Three criminal appeals were heard together before the Calcutta High Court, arising from a common judgment of conviction dated June 27, 2019 passed by the Sessions Court in Sessions Trial No. 10 of 2012. The appellants — Md. Mujahid Khan, Md. Chand @ Sahabaj Akhtar, and Md. Samim — were convicted under Sections 302/201/34 of the Indian Penal Code, 1860 for the murder and concealment of the body of one Javed Ali @ Jahid, who was allegedly lured to Khan Marriage Hall on January 27, 2011 and killed. The appellants challenged the conviction on grounds including failure to establish a complete chain of circumstantial evidence, unexplained time gap between the 'last seen' evidence and recovery of the dead body, material contradictions in witness testimonies, and non-proof of motive. The State defended the conviction, relying on the 'last seen' doctrine under Section 106 of the Indian Evidence Act, 1872, and the reliability of relative witnesses. The judgment text provided does not record the final appellate decision, as it concludes mid-narration of the prosecution evidence.
