International Law


The UK is subject to international law obligations and is a signatory to numerous international treaties and conventions, notably the European Convention on Human Rights. However, the mere fact that the UK Government accepts treaty obligations does not of itself have any effect on Parliamentary supremacy, as treaties are made by the Government and so do not change the law.

If the Government signs a treaty that requires a change in domestic law it is for Parliament to authorise such a change by legislation. In Blackburn v Attorney-General [1971] 2 All ER 1380 Lord Denning stated that "we take no notice of treaties until they are embodied in laws enacted by Parliament, and then only to the extent that Parliament tells us".
