What this dot point is asking

Edexcel wants you to know the fundamental principles of law (the rule of law, the presumption of innocence, equality before the law and access to justice), that the UK contains different legal systems, and the main sources of law: common law and legislation. This Theme C topic (Paper 1 Section C) is tested through "Describe" tasks on principles such as the presumption of innocence and "Explain" tasks on the sources of law. The examiner rewards precise definitions of the principles, the distinction between common law and legislation, and the fact that England and Wales, Northern Ireland and Scotland have different legal systems.

The fundamental principles of law

These principles are what make a legal system fair rather than arbitrary. The rule of law means no one is above the law, including those in power, and that law is applied fairly and predictably. The presumption of innocence protects the accused: they are treated as innocent until proven guilty, and it is for the prosecution to prove the case beyond reasonable doubt, not for the accused to prove their innocence. Equality before the law means the same laws apply to everyone regardless of wealth or status. Access to justice means people can actually use the courts and legal help to enforce their rights, which is why issues such as legal aid matter. Edexcel often asks you to describe one of these principles precisely, so learn a clear definition of each.

This is an important and easily forgotten point. Because of history and devolution, the UK contains more than one legal system. England and Wales operate the same system, with the same courts and largely the same laws. Northern Ireland has its own legal system, and Scotland's is distinct, with some different rules, courts and legal traditions. This is why the specification refers to the justice system "in England and Wales" specifically. For citizenship, the key point is simply that the UK is not legally uniform, and that the detailed study of courts and the justice system in this theme focuses on England and Wales.

The sources of law

Law comes from two main places. Legislation is law made by Parliament in the form of Acts (statutes); it is written down, debated and passed through the law-making process, and it is the supreme source of law, so it can override other sources. Common law, also called case law or precedent, is developed by judges: when a court decides a case, its ruling can set a precedent that lower courts follow when deciding similar cases in future. Over time, judges' decisions build up a body of law on points that legislation does not cover. The crucial contrast Edexcel tests is that legislation is made by Parliament, while common law is developed by judges through precedent. Both shape the law that applies in everyday life.

Exam-style practice questions

Edexcel 20183 marksDescribe what is meant by the presumption of innocence.
Show worked answer →

A Paper 1 Section C "Describe" task (AO1). One mark per developed point, up to three.

The presumption of innocence means that a person accused of a crime is treated as innocent until they are proved guilty.

The burden of proof is on the prosecution, which must prove the case beyond reasonable doubt; the accused does not have to prove their innocence.

Markers reward the core idea of innocent until proven guilty, plus development such as the burden of proof being on the prosecution and the standard of proof.

Edexcel 20214 marksExplain the difference between common law and legislation as sources of law.
Show worked answer →

A Paper 1 "Explain" task (AO1 and AO2). Define each and contrast them.

Legislation is law made by Parliament in the form of Acts (statutes); it is written down and is the supreme source of law.

Common law (also called case law or precedent) is law developed by judges through their decisions in court cases; when judges decide a case, their ruling can set a precedent that lower courts follow in similar cases.

Markers reward the contrast: legislation is made by Parliament, while common law is developed by judges through precedent in their decisions.
