A vote in the Supreme Court on President Barack Obama’s immigration reform plan, which would have protected millions of people from deportation, has ended in a tie. The 4-4 vote leaves the lower court’s ruling in place, effectively blocking Obama’s plan until the end of his administration.

According to the Associated Press, the 5th U.S. Circuit Court of Appeals, in New Orleans, has ruled against President Obama’s plan to protect an estimated 5 million people living in the United States illegally from deportation.
