Forensic Report Not Submitted with Police Final Report: Legal Consequences for the Accused

Introduction

In criminal investigations, forensic science reports play a pivotal role in establishing evidence linking the accused to the crime. But what happens when the original forensic science report is not submitted alongside the police final report to the court? This question—Forensic Science Report Original Not Submitted with Police Final Report to the Court Legal Consequences for Accused—raises critical concerns under Indian law, particularly Section 173 of the CrPC, which governs the submission of police reports.

The absence of such crucial evidence can create procedural hurdles, weaken the prosecution's case, and potentially benefit the accused. This blog post explores the legal implications, drawing from key case laws and principles. Note: This is general information and not specific legal advice. Consult a qualified lawyer for your case.

Key Legal Principles on Evidence Submission

Under Indian criminal procedure, the police must submit a complete final report (chargesheet) under Section 173 CrPC, including all relevant documents and evidence. Forensic science laboratory (FSL) reports are often essential for proving the nature of seized materials, signatures, fingerprints, or other scientific links to the crime.

Admissibility of Evidence

Courts scrutinize the admissibility of scientific evidence. Without the original FSL report, the prosecution may struggle to meet the burden of proof. In N.P. Jharia v. State of M.P., the court stressed the need for proper investigation and submission of forensic reports to substantiate charges. 2023 5 Supreme 15 2012 4 Supreme 481

The lack of forensic evidence raises doubts about reliability. For instance, if drugs or substances are seized but not chemically verified via FSL, the chain of evidence breaks. In State v. Jitendra, non-production of seized drugs and absent forensic evidence undermined the case. 2003 7 Supreme 68

Procedural Irregularities

Failure to include the FSL report constitutes a procedural lapse. Courts have vitiated proceedings for such omissions. In Bhagwant Singh v. State of Punjab, the Supreme Court highlighted flaws in accepting final reports without proper notice or documents. 1998 5 Supreme 329

From additional judicial observations, courts note that while FSL reports are vital, their delayed or non-submission doesn't always invalidate the entire report if the investigation is otherwise complete. However, in cases like one where the Forensic Science Laboratory report was not submitted to the court or not, it is not forthcoming, this absence questions the prosecution's claims, such as whether seized ganja was properly identified. 2020 0 Supreme(Kar) 947

Another example: But the Forensic Science Laboratory report was not submitted before the Trial Court. This lends support to the case of the defence that it is a case of accidental burns. 2015 0 Supreme(Kar) 979

Impact on the Prosecution's Case

The prosecution must prove guilt beyond reasonable doubt. Missing FSL reports create gaps:- Reasonable Doubt: Courts apply the benefit of doubt principle if key evidence is absent. 2012 2 Supreme 196- Incomplete Investigation: Judges can reject final reports under Section 173 CrPC if materials suggest incompleteness. For example, If the court is of the opinion that the materials collected by the police in the report submitted under section 173 of Cr. 2024 0 Supreme(Kar) 274

In 2025 Supreme(Online)(TEL) 4060, the court considered an FSL opinion on signatures dated 13.05.2014, stating the person who wrote the red enclosed signatures marked S1 and S58 also wrote the... but noted delays in submission. 2025 Supreme(Online)(TEL) 4060

Similarly, in cases where permission was sought from civil courts for original deeds before FSL analysis, non-submission affected charge sheets: Apart from this, it is also clear from the record that before sending the alleged forged deed for the FSL report, permission to obtain the original deed was received... 2023 0 Supreme(All) 1093

Courts may order further investigation or accept reports if no cognizable offense is evident, as in negative final reports: negative final report was submitted by the SHO... 2025 Supreme(Online)(Raj) 13812

Legal Consequences for the Accused

The non-submission often favors the accused:- Potential Acquittal: If the case relies heavily on forensics, lack of report leads to acquittal due to insufficient evidence. 2012 5 Supreme 260- Benefit of Doubt: Prosecution fails to establish a prima facie case. 2012 2 Supreme 196- Grounds for Appeal: Convictions despite omissions provide appeal grounds on procedural irregularities. 2020 1 Supreme 82

However, absence doesn't guarantee acquittal; courts assess totality of evidence. In 2024 Supreme(Online)(Guj) 27801, examination was limited to case diary and final report, even without full forensics. 2024 Supreme(Online)(Guj) 27801

Other impacts include:- Bail Considerations: Weak evidence strengthens bail pleas.- Trial Delays: Courts may direct FSL submission, as in On receipt of the forensi.... 2025 Supreme(Online)(Mad) 25180- Report Rejection: Magistrates can reject incomplete reports, e.g., in the Final Report by not accepting the Final Report... 2025 0 Supreme(Gau) 1267

In 2016 0 Supreme(Ker) 823, a final report was deemed inadmissible due to investigation by non-empowered officers, compounded by missing forensics: This legal infirmity... was not considered... therefore the final report is not admissible. 2016 0 Supreme(Ker) 823

Defense Strategies and Court Discretion

Defense counsel should:1. Highlight the omission during arguments.2. Argue for discharge or quashing under Section 227/239 CrPC.3. Seek benefit of doubt.

Courts exercise discretion: Filing of subsequent supplementary challan... would not affect the status of earlier filed Final Police Report. Mere recital... Report of the Forensic Science Laboratory had to be obtained, would not... make the Police Challan... incomplete. 2008 0 Supreme(J&K) 426

In 2024 Supreme(Online)(MAD) 14473, police filed final reports post-investigation, resisting quashing. 2024 Supreme(Online)(MAD) 14473

Conclusion and Key Takeaways

Non-submission of original forensic science reports with police final reports can significantly weaken prosecutions, offering the accused avenues like acquittal, appeals, or discharge. While not always fatal—especially if other evidence suffices—it underscores procedural rigor under CrPC.

Key Takeaways:- Always demand FSL reports in defense.- Courts may reject incomplete reports or order supplements.- Totality of evidence matters; forensics are crucial but not sole deciders.
