A criminal judgment is not written on documents and depositions alone. Lying on the evidence table — sealed, tagged and numbered — are the material objects: the weapon of assault, the blood-stained clothing, the recovered ornaments, the contraband. These are the things the eye can see and the hand can hold, and a well-written judgment must account for each of them: how it was seized, how it travelled to court, whether a witness identified it, what the expert said about it, and finally what the court makes of it. This chapter explains how material exhibits are marked, proved, appraised and disposed of, and how a judge weaves them into the reasoning so that the silent objects on the table are made to testify.
What a material exhibit is — and how it differs from a documentary exhibit
In the architecture of a criminal trial, the evidence that reaches the record falls into three broad streams: oral testimony of witnesses, documents, and material objects. A material object — universally abbreviated MO in Indian courts — is any tangible, physical thing produced before the court otherwise than as a document: a knife, a country-made pistol, a blood-stained shirt, a torn salwar, a quantity of seized ganja, a set of gold ornaments, a broken bottle, a forged seal. Documents are read; material objects are seen and examined. That distinction governs how each is marked, how each is proved, and how each is described in the judgment.
The functional difference matters for the judgment writer. A document speaks through its contents and is exhibited under the Bharatiya Sakshya Adhiniyam, 2023 (formerly the Evidence Act); a material object speaks through its physical existence and its connection to the crime. A shirt does not say who wore it — the court must connect it to the accused through the seizure witness, the identifying witness, the serologist and the chain of custody. This is why a careless judgment that simply records "MO-1 the knife was produced" without tracing that connecting thread is incomplete. For the place of exhibits within the overall scheme, see our chapter on the structure of a criminal judgment and the foundational introduction, importance and statutory basis.
Marking and numbering: the MO convention
When a material object is produced and the court admits it for the purpose of the trial, it is marked with an exhibit identifier. The settled convention across Indian trial courts is to mark material objects in a separate, continuous series prefixed MO — MO-1, MO-2, MO-3 — kept distinct from the prosecution documentary exhibits (typically Ext. P-1, P-2…), the defence exhibits (Ext. D-1, D-2…) and court exhibits (Ext. C-1…). The separate series prevents confusion: when the judgment later reasons that "the knife MO-3 answers the dimensions of the incised wound spoken to by PW-9, the doctor", the reader knows instantly that a physical object, not a document, is being discussed.
The act of marking is purely for identification and case-management; it is not, by itself, proof. A thing marked MO-1 has merely been brought on record and labelled — its connection to the offence and to the accused still has to be established through admissible evidence. The judgment must therefore never treat the bare marking as if it were proof of the object's relevance. A disciplined judge, when listing the material objects produced, records the MO number, a short description, by whom it was produced, and the witness through whom it was identified — so that the appraisal section can return to each item by its number. The numbering discipline mirrors the care taken with the cause title, court, case number and parties at the head of the judgment.
Seizure and chain of custody under the BNSS
The life of a material exhibit begins at seizure. Under the Bharatiya Nagarik Suraksha Sanhita, 2023, the investigating officer's power to seize property suspected to be connected with an offence is recognised, and Section 105 BNSS introduces a significant new safeguard: the process of conducting a search and seizure, including the preparation of the list of all things seized, is to be recorded through audio-video electronic means — preferably a mobile phone — and the recording forwarded to the jurisdictional Magistrate without delay. This electronic record now forms part of the foundation a judgment must examine when the seizure of a material object is disputed.
From seizure onward, the object must travel an unbroken chain of custody: seizure memo, sealing, deposit in the malkhana (property room) with malkhana register entries, forwarding to the Forensic Science Laboratory under proper memos, and production in court with the seals intact. A judgment that pronounces upon a recovered weapon or a sample of contraband must satisfy itself that the seals described by the seizing officer match the seals examined by the expert and the seals opened in court. Where the prosecution cannot account for the article between seizure and analysis, the evidentiary value of the material object is gravely weakened — a recurring theme where seizure witnesses turn hostile and only the investigating officer's word remains. The same insistence on a complete, accounted-for record animates the statement of the prosecution case, where the seizures are first narrated.
Production and proof of the object in court
It is not enough that an object was seized; it must be produced in court and connected to the case through a witness. The seizing officer proves the seizure; an identifying witness — often the complainant or an eyewitness — connects the object to the crime or to the accused; and where the object is a weapon, contraband or biological material, an expert connects it to the injury, the offence or the accused's person. A judgment that records a recovery but never notes that the object was actually exhibited and put to a witness leaves a gap that an appellate court will readily exploit.
