Law Making: Judicial Precedent (AQA A-Level Law 7162 — Paper 1)
Welcome to your complete study guide for Judicial Precedent! This topic is tested in Section A of Paper 1 (worth \(25\) marks across multiple-choice, short-answer, and \(15\)-mark evaluation questions). Don't worry if legal Latin and court hierarchies seem intimidating at first — by breaking down each concept step by step, you will master the mechanics, cases, and evaluations needed for top marks.
---1. Foundations of the Doctrine
The English legal system is a common law system. This means that law is not only made by Parliament through statutes, but also by judges through decisions made in court cases.
What is Stare Decisis?
The entire system of precedent rests on the Latin principle: stare decisis et non quieta movere, which translates to: "to stand by things decided and not disturb settled points."
In simple terms: like cases must be decided alike. When a point of law is decided in a higher court, lower courts in the same hierarchy must follow that rule in future cases with similar facts.
The Anatomy of a Judgment: Ratio vs Obiter
When a judge delivers a judgment at the end of a trial or appeal, the speech is divided into two distinct parts:
1. Ratio Decidendi ("The reason for the decision"):
• This is the vital legal principle upon which the final outcome of the case depends (defined by legal scholar Sir Rupert Cross).
• Crucial rule: The ratio decidendi is the only part of the judgment that creates binding precedent for future judges.
2. Obiter Dicta ("Things said by the way"):
• These are additional comments, hypothetical examples, or discussions of legal theories not strictly necessary to decide the case.
• It also includes dissenting judgments given by judges who disagree with the majority.
• Crucial rule: Obiter dicta statements are never binding; they only act as persuasive precedent.
Everyday Analogy: Imagine your school sets a rule: "Students arriving after 8:30 AM without a medical note receive a detention" (this is the ratio — the binding rule). The headteacher adds: "And if it were snowing, we might consider relaxing this" (this is obiter — a helpful passing remark, but not part of today's actual decision).
The Role of Law Reporting
For precedent to work, lawyers and judges must be able to read past judgments. Systematic law reporting records the facts, legal arguments, and exact ratio decidendi of cases.
• In 1865, the Incorporated Council of Law Reporting was established to produce the Official Law Reports.
• Other recognized reports include the All England Law Reports (All ER) and modern online databases such as LexisNexis, Westlaw, and BAILII.
Key Takeaway: Only the ratio decidendi (reason for the decision) creates binding law; obiter dicta (things said by the way) provides non-binding guidance.
---2. The Three Types of Precedent
Judicial precedents fall into three core categories:
A. Original Precedent
Occurs when a court faces a completely novel point of law with no existing statute or prior case law to guide it. The judge must create a brand-new rule of law.
• Key Example: Donoghue v Stevenson [1932] — The House of Lords created the "neighbour principle" in negligence after a consumer found a decomposed snail in an opaque ginger beer bottle.
• Key Example: Hunter v Canary Wharf [1997] — Dealing with whether interference with television reception could amount to a legal nuisance.
B. Binding Precedent
A rule of law decided in an earlier case by a higher court (or sometimes equal court) that a later judge must follow, provided the material facts of the current case are sufficiently similar.
C. Persuasive Precedent
A legal statement that is not binding on a court, but which a judge may consider, find convincing, and choose to follow. There are five recognized sources of persuasive precedent:
1. Decisions of Lower Courts:
• Higher courts can adopt reasoning from lower courts.
• Authority: In R v R [1991], the House of Lords followed and approved the decision of the Court of Appeal to abolish the marital rape exemption.
2. Dissenting Judgments:
• When an appellate bench disagrees, the minority judge delivers a dissent. Future courts can later adopt that minority view.
• Authority: Lord Denning's dissenting judgment in Candler v Crane, Christmas & Co [1951] was later approved and adopted by the House of Lords in Hedley Byrne v Heller [1964] (regarding negligent misstatement).
3. Obiter Dicta Statements:
• Speculative remarks made in an earlier case can be adopted as binding law in a later case.
• Authority: In R v Howe [1987], the House of Lords stated obiter that duress should not be a defence to attempted murder. In R v Gotts [1992], the Court of Appeal chose to follow that obiter remark and made it binding law.
4. Decisions of Courts in Other Common-Law Jurisdictions:
• Decisions from countries with similar common-law roots (such as the USA, Canada, or Australia) can persuade English courts.
