In 2010, Padilla v. Kentucky established that criminal defense lawyers must advise clients about the deportation consequences of a conviction, as part of their duties under the Sixth Amendment right to the effective assistance of counsel. Jose Padilla won in the Supreme Court because his trial lawyer erroneously informed him that he would not be deported after pleading guilty to drug trafficking because he had been in the U.S. for so long and had served in the military in Vietnam. However, Padilla’s case was remanded for a lower court determination of whether his trial lawyer’s incompetence caused him prejudice, since a defendant can win an ineffective assistance of counsel claim under the Court’s 1984 decision in Strickland v. Washington only by showing both attorney incompetence and prejudice.
Last week, in Lee v. United States, the Court considered the standard for proving prejudice, ruling in Lee’s favor in a 6-2 decision by Justice Roberts (Justices Alito and Thomas dissented). The Government conceded that Jae Lee’s trial lawyer failed to meet his duty under Padilla by assuring him that he would not be deported if he pled guilty to selling ecstasy. The only issue for the Court was the proper standard for proving prejudice when a defendant pleads guilty in a case involving strong evidence of guilt.
