WASHINGTON, D.C. - The federal government on Jan. 3 filed a brief with the U.S. Supreme Court opposing an emergency injunction pending appellate review or, in the alternative, a petition for a writ of certiorari before judgment and injunction pending resolution following a Dec. 31 order by Justice Sonia Sotomayor that temporarily blocked the federal government from enforcing the birth control mandate contained in the Patient Protection and Affordable Care Act (PPACA) against an order of Catholic nuns at the request of the group after a lower court denied a motion for a preliminary injunction in a case challenging the mandate (Little Sisters of the Poor Home for the Aged, et al. v. Kathleen Sebelius, et al., No. 13A691, U.S. Sup.).
