The high court had earlier ordered that the four TMC leaders be kept under house arrest instead of jail. The four politicians of West Bengal accused in the case are two sitting ministers of Mamata Banerjee-led government - Firhad Hakim and Subrata Mukherjee - and TMC legislators - Madan Mitra and former MLA Sovan Chatterjee. The high court had earlier referred the bail pleas of these four leaders to be heard by a five-judge larger bench after the split verdict was passed by the two-Judge bench. On May 24, the Central Bureau of Investigation (CBI) had filed a Special Leave Petition (SLP) before the Supreme Court challenging the Calcutta High Court`s order which allowed the house arrest of four Trinamool Congress (TMC) leaders. It later withdrew its appeal.
