Adjudication is the Kerala Stamp Act's machinery for settling, in advance and authoritatively, the one question on which the validity of every chargeable instrument turns: how much duty is payable. Where the proper duty is doubtful, a party may bring the instrument to the Collector under Section 31, obtain his opinion, and on payment receive a certificate under Section 32 that conclusively stamps the document as duly stamped. This note maps Sections 31 to 32B - the application, the fee, the abstract and affidavit, the conclusive certificate, the undervaluation reference and the time-bars - and the Supreme Court and High Court authority that defines the Collector's powers and their limits.
What adjudication is - and why it exists
Adjudication, in stamp law, is the process by which a competent authority - the Collector - authoritatively determines the duty with which an instrument is chargeable. It is a planning device. The charging provision, Section 3, fixes liability the moment a listed instrument is executed in Kerala, as explained in liability of instruments to stamp duty; but liability is one thing and the precise quantum another. Where a document might fall under conveyance, mortgage, settlement or agreement, or where its market value is uncertain, the parties face a genuine risk of under-stamping and the consequent inadmissibility under Section 34. Sections 31 and 32 of the Kerala Stamp Act, 1959 allow that risk to be eliminated before the instrument is ever tendered in evidence or registered.
The scheme mirrors Sections 31 and 32 of the Indian Stamp Act, 1899, and the two are construed in pari materia, so that central authority on adjudication applies in Kerala. The object is twofold: to secure the revenue by ensuring correct payment, and to give the citizen certainty - a conclusive ruling that, once acted upon, protects the instrument from later challenge on the ground of insufficient stamping. See the Kerala Stamp Act hub for how adjudication fits the broader scheme.
Section 31: adjudication as to proper stamps
Section 31 is the gateway. When any instrument, whether executed or not and whether previously stamped or not, is brought to the Collector and the prescribed fee (a small fee within the statutory range) is paid, the Collector shall determine the duty, if any, with which, in his judgment, the instrument is chargeable. The provision is significant in three respects. First, an unexecuted draft can be adjudicated - a party may settle the duty on a deed before signing it, which is the classic planning use. Second, the applicant must, if the Collector so requires, furnish an abstract of the instrument and an affidavit or other evidence proving that all the facts and circumstances affecting the chargeability of the instrument, and the value of the property, have been truly set forth. Third, a protective proviso shields the applicant: no evidence so furnished shall be used against any person in any civil proceeding, except in an enquiry as to the duty with which the instrument is chargeable.
The requirement to disclose facts affecting chargeability dovetails with Section 28, which obliges the parties to set forth fully and truly the consideration and all facts bearing on duty. Adjudication is thus a candid, fact-based determination, not a rubber stamp; the Collector forms a judgment on the true legal character of the writing, applying the substance-over-nomenclature rule discussed in definitions of instrument, conveyance and settlement.
Section 32: the Collector's certificate and its conclusiveness
Section 32 supplies the outcome of adjudication. If the Collector is of opinion that the instrument is chargeable with duty and the full duty so determined has been paid, he shall certify by endorsement on the instrument that the full duty (stating its amount) has been paid; if he is of opinion that it is not chargeable, he shall certify that it is not so chargeable. The legal effect is decisive: an instrument so endorsed shall be deemed to be duly stamped or not chargeable, as the case may be, and, if chargeable, is receivable in evidence and may be acted upon and registered as if it had been originally duly stamped. The certificate is, in substance, conclusive proof that the instrument bears the proper duty.
That conclusiveness is hedged by a proviso. The certificate does not extend to (a) any instrument executed or first executed in Kerala and brought to the Collector after the expiration of one month from the date of its execution or first execution, and (b) instruments chargeable as bills of exchange or promissory notes when brought after execution. The one-month bar prevents the adjudication machinery from being used to launder a long-overdue instrument into validity; beyond the window, the document must be routed through the impounding and penalty machinery instead. The conclusive certificate is therefore available to the diligent, not the dilatory.
Opinion only: the Collector becomes functus officio
The leading authority on the reach of the Collector's adjudication power is Government of Uttar Pradesh v. Raja Mohammad Amir Ahmad Khan, AIR 1961 SC 787. There the executant brought an instrument to the Collector merely to obtain his opinion under Section 31 as to the duty chargeable. The Collector, after a reference to the Board of Revenue, determined the duty and then proceeded to impound the instrument and order payment of duty and penalty. The Supreme Court held this to be without jurisdiction. When an instrument is brought to the Collector only for his opinion under Section 31, his function is confined to determining and certifying the duty; he does not thereby acquire the power to impound under Section 33, which is triggered only when an instrument is produced before a person in the performance of his functions.
The Court held that once the Collector has given his opinion on the duty payable, he becomes functus officio on the impounding question - the power to impound and to levy penalty does not flow from the opinion-giving exercise. The two functions are distinct: adjudication on a voluntary reference is one thing; the coercive impounding of an instrument that comes before an authority in the discharge of its duties is another. This boundary remains the cornerstone of the law on adjudication, marking off the consensual Section 31 route from the compulsory Section 33 route examined in liability of instruments to stamp duty.
