The U.S. Supreme Court on Wednesday waded into the emotionally weighted arena of international child abductions in a battle between Columbian parents of a little girl now living in the United States.

Lozano v. Alvarez is the third case in less than four years in which the justices have agreed to interpret provisions in the 1980 Hague Convention on international child abductions. As in the two earlier cases, the justices struggled with the often competing rights of the left-behind parent and the best interests of the child.
