A federal judge on Monday refused to throw out a lawsuit that accuses Rajakumara Rajaratnam, a former hedge fund manager convicted of insider trading, of aiding and abetting human rights violations by allegedly funneling millions of dollars to the Tamil Tigers, a Sri Lankan terrorist group.

Rajaratnam, his father Jesuthasan and the Tamil Rehabilitation Organization (TRO), a Sri Lankan NGO that raises money for the Tamil Tigers—whose full name is the Liberation Tigers of Tamil Elam—were sued under the Alien Tort Statute by more than two dozen Sri Lankan plaintiffs who claim they lost family members or were themselves injured in five bombings carried out by the Tigers in 2007 and 2008.