This is also why material objects must be put to the accused. Under Section 351 of the BNSS (corresponding to Section 313 of the old Code), every incriminating circumstance appearing in the evidence — including a recovery of a material object at the instance of the accused — must be put to him so that he has an opportunity to explain it. If the recovery of MO-2 (the murder weapon) at the pointing out of the accused is treated as incriminating in the judgment but was never put to him under Section 351, that circumstance cannot be used against him. A meticulous judgment cross-checks each material object relied upon against the Section 351 examination — a discipline closely tied to recording the plea of the accused and the defence taken.
Identification: making the object speak to the accused
A recovered article is evidentially inert until a witness identifies it. Where stolen property or ornaments are recovered, the prosecution ordinarily holds a test identification parade of the articles and, more importantly, secures their identification in court. In Earabhadrappa alias Krishnappa v. State of Karnataka, AIR 1983 SC 446, the Supreme Court dealt with the recovery of ornaments belonging to the deceased at the instance of the accused who had been absconding. The Court held that a gap of about a year between the offence and the recovery was not too long, given that the accused had absconded and the articles were not of a kind that pass readily from hand to hand; coupled with the accused's false denial of the recovery, the unexplained possession attracted the presumption under Illustration (a) to Section 114 of the Evidence Act (now the Bharatiya Sakshya Adhiniyam, 2023). The case is the classic authority on how identified, recovered material objects, properly proved, can sustain a conviction.
The lesson for the judgment writer is that identification must be expressly recorded: who identified the article, by what distinguishing features, and whether the identification was tested. A bald statement that "the ornaments were recovered" is worthless unless the judgment also shows that they were identified as the property of the deceased or the complainant. Identification in court is substantive evidence; a prior test identification parade is corroborative.
Weapons, injuries and the expert connection
Few material objects are scrutinised as closely as the weapon of offence, and few mistakes are as fatal as relying on a weapon that has not been connected to the injuries. The locus classicus is Mohinder Singh v. The State, AIR 1953 SC 415, where the Supreme Court laid down that in a case of death caused by injuries from a lethal weapon, the prosecution must prove by expert evidence that it was likely, or at least possible, for the injuries to have been caused with the weapon with which, and in the manner in which, they are alleged to have been caused. On the facts, the ballistic evidence connecting the firearm to the fatal injuries was found wanting, and the conviction was set aside.
A judgment dealing with a weapon must therefore do more than note that MO-1, the knife, was recovered. It must record the doctor's opinion that the injuries could have been caused by such a weapon, and — where the weapon is a firearm — the ballistic expert's opinion connecting the recovered cartridges or projectiles to the recovered firearm. Where blood is found on the weapon or clothing, the serologist's report on the blood group, and now DNA, supplies the link between the object and the victim. The judgment must engage with each of these expert connections; an unexamined weapon proves nothing.
Effect of non-production or non-recovery of a material object
Aspirants frequently overstate the consequence of a missing material object. The settled position is that non-recovery of the weapon of assault is not, by itself, fatal to the prosecution where the ocular evidence is reliable and consistent with the medical evidence. The Supreme Court has repeatedly held that recovery of the weapon is not a sine qua non for conviction; what matters is the totality of the evidence. A judgment is therefore entitled to convict on cogent eyewitness testimony corroborated by medical evidence even though the weapon was never recovered.
The position changes where an object was seized but is then not produced before the court without explanation. Where seized material is withheld from the trial court as a material exhibit and no reason is offered for its non-production, an adverse view becomes available, especially where the prosecution case turns on that very object. The judgment must distinguish the two situations: a weapon that was never found, versus an article that was seized but suppressed. The former goes to sufficiency of other evidence; the latter raises a suspicion of fabrication that the court must squarely address in its reasoning.
Contraband, sampling and the integrity of the seized substance
In narcotics, excise and food-adulteration prosecutions the material exhibit is the seized substance itself, and the judgment lives or dies on the integrity of the sample. The court must trace the substance from seizure, through representative sampling and sealing at the spot, deposit in the malkhana, dispatch to the chemical examiner, and the examiner's report — all with seals shown to be intact at each stage. Any unexplained discrepancy in the weight, the number of seals, or the description between the seizure memo and the FSL report goes to the root of the case, because the prosecution must establish that the substance analysed is the very substance seized from the accused.
