In Avendano-Hernandez v. Lynch, the U.S. Court of Appeals for the 9th Circuit ruled today that the Board of Immigration Appeals (BIA) made an error of law in denying protection under the Convention Against Torture (CAT) to a transgender woman from Mexico who had been sexually assaulted and raped by members of the Mexican police and military.  Apparently, an immigration judge and the BIA got it so wrong that it took an appeal to the Court of Appeals (a step below the Supreme Court) to reach the right decision.
