Volz’s defence team immediately appealed his conviction. Several members of the American government investigated the case and made appeals on Volz’s behalf and the Free Eric Volz movement continued to advocate for his release in the United States. On 17 December 2007 a three-judge panel overturned Volz’s conviction and set him free. Despite the ruling, some in the Nicaraguan judiciary seemed determined to keep Volz in prison. The prosecution tried to appeal the decision and the trial judge, Ivette Turuno Blanco, who had to sign the papers releasing him, did not come to work on the afternoon she was supposed to perform the task or for several days thereafter. Eventually, Volz’s mother appealed to the courts to free her son and an appeals court signed the release papers. On 21 December 2007, after over a year in jail, Volz was freed.
Many Nicaraguans were still very much against Volz and had been suggesting he had only been released because of US government pressure. Fearing vigilante justice and reportedly suffering mentally and physically from his year in jail, Volz left Nicaragua the afternoon he was released from prison.