For the judgment writer this means the material-exhibit reasoning in a contraband case cannot be perfunctory. The judge should set out, item by item, the sample number, the seal impressions, the malkhana entries and the FSL findings, and then record a clear finding that the chain is — or is not — complete. Where it is broken, the benefit goes to the accused regardless of the apparent strength of the recovery, because the link between the accused and the contraband material object has not been established beyond reasonable doubt.
The prosecution's duty to disclose all material objects
Fairness of trial demands that the accused know not only the material objects relied upon but also those gathered and not relied upon. In Manoj v. State of Madhya Pradesh, 2022 LiveLaw (SC) 510, the Supreme Court directed that the prosecution in all criminal cases shall furnish to the accused a list of statements, documents, material objects and exhibits which are not relied upon by the investigating officer, observing that the role of the public prosecutor is to conduct a fair trial and not to secure conviction at any cost. This disclosure obligation flows from the accused's right to a fair trial and the principle that the State must not suppress material that might assist the defence.
A judgment writer should be alive to this duty when a grievance of non-disclosure is raised. If a material object that could have aided the defence was withheld, or its existence concealed, the court must consider the prejudice caused and may draw an adverse inference. Conversely, where the disclosure has been made and the defence chose not to summon the object, the judgment can note that the accused had the opportunity and did not avail of it. The disclosure principle therefore feeds directly into how the court appraises the completeness and fairness of the prosecution's presentation of material exhibits.
Custody and interim disposal during trial
Material objects must be preserved intact until the judgment, but many — perishables, vehicles, livestock, currency — cannot sensibly be kept in a malkhana for years. Section 497 of the BNSS (corresponding to Section 451 of the old Code) empowers the court to make such order as it thinks fit for the proper custody of property produced before it pending the inquiry or trial, and, if the property is subject to speedy and natural decay or it is otherwise expedient, to order its sale or disposal after recording evidence as may be necessary to identify it.
The leading guidance is Sunderbhai Ambalal Desai v. State of Gujarat, (2002) 10 SCC 283, where the Supreme Court deprecated the practice of letting seized articles — particularly vehicles — rot in police stations and laid down that courts should pass orders for interim custody promptly, after the article is photographed, its panchnama prepared and identifying particulars recorded, on appropriate security and an undertaking to produce it when required. The judgment in the main case is not affected by such interim custody, because the photographs, panchnama and identification details preserve the evidentiary value of the object even after it is released. A trial judge who applies Sunderbhai correctly avoids both the decay of property and any prejudice to the eventual appraisal of the material exhibit.
Final disposal of material exhibits in the judgment
Every criminal judgment must conclude with an express order on the disposal of the material objects. Section 498 of the BNSS (corresponding to Section 452 of the old Code) requires that when an inquiry or trial in a criminal court is concluded, the court may make such order as it thinks fit for the disposal — by destruction, confiscation, or delivery to any person claiming to be entitled to possession — of any property or document produced before it or in its custody, or regarding which any offence appears to have been committed or which has been used for the commission of any offence.
The operative part of the judgment should therefore deal with each material exhibit by its MO number: the weapon and contraband ordinarily ordered to be destroyed or confiscated; stolen ornaments and recovered property ordered to be returned to the rightful owner; case property of value ordered to abide the result of any appeal. A common error is to convict or acquit and then forget the material objects altogether, leaving the malkhana cluttered and the rightful owner without his property. A complete judgment ties up every object, and where an appeal is likely, defers actual destruction until the appeal period has expired so that the exhibit remains available to the appellate court.
How to record material exhibits in the body of the judgment
Bringing it together, a well-structured judgment handles material exhibits in three distinct places. First, in the narration of the prosecution evidence, the judgment lists the material objects produced — MO-1 to MO-n — with a one-line description and the witness through whom each was proved and identified. Secondly, in the appraisal of evidence, the judgment returns to the relevant objects by number and reasons about each: was the seizure proved, was the chain of custody intact, did a witness identify it, did the expert connect it, was it put to the accused under Section 351 BNSS? Thirdly, in the operative portion, the judgment orders the disposal of every object under Section 498 BNSS.
