NEW DELHI: The use of red beacon could well be restricted to only five Constitutional dignitaries at the Centre and four in the states. Road transport minister Nitin Gadkari has sought views of key Union ministers on the issue before a final proposal is put in place.Gadkari has reportedly favoured limiting the privilege to President, Vice-President, Prime Minister, Speaker and Chief Justice of India at the Centre. In line with this norm, use of red beacon could be limited to governor, CM, assembly speaker and chief justice of the high court in states.Sources said Gadkari has written to his Cabinet colleagues, including home minister Rajnath Singh, finance minister Arun Jaitley and external affairs minister Sushma Swaraj, to give their opinion. While detailing the process since the SC came out with its stinging remark on limiting the use of beacon lights in September 2013, Gadkari has attached all the communication among different ministries. He has also forwarded legal opinion and suggestions his ministry has received so far.“Only after the key ministers give their views, a formal proposal will be put before the government. It will take some time. But one thing is clear that the number of such dignitaries would be limited. Once this happens, there has to be strict enforcement and stringent penalty against violators,” said a government source.
