In 2006, the United States Supreme Court ruled that foreign nationals who were not notified of their right to consular notification and access after an arrest may not use the treaty violation to suppress evidence obtained in police interrogation or belatedly raise legal challenges after trial ("Sanchez-Llamas v. Oregon"). In 2008, the U.S. Supreme Court further ruled that the decision of the ICJ directing the United States to give "review and reconsideration" to the cases of 51 Mexican convicts on death row was not a binding domestic law and therefore could not be used to overcome state procedural default rules that barred further post-conviction challenges ("Medellín v. Texas").
