The Miami Herald reports lawyers for so-called Australian Taliban David Hicks — the first man to trade a Guantánamo guilty plea for his freedom — appealed that conviction Wednesday in an argument that invokes a civilian-court ruling that disqualified providing material support for terrorism as a war crime. Hicks, 39, a self-styled soldier of fortune from Adelaide, Australia, who at one point converted to Islam, was captured in Afghanistan early on in the U.S. invasion following the 9/11 attacks. He was brought to Guantánamo the day it opened, Jan. 11, 2002, and pleaded guilty in 2007 in exchange for his release. He is now back home. His lawyers called his guilt “illusory” in a summary of their filing, which was still under seal at the U.S. Court of Military Commission Review. In July, a federal court nullified the material support and solicitation convictions of Ali Hamza al Bahlul, a Yemeni captive still at Guantánamo.
