Regaining Sovereignty? Brexit and the UK Parliament

Abstract

The flexible formula of the British Constitution results in a relative openness to external influences. Notwithstanding this fact, the United Kingdom’s (UK’s) membership in the European Union’s (EU’s) structures (1973–2020) resulted in a progressive limitation of the doctrine of parliamentary sovereignty. Brexit will not reverse the effects of the ‘soft’ modification of the foundations of the UK’s system, which occurred in the sphere of the practical implementation of the competencies of the branches of governance. Prima facie, the decision on the UK’s withdrawal from the EU should result in a ‘renaissance’ of the traditional doctrine of Westminster sovereignty, per A.V. Dicey. However, judicial activism, continued validity of the European Convention on Human Rights (incorporated on the basis of Human Rights Act 1998) and the irreversible consequences of the devolution of competencies in the UK for Wales, Scotland and Northern Ireland are the factors that hinder the possible revitalisation of the sovereignty of the British Parliament.
