The Ontario Court of Appeal has upheld the extradition of two Canadians wanted in the United States for allegedly helping supply arms to the LTTE.

Pratheepan Nadarajah and Suresh Sriskandarajah had challenged a 2009 lower court ruling that found there was sufficient evidence to justify their extradition, the National Post reported.

But in decisions handed down on December 17, the court dismissed their appeals, opening the door for their transfer to New York to stand trial on terrorism-related charges.

“The evidence against Sriskandarajah, while mostly circumstantial, was extensive,” the judges wrote. “The extradition judge correctly assessed that evidence as a whole.”

U.S. prosecutors have charged Nadarajah with attempting to buy $1-million worth of missiles and AK-47s for the LTTE.

Sriskandarajah, also known as “Waterloo Suresh,” is accused of laundering money and conspiring to procure equipment for the terrorists.

Both men were arrested in 2006 following a joint RCMP FBI investigation called Project ONeedle. Three other Canadians have already pleaded guilty to involvement in the missile plot. A sixth Canadian who allegedly conspired with Sriskandarajah, Ramanan Mylvaganam, has already been extradited.
