A lawsuit accusing a Wall Street hedge fund manager and his father of using a charitable foundation to funnel millions of dollars to the Tamil Tigers, a Sri Lankan terrorist group, can go forward, a federal judge in New Jersey says.

The suit, filed under the Alien Tort Claims Act, concerns the Tamil Rehabilitation Organization (TRO), a non-profit that the U.S. Treasury Department shut down in 2007 for allegedly bankrolling the Liberation Tigers of Tamil Elam (aka Tamil Tigers), which the U.S. classified as a foreign terrorist organization in 1997 and as a specially designated global terrorist in 2001. TRO’s assets were frozen and Americans were barred from dealing with it.
