Pen Drive FSL Exam: Mandatory for Evidence Admissibility?

In today's digital age, electronic evidence like videos on pen drives plays a pivotal role in criminal trials. But what happens when a pen drive containing crucial downloaded footages—such as CCTV recordings—is not sent to the Forensic Science Laboratory (FSL) for examination? This question often arises in cases involving authenticity disputes: pen drive in which footages were downloaded not sent for FSL.

Generally, courts emphasize strict procedures for handling electronic records to ensure their integrity. Failing to follow these may undermine the evidence's reliability. This post explores the legal requirements, key judgments, and practical implications, drawing from established case law. Note: This is general information, not specific legal advice. Consult a qualified lawyer for your case.

Why Forensic Examination of Pen Drives Matters

Electronic evidence, governed by Section 65B of the Indian Evidence Act, 1872, and the Information Technology Act, 2000, must prove its authenticity. Courts typically require the original device or a forensic clone to be examined at FSL to verify no tampering occurred.

The prosecution bears the burden to demonstrate a proper chain of custody: seizure, sealing, and forwarding to FSL. Without this, defense arguments on manipulation gain traction, potentially leading to evidence rejection. As seen in multiple rulings, FSL reports confirming no sign of editing are crucial for admissibility. Debeswar Taukdar, S/o. Late Kameswar Talukdar VS State of Assam, Represented by PP Assam - 2024 0 Supreme(Gau) 1482

Legal Obligation to Send Pen Drives to FSL

Legal documents consistently highlight the prosecution's duty to submit devices like pen drives for forensic scrutiny. Here's a breakdown:

Key Principles from Landmark Cases

• In one case, PW.15 from the Central Forensic Science Laboratory examined a USB flash drive and found no sign of editing was found in the video files, underscoring the need for device submission. Debeswar Taukdar, S/o. Late Kameswar Talukdar VS State of Assam, Represented by PP Assam - 2024 0 Supreme(Gau) 1482
• Another FSL report on a pen drive revealed three videos with notes on discontinuity and editing, relied upon by the court only because the device was properly analyzed. Nimba Ram, S/o. Shri Kushala Ram VS State of Rajasthan, Through Its Public Prosecutor - 2023 0 Supreme(Raj) 213

Courts have ruled that electronic evidence must be seized, sealed, and sent to FSL to maintain procedural fairness. Without this, authenticity is questionable. Sandeep @ Sandy VS State (Govt. of NCT of Delhi) - 2023 0 Supreme(Del) 5274Karan Singh Chohan vs Govt. of NCT of Delhi - Delhi (2019)

Chain of Custody Requirements

• Seizure and Documentation: Record the process meticulously.
• Sealing: Prevent tampering.
• FSL Submission: Essential for scientific verification.

Failure here invites adverse inferences, weakening the prosecution's case.

Consequences of Not Sending the Pen Drive to FSL

If the pen drive with downloaded footages skips FSL analysis:- Admissibility Challenged: Courts may deem it unreliable due to unverified integrity. Nimba Ram, S/o. Shri Kushala Ram VS State of Rajasthan, Through Its Public Prosecutor - 2023 0 Supreme(Raj) 213- Procedural Lapse: Violates evidence handling norms, as electronic records are documents under law, requiring certification. P. Gopalkrishnan @ Dileep VS State of Kerala - 2020 1 Supreme 82- Defense Advantage: Argue lack of credibility, potentially leading to acquittal.

For instance, in a case where CCTV data was transferred to a pen drive but the original hard drive/DVR wasn't supplied for FSL, further examination was demanded. BANSHILAL Vs. STATE OF RAJASTHAN - 2024 Supreme(Online)(RAJ) 1027

Insights from Additional Judicial Precedents

Broader case law reinforces this position:

• Multiple Sources Sent to FSL: In a Delhi High Court matter, two CDs and one pen drive containing video footages... were also sent to forensic lab, alongside materials from police, petitioners, and media, highlighting routine practice.

• Cloned Copies and Originals: Data from a memory card was saved to a pen drive and sent with the FSL report, ensuring verification. A pen-drive containing the data/visuals retrieved from the memory card, was also enclosed with the report sent by the State FSL.P. Gopalkrishnan @ Dileep VS State of Kerala - 2020 1 Supreme 82

• Authentication Failures: Prosecution failed due to unauthenticated CCTV footage without original data or FSL backing, leading to acquittal. Electronic evidence needs Section 65B compliance. Nirmal Seraphin vs The State Of Madhya Pradesh - 2025 Supreme(Online)(MP) 3470

• Supply to Accused: Accused must receive cloned copies for defense, balancing privacy. Contents of memory card/pen drive being electronic record must be regarded as a document.P. Gopalkrishnan @ Dileep VS State of Kerala - 2020 1 Supreme 82

• CCTV Transfers: Footage copied from DVR to pen drive then DVD was played in court, but lapses in seizing the pen drive were noted, though mitigated by witness testimony. State Of M. P. : Honey @ Kakku VS Honey @ Kakku : State Of M. P. - 2020 Supreme(MP) 250

• Other Contexts: In POCSO and murder cases, FSL-examined pen drives supported convictions, while unexamined ones raised doubts. Patan Mohammad Rafi VS State of Andhra Pradesh - 2020 Supreme(AP) 810Bhupesh @ Rinku s/o Vitthalrao Tichkule VS State of Maharashtra, through Police Station Officer, Sakkardara, Nagpur - 2018 Supreme(Bom) 768

These examples show courts' insistence on forensic validation across IPC, POCSO, and departmental inquiries. Dheeraj Singh Bisht VS Chairman Cum Managing Director, Punjab National Bank - 2022 Supreme(UK) 174RAJAL MAHADU GURUD AND ORS vs THE STATE OF MAHARASHTRA

Exceptions and Balancing Interests

While mandatory, courts may admit evidence if corroborated by strong witness testimony or other proofs. However, absence of FSL generally weakens electronic records. In privacy-sensitive cases (e.g., rape), inspection without copies may suffice, but forensic checks remain ideal. P. Gopalkrishnan @ Dileep VS State of Kerala - 2020 1 Supreme 82

Practical Recommendations for Prosecution and Defense

• Prosecution:
• Always seize, seal, and forward pen drives promptly to FSL.

• Obtain detailed reports on editing, continuity, and hash values.

• Defense:

• Challenge unexamined evidence on chain of custody grounds.

• Demand cloned copies under CrPC Section 207.

• Courts:

• Scrutinize procedural compliance before admitting digital evidence.

Conclusion and Key Takeaways

In summary, not sending a pen drive with downloaded footages to FSL typically compromises its evidentiary value, as courts prioritize forensic integrity for electronic records. Cases like Debeswar Taukdar, S/o. Late Kameswar Talukdar VS State of Assam, Represented by PP Assam - 2024 0 Supreme(Gau) 1482 and Nimba Ram, S/o. Shri Kushala Ram VS State of Rajasthan, Through Its Public Prosecutor - 2023 0 Supreme(Raj) 213 illustrate that FSL examination is often indispensable.

Key Takeaways:- Follow chain of custody rigorously.- FSL reports bolster admissibility.- Non-compliance may lead to evidence rejection.
