This criminal appeal before the Calcutta High Court was filed by Ader Mondal and others against their conviction by the Additional Sessions Judge, Bongaon, for offences under Sections 498A/34 and 306/34 of the Indian Penal Code. The case arose from the death of Saima Khatun, who consumed poison on 2 March 2005 at her matrimonial home, allegedly driven to suicide by sustained physical and mental cruelty, an illicit relationship maintained by her husband, and persistent monetary demands made by the appellants. Her father (PW-1) lodged the complaint, and the prosecution examined ten witnesses to establish the continuous course of matrimonial cruelty. The trial court convicted appellant no. 1 to rigorous imprisonment of five years under Section 306/34 IPC and two years under Section 498A IPC, while appellants nos. 2 and 3 received three years and one year respectively under the corresponding charges. The judgment text provided covers the background and evidence led by the prosecution; the final appellate decision of the High Court is not captured in the excerpt provided.
