Dr. T. M. Thomas Isaac, the former Finance Minister, is one of the opposition party leaders who have come under the radar of the Enforcement Directorate (ED). The ED began serving summons to Dr. Isaac in July 2022 but has not been able to bring him in for questioning even once. Dr. Isaac challenged the legality of the ED’s notices in the High Court of Kerala. The Court asked the ED to explain the alleged offence and the necessity for questioning Dr. Isaac. However, to date, the ED has failed to provide any convincing explanation to the High Court. Consequently, they have not obtained approval to interrogate the former finance minister regarding his alleged involvement in the financial activities of the Kerala Infrastructure Investment Fund Board (KIIFBI). Dr Isaac is contesting to the Lok Sabha from Pathanamthitta constituency this time.
