Unit 5: A Comparative Study of Constitutional Systems: The Great Britain and the United States of America
Table of Contents
Introduction to Comparative Constitutionalism
Comparative constitutionalism involves examining the constitutional frameworks of different nations to understand their unique features, underlying principles, and practical operation. This unit specifically focuses on a comparative study of the constitutional systems of the United Kingdom (Great Britain) and the United States of America. These two nations, despite sharing a common historical heritage, have evolved distinct and often contrasting constitutional arrangements, offering valuable insights into the diversity of governance models.
The Constitutional System of the United Kingdom (Great Britain)
The United Kingdom operates under a unique constitutional system that has developed organically over centuries. Unlike most modern states, it does not have a single codified document defining its fundamental laws.
Nature and Characteristics of the UK Constitution
- Unwritten/Uncodified: The UK constitution is not contained in a single document but is derived from various sources.
- Flexible: It can be amended by a simple Act of Parliament, making it highly adaptable to changing circumstances. There is no special procedure required for constitutional amendments.
- Unitary: Power is centralized at the national level, specifically in the Parliament at Westminster. While devolution has granted powers to Scotland, Wales, and Northern Ireland, ultimate legal sovereignty remains with the UK Parliament.
- Parliamentary Sovereignty: Parliament is the supreme legal authority. It can make or unmake any law, and no other body (including the courts) can challenge its legislative power.
- Monarchical: A constitutional monarchy where the monarch (King/Queen) is the head of state, but their powers are largely ceremonial and exercised on the advice of elected ministers.
Key Institutions of the UK Government
The UK government is characterized by a fusion of powers, particularly between the executive and legislative branches.
- The Monarchy: The King or Queen serves as the Head of State, embodying national identity and continuity. Powers include appointing the Prime Minister, assenting to legislation, and commanding the armed forces, but these are almost always exercised on the advice of the government.
- Parliament: The supreme legislative body, comprising:
- House of Commons: The democratically elected chamber, consisting of Members of Parliament (MPs). It holds primary legislative power, controls public finances, and scrutinizes the executive.
- House of Lords: The unelected upper chamber, primarily composed of life peers, hereditary peers, and bishops. Its roles include scrutinizing legislation, proposing amendments, and debating important issues. Its power to block legislation passed by the Commons is limited.
- The Executive: Comprises the Prime Minister and the Cabinet.
- Prime Minister: The Head of Government, typically the leader of the party with a majority in the House of Commons. Appointed by the monarch, the PM leads the Cabinet and directs government policy.
- Cabinet: Senior ministers chosen by the Prime Minister, responsible for specific government departments. They are collectively responsible to Parliament.
- The Judiciary: Interprets and applies the law. The Supreme Court of the United Kingdom is the highest court of appeal. While independent, the judiciary cannot strike down Acts of Parliament due to parliamentary sovereignty.
Core Principles of the UK Constitution
- Parliamentary Sovereignty:
Parliament has the right to make or unmake any law whatever; and, further, that no body is recognised by the law of England as having a right to override or set aside the legislation of Parliament. - A.V. Dicey
This principle means that Parliament can legislate on any matter, and its laws cannot be challenged by the courts. - Rule of Law: Everyone, including those in power, is subject to and accountable under the law. It ensures legal certainty, equality before the law, and that power is exercised according to established legal rules.
- Fusion of Powers: There is a significant overlap between the executive and legislative branches. Members of the executive (Prime Minister and Cabinet) are also members of Parliament. This contrasts with a strict separation of powers.
- Constitutional Monarchy: The monarch reigns but does not rule; political power rests with the elected Parliament and government.
Sources and Evolution of the UK Constitution
The UK constitution is a dynamic entity that has evolved through various sources:
- Statutes (Acts of Parliament): Major laws passed by Parliament that have constitutional significance (e.g., Magna Carta 1215, Bill of Rights 1689, Act of Settlement 1701, Human Rights Act 1998).
- Common Law: Judge-made law developed through judicial precedents over centuries.
