The U.S. Supreme Court has already marked the day when it will hear oral arguments in the lawsuit over the constitutionality of the executive orders on immigration that President Obama announced in November 2014.
The hearing on the case of United States v. Texas will be held on Monday, April 18.
This week, the lawyers for the Administration filed a brief with the Supreme Court which argues that the case should not be before the courts and that the states in the lawsuit are trying to force the Supreme Court to decide on immigration policy - something that under the Constitution only belongs to the federal government. Therefore, the ruling of the federal Fifth Circuit Court of Appeals should be reversed.
The President's proposed expansion of the Deferred Action for Childhood Arrivals (DACA) and Deferred Action for Parents of American Residents or Citizens (DAPA) were blocked by a federal judge in Texas in February 2015, after several states filed suit to stop their implementation.
In November of last year, the federal Fifth Circuit Court of Appeals ruled in favor of upholding the stay on immigration relief, causing the Department of Justice to take the case all the way to the Supreme Court.
The Supreme Court is expected to announce its decision on the case in June.