Section 32A: undervalued instruments and the reference to the Collector
Adjudication of duty on instruments of conveyance, exchange, gift, partition or settlement turns on value, and undervaluation is the commonest mode of evasion. Section 32A addresses it. Where the registering officer, while registering such an instrument, has reason to believe that the market value of the property or the consideration has not been truly set forth, he must, after registering the instrument, refer the matter to the Collector for determination of the market value and the proper duty. The Collector then, after notice to the parties and a hearing, provisionally and finally determines the market value and the duty chargeable, and the deficit duty is recovered.
The Collector's valuation must be a reasoned exercise. Under the framework of the Act and the Kerala Stamp (Prevention of Under-Valuation of Instruments) Rules, 1968, he is to have regard to relevant factors - the value of adjacent lands, the average yield, nearness to road and market, the level and nature of the land, and transport facilities - and to indicate the basis of his order. Section 32A is therefore a specialised valuation-adjudication that supplements the general Section 31 power; it operates on registered instruments where suspicion of undervaluation arises, whereas Section 31 operates on a voluntary reference by a party. The substance-over-form principle applies here too, since an instrument cannot escape duty by depressing the stated consideration below the true market value.
When adjudication is not required: Anitha Rajan
Adjudication is a facility, not an invariable obligation. The Kerala High Court made the point in Anitha Rajan v. Revenue Divisional Officer, AIR 2010 Ker 153, concerning a power of attorney executed outside India and engrossed on Indian non-judicial stamp paper of the proper value. The Court held that where the instrument already bears the proper stamp duty, it need not be produced before the Collector for adjudication under Section 31, nor does the timing machinery for foreign instruments under Section 18 (instruments other than bills and notes executed out of India, which must be stamped within three months of receipt in India) compel adjudication. The three-month requirement bites only on instruments not already properly stamped.
The decision usefully separates two ideas often conflated: the liability to duty, which exists by force of Section 3 and the charging scheme, and the process of adjudication, which is invoked only when the quantum is in doubt or a conclusive certificate is desired. A correctly stamped instrument is duly stamped whether or not a Collector has certified it; adjudication merely furnishes conclusive proof of that fact. The interplay with the timing of foreign instruments is developed in time of stamping.
Adjudication distinguished from impounding
The single most examined distinction in this area is between adjudication (Sections 31-32) and impounding (Sections 33 onwards). Adjudication is voluntary, anterior and consensual: a party chooses to bring the instrument for an opinion, typically before execution or before tendering it anywhere, and the Collector's role is to determine and certify duty. Impounding is compulsory, posterior and coercive: when an instrument not duly stamped is produced before a court, registering officer or public officer in the performance of his functions, that authority is bound to impound it under Section 33 and the instrument cannot be admitted in evidence under Section 34 until duty and penalty are paid.
The two routes carry different consequences. Under Section 31-32 no penalty is exacted - the applicant pays only the proper duty and the small adjudication fee. Under the impounding route, a penalty (historically up to ten times the deficient duty) is leviable in addition to the duty. Raja Mohammad Amir Ahmad Khan polices the boundary by holding that the Collector cannot convert a Section 31 opinion into a Section 33 impounding. The practical lesson is to adjudicate early and voluntarily, before the document is caught by the impounding machinery, where the cost is duty alone and not duty plus penalty.
Who adjudicates: the judicial function cannot be delegated
When an instrument is produced before a court, the question of determining its nature and the duty payable arises in the impounding context, and the Supreme Court has held that this determination is a judicial function that cannot be delegated. In Black Pearl Hotels (Pvt) Ltd. v. Planet M Retail Ltd., (2017) 4 SCC 498, the Court, construing the impounding scheme, held that although a judge may delegate to a court officer the ministerial task of examining and impounding an instrument and preparing a report, the determination of the nature and character of the instrument and the stamp duty chargeable must be performed by the court itself. The valuation and classification exercise is adjudicatory, not clerical.
The principle reinforces the character of adjudication as a reasoned application of the law to the instrument's true legal effect. Whether performed by the Collector under Section 31 or by a court determining duty in the course of impounding, the assessment of the proper duty is a quasi-judicial act requiring a hearing, the application of the charging Articles in the Schedule, and a speaking determination - it cannot be reduced to a mechanical endorsement by a subordinate.
Fiscal purpose: a curable defect, not a nullity
Adjudication exists to serve the Act's fiscal purpose, and the courts have consistently refused to let stamp objections become a weapon of technicality. In Hindustan Steel Ltd. v. Dilip Construction Co., (1969) 1 SCC 597 : AIR 1969 SC 1238, the Supreme Court held that the Stamp Act is a fiscal measure enacted to secure revenue for the State on certain classes of instruments, and is not enacted to arm a litigant with a weapon of technicality to defeat his opponent. Once the duty and any penalty are paid, the instrument becomes admissible and may be acted upon as if it had always been duly stamped.
