The Justice Department said Monday it will not appeal a federal court decision that allowed the Palestine Liberation Organization mission at the United Nations in New York to remain open.

The department said in a statement that the "decision was based on a determination that, on balance, the interests of the United States are best served by not appealing."Congress had sought to force the closing of the PLO mission at the U.N. on the grounds that the PLO endorsed terrorism.

But the State Department objected on the grounds that closing the office would violate the U.N. Headquarters Agreement. The U.N. also objected.

On June 29, U.S. District Court Judge Edmund Palmieri accepted that view. He said the Anti-Terrorism Act of 1987 did not require closing the PLO office in New York because Congress "did not clearly indicate its intent on the face of the statute to violate U.S. obligations under the U.N. Headquarters Agreement."
