The U.S. Justice Department will seek to dismiss at least 180 cases brought by detainees held at the U.S. military's detention center at Guantanamo Bay, Cuba.
The prisoners' lawsuits challenge the legality of their confinement at the prison.
Justice Department officials notified judges presiding over the cases at the U.S. District Court in Washington that official motions to dismiss the lawsuits will be filed.
Legislation signed by President Bush last week curbs U.S. civilian courts' abilities to hear detainees' cases.
About 500 prisoners are held at Guantanamo, most of them captured in Afghanistan on suspicion of ties to the Taleban or al-Qaida.