That conciliatory approach was authoritatively reaffirmed by the seven-Judge Bench in In Re: Interplay between Arbitration Agreements under the Arbitration and Conciliation Act, 1996 and the Indian Stamp Act, 1899, decided on 13 December 2023, which held that non-stamping or insufficient stamping is a curable defect that renders an instrument inadmissible but not void or unenforceable, overruling the contrary view in N.N. Global Mercantile. Adjudication is the orderly mechanism by which the curable defect is cured in advance - the duty is determined and paid, the certificate is endorsed, and the document is rendered both valid and admissible at the outset.
Refund, remission and correction after adjudication
The Act provides relief where duty or penalty has been overpaid or wrongly charged in the course of the stamping machinery. Under Section 45, where a penalty has been paid under Section 34 or Section 39, the Government or the specified authority may, on a written application made within one year from the date of payment, refund the penalty wholly or in part; and where stamp duty in excess of that legally chargeable has been charged and paid, the excess may be refunded on application within three months of the order charging it. These provisions temper the rigour of over-assessment and reinforce that the object is correct duty, not maximum exaction.
Adjudication thus sits within a calibrated system: Section 31 to determine duty, Section 32 to certify it conclusively, Section 32A to police undervaluation on registration, the impounding machinery to catch the unstamped instrument that escapes voluntary adjudication, and the refund provisions to correct over-payment. A defect of mode - the right duty applied the wrong way - is a separate question, addressed in mode of stamping, but the adjudication of quantum is the foundation on which all of these later steps build.
Practical and examination takeaways
For the practitioner, the lessons are concrete. Adjudicate doubtful instruments under Section 31 before execution or before tendering them anywhere, because at that stage only duty and the small fee are payable and no penalty arises. Bring an executed Kerala instrument to the Collector within one month of execution if the conclusive certificate under Section 32 is wanted, because the proviso withdraws conclusiveness beyond that window. Set out all facts affecting chargeability fully and truly, both because Section 28 requires it and because Section 31 entitles the Collector to demand an abstract and affidavit. Where value is in issue on a conveyance or gift, anticipate the Section 32A reference and document the market value.
For the examinee, fix these propositions: Section 31 is voluntary adjudication on a reference, Section 32 yields a conclusive certificate subject to the one-month proviso, and Section 32A is the undervaluation reference on registration. The Collector who gives only an opinion under Section 31 cannot impound and becomes functus officio (Raja Mohammad Amir Ahmad Khan); the determination of an instrument's nature and duty is a non-delegable judicial function (Black Pearl Hotels); a properly stamped instrument needs no adjudication (Anitha Rajan); and insufficient stamping is a curable fiscal disability, not a nullity (Hindustan Steel; In Re Interplay). Master these and the adjudication chapter coheres with the charging and impounding schemes around it.
Frequently asked questions
What is adjudication of stamp duty under the Kerala Stamp Act, 1959?
Adjudication is the process under Section 31 by which a person brings an instrument - executed or unexecuted - to the Collector, pays the prescribed fee, and obtains the Collector's authoritative determination of the duty chargeable. On payment of the duty so determined, the Collector certifies the instrument under Section 32, after which it is deemed to be duly stamped and is receivable in evidence and capable of registration.
Is the Collector's certificate under Section 32 conclusive?
Largely, yes. An instrument endorsed under Section 32 is deemed to be duly stamped (or not chargeable) and may be acted upon and registered as if originally duly stamped. But the proviso withholds this conclusive effect from an instrument executed or first executed in Kerala and brought to the Collector after one month from its execution, and from instruments chargeable as bills of exchange or promissory notes brought after execution.
Can the Collector impound an instrument brought only for his opinion under Section 31?
No. In Government of Uttar Pradesh v. Raja Mohammad Amir Ahmad Khan, AIR 1961 SC 787, the Supreme Court held that when an instrument is brought to the Collector merely for his opinion under Section 31, he can only determine and certify the duty; he cannot impound it under Section 33 and becomes functus officio once the opinion is given. Impounding power arises only when an instrument is produced before an authority in the performance of its functions.
What is the difference between adjudication and impounding?
Adjudication under Sections 31-32 is voluntary and anterior - a party chooses to obtain a determination of duty, and only duty plus a small fee is payable. Impounding under Sections 33-34 is compulsory and coercive - an authority before whom an unstamped instrument is produced must impound it, and duty plus penalty must be paid before it is admissible. Adjudicating early avoids the penalty that the impounding route attracts.
How is undervaluation of an instrument dealt with?
Under Section 32A, where the registering officer believes that the market value or consideration in a conveyance, gift, exchange, partition or settlement has not been truly set forth, he refers the matter, after registration, to the Collector. The Collector, after notice and hearing and having regard to factors such as the value of adjacent lands, yield, and access to road and market, determines the true market value and recovers the deficit duty.
Does an instrument already properly stamped need adjudication?
No. In Anitha Rajan v. Revenue Divisional Officer, AIR 2010 Ker 153, the Kerala High Court held that a power of attorney executed abroad but engrossed on Indian stamp paper of the proper value need not be produced for adjudication under Section 31, nor does Section 18's three-month rule for foreign instruments compel it. Adjudication is required only where the quantum of duty is doubtful or a conclusive certificate is desired.
