Decisions of the International Court of Human Rights are enforceable through the domestic courts in the country from which the case arises. Failure of any government to comply with the decisions of the Court may result in expulsion from the International Bill of Rights treaty following a vote of two thirds of the Judges of the Court.
Part of the beauty of IBOR is that it becomes part of the fabric of everyday life over time. For example, with time, all people on Earth will be able to speak freely about government officials without fear of government punishment.
Along this path, as in all human endeavors, there will be disagreements, but the rule of law provides benefits to those who follow it. Should a country fail to follow the interpretation of courts, flexibility rather than alienation should be the hallmark. But if core principles are not followed, then the judges, beholden to the document and not the country that appointed them, may vote to expel a nation from participation in. IBOR.
