The Supreme Court today took note of 21 state governments' failure to file replies to a plea for setting up a high-powered Civil Service Board to decide transfer and postings of civil servants and rid bureaucracy of political interference, corruption and inaction. On being told that out of 36 respondents, only 15 states, including the Centre, have responded to its notices, a Bench of Justices K S Radhakrishnan and Dipak Misra directed the 21 states to file their responses in one month. The court also asked the Centre to file a status report after considering the replies of all the state governments on issues raised in the PIL and fixed February 20 for further hearing.
