Non-production of seized materials before the court can be fatal to the prosecution case, especially if the materials are crucial evidence. For example, the High Court observed, The non-production of the seized material is therefore considered fatal to the prosecution case. ["Naresh Yadav VS State of Bihar - Patna"]
Delay in sending samples or electronic evidence (such as pendrives or CDs) to forensic laboratories without proper explanation can severely undermine the prosecution's case. Multiple judgments highlight that delays ranging from 8 to 18 days, if unexplained, cast doubt on the integrity of the evidence, making the case doubtful. For instance, The delay of 18 days, in sending the samples, to the office of the Forensic Science Laboratory, and non-strict proof, by the prosecution, that the same was not tampered with, till it was deposited in that office, must prove fatal to the case of the prosecution. ["Jagir Singh VS State of Haryana - Punjab and Haryana"]
The possibility of tampering with evidence during delays in transfer to forensic labs is a critical concern. The courts have emphasized that the possibility of tampering with the sample parcel could not be ruled out, and failure to explain such delays is often deemed fatal to the prosecution. ["Bahadur Singh S/o Nidhan Singh VS State of Haryana - Punjab and Haryana"]
Non-examination of independent witnesses and absence of proof that samples remained untampered until analysis further weaken the case. For example, No explanation, whatsoever, has been furnished, by the prosecution witnesses, with regard to this material discrepancy, occurring in the affidavit, Ex.PB, vis-a-vis, the report of the Forensic Science Laboratory. ["Kundan Singh VS State Of Haryana - Punjab and Haryana"]
In cases involving digital evidence such as pendrives or CDs, delays in sending the electronic device to forensic labs and damage to the evidence (like a damaged CD) can lead the courts to consider the evidence unreliable or inadmissible. For example, The delay of 14 days, in sending the sample to the office of the Forensic Science Laboratory, and non-strict proof, by the prosecution, that the same was not tampered with, till it was deposited in that office, must prove fatal to the case of the prosecution. ["Kundan Singh VS State Of Haryana - Punjab and Haryana"]
Overall, the courts have consistently held that unexplained delays, lack of proper proof of integrity, and non-production of crucial seized materials or electronic evidence are often fatal to the prosecution. The integrity and timely handling of evidence are essential for establishing a case beyond reasonable doubt. ["Naresh Yadav VS State of Bihar - Patna"] ["JAGIR SINGH AND ANR. vs STATE OF HARYANA - Punjab and Haryana"] ["JAGIR SINGH AND ANR. vs STATE OF HARYANA - Punjab and Haryana"]
Conclusion:The failure to send a pendrive or electronic evidence promptly and without proper safeguards, or non-production of seized materials before court, can critically impair the prosecution's case and may even lead to acquittal. Timely, transparent handling and proper documentation of evidence are vital in forensic and criminal proceedings.
In today's digital age, pendrives often hold crucial audio and video evidence in criminal cases. But what happens when prosecutors fail to send this pendrive to a forensic laboratory for analysis? Is non-sending pendrive to forensic laboratory fatal to prosecution? This question arises frequently in trials involving digital proof, raising concerns about evidence integrity, chain of custody, and procedural compliance.
Important Disclaimer: This article provides general information based on court judgments and is not legal advice. Consult a qualified lawyer for case-specific guidance.
Generally, the non-sending of a pendrive containing audio and video evidence to the forensic laboratory does not automatically render the prosecution case invalid or fatally flawed. Courts typically require substantial compliance with procedural safeguards, proper documentation, and no proof of tampering or contamination Mahesh Bhimraj Jadhav VS State of Maharashtra - 2023 0 Supreme(Bom) 1209.
Key factors include:- Intact seals and chain of custody: If seals remain unbroken and handling is documented, minor delays or non-transmission may not undermine the case State of Rajasthan VS Daul @ Daulat Giri - 2009 0 Supreme(SC) 858.- No evidence of prejudice: Without tampering or harm to the accused, procedural lapses are often overlooked Pravin VS Pooja - 2024 0 Supreme(Bom) 1091Udesh Shantaram Patekar vs Prakash Rajaram Surve - 2025 0 Supreme(Bom) 978.- Overall evidence strength: Credible witness testimony or other corroboration can outweigh forensic gaps Dasari Gottam Veeranna VS State of Andhra Pradesh, Represented by Public Prosecutor - 2017 Supreme(AP) 296.
