WASHINGTON, D.C. - The U.S. Supreme Court on March 10 declined to hear the appeal of a June 2013 decision by the District of Columbia Circuit U.S. Court of Appeals upholding the rejection of two cases by pilots challenging the nonretroactivity provision of a federal rule that extended the maximum age for piloting commercial flights by five years (George Emory, et al. v. United Air Lines, Inc., et al., No. 13-826, U.S. Sup.; 2014 U.S. LEXIS 1870).
