In what could be a first of its kind, five members of the Kerala Legislative Assembly have approached the Kerala High Court by way of a public interest litigation (PIL) petition against the ongoing Enforcement Directorate probe into the financial transactions of the Kerala Infrastructure Investment Board (KIIFB)..Communist Party of India (Marxist) MLAs KK Shailaja, IB Satheesh and M Mukesh, Communist Party of India MLA E Chandrasekharan and Congress (Secular) MLA Ramachandran Kadannappally have moved the PIL.The plea is posted for hearing today before a division bench of Chief Justice S Manikumar and Justice Shaji P Chaly..Dr. Thomas Issac, former Kerala Finance Minister and member of the Communist Party of India (Marxist), has also approached the Court with a separate plea challenging the summons issued by the ED in the same case.That matter will be heard today by single-judge Justice VG Arun. .Both petitions have argued that the ED is conducting a fishing and roving exercise to discredit the KIIFB, which in turn would discourage its investors. The petitions assume significance in the backdrop of opposition parties alleging that the BJP government at the Centre has been misusing the agency to target State leaders and topple State governments. Sitting and former ministers of at least 5 States - West Bengal, Maharashtra, Delhi, Jharkhand and Kerala - are facing ED probe in relation to various cases. The recent judgment of the Supreme Court upholding stringent provisions of the Prevention of Money Laundering Act has also come under fire from opposition leaders.
