What is the final appeal court for human rights cases outside the EU?

The European Court of Human Rights (ECHR) serves as the final appeal court for human rights cases outside the European Union. It is an international court established by the European Convention on Human Rights, which aims to oversee and uphold the rights laid out in that Convention.

Individuals and states can bring cases before the ECHR if they believe their rights under the Convention have been violated. The court has the authority to interpret the Convention's provisions and can issue binding decisions on member states. As such, it plays a crucial role in interpreting human rights laws and ensuring their enforcement across its jurisdiction, making it the ultimate appeal body for cases involving human rights matters in signatory countries.

The other options represent domestic courts within specific countries. The Supreme Court, Court of Appeal, and High Court typically address a variety of legal matters, but they do not have the same mandate or jurisdiction regarding international human rights concerns as the ECHR does.
