In Germany v. United States (2001), the International Court of Justice ruled that the Vienna Convention on Consular Relations confers judicially enforceable rights on foreign nationals detained for prolonged periods or sentenced to severe penalties without notice of their right to communicate with their consulates. The Court also ruled that states which fail to give timely notice cannot later invoke procedural default to bar individuals from judicial relief. However, the Court did not clearly address other issues, such as requiring individuals to show prejudice to the outcome of the trial, or denial of certain remedies for Convention violations, which may effectively foreclose relief.