Indian courts emphasize meticulous handling of digital and biological evidence. The Supreme Court has stressed that the integrity of evidence, especially biological and digital evidence, depends on proper collection, sealing, documentation, and preservation from seizure to analysis Mahesh Bhimraj Jadhav VS State of Maharashtra - 2023 0 Supreme(Bom) 1209. DNA or digital opinion evidence demands reliability, but delays or procedural lapses, if adequately explained and not resulting in contamination or tampering, do not necessarily invalidate the evidence or the prosecution case Mahesh Bhimraj Jadhav VS State of Maharashtra - 2023 0 Supreme(Bom) 1209.
For digital items like pendrives, guidelines focus on preventing alteration. Copying files without identification or delays in production aren't automatically fatal if integrity is preserved Pravin VS Pooja - 2024 0 Supreme(Bom) 1091Udesh Shantaram Patekar vs Prakash Rajaram Surve - 2025 0 Supreme(Bom) 978.
Numerous rulings affirm that non-sending or delays aren't per se fatal:
In a non-digital context with parallels, Criminal Appeal under IPC Sections 302/34, the court rejected the defense: We are not impressed with the submission... that non-sending of the arrow-head to the Forensic Science Laboratory is fatal to the case of the prosecution. When there is credible evidence on record... the failure... pales into insignificance Dasari Gottam Veeranna VS State of Andhra Pradesh, Represented by Public Prosecutor - 2017 Supreme(AP) 296.
NDPS cases reinforce this. In a conviction under Section 15 NDPS Act, delay in sending the sample to the Laboratory does not prove fatal to the prosecution case. The seals were intact as revealed by Ex.PJ, FSL report Avtar Singh VS State of Haryana - 2015 Supreme(P&H) 1039. Another noted a 7-day delay was explained as samples were returned for illegible seals and resubmitted Sandeep Kumar @ Bachi @ Malkiat Singh VS State Of Haryana - 2010 Supreme(P&H) 1318.
Pendrive-specific instances exist too. In a Kerala High Court matter, the prosecution sought forensic examination of a pendrive, and courts allowed it despite prior issues, without deeming non-sending fatal T N GOPI vs STATE OF KERALA. Punjab & Haryana HC dismissed objections to comparing audio/video from pendrive Ex.R1/A with forensic samples PAWAN KUMAR vs VINOD DUTT SHARMA.
Digital evidence demands extra scrutiny due to easy manipulation. Yet, courts clarify: The absence of a detailed chain of custody or delay in sending evidence, in the absence of evidence of tampering or contamination, is not necessarily fatal Pravin VS Pooja - 2024 0 Supreme(Bom) 1091Udesh Shantaram Patekar vs Prakash Rajaram Surve - 2025 0 Supreme(Bom) 978. The focus is whether the evidence has been handled properly and whether its integrity is preserved, not necessarily the timeliness alone Pravin VS Pooja - 2024 0 Supreme(Bom) 1091Udesh Shantaram Patekar vs Prakash Rajaram Surve - 2025 0 Supreme(Bom) 978.
In POCSO cases, even after a regional lab failed to retrieve data from mobiles/pendrives, courts permitted re-examination at state labs without invalidating proceedings NAVEEN vs STATE OF KERALA - 2026 Supreme(Online)(Ker) 9552. Himachal Pradesh HC allowed sending CDs/pendrives to Central Forensic Lab for data retrieval Sakthi @ Sakthiyendran vs The Inspector of Police.
Contrastingly, in some NDPS acquittals, unexplained 14-15 day delays with poor link evidence proved fatal: delay of 15 days, in sending the samples to the office of the Forensic Science Laboratory, and non-strict proof by the prosecution, that the same were not tampered with... must prove fatal Mohinder Singh VS State of Haryana - 2009 Supreme(P&H) 292KUNDAN SINGH vs STATE OF HARYANA. But these hinge on tampering risks, not non-sending alone.
Chain of custody is pivotal: The Supreme Court has emphasized that chain of custody must be maintained and documented to establish the integrity of biological and digital evidence Mahesh Bhimraj Jadhav VS State of Maharashtra - 2023 0 Supreme(Bom) 1209Pravin VS Pooja - 2024 0 Supreme(Bom) 1091. Failure to produce reports or delays don't invalidate if seals are intact and there is no indication of tampering State of Rajasthan VS Daul @ Daulat Giri - 2009 0 Supreme(SC) 858.
