  Constitutions will also vary on the extent to which human rights recognised under international law or treaty are recognised in national law. For example, in some countries in Europe, the European Convention on Human Rights, and decisions of the European Court of Human Rights thereon, are incorporated into national law and override any national law inconsistent with them. In others, such as the United Kingdom, the courts have, so far as possible, to interpret legislation to be consistent with the Convention, but have no power to strike it down even if they find it to be clearly inconsistent.