- Conventions: Unwritten rules and practices that govern the conduct of political actors, though not legally enforceable (e.g., the monarch assents to all bills, the Prime Minister is the leader of the majority party).
- Authoritative Works: Writings of constitutional experts (e.g., A.V. Dicey's Introduction to the Study of the Law of the Constitution) inform constitutional understanding.
- Treaties and International Law: International agreements, particularly those related to the European Union (though the UK has left) and the European Convention on Human Rights, have influenced UK law.
The Constitutional System of the United States of America
The United States of America operates under a written, codified constitution that establishes a federal republic with a strong emphasis on the separation of powers and checks and balances.
Nature and Characteristics of the US Constitution
- Written/Codified: The US Constitution is a single, supreme legal document, adopted in 1787 and effective in 1789. It is the supreme law of the land.
- Rigid: It is difficult to amend, requiring a supermajority (two-thirds vote in both houses of Congress and ratification by three-fourths of the states). This rigidity ensures stability but can make adaptation challenging.
- Federal: Power is divided between a national (federal) government and individual state governments. Both derive their authority from the Constitution.
- Presidential: Features a strong, separately elected executive (the President) who is both Head of State and Head of Government.
- Republican: A system of government in which the people hold popular sovereignty, but elected representatives exercise political power.
Key Institutions of the US Government
The US government is structured around a strict separation of powers to prevent the concentration of authority.
- The Executive Branch: Headed by the President.
- President: Elected independently of the legislature for a fixed four-year term. Serves as Commander-in-Chief, chief diplomat, and administrator of the federal government. The President appoints cabinet members (Secretaries of departments) who are not members of Congress.
- The Legislative Branch (Congress): A bicameral legislature.
- House of Representatives: Members are elected for two-year terms, with representation based on state population. Initiates revenue bills and has the power to impeach federal officials.
- Senate: Two senators from each state, elected for six-year terms. Confirms presidential appointments, ratifies treaties, and tries impeachment cases.
- The Judicial Branch: Interprets the Constitution and federal laws.
- Supreme Court: The highest court in the federal judiciary, consisting of nine justices appointed for life by the President with Senate confirmation. Exercises the power of judicial review.
- Lower Federal Courts: District courts and Courts of Appeals.
Core Principles of the US Constitution
- Separation of Powers: Governmental powers are divided among three distinct branches (legislative, executive, judicial) to prevent tyranny and ensure accountability.
- Checks and Balances: Each branch has specific powers to limit or check the powers of the other two branches, ensuring no single branch becomes too powerful (e.g., presidential veto, Senate confirmation of appointments, judicial review).
- Federalism: The division of powers between the national government and state governments, with both exercising powers directly over individuals.
- Judicial Review: The power of the courts, especially the Supreme Court, to determine whether acts of the legislative and executive branches are consistent with the Constitution. Established in Marbury v. Madison (1803).
- Popular Sovereignty: The idea that the ultimate authority of government resides in the people, who delegate their power to elected representatives.
- Limited Government: The government's powers are restricted and defined by the Constitution to protect individual liberties.
Amendments to the US Constitution
The US Constitution has been amended 27 times. The first ten amendments are known as the Bill of Rights, guaranteeing fundamental individual freedoms.
Amendment Process (Article V):
- Proposal:
- By a two-thirds vote of both the House of Representatives and the Senate, OR
- By a national convention called for by two-thirds of the state legislatures (never used).
- Ratification:
- By three-fourths of the state legislatures, OR
- By three-fourths of special state conventions (used only once for the 21st Amendment).
The difficulty of amendment reflects the US Constitution's rigidity and the founders' desire for a stable fundamental law.
Comparative Analysis: UK vs. USA
Comparing the UK and US constitutional systems reveals fundamental differences in their structure, principles, and operation. These differences stem from distinct historical developments and philosophical underpinnings.
