A unanimous U.S. Supreme Court ruled this week that federal courts have no jurisdiction to review the U.S. homeland security secretary's decisions to revoke visas for what he or she concludes "to be good and sufficient cause."

In its 9-0 decision, the high court said Congress expressly gave the secretary unreviewable revocation discretion in the Immigration and Nationality Act. Individuals with revoked visas can petition again to U.S. Citizenship and Immigration Services and, if denied, can seek judicial review of the denial, the justices added.
