Understanding Judicial Precedent

Judicial precedent is when past decisions of judges create law that other judges must follow. It's like a legal domino effect - when a higher court makes a decision, all the courts below them have to follow that same reasoning for similar cases.

This system relies on three key Latin terms you need to know. Stare decisis means "stand by what has been said" - basically, if a previous case dealt with the same legal issue, courts should follow that decision. This creates certainty and fairness in the law.

When a judge gives their judgement, there are two important parts. The ratio decidendi is the legal reasoning behind the decision - this bit becomes binding precedent that other courts must follow. The obiter dicta is everything else the judge says - it's just commentary and only persuasive, not binding.

Key Point: The ratio decidendi is what creates binding precedent - it's the part that actually becomes law for future cases.

The Court Hierarchy System

The court hierarchy determines who has to follow whose decisions. At the top sits the Supreme Court, which binds all courts below it but can usually choose whether to follow its own previous decisions (thanks to the 1966 Practice Statement).

The Court of Appeal is bound by the Supreme Court and usually by its own decisions too. Below that are the Divisional Courts (King's Bench, Family, and Chancery), which must follow all courts above them.

At the bottom are the courts that don't create precedent - the Crown Court, Magistrates Court, and County Court. These are bound by all courts above them but their decisions don't become law for other courts to follow.

Original precedent happens when judges create completely new law because no previous precedent exists. Only the Supreme Court and Court of Appeal can do this, though critics argue it's undemocratic since judges aren't elected.

Remember: Higher courts bind lower courts - it's that simple. The higher up the hierarchy, the more power to create binding law.

Types of Precedent

Not all court decisions carry the same weight. Binding precedent means higher courts bind lower courts, and like cases must be decided alike. This comes from the ratio decidendi and creates legal certainty.

Persuasive precedent doesn't bind courts, but judges might be influenced by these decisions. This includes decisions from the Judicial Committee of the Privy Council, lower courts that higher courts later agree with, and obiter dicta statements from previous cases.

Dissenting judgements (where judges disagree with the majority) can also be persuasive. Sometimes these minority opinions get picked up in later cases or on appeal. Decisions from other common law countries like Canada or Australia might also persuade British judges.

Even decisions from the European Court of Human Rights can be persuasive, though if there's a conflict, English courts must follow English precedent for certainty.

Think of it this way: Binding precedent is law you must follow; persuasive precedent is advice you might choose to follow.

How Courts Avoid Precedent

Sometimes judges need to avoid following precedent to reach a fair result. Following means applying the precedent when facts are similar, but there are several ways to avoid this.

Distinguishing lets judges find material differences between cases to justify different outcomes. The classic example is Balfour v Balfour (where a married couple's agreement wasn't binding) being distinguished from Merritt v Merritt (where the couple was separated, making it binding).

Overruling happens when senior judges disagree with an earlier decision from a lower court, usually because it's outdated or wrong. Reversing occurs when a higher court changes a lower court's decision on appeal.

The Court of Appeal can avoid precedent using exceptions from Young v Bristol Aeroplane Company: when there are conflicting past decisions, when a Supreme Court decision effectively overrules them, or when the decision was made in error. The Supreme Court can use the 1966 Practice Statement to depart from its own previous decisions "where it appears right to do so."

Quick tip: Think of these methods as escape routes - they let judges avoid unfair or outdated precedents while maintaining legal stability.
