Majority (Kagan) - "In Padilla v. Kentucky, 559 U. S. ___ (2010), this Court held that the Sixth Amendment requires an attorney for a criminal defendant to provide advice about the risk of deportation arising from a guilty plea. We consider here whether that ruling applies retroactively, so that a person whose conviction became final before we decided Padilla can benefit from it. We conclude that, under the principles set out in Teague v. Lane, 489 U. S. 288 (1989), Padilla does not have retroactive effect."
Dissent (JUSTICE SOTOMAYOR, with whom JUSTICE GINSBURG joins) - "The Court holds today that Padilla v. Kentucky, 559 U. S. ___ (2010), announced a “new” rule within the meaning of Teague v. Lane, 489 U. S. 288, 301 (1989), and so does not apply to convictions that became final before its announcement. That is wrong, because Padilla did nothing more than apply the existing rule of Strickland v. Washington, 466 U. S. 668 (1984), in a new setting, the same way the Court has done repeatedly in the past: by surveying the relevant professional norms and concluding that they unequivocally required attorneys to provide advice about the immigration consequences of a guilty plea. Because Padilla fell squarely within the metes and bounds established by Strickland, I respectfully dissent."
