A PIL has been moved in the Delhi High Court demanding cancellation of the registration of the Communist Party of India (Marxist) as a political party. The petition, which came up for hearing before a bench of Acting Chief Justice Gita Mittal and Justice C Hari Shankar, has sought quashing of the Election Commission's September 1989 order granting registration to the CPI(M). The high court has listed the matter for further hearing on March 28 next year on the request of the counsel for the petitioner.
