The United Nations International Court of Justice has rejected the Marshall Islands’ bid to sue the United States and other nuclear powers for violating the 1968 Nuclear Nonproliferation Treaty.

The Marshall Islands chain, which includes Bikini Atoll, was the subject of dozens of U.S. nuclear tests in the 1940s and 1950s, which have left lasting health and environmental impacts.

The Pacific Island nation filed the suit in 2014, but it was rejected Wednesday after the court said it did not have jurisdiction over the case.
