the confiscatory sense; they exist to collect the tax, and the litigant who pays gets his instrument back, fully effective. P. Laxmi Devi thus situates impounding within the broader law of economic regulation, where courts defer to the legislature’s choice of revenue-protecting machinery.

Impounding meets arbitration: In Re Interplay

The most consequential recent development concerns the collision between the impounding duty and the policy of speedy arbitration. In N.N. Global Mercantile (P) Ltd. v. Indo Unique Flame Ltd. (No. 2), (2023) 7 SCC 1, a five-judge bench had held (3:2) that an unstamped arbitration agreement was void and unenforceable — reasoning that since the instrument could not be acted upon under Section 35 until stamped, the arbitration clause embedded in it was a non-starter. That position threatened to convert the impounding bar into a substantive defence to arbitration.

The matter was referred to a larger bench, and in In Re: Interplay Between Arbitration Agreements under the Arbitration and Conciliation Act, 1996 and the Indian Stamp Act, 1899, 2023 INSC 1066 : (2024) 6 SCC 1, a seven-judge bench unanimously overruled N.N. Global (No. 2). The Court held that non-stamping or insufficient stamping is a curable defect that renders an instrument inadmissible in evidence under Section 35, but does not render it void or unenforceable. Crucially for our subject, the Court reaffirmed that the impounding obligation under Section 33 survives — the appropriate forum (the arbitral tribunal, rather than the referral court at the Section 11 stage) must impound the instrument and ensure duty and penalty are paid — but that this is a question of admissibility to be cured, not of validity. The decision is a modern restatement of Hindustan Steel: impounding secures the revenue without defeating the substantive bargain. For how chargeability and adjudication interlock with this scheme, see our note on the determination and adjudication of stamp duty and the Indian Stamp Act hub.

Exam takeaways and common traps

For the judiciary and CLAT-PG aspirant, a handful of crisp propositions carry most of the marks. One: Section 33 is mandatory (“shall impound”) for civil courts and public officers, but discretionary for criminal courts under the proviso (except in the specified CrPC chapters), and a police officer is expressly excluded. Two: the trigger is the authority’s prima facie opinion that the instrument is chargeable and not duly stamped; impounding does not await a final adjudication. Three: Section 35 bars admission “for any purpose,” including collateral purposes (Avinash Kumar Chauhan), and the cure is payment of duty plus a penalty of ten times the deficiency under proviso (a).

Four: the court applying proviso (a) generally levies the full ten-times penalty; only the Collector (under Sections 39 and 40) may mitigate it (Hindustan Steel). Five: Section 36 makes admission final — the stamping objection must be taken when the document is tendered, and once it is marked as an exhibit it cannot be reopened (Javer Chand), save under Section 61. Six: a copy is not an instrument and cannot be impounded (Hariom Agrawal). Seven: non-stamping is curable and does not void the instrument; an arbitration clause in an unstamped contract remains enforceable, subject to impounding (In Re Interplay, overruling N.N. Global (No. 2)). The single thread tying all seven together is Hindustan Steel’s axiom: the Stamp Act is a fiscal measure, not a weapon of technicality.

Frequently asked questions

Is impounding under Section 33 mandatory or discretionary?

It is mandatory for every person authorised to receive evidence and every person in charge of a public office (the section uses “shall … impound”), once they form the opinion that the instrument is chargeable and not duly stamped. The only relaxation is the proviso to Section 33, which gives a criminal court a discretion (“if he does not think fit”) except in proceedings under the specified chapters of the CrPC. A police officer is expressly excluded from the impounding duty.

Can an unstamped document be used for a collateral purpose?

No. Unlike the Registration Act, the Stamp Act bars admission “for any purpose.” In Avinash Kumar Chauhan v. Vijay Krishna Mishra (2009) the Supreme Court held that a chargeable but unstamped instrument cannot be admitted even for a collateral purpose unless the deficient duty and penalty are first paid under proviso (a) to Section 35; the document must be impounded and regularised before it can be looked at at all.

What is the difference between Section 38(1) and Section 38(2)?

Under Section 38(1), where the impounding authority can receive evidence and has admitted the instrument on payment of penalty (Section 35) or duty (Section 37), it keeps the original on its record and sends the Collector only an authenticated copy, a certificate of the duty and penalty levied, and the money. Under Section 38(2), “in every other case” — where duty and penalty have not been paid — the original instrument itself is sent to the Collector for action under Sections 39, 40 and 42.

Can the court reduce the ten-times penalty under Section 35?

Generally no. When a court admits an instrument under proviso (a) to Section 35, the statute fixes the penalty at ten times the deficient duty and the court has no power to scale it down. The discretion to levy a lesser penalty rests with the Collector under Sections 39 and 40, as recognised in Hindustan Steel Ltd. v. Dilip Construction Co. (1969), where the ten-times figure was read as a ceiling that the Collector may mitigate in an appropriate case.

Can a photocopy of an unstamped document be impounded?

No. In Hariom Agrawal v. Prakash Chand Malviya (2007) the Supreme Court held that Sections 33 and 35 operate only on an “instrument” within the meaning of Section 2(14), which a copy is not. There is no scope for impounding a copy, and the deficiency in stamping of the original cannot be cured by producing a photocopy. If the original is lost, the Stamp Act offers no impounding route to admissibility.

Does non-stamping make an arbitration agreement void?

No, not any longer. In In Re Interplay (2023, seven-judge bench) the Supreme Court overruled N.N. Global (No. 2) and held that non-stamping or insufficient stamping is a curable defect that makes an instrument inadmissible under Section 35 but does not render it void or unenforceable. The arbitration clause remains enforceable; the appropriate forum must impound the instrument under Section 33 and ensure duty and penalty are paid.
