FALLS CHURCH, Va. (AP) — A panel of federal appellate judges expressed concerns about ordering revisions to a government watchlist of roughly 1 million individuals labeled as “known or suspected terrorists,” despite a lower court finding that the list was constitutionally flawed. The 4th U.S. Circuit Court of Appeals in Richmond, Virginia, heard arguments Tuesday on the constitutionality of the watchlist. Government lawyers urged the judges not to intervene in the list’s administration. They argue that the problems encountered by those on the list, like enhanced screening at airports, were too insignificant to merit intervention on constitutional grounds. Opponents of the watchlist say the burdens are significant for those who must live with them and that most are on the list for no good reason.
