Referring to the appointment of retired Madras High Court judge R Reghupathy as the head of the commission, Karunanidhi in a letter in his party organ "Murasoli" said no timeframe had been fixed for submission of its report.
"Ommission of the timeframe itself gives the impression that the appointment of the commission is an eyewash..", Karunanidhi alleged in his statement.
Meanwhile, DMK Chennai and Kancheepuram district units today announced a 'Rajbhavan March' on July 12 to condemn the state government for approving the building plan and demanding a CBI probe, a party release said.