Written vs. Unwritten Constitution
| Feature | United Kingdom | United States of America |
|---|---|---|
| Nature | Unwritten/Uncodified (composed of various statutes, common law, conventions). | Written/Codified (single document adopted in 1787). |
| Clarity | Less clear-cut, relies on historical practice and interpretation. | Clearer foundational document, though subject to judicial interpretation. |
| Flexibility | Flexible; can be amended by simple Act of Parliament. | Rigid; requires supermajorities for amendment (Article V). |
| Supremacy | Parliamentary sovereignty; no law is superior to an Act of Parliament. | Constitutional supremacy; the Constitution is the supreme law of the land. |
Unitary vs. Federal System
| Feature | United Kingdom | United States of America |
|---|---|---|
| Structure | Unitary; power is centralized in the Westminster Parliament. | Federal; power is divided between the national (federal) government and state governments. |
| Devolution/States | Devolution of power to Scotland, Wales, N. Ireland, but Parliament retains ultimate sovereignty. | States retain significant powers not delegated to the federal government or prohibited to them. |
| Law Making | Uniform laws generally apply across the UK, though devolved bodies can make laws on specific matters. | Federal laws apply nationally; state laws vary significantly from state to state. |
Parliamentary vs. Presidential System
| Feature | United Kingdom (Parliamentary) | United States of America (Presidential) |
|---|---|---|
| Head of Government | Prime Minister (leader of the majority party in Parliament). | President (directly elected by the people via Electoral College). |
| Head of State | Monarch (ceremonial). | President (both Head of State and Head of Government). |
| Executive & Legislature | Fusion of powers; PM and Cabinet are members of Parliament and accountable to it. | Strict separation of powers; President and Cabinet are not members of Congress and are not directly accountable to it. |
| Accountability | Executive depends on the confidence of Parliament; government can fall on a vote of no confidence. | Executive serves for a fixed term; impeachment is the primary means of removal. |
| Elections | General elections determine the composition of Parliament; the PM is usually the leader of the winning party. | Presidential elections are separate from legislative (Congressional) elections. |
Nature of Sovereignty
| Feature | United Kingdom | United States of America |
|---|---|---|
| Ultimate Authority | Parliamentary Sovereignty; Parliament is the supreme legal authority. | Popular/Constitutional Sovereignty; the people are sovereign, and the Constitution is the supreme law. |
| Limits on Power | Few legal limits on Parliament's power (primarily political/conventional). | Government power is limited by the Constitution and the Bill of Rights. |
Separation of Powers
| Feature | United Kingdom | United States of America |
|---|---|---|
| Principle | Fusion of powers (especially executive and legislative). | Strict separation of powers (Legislative, Executive, Judicial). |
| Overlap | Ministers sit in Parliament; judiciary is independent but limited by parliamentary sovereignty. | Distinct personnel for each branch; system of checks and balances. |
Role of the Judiciary and Judicial Review
| Feature | United Kingdom | United States of America |

| Supreme Court | Established in 2009; highest court of appeal. | Established by Article III of the Constitution; highest court. |
Protection of Rights
| Feature | United Kingdom | United States of America |
|---|---|---|
| Source of Rights | Derived from common law, statutes (e.g., Human Rights Act 1998 incorporating ECHR), and conventions. | Entrenched in the Bill of Rights (first 10 amendments) and subsequent amendments to the Constitution. |
| Enforcement | Parliament can legislate to limit or extend rights; HRA allows courts to declare laws incompatible with ECHR, but Parliament is not bound to change them. | Judiciary (especially Supreme Court) actively protects constitutional rights through judicial review; laws violating the Bill of Rights can be struck down. |
Conclusion
The constitutional systems of the United Kingdom and the United States, while both democracies, represent fundamentally different approaches to governance. The UK's unwritten, flexible, unitary, and parliamentary system built on parliamentary sovereignty contrasts sharply with the USA's written, rigid, federal, and presidential system founded on constitutional supremacy and strict separation of powers. Understanding these distinctions is crucial for appreciating the diverse paths nations take in structuring their political authority, protecting rights, and ensuring accountability within a democratic framework. This comparative study highlights that while the goals of good governance may be universal, the mechanisms to achieve them can vary significantly.
