A federal appeals court on Monday ruled against President Obama’s plan to shield up to 5 million undocumented immigrants from deportation, dealing another blow to the administration’s effort to remake immigration laws and likely setting up a final battle in the Supreme Court next year. A White House official said the administration strongly disagreed with the court decision and was reviewing its legal options. “Today’s ruling is a slap in the face to the good people in America who have also been waiting for Congress and the courts to act with justice, humanity and common sense on the issue of immigration reform,” said Angelica Salas, executive director for the Coalition for Humane Immigrant Rights of Los Angeles.
