Defiant Campa Cola residents today thwarted attempts by municipal authorities to cut off essential supplies to the illegal flats, blocking their entry into the compound by locking up the gates and forming human barricades. In a U-turn, the Campa Cola Housing Society here told the Bombay High court today that it was ready to file a fresh plea for deemed land conveyance before the Deputy Registrar of Cooperative Societies and to make Municipal Corporation of Greater Mumbai a party.