• Authority: Re S [1992] (where the court considered decisions from US authorities regarding forced caesarean sections).
5. Decisions of the Judicial Committee of the Privy Council (JCPC):
• The JCPC is the appeal court for certain Commonwealth nations. While its rulings do not strictly bind English courts, its bench consists of UK Supreme Court Justices, giving its decisions immense persuasive weight.
• Authority: The Wagon Mound No. 1 [1961] (remoteness of damage in tort) and Attorney-General for Jersey v Holley [2005] (loss of control/provocation defence).
Key Takeaway: Precedent can be Original (inventing a new rule), Binding (must be followed), or Persuasive (optional, originating from lower courts, dissents, obiter, foreign common-law courts, or the Privy Council).
---3. Court Hierarchy and Binding Authority
To understand what binds whom, we look at the appellate hierarchy from top to bottom:
1. The UK Supreme Court (formerly the House of Lords)
• Hierarchy: The highest domestic court. Its decisions bind all lower courts in England and Wales.
• Past Rule: In London Tramways Co v London County Council [1898], the House of Lords decided that it was strictly bound by its own past decisions to maintain total certainty.
• The Turning Point — The Practice Statement 1966: Lord Gardiner LC issued a formal declaration allowing the House of Lords (and now the Supreme Court via Austin v London Borough of Southwark [2010]) to depart from its own past decisions "when it appears right to do so" to prevent injustice and undue restriction on the proper development of the law.
Major Applications of the Practice Statement:
• First Civil Use: British Railways Board v Herrington [1972] — departed from Addie v Dumbreck [1929] to impose a duty of common humanity toward child trespassers due to changing social conditions.
• First Major Criminal Use: R v Shivpuri [1986] — overruled Anderton v Ryan [1985] on attempting the impossible under the Criminal Attempts Act 1981, recognising that the earlier decision had misapplied the statute.
• Other Notable Uses:
— R v R [1991]: Overruled centuries of outmoded common law to confirm that a husband can be convicted of raping his wife.
— R v Jogee [2016]: Corrected the law on joint enterprise (parasitic accessorial liability) by overruling the rules derived from Chan Wing-Siu and Powell and English.
2. The Court of Appeal
The Court of Appeal is bound by the UK Supreme Court and binds all inferior courts below it. It is split into two divisions:
A. The Civil Division
Generally bound by its own past decisions, subject strictly to the three exceptions established in Young v Bristol Aeroplane Co Ltd [1944]:
1. Conflicting Decisions: Where two previous Court of Appeal decisions clash, the court must choose which one to follow and which to reject.
2. Inconsistency with Higher Authority: Where a previous Court of Appeal decision is expressly or implicitly overruled by a subsequent Supreme Court (House of Lords) decision.
3. Per Incuriam ("through lack of care"): Where a previous decision was reached in ignorance or forgetfulness of an applicable statute or a binding Supreme Court precedent.
B. The Criminal Division
The Criminal Division applies the three Young exceptions, but also has an additional flexibility power under R v Gould [1968] and R v Spencer [1985]:
• It can depart from its own past decision if the law was misapplied or misunderstood, because in criminal matters, an individual's personal liberty is at stake.
3. The High Court and Inferior Courts
• High Court Divisional Courts (King's Bench, Chancery, Family) are bound by the Supreme Court and Court of Appeal, and bind lower courts.
• High Court judges sitting alone at first instance: Bind inferior courts. They are not strictly bound by other High Court judges, though they follow them for consistency as persuasive authority unless convinced the decision was wrong.
• Inferior Courts (Crown Court, County Court, Magistrates' Court): Bound by all higher courts. They cannot create binding precedents, and their judgments are not systematically reported.
Key Takeaway: The Supreme Court can depart from its own past decisions using the Practice Statement 1966. The Court of Appeal Civil Division is bound by its own decisions unless one of the three Young v Bristol Aeroplane exceptions applies; its Criminal Division has extra flexibility under R v Gould where liberty is at stake.
---4. The Mechanics: Judicial Tools for Managing Precedent
Judges have several specific legal mechanisms at their disposal when dealing with precedents:
1. Following:
Applying the ratio decidendi of an earlier relevant case because the material facts and legal principles are substantially identical.
2. Distinguishing:
A method used by a judge to avoid a binding precedent by showing that the material facts of the current case are genuinely different from those in the earlier case.
• Comparison Authority:
— In Balfour v Balfour [1919], a husband's domestic promise to pay his wife an allowance while living happily together was held not legally binding (no intention to create legal relations).
