A ruling of the US Court of Appeals in New Orleans on November 9th to put a stay on Barack Obama’s executive action (a kind of presidential decree) on immigration has left one of the president’s most consequential policies in a tight spot. The verdict, reached by a 2-1 margin, upheld an earlier ruling by a district court in Texas, and was anticipated, given the appeals court’s previous deliberations on aspects of Mr Obama’s plan. Launched by executive fiat in November 2014, it includes a promise of temporary reprieve from deportation to those who have lived in the country undocumented since childhood and to anyone who has lived in the country since 2010 and whose children are American citizens.Together those groups represent a third of the 11m people estimated to be living in America without a legal right to do so. Republicans, who had repeatedly nixed a proposed legislative solution to that grave problem, mostly denounced Mr Obama’s alternative effort as an unconstitutional and tyrannical act designed to swell the Democratic vote-bank. The administration has already declared its intention to appeal against the latest ruling to the Supreme Court, which is not guaranteed, but would be expected, to take up the case. If this happened, the administration believes it would be on firm ground. Assuming it takes up the case, the court would be expected to rule on it towards the end of its current term, next June. If it rules in his favour, Mr Obama would then have a few months to try hurriedly to implement a plan that most of the Republican candidates for their party’s presidential nomination have pledged to scrap.

In my opinion, Mr. Obama is, while well in his rights, going into waters that shouldn’t be gone into. With an upcoming election, if he wants any chance of a democrat being elected so his plan will continue out, this is not smart. It’s a good plan, but highly predictable and in politics, predictable is not the route you want to take. Now, the Republican candidates will be one step ahead of the democrats with a guaranteed, “I will without a doubt tear apart Obama’s immigration plan.” It is not a popular plan in the world of politics, therefore, when a few candidates take this road, it will easily be taken down.
