High Court decision edit

The Bench was headed by High Court Judge Shiran Gunaratne, who was of the view that all 13 accused were innocent and should be cleared of all charges, his reasons being lack of integrity of the witnesses produced at the case by the prosecution, and the inability to prove charges beyond reasonable doubt. Fellow High Court judges M.C.G.S. Morais and Judges Padmini Ranawaka Gunathilaka, issued the death sentence to Duminda Silva and four others, rejecting the argument put forward by the defence during trial that Silva had been shot at first by the Premachandra group. The verdict was delivered on September 8 2016.^[3][4][5][6]

Courts then acquitted and discharged eight of the accused, namely; Chandana Jagath Kumara, Lanka Rasanjana, Malaka Sameera, Widanagamage Amila, Suranga Premalal, Saman Kumara, Saman Abeywickrema and Rohana Marasinghe.
