Section 306 IPC | Handwriting Expert's Report Inadmissible Under Section 293 CrPC Without Examining Expert: Supreme Court

"Such reports are not admissible under Section 293 CrPC (corresponding to Section 329 of the Bharatiya Nagarik Suraksha Sanhita, 2023) and hence, have to be proved as any other report by examining the expert in evidence." Supreme Court has held that a handwriting expert's report cannot be relied upon to prove the authorship of disputed documents without examining the expert as a witness, as such opinions do not fall within the statutory remit of Section 293 CrPC.

A Division Bench comprising Justice Sandeep Mehta and Justice Devendra Kumar Upadhyaya set aside the conviction of a husband under Section 306 IPC, ruling that an accused's failure to specifically deny an incriminating document in their Section 313 CrPC statement cannot substitute substantive legal proof.

The appellant and the deceased were married in 1996, but following severe matrimonial discord, she began residing separately at her parental home in February 2009 while pursuing criminal cases under Section 498-A IPC and the Domestic Violence Act. On January 18, 2011, the deceased died of burn injuries sustained at her parental residence, which the prosecution alleged was suicide induced by four threatening letters sent by the appellant. Relying on an uncorroborated handwriting expert report and the appellant’s omission to deny authorship under Section 313 CrPC, the trial court convicted him under Section 306 IPC, a decision subsequently affirmed by the Rajasthan High Court.

Whether a handwriting expert's report is admissible in evidence under Section 293 CrPC without examining the expert and subjecting their opinion to cross-examination?

Whether the omission of an accused to specifically deny the authorship of a disputed document in their statement recorded under Section 313 CrPC discharges the prosecution from proving its case beyond reasonable doubt?

Whether letters sent by an estranged spouse containing abrasive language alongside pleas for reconciliation constitute proximate instigation to commit suicide under Section 306 read with Section 107 IPC when the parties lived apart for years?

Expert handwriting opinion is not admissible under Section 293 CrPC without examining the expert witness in court

Scrutinizing the evidentiary foundation of the case, the Court observed that the prosecution primarily hinged its case on four postcard letters allegedly written by the appellant to show instigation. However, the prosecution failed to examine the handwriting expert who authored the forensic opinion. The Bench noted that handwriting comparison is an inherently imperfect science requiring rigorous testing.

The Bench held that testing the opinion on the anvil of cross-examination is indispensable before placing any judicial reliance upon it. Emphasizing the limits of statutory exceptions to oral proof, the Court underscored:

"Thus, if, at all, the prosecution wishes to rely upon the report of a handwriting expert in order to prove and attribute the handwriting on a particular document to that of another person, it is essential to examine the handwriting expert in evidence because handwriting comparison is not a perfect science and may be the subject matter of different interpretations... Such reports are not admissible under Section 293 CrPC (corresponding to Section 329 of the Bharatiya Nagarik Suraksha Sanhita, 2023) and hence, have to be proved as any other report by examining the expert in evidence."

Prosecution cannot derive strength from an accused's omission to deny documents under Section 313 CrPC

The Court rejected the concurrent findings of the lower courts that the appellant had not explicitly denied authoring the letters during his examination under Section 313 CrPC. The Bench reiterated that criminal jurisprudence requires the prosecution to stand entirely on its own legs and prove every foundational element of guilt.

A perceived deficiency in the defence cannot serve as a proxy for legal evidence. Addressing the evidentiary scope of an accused's examination, the Court remarked:

"The statement of the accused under Section 313 CrPC is required to be considered in its entirety, and any omission to specifically deny a particular circumstance cannot, by itself, establish the authorship of a disputed document."

Unexplained delay in lodging complaint and absence of suicide claims during inquest undermine prosecution case

The Bench also noted significant contradictions surrounding the origin of the fire, highlighting that the sister of the deceased initially told the hospital that a sudden fire broke out while she was alone. Contemporaneous police wireless entries and duty registers referenced an accidental gas cylinder or electrical short circuit.

Furthermore, the father and brother of the deceased gave statements during the inquest under Section 174 CrPC without indicating that she committed suicide. The complainant mother approached the magistrate under Section 156(3) CrPC fifteen days after the incident without explaining the delay, leading the Court to find the allegation of suicide-inducing letters an afterthought.

Offensive communications seeking reconciliation do not constitute proximate instigation under Section 107 IPC

Even assuming the appellant authored the letters, the Bench observed that they had to be evaluated in their entirety and surrounding context. While the letters contained offensive language, they simultaneously contained fervent appeals for the deceased to withdraw pending proceedings and resume cohabitation.

Crucially, the Court determined that the essential ingredients of abetment under Section 107 IPC were wholly absent, as the deceased had lived away for over two years while actively pursuing litigation against the appellant:

"Admittedly, the deceased had left the company of the appellant and was living at her father’s house for the last more than 2 years of the incident. She had instituted litigation against the appellant and was pursuing the same actively. Hence, the letters by themselves cannot be construed to be the instigating material which was the immediate cause for the victim to have committed suicide."

The Supreme Court allowed the appeal and set aside the judgments of conviction and sentence rendered by the trial court and the High Court. The appellant was acquitted of the charge punishable under Section 306 IPC, and his bail bonds were discharged.
