A public interest litigation filed in the Supreme Court of India says that Indian military personnel took direct part in the war in Sri Lanka in 2009 and that some were even injured in battle.

The Times of India reports that the PIL, citing eyewitness evidence and an international probe, says that a Sikh Officer was commanding Indian forces in Sri Lanka in 2009.

Noting that the deploying of the Indian military without parliamentary of presidential approval is illegal, the litigation seeks the establishment of a special tribunal to probe and prosecute persons who were behind the “illegal war”, besides compensation to the immediate families of the victims.

The petition was filed by Delhi-based advocate Ram Sankar, secretary of the Delhi Tamil Advocates Association, last week. It is due to be taken up on April 17.

According to The Times of India report, the petition says that Indian Army, Navy and Air Force personnel “were unlawfully sent to Sri Lanka to aid and abet the Sri Lankan forces.”
