Chief Minister Karunanidhi has threatened to go on a fast from his hospital beds if the stirr created by the lawyers of Madras High Court and other courts continue without reaching any amicable settlement."Whether I need to go on fast is based on the decision you take," he said. Ignoring the continuous calls of justice K G Blakrishnan and others, the lawyers have decided to continue with their agitation and they resolved to boy cotting of all courts and dismissal of state and city police chiefs. The developments on Sunday came after the Madras High Court directed the City police to name on whose authority its force entered the court and latjicharged lawyers, causing destruction to life and property.
