Such an interpretation of the case is supported by statements in "Thoburn v Sunderland City Council" and "Hunt v Hackney Borough Council" to the effect that there now exist two forms of Acts of Parliament: ordinary acts which can be repealed impliedly, and "statutory" or "constitutional" acts which can only be repealed expressly. (See in particular the judgment of Laws LJ in "Thoburn".) Nevertheless, there is no restriction on the ability of Parliament to expressly repeal the European Communities Act 1972.
