A lawyer on Thursday filed a petition in the Supreme Court, seeking judicial intervention with the government to ensure security measures are put in place in courts across the country.

Advocate Ajay Agarwal said he was an eyewitness to Wednesdays blast at the Delhi High Court.

This petition is being filed for the lapses of the government and police authorities in providing security and taking up appropriate steps for the prevention of lives of the people, the petition said.

The four primary parties arrayed in the petition are the Cabinet Secretary, the Home Secretary, Chief Secretary of Delhi and Delhi Police Commissioner. It has also made all states parties through the chief secretaries.

The petition sought the court to direct the government to immediately take steps to ensure appropriate security installation of CCTV cameras and other necessary gadgets in all courts.

The petition also wants the Centre and the Delhi government to take appropriate action against the erring and negligent officers of Union government, Delhi government and Delhi Police for not installing CCTV cameras for the last three years despite having strong recommendation to do so and even after the May 25, 2011 blast outside Delhi High Court.

It also wants the government to file status reports on prevailing security at courts.
