Earlier this month, acting on a PIL filed by advocate D K Garg, the court had asked the Centre to outline the steps taken by it to ensure the safety of Indian students in Australia. The PIL had accused the government of inaction in dealing with the attacks. Filing its reply last week, the Centre had assured of the diplomatic efforts taken at the highest level as it described how Prime Minister Manmohan Singh had raised the issue with his Australian counterpart Kevin Rudd on May 29. It informed the court that the Australian government was exploring the possibility of amending its existing laws to enhance punishment for racism-related offences.
