In the United Kingdom, the courts can only apply directly
international treaties when when they are transformed into domestic law. In
practice, the United Kingdom has five forms of transforming international law
into domestic law: 1. Statutory law which does not mention treaties; 2. Statutory
law which mentions some provisions of treaties; 3. Statutory law being enacted
separately and having mentioned treaties in it; 4. Statutory law being enacted
separately relays the treaty and attaches the treaty as an annex; 5. Statutory law
clearly gives legal effect to international treaties. When applying international
treaties, the British courts distinguish between EU law and other international
treaties, and pay more attention to the interpretation method of the treaty itself.