— In Merritt v Merritt [1970], the court distinguished Balfour because the couple were separated and made a formal agreement in writing; therefore, an intention to create legal relations existed.
3. Overruling:
When a higher court states in a different, later case that the legal principle decided by an earlier, lower court (or by itself under the Practice Statement) was incorrect and replaces it with a new rule (e.g., R v Shivpuri overruled Anderton v Ryan).
4. Reversing:
Occurs strictly within the same case on appeal, when a higher appellate court overturns the lower court's decision on a point of law (e.g., the Court of Appeal reverses a High Court ruling).
5. Disapproving:
A judge states in their judgment (usually obiter) that they believe an earlier decision from another court was incorrect, without formally overruling it.
Memory Trick: Reversing vs Overruling
• Reversing = Rearranging the same case on appeal.
• Overruling = Outlawing a different, older case.
Key Takeaway: Judges follow identical cases, distinguish cases with different material facts, overrule bad law in separate subsequent cases, and reverse decisions in the same case on appeal.
---5. Evaluation: Advantages and Disadvantages
In your \(15\)-mark Paper 1 essay, you must critically evaluate the doctrine of judicial precedent by balancing its strengths and weaknesses:
Advantages of Judicial Precedent
1. Certainty and Predictability:
Because courts follow past decisions, individuals and businesses know where they stand legally. Legal advisers can predict case outcomes, encouraging out-of-court settlements and saving legal costs (the central rationale in London Tramways).
2. Consistency and Fairness:
Treating like cases alike promotes justice and upholds the Rule of Law by ensuring decisions are not based on the personal bias or whim of an individual judge.
3. Flexibility and Growth:
The law can adapt quickly to changing social values and new technology without waiting for Parliament. Tools like the Practice Statement 1966 (e.g., Herrington, R v R) and distinguishing (e.g., Merritt v Merritt) allow outdated rules to be updated.
4. Precision and Practical Detail:
Precedents arise from real-life disputes involving genuine human problems, producing detailed, practical rules refined over hundreds of individual cases.
5. Time-saving:
Judges and lawyers do not have to spend time debating established points of law from scratch during every hearing.
Disadvantages of Judicial Precedent
1. Rigidity and Inflexibility:
Lower courts are bound to follow outdated or unjust precedents until a wealthy, determined litigant appeals all the way to the Supreme Court. Unjust rules can persist for decades.
2. Bulk and Complexity:
There are hundreds of thousands of reported cases. Finding the precise ratio decidendi buried inside long, multi-judge appellate judgments can be extremely difficult and time-consuming.
3. Retrospective Effect (Retrospectivity):
Judicial precedent applies backwards in time to the events that occurred before the trial. In criminal cases, this can mean a defendant is convicted for behaviour that was not clearly recognized as a crime when committed (e.g., R v R [1991]).
4. Illogical and Overly Technical Distinctions:
Judges eager to avoid an unjust binding precedent sometimes draw microscopic, hair-splitting distinctions between facts, making the law convoluted and confusing.
5. Undemocratic Judicial Law-Making:
Under the constitutional doctrine of the Separation of Powers, elected MPs in Parliament should make the law. Senior judges are appointed and unelected; major precedent-setting decisions can be seen as an infringement on parliamentary supremacy.
Key Takeaway: Precedent balances certainty and fairness against rigidity and undemocratic judicial law-making.
---6. Common Exam Pitfalls & Examiner Tips
Review these frequent student mistakes before your exam:
Mistake 1: Saying the Court of Appeal can use the Practice Statement 1966.
Correction: Only the Supreme Court has the power to use the Practice Statement 1966. The Court of Appeal is bound by its own decisions unless it meets one of the three Young v Bristol Aeroplane exceptions!
Mistake 2: Mixing up Reversing and Overruling.
Correction: Reversing happens within the same case going up on appeal. Overruling happens when a higher court replaces a legal rule from an entirely separate, earlier case.
Mistake 3: Forgetting the Court of Appeal Criminal Division flexibility.
Correction: Always mention R v Gould. The Criminal Division can depart from its own past decisions where the law was misapplied and an individual's liberty is at stake.
Mistake 4: Writing essays without case authorities.
Correction: Every concept must have an anchor case. Never mention distinguishing without Balfour and Merritt, or persuasive precedent without Howe/Gotts or R v R.
