Types of Precedent (OCR A-Level Law): Revision Notes
Types of Precedent
Understanding the different types of precedent is essential to grasping how the doctrine of judicial precedent operates within the English legal system. Precedent can take several forms, each with different levels of authority and application. The main categories are binding precedent, persuasive precedent, and original precedent. Additionally, judges have specific methods for dealing with precedents from earlier cases.
Binding precedent
The English legal system operates through a hierarchical court structure, meaning courts are ranked according to their seniority. Higher courts have authority over lower courts, and decisions made by senior courts must be followed by those below them in the hierarchy. This creates a system of certainty and consistency in the law.
Binding precedent is a decision made in an earlier case by a higher court which must be followed in later cases. The binding element comes from the ratio decidendi (the legal reasoning) of the senior court's judgment. Lower courts have no choice but to apply this precedent when faced with similar cases involving the same legal principles.
The hierarchical structure ensures that when the Supreme Court establishes a principle of law, the Court of Appeal, High Court, and all lower courts must follow that principle in subsequent cases. This binding nature ensures uniformity in legal decisions across the court system.
Persuasive precedent
Not all precedents carry mandatory authority. Persuasive precedent refers to a decision which does not have to be followed by later cases, but which a judge may decide to follow if they find the reasoning compelling. While judges are not obliged to apply persuasive precedent, they must provide reasons if they choose not to follow it.
Persuasive precedents can arise from several sources:
Courts that do not bind: The Judicial Committee of the Privy Council is the most significant example. Although it hears appeals from Commonwealth countries and certain UK jurisdictions, its decisions are not binding on English courts. However, judges often find its reasoning persuasive, particularly on complex legal issues, as it is composed of senior judges including Supreme Court Justices.
Lower courts in the hierarchy: A decision from a court lower in the structure may be persuasive to a higher court. For instance, a High Court judgment might influence the Court of Appeal if the legal reasoning is particularly sound, though the Court of Appeal is not bound to follow it.
Obiter dicta: Statements made by judges that do not form part of the ratio decidendi are known as obiter dicta (things said by the way). These are persuasive rather than binding. Obiter dicta often explore hypothetical situations or discuss legal principles not directly relevant to the case at hand, but they can influence future judicial thinking.
Original precedent
Sometimes a case comes before the courts involving a legal question that has never been considered before. In such situations, there is no existing precedent to guide the judge's decision. This creates what is known as original precedent – a situation where the point of law has never been considered before, meaning the normal doctrine of judicial precedent cannot apply because there is no precedent to follow.
Landmark Example: Donoghue v Stevenson (1932)
This case established the modern law of negligence and the concept of the 'neighbour principle'. Before this case, no clear legal framework existed for determining when someone owed a duty of care to another person. The House of Lords had to create new law to address this gap, making it a classic example of original precedent in action.
Original precedent typically arises in two main contexts:
New technologies: As society develops new technologies, novel legal situations emerge. Courts must determine how existing legal principles apply to circumstances that previous generations could not have envisaged. For example, early cases involving internet defamation, data protection, or artificial intelligence required judges to establish new legal principles.
Unprecedented factual situations: Sometimes unique combinations of facts arise that have no parallel in legal history, requiring judges to reason from first principles.
The concept of original precedent raises an important constitutional question about the judicial role: When judges create original precedent, are they making new law or merely declaring law that already exists? This debate touches on the separation of powers and the proper boundaries of judicial function.
Operation of judicial precedent
When judges encounter precedent from earlier cases, they have several options for how to deal with it. Understanding these mechanisms is crucial for appreciating how the law develops and adapts over time. The three main methods are overruling, reversing, and distinguishing.
Overruling
Overruling occurs when a court in a later case states that the decision in an earlier case is wrong. This typically happens in two scenarios.
First, a higher court may overrule a decision made by a lower court in a previous case. For example, the Supreme Court can overrule a decision of the Court of Appeal. This ensures that incorrect legal principles do not persist in the legal system.
Second, the Supreme Court can use the Practice Statement (1966) to overrule its own previous decisions when it appears right to do so. This power is exercised sparingly and usually when the previous decision is causing injustice or has become outdated.
Worked Example: R v Jogee (2016)
This case overruled the previous law on joint enterprise established in R v Powell and R v English (1999).
What happened: The Supreme Court concluded that the earlier cases had taken a wrong turn in the law of secondary liability, making it too easy to convict defendants of serious crimes.
The outcome: This overruling changed the law fundamentally, requiring proof that the secondary party intended to assist or encourage the crime, raising the threshold for conviction.
Reversing
Reversing involves a higher court overturning the decision of a lower court on appeal. Crucially, this occurs within the same case as it moves up the court structure. The case is not concluded at the lower court level; instead, one party appeals the decision to a higher court.
Re Pinochet (1999) provides an illustration. The House of Lords initially decided that the former Chilean dictator Augusto Pinochet could be extradited. However, it later emerged that one of the judges had connections to Amnesty International, which was involved in the case. A differently constituted House of Lords reversed the earlier decision, demonstrating that even the highest court can reverse its own decisions when procedural irregularities occur.
Distinguishing
Distinguishing allows a judge to avoid following a precedent by demonstrating that the material facts of the current case are sufficiently different from the case that set the precedent. If the judge finds that a distinction can be drawn between the two cases, they are not bound by the previous case.
This technique requires careful analysis of the facts. The judge must identify which facts were material (legally significant) in the earlier case and explain why the current case differs in those material respects.
Worked Example: Merritt v Merritt (1971) distinguished Balfour v Balfour (1919)
In Balfour v Balfour: A husband and wife made an informal agreement while still living together in a harmonious relationship. The court held this was a domestic arrangement without legal intent.
In Merritt v Merritt: The parties had separated and made a formal written agreement.
The distinction: The Court of Appeal distinguished Balfour because the different circumstances meant there was intention to create legal relations. The material facts were sufficiently different to reach a different legal conclusion.
A more recent example involves occupiers' liability. In White Lion Hotel v James (2021), the window sash was broken, whereas in Geary v JD Wetherspoon (2011), the bannister was not broken. These factual distinctions were material to determining whether the occupier had breached their duty of care, allowing the courts to reach different conclusions despite similar factual scenarios.
Key Points to Remember:
-
Binding precedent is mandatory and must be followed by lower courts; it comes from higher courts in the hierarchy and ensures consistency in legal decisions
-
Persuasive precedent is optional and may be followed if the judge finds the reasoning convincing; sources include the Privy Council, lower courts, and obiter dicta statements
-
Original precedent arises when no previous case law exists on a point of law, often occurring with new technologies or unprecedented situations (e.g., Donoghue v Stevenson)
-
Judges can deal with precedents through overruling (declaring an earlier decision wrong), reversing (overturning a decision on appeal in the same case), or distinguishing (showing material factual differences)
-
The hierarchical structure of courts is essential for the precedent system to function effectively, with senior courts binding those below them
