The Obama administration is checking into the possibility of challenging the split decision by the Supreme Court last week,
Attorney Gen. Loretta Lynch told Reuters.
The decision left in place a block by the lower court on the president's executive action that would grant work permits and legal status to millions of illegal immigrants
"We will be reviewing the case and seeing what, if anything else, we need to do in court," Lynch said.
The Daily Caller said that following the tie in the Supreme Court decision, both sides in the litigation have the right to appeal for a rehearing, which must be filed within 25 days of a ruling. At least five justices must agree for the case to be reheard.
Lynch also said that any further decisions about executive action on immigration will be made by the White House.
Obama's plan was to allow some four million people who have been living illegally in the U.S. since at least 2010 but have lawful children and no criminal record enter a program that prevents them from being deported and grants them work permits.
Some experts say the court decision appears to indicate that any major immigration policy dealing with the approximately 11 million illegal people in the U.S. would have to be enacted by Congress and not through an executive order.
