 According to the brief, government documents that surfaced after Rubashkin's conviction and not made available to the defense showed that Reade was involved in the planning for the federal immigration raid of the Postville plant in May 2008, which it sees as collusion with the prosecution.Reade′s "excessive coziness" with prosecutors planning the raid raised doubts about her impartiality in the case, the brief claims, and states that as a result Reade should have recused herself, and that Rubashkin is entitled to a new trial or, at a minimum, an evidentiary hearing.Following the filing of this appeal, the American Civil Liberties Union (ACLU), National Association of Criminal Defense Lawyers (NACDL) and Washington Legal Foundation (WLF) filed amicus briefs supporting Rubashkin′s appeal for a new trial.
