Sovereignty is one of the fundamental concepts in international law. It is an integral part of the principles of equality of States, territorial integrity and political independence that are referred to in Article 2 of the United Nations Charter. Sovereignty is crucial to the exercise of powers by a State over both its territory and the people living in that territory. This chapter discusses traditional means of acquisition of territory; effective occupation; consent by other States; and limitations on sovereignty over territory.

Celebrated for their conceptual clarity, titles in the Clarendon Law Series offer concise, accessible overviews of major fields of law and legal thought. This chapter considers two principal sources of doubt concerning the legal character of international law and, with them, the steps which theorists have taken to meet these doubts. Both forms of doubt arise from an adverse comparison of international law with municipal law, which is taken as the clear, standard example of what law is. The first has its roots deep in the conception of law as fundamentally a matter of orders backed by threats and contrasts the character of the rules of international law with those of municipal law. The second form of doubt springs from the obscure belief that states are fundamentally incapable of being the subjects of legal obligation, and contrasts the character of the subjects of international law with those of municipal law.

This chapter examines the characteristics of the UK constitution. The main features of the UK constitution are that it is uncodified; flexible; traditionally unitary but now debatably a union state; monarchical; parliamentary; and based on a bedrock of important constitutional doctrines and principles: parliamentary sovereignty, the rule of law, separation of powers; the courts are also basing some decisions on bedrock principles of the common law. Meanwhile, the laws, rules, and practices of the UK constitution can be found in constitutional statutes; judicial decisions; constitutional conventions; international treaties; the royal prerogative; the law and custom of Parliament; and works of authoritative writers. The chapter then looks at the arguments for and against codifying the UK constitution.

This chapter explains the process and significance of the UK’s membership in the EU and sets out the authorities underpinning the supremacy of EU law, accepted and established prior to the UK’s accession. It then explores cases—from the early 1970s to the present day—which consider the ways in which EU membership has impacted on Parliament’s sovereignty. Following this, the chapter explores the legal and political landscape of the UK’s departure from the EU. It considers the process through which Brexit is happening and the manner in which the constitution will provide the foundation for a working relationship with the EU in the future and establish a stable legal system in the UK post-Brexit, looking particularly at the European Union (Withdrawal) Act 2018 and the European Union (Withdrawal Agreement) Act 2020.

This chapter is, for obvious reasons, not a modification of the chapter from the previous edition. It is a completely new chapter, which considers the effect of Brexit on the UK constitution. There is discussion of the constitutional implications of triggering exit from the EU, and whether this could be done by the executive via the prerogative, or whether this was conditional on prior legislative approval through a statute. The discussion thereafter considers the constitutional implications of Brexit in terms of supremacy, rights, executive accountability to the legislature and devolution. The chapter concludes with discussion as to the paradox of sovereignty in the context of Brexit.

Each Concentrate revision guide is packed with essential information, key cases, revision tips, exam Q&As, and more. Concentrates show you what to expect in a law exam, what examiners are looking for, and how to achieve extra marks. This chapter discusses the definition of constitutional law and the characteristics of the British Constitution. Constitutional law looks at a body of legal rules and political arrangements concerning the government of a country. A constitution may take the form of a document or set of documents which declare that a country and its chosen form of government legitimately exists. The British Constitution is largely unwritten, flexible in nature, and based on absolute parliamentary sovereignty. The UK is also a unitary state. There is a central government, as well as devolved legislative and executive bodies in Scotland, Wales, Northern Ireland, and England. It is also a constitutional monarchy. This means that the head of state is a king or queen and that they exercise their powers in and through a parliamentary system of government in which the members of the executive are accountable to a sovereign parliament.

Essential Cases: Public Law provides a bridge between course textbooks and key case judgments. This case document summarizes the facts and decision in Case of Proclamations [1610] 77 ER 1352 12 Co Rep 74, King’s Bench. This classic public law case concerned whether the King could rule by proclamation, or whether he was required to rule through Parliament. It provides one of the core foundations of the law limiting the scope of the royal prerogative today. The document also includes supporting commentary and questions from author Thomas Webb.

This chapter explores the principle of parliamentary sovereignty. It defines the theory in orthodox terms set out by Dicey and explains the manner in which it has developed out of the Bill of Rights and on the back of the unsettled constitutional times that prevailed during the seventeenth century. It then sets out the legal basis for sovereignty, calling on the authority of Wade, Jennings, and Goldsworthy to explain the importance of the courts’ role in determining and providing the foundation for Parliament’s authority. Next, it explores the fundamental aspects of the orthodox theory, explaining how that operates in practice and discussing the various challenges and limitations that have arisen since the late nineteenth century. The chapter concludes by considering the position of parliamentary sovereignty today, analysing the extent to which orthodox Diceyan theory can be said still to be relevant.