The cardinal rule is that the material-exhibit reasoning must be specific. Generic recitals — "the material objects support the prosecution" — are the hallmark of a weak judgment. The court must say why MO-3, the blood-stained shirt, supports the prosecution: because PW-2 identified it as the shirt the deceased wore, the seizure was proved by PW-11, the serologist found human blood of the deceased's group on it, and the seals were intact. For the larger framework into which this reasoning fits, see the structure of a criminal judgment and the broader criminal judgment writing hub.
Common errors to avoid with material exhibits
Several recurring errors appear in trial-court judgments and in examination answers. The first is treating the bare marking of an object as MO-1 as proof of its relevance — marking is identification, not proof. The second is relying on a recovered weapon or article without recording its identification by a witness or its connection to the injury through expert evidence, contrary to Mohinder Singh. The third is using a recovery at the instance of the accused as an incriminating circumstance without having put it to him under Section 351 BNSS. The fourth is overlooking a broken chain of custody in a contraband case while still convicting on the recovery.
The fifth and most avoidable error is the silent judgment — one that convicts or acquits but passes no order on the material objects under Section 498 BNSS, leaving property undisposed and owners uncompensated. A sixth error, the mirror image, is destroying or releasing case property before the appeal period has run, contrary to the caution counselled by Sunderbhai Ambalal Desai. Avoiding these errors is what separates a serviceable judgment from a sound one, and the material-exhibit portion is frequently where examiners and appellate courts test whether the judge has actually applied his mind to the evidence on the table.
Frequently asked questions
What is the difference between a material object (MO) and a documentary exhibit?
A documentary exhibit is proved by its contents and is read into the record (typically marked Ext. P-1, D-1, etc.), whereas a material object is a tangible physical thing — a weapon, clothing, ornaments, contraband — that is seen and examined, and is marked in a separate continuous series prefixed MO (MO-1, MO-2). A document speaks through what it says; a material object must be connected to the crime and the accused through the seizure witness, an identifying witness, the chain of custody and, where relevant, expert opinion.
Is recovery of the weapon essential for a murder conviction?
No. The Supreme Court has consistently held that recovery of the weapon of assault is not a sine qua non for conviction; non-recovery is not fatal where the ocular evidence is reliable and consistent with the medical evidence. However, if a weapon is relied upon, Mohinder Singh v. The State, AIR 1953 SC 415 requires the prosecution to prove by expert evidence that the injuries were likely, or at least possible, to have been caused by that weapon in the manner alleged.
Must a recovered material object be put to the accused?
Yes, if it is to be used against him. Under Section 351 of the BNSS, 2023 (formerly Section 313 CrPC), every incriminating circumstance appearing in the evidence — including the recovery of a material object at the instance of the accused — must be put to him so he can explain it. If a recovery is treated as incriminating in the judgment but was never put to the accused under Section 351, that circumstance cannot be used to convict him.
How are recovered articles identified, and why does it matter?
Recovered articles such as stolen ornaments are ordinarily identified through a test identification parade of articles and, more importantly, by identification in court, which is substantive evidence. In Earabhadrappa v. State of Karnataka, AIR 1983 SC 446, identified ornaments recovered at the instance of an absconding accused, coupled with his false denial, attracted the presumption under Illustration (a) to Section 114 of the Evidence Act. Identification matters because an unidentified recovered article proves nothing against the accused.
What must a judgment say about the disposal of material exhibits?
Every criminal judgment must pass an express order on the disposal of material objects under Section 498 of the BNSS (formerly Section 452 CrPC): weapons and contraband are ordinarily destroyed or confiscated; stolen property and ornaments are returned to the rightful owner; valuable case property is ordered to abide the result of any appeal. Failing to dispose of the objects, or destroying them before the appeal period expires, is a common and avoidable error — the latter cautioned against in Sunderbhai Ambalal Desai v. State of Gujarat, (2002) 10 SCC 283.
Does the prosecution have to disclose material objects it does not rely upon?
Yes. In Manoj v. State of Madhya Pradesh, 2022 LiveLaw (SC) 510, the Supreme Court directed that the prosecution in all criminal cases must furnish the accused a list of statements, documents, material objects and exhibits not relied upon by the investigating officer, emphasising that the prosecutor's role is to ensure a fair trial rather than to secure conviction at any cost. Where a material object that could aid the defence is suppressed, the court may consider the prejudice and draw an adverse inference.
