Bipin Kumar Mondal v. State of West Bengal — Post-mortem corroboration of family eyewitness

Part of the Forensic Docket on Legal Desire Forensics — a conviction confirmed through final appeal, kept here as a method-of-crime record.

The facts

The appellant was accused of stabbing his wife and son to death; another son (PW-1), while trying to intervene, was also injured.

He was convicted under Sections 302 and 323 of the Penal Code.

On appeal, it was argued that PW-1’s testimony should not be relied upon.

The Supreme Court held that there was nothing to show that PW-1 had any reason to falsely implicate his own father, and that his account was natural, probable and convincing.

Other witnesses — close relatives and neighbours who reached the spot after hearing PW-1’s shouts — also supported the prosecution’s case, and the ocular evidence was duly corroborated by the post-mortem report.

The courts below were held right in convicting the appellant.

Status: conviction upheld through final appeal.

Why this belongs in the Forensic Docket: Family-on-family violence cases often hinge on whether a surviving relative-witness can be trusted; here it was the fit between that testimony and the post-mortem findings, not the relationship alone, that carried the conviction.
