The LDF, which has been raising the issue right from the beginning of the session, disrupted proceedings today during the final discussion of the Finance Bill moved by Mani.
The Minister could not complete his reply as LDF members moved to the well of the House and continued raising slogans against the government.
As the protest continued, the House passed the Finance Bill, The Kerala Anti-Social Activities (Prevention) Amendment Bill-2014 and The Kerala State Road Transport Corporation Bill 2014, following which Deputy Speaker N Sakthan adjourned the House sine die.
CPI(M) Deputy leader Kodiyeri Balakrishnan alleged that the government was trying to scuttle the investigation.
Later, opposition members stormed out of the Assembly.
Speaking to reporters, LDF leaders said they would continue their agitation outside the House, demanding Mani's resignation.