In NDPS contexts, non-production of seized materials can be fatal if unaddressed, but non-production of these commodities before the court is not fatal to the prosecution. The defence also did not insist during the trial Baijnath Mahto Son of Ram Chandra Mahto VS State Of Bihar - 2023 Supreme(Pat) 585.
Courts may rule against prosecution if:- Tampering evident: Mishandling, broken seals, or contamination proven State Of Haryana VS Kundan Lal - 2009 Supreme(P&H) 276.- Prejudice to accused: Delay affects reliability or defense preparation.- Strict protocols ignored: Especially for DNA/digital, non-compliance impacts admissibility Mahesh Bhimraj Jadhav VS State of Maharashtra - 2023 0 Supreme(Bom) 1209.
For instance, in an NDPS acquittal, 8-day delay with incomplete proof ruled out tampering possibility, proving fatal State Of Haryana VS Kundan Lal - 2009 Supreme(P&H) 276.
To safeguard cases:- Document collection, sealing, and custody meticulously.- Explain delays with evidence (e.g., returned samples) Sandeep Kumar @ Bachi @ Malkiat Singh VS State Of Haryana - 2010 Supreme(P&H) 1318.- Prioritize forensic sends but rely on holistic evidence.- Courts: Assess tampering/prejudice before dismissal.
In summary, non-sending a pendrive to the forensic lab is not automatically fatal to prosecution if integrity via seals, documentation, and no tampering is shown. Courts prioritize substance over minor procedural slips, as seen in Supreme Court and High Court rulings State of Rajasthan VS Daul @ Daulat Giri - 2009 0 Supreme(SC) 858Mahesh Bhimraj Jadhav VS State of Maharashtra - 2023 0 Supreme(Bom) 1209Dasari Gottam Veeranna VS State of Andhra Pradesh, Represented by Public Prosecutor - 2017 Supreme(AP) 296.
Key Takeaways:- Maintain chain of custody religiously.- Intact seals often save delayed evidence.- No tampering proof = case survives.- Digital evidence needs careful handling but isn't invalidated solely by non-forensic submission.

We are not impressed with the submission of the learned Counsel for the appellants that non-sending of the arrow-head to the Forensic Science Laboratory is fatal to the case of the prosecution. When there is credible evidence on record on the occurrence of offence and also regarding the manner in which the offence was committed by the appellants/accused, the failure of the investigating agency to send the arrow-head for forensic analysis, pales into insignificance. The evidence on record rules out any possibility of false implication of the appellants/accused and there is n....
In such a situation, delay in sending the sample to the Laboratory does not prove fatal to the prosecution case. The seals were intact as revealed by Ex.PJ, FSL report. It has been held by the Hon'ble Supreme Court in Hardip Singh versus State of Punjab, (2008) 8 Supreme Court Cases 557 that once it comes in evidence that till the date of parcels of samples are received by the Chemical Examiner, the seal is intact, said fact in itself proves and establishes that there was no tampering with the aforesaid seal in the sample at any stage and the sample received by the analyst ....
The argument that delay of 7 days in sending the samples to the Forensic Science Laboratory is fatal to the prosecution case, is again not tenable. It has come on record that the samples were sent earlier, but were returned for the reason that some of the seals are not legible. The samples were resubmitted after proper fixation of seals.
In Ramji Singh Vs. State of Haryana 2007(2) RCR (Criminal) 452 the sample was sent to the office of the Chemical Examiner after 72 hours, the seal remained with the police official, and had not been handed over to any independent witness. Under these circumstances, it was held that this circumstance would prove fatal to the case of the prosecution delay of 15 days, in sending the samples to the office of the Forensic Science Laboratory, and non-strict proof by the prosecution, that the same were not tampered with until the same were deposited in the Laboratory, must prove fatal to ....
The trial Court was, thus, right in coming to such a conclusion. The principle of law, laid down, in the aforesaid authorities, is fully applicable to the facts of the present case. The delay of 8 days, in sending the sample to the office of the Forensic Science Laboratory, and non-strict proof, by the prosecution, that the same was not tampered with, till it was deposited in that Laboratory, must prove fatal to the case of the prosecution, as the possibility of tampering with the same, could not be ruled out.
