United States v. Juarez, 672 F.3d 381 (5th Cir. Feb. 24, 2012) (reversing federal convictions of making a false claim to U.S. citizenship, in violation of 18 U.S.C. 911, and illegal reentry after deportation, in violation of 8 U.S.C. 1326(b)(2), on grounds of ineffective assistance of counsel for failure to investigate the facts, or research the law, concerning defendants derivative citizenship defense to the alienage element of these two offenses, since he failed to consult available research resources, including Kurzbans Immigration Law Sourcebook, which would have shown it to be a plausible defense which reasonably have motivated counsel to recommend against a guilty plea and defendant to decline to enter a guilty plea to these offenses, and thus the plea entered was not based on an informed or competent decision to do so).
