The Law
1. One country, three legal systems
The UK does not have one unified legal system:
•
England & Wales – Common law system
•
Scotland – Mixed system (civil law + common law)
•
Northern Ireland – Common law (similar to England)
Each has its own courts and legal traditions.
2. Common law: the core idea
In England & Wales, law developed through:
•
Judicial decisions (case law)
•
Precedent (stare decisis — courts follow earlier rulings)
•
Statute law passed by Parliament
Judges do not just apply law; they interpret and shape it.
3. Sources of British law
A. Statute law
•
Laws passed by Parliament
•
Supreme legal authority

Example: Magna Carta (1215), Human Rights Act 1998
B. Common law
•
Law developed by judges over centuries
•
Covers contract, tort, property, crime
C. Equity
•
Developed by the Court of Chancery
•
Focuses on fairness where common law was too rigid
•
Trusts, injunctions, fiduciary duties
D. European & international law
•
EU law influenced UK law until Brexit
•
Some retained EU law remains
•
International treaties influence domestic law when enacted

Rule of law

Parliament is the supreme law-making body
•
Courts interpret, not overturn, Acts of Parliament
Judicial independence
•
Courts are free from political control
7. No written constitution
Unlike many countries, the UK has no single constitutional document. Instead, it relies on:
•
Statutes (e.g. Bill of Rights 1689)
•
Common law principles
•
Constitutional conventions
•
Authoritative works (e.g. Dicey)
8. Historical roots
•
Anglo-Saxon law – local customs
•
Norman reforms – royal courts, uniform law
•
Magna Carta (1215) – limits on royal power
•
18th–19th centuries – modern court system
9. Why it matters globally
British common law influenced:
•
The USA
•
Canada
•
Australia
•
India
Concepts like precedent and judicial review spread worldwide
Bill of Rights 1689
The Bill of Rights 1689 is one of the most important
constitutional documents in British history. It permanently
limited the power of the monarchy and laid the foundations for
constitutional monarchy, parliamentary sovereignty and civil
liberties.
The Bill of Rights emerged from the Glorious Revolution
(1688):
•
James II (Catholic) was accused of ruling arbitrarily
and ignoring Parliament.
•
He was deposed and replaced by William III and Mary
II.
•
Parliament offered them the crown on condition they
accept a Declaration of Right, which was later enacted
as the Bill of Rights 1689.
This settled a long struggle between Crown and Parliament.
Key principles established
1. Limited royal power
2. Strengthened Parliament
3. Protected individual rights
4. Secured the Protestant succession
•
Rule of law – the monarch governs according to law
•
Parliamentary sovereignty – Parliament is supreme
•
Constitutional monarchy – the monarch reigns but
does not rule