This chapter focuses on the State as the primary subject of international law. It begins with a discussion of the continuing pre-eminence of States as pivotal subjects of the international legal system and then analyses the processes through which States are created; the role of recognition of States, particularly in the context of contested Statehood; the legal rules governing the continuity, succession, and extinction of States; and the evolving concept of sovereignty, which is a notion at the very core of what a State is. The chapter is intended to introduce the main legal aspects of ‘Statehood’, as a first step in the discussion of more advanced concepts in subsequent chapters, such as the State’s spatial dimensions, its immunities and those of State officials, and the many limitations imposed by international law on State action.

This chapter examines the way in which the UK’s membership in the European Economic Community (EEC) prompted changes in the domestic constitutional order. The discussions include the founding principles of the Treaty of Rome; the accession of the UK into the EEC; EEC law, parliamentary sovereignty, and the UK courts; and the horizontal and vertical effects of directives. The chapter explores the controversies engendered by the Maastricht, Amsterdam, and Lisbon Treaties; and concludes by assessing in what senses continued EC membership in the early part of the twenty-first century might have entailed a loss of the UK’s ‘sovereignty’ to a federal European constitution and a rebalancing of power within the domestic constitution between Parliament and the courts.

This chapter considers the European Convention on Human Rights (ECHR) and its relationship to the English legal system. The focus in the chapter is on key provisions of the Human Rights Act 1998—the Act that incorporated the Convention into UK law. In the earlier part of the chapter there is coverage of sections 2, 3, and 4 of the Act. These provisions concern the duties placed on the courts to take into account judgments of the European Court of Human Rights, to interpret domestic legislation so as to comply with rights under the Convention, and finally to issue a declaration of incompatibility when domestic legislation does not comply with rights under the Convention. Using examples from the case law, the chapter assesses how the courts balance their constitutional role to respect the supremacy of Parliament, with the duties provided in the Act to respect rights under the Convention. There is also an analysis of s.6 of the Human Rights Act 1998 which makes it unlawful for a public authority to act incompatibly with Convention rights. The analysis includes the contested question of what precisely constitutes a ‘public authority’, particularly when a private body is carrying out a public function.

This chapter begins by defining international economic law. It then discusses the main international economic institutions: the World Trade Organization, the International Monetary Fund and the World Bank. It goes on to elaborate on the key principles of international trade law: tariffication, binding tariffs, most favoured nation treatment and the national treatment obligation and discusses exceptions to these principles, anti-dumping and subsidies, regional trade arrangements, and developing States and dispute settlement within the WTO. The chapter also discusses the key principles of international investment law (including foreign direct investment, protection standards, expropriation and dispute settlement); the international financial architecture; and international economic law and State sovereignty.
Chapter
The interaction between international law and domestic (or national or ‘municipal’) law demonstrates the struggle between State sovereignty and the international legal order. While the international legal order seeks to organise international society in accordance with the general interests of the international community, State sovereignty can be used to protect a State against the intervention of international law into its national legal system. This chapter discusses theories about the relations between international law and national law; national law on the international plane; international law on the national plane; and examples of international law on the national plane.

Celebrated for their conceptual clarity, titles in the Clarendon Law Series offer concise, accessible overviews of major fields of law and legal thought. The doctrine of sovereignty asserts that in every human society, where there is law, there is ultimately to be found latent beneath the variety of political forms this simple relationship between subjects rendering habitual obedience and a sovereign who renders habitual obedience to no one. This vertical structure composed of sovereign and subjects is, according to the theory, as essential a part of a society which possesses law, as a backbone is of a man. This chapter considers two important points in this doctrine. The first concerns the idea of a habit of obedience, which is all that is required on the part of those to whom the sovereign's laws apply. The chapter examines whether such a habit is sufficient to account for two salient features of most legal systems: the continuity of the authority to make law possessed by a succession of different legislators, and the persistence of laws long after their maker and those who rendered him habitual obedience have perished. The second point concerns the position occupied by the sovereign above the law: he creates law for others and so imposes legal duties or ‘limitations’ upon them whereas he is said himself to be legally unlimited and illimitable. The chapter inquires whether this legally illimitable status of the supreme lawgiver is necessary for the existence of law, and whether either the presence or the absence of legal limits on legislative power can be understood in the simple terms of habit and obedience into which this theory analyses these notions.
