From the article:

A Texas group sued the Federal Aviation Administration in federal court to challenge the agency’s order to stop using drones in the group’s searches for missing people, the latest round in an intensifying battle over regulation of the sector.

Search-and-rescue organization Texas EquuSearch, which has used unmanned aircraft to help search for missing people since 2006, asked the U.S. Court of Appeals for the D.C. Circuit to set aside the FAA’s order to halt its use of drones. The group argued in a five-page petition filed on Monday that the FAA’s order has no legal basis and “is unlawful, arbitrary, capricious, an abuse of discretion and not otherwise in accordance with law.”
