My thesis deals with the legal concept of sovereign Parliament, the very keystone of British constitution according to A. V. Dicey. This model has been challenged both normatively and descriptively. Concerning the normative point of view, concept of unlimited sovereignty is incoherent. Descriptively, courts don't simply take the parliamentary supremacy for granted, even if they say so. Relationship between the Parliament and courts is certainly more complex than Dicey suggested. Goals of this thesis are rather tentative. Since the popularity of this topic among British constitutional lawyers, comprehensive analysis is implausible due to the limited space. This paper aims to gather fundamental theories and disputes regarding the parliamentary sovereignty and its relationship with courts. In other words, it explores connection between the Parliament and courts in contemporary British constitution. First chapter analyses the constitutional conventions, which forms the basics of several other fundamental concepts in UK constitution. It suggests that there are no clear boundaries between law and conventions. Second chapter focuses on the general concept of sovereignty and Diceyan classic theory of Parliamentary sovereignty. There is also a brief explanation of sovereignty's connection to Scot's law....

C’est à tort qu’on a considéré que l’ordre juridique anglais ne connaît ou ne pourrait connaître un contrôle de la «loi». Si l’on y a vu une irréductible doctrine de la souveraineté du parlement, qui met en place un «règne de la légalité» froid et implacable, l’on a, en cela, méconnu le véritable sens de la common law, comme porteur d'une unique idée de «jurisdictio» à travers les temps, déployant un programme de droit tant herméneutique que fondamentalement constitutionnaliste, tout en étant en perpétuel devenir. La doctrine de la souveraineté du parlement tire sa reconnaissance d’une doctrine common law. Or, la «légalité», par ses postulats même, est prise au piège par un deuxième principe qui en émane, celui que nous nommons «principe de supra-légalité», du fait du contenu même de certains Actes du Parlement et de la considération que leur réserve la common law. Par ailleurs, la common law est celle qui a permis en sa «jurisdictio», la «Rule of Law», et par là, de s’assurer d'une «constitution common law». De son fait jurisprudentiel, comme dialectique et discours, elle vise une mise en œuvre perpétuelle en problématique permanente de toute norme supérieure. C'est ce qui caractérise le «principe de jurisprudentialité» qui s’ajoute ainsi à la «supra-légalité». Principes de légalité, de supra-légalité et de jurisprudentialité sont ceux qui façonnent alors le principe de constitutionnalité en cette constitution common law. La common law, seul gardien des principes intangibles du droit, autonome et auto-validée par sa Raison fut le premier modèle constitutionnaliste existant dans les droits modernes. / It has been one of the main legal misunderstandings of the modern world that the English legal system cannot admit of anyconstitutional review of laws. The prevailing idea colouring any vision ofits constituent parts has been marked by a cold anrlirreducible doctrine of the Sovereignty of Parliament which in turn has brought about a <Rule of Legality> narrowly definerl - far from being akin to any Diceyean <<Rule of Lawr (or Rule of (the' Law)- , thereby preventing any constitutionalist territory within its domain to be carved orrt. This half-truth has masked the real meaning of the common law, as spelling out over centuries, a unique idea of <jurisdictio>, underlying which is a programme polarized by a hermeneutic vision of itself as law-realisation, as well as being a constitutionalist backdrop to any legal system. The doctrine of the Sovereignty of Parliament derives its recognition from what can be termed as the <Principle of Jurisprudentiality>, the keystone of the <Common Law Constitution>>. Legality, in turn, hy its fundamentals, is caught in its own game, by an emerging superior principle, that of what is here termed <Supra-Legality>, if only owing to the content of Acts of Parliament themselves. The Common Law, the only guardian of intangible or immutable principles of law, autonomous and self-validating due to its Reason, did bring about a first constitutionalist model in the modern world. At all times, a constitutional review of laws has been carried out in the English legal system, albeit under different guises, now enhanced following the incorporation of the ECHR and community laws.
