Since the judgment in Thoburn, Parliament itself has recognised a class of statutory provisions which are of ‘constitutional significance’. There is certainly, now, a distinction in law between constitutional and ordinary
statutory provisions. While this does not ‘entrench’ constitutional provisions from the ordinary legislative process, there are other good reasons why this distinction should be made. Thus, it is possible, indeed desirable, to distinguish between ordinary and constitutional provisions without necessarily posing any threat to parliamentary sovereignty.
