Welcome to the World of Judicial Precedent!

Have you ever wondered how judges make decisions? Do they just make it up as they go along? Fortunately, the answer is no! In the English legal system, judges follow a "follow the leader" rule called Judicial Precedent. This ensures that the law is consistent, fair, and predictable.

In this chapter, we will explore how past decisions guide future ones and what happens when a judge thinks a past rule needs to change. Don't worry if it sounds a bit technical—we'll break it down step-by-step!

1. What is the Doctrine of Judicial Precedent?

The system is based on the Latin phrase stare decisis, which means "to stand by things decided." Essentially, it means that once a point of law has been decided in a case, that rule should be followed in similar future cases.

This creates certainty in the law. If you know how a judge ruled yesterday on a specific issue, you can be fairly sure how they will rule today on the same issue.

The Anatomy of a Judgment

When a judge finishes a case, they give a long speech explaining their decision. We look for two specific things in that speech:

1. Ratio decidendi: This is the "reason for the decision." It is the legal principle or rule that the judge used to reach their conclusion. This is the part of the judgment that is binding (must be followed) on other judges.

2. Obiter dicta: This means "other things said" or "by the way." These are extra comments or hypothetical thoughts the judge had. For example, a judge might say, "If the facts had been different in this way, I might have decided like this..." These comments are not binding, but they can be persuasive.

Quick Tip: Think of the Ratio as the main recipe for a cake, and the Obiter as the judge's suggestions for different toppings. You must follow the recipe to make the cake, but the toppings are optional suggestions!

2. The Hierarchy of the Courts

For precedent to work, there has to be a "ladder" of authority. Higher courts tell lower courts what to do. If a high court makes a decision, all the courts below it must follow that rule.

The hierarchy (from highest to lowest) generally looks like this:

  1. The Supreme Court: The highest court in the UK. Its decisions bind all lower courts.
  2. The Court of Appeal: Binds itself (usually) and all lower courts.
  3. The High Court: Binds lower courts.
  4. Inferior Courts: (Magistrates' Court and County Court). These courts do not create precedent; they just follow the rules set by the courts above them.

3. Types of Precedent

Not all precedents are the same. Depending on where they come from, they have different "strengths":

  • Binding Precedent: A rule from a higher court that a lower court must follow.
  • Original Precedent: This happens when a judge has to decide a point of law that has never been seen before. Because there is no "leader" to follow, the judge creates a new rule.
  • Persuasive Precedent: A rule that a judge does not have to follow, but they might choose to because it seems like a good idea. This can come from Obiter dicta, lower courts, or even courts in other countries.

4. Flexibility: How the Law Changes

If judges always followed the past, the law would never move forward! There are ways for judges to avoid following a precedent that seems outdated or wrong.

The Supreme Court and the Practice Statement

Originally, the highest court was bound by its own past decisions. However, in 1966, the Practice Statement was issued. This allows the Supreme Court to depart from its own previous decisions when "it appears right to do so." This gives the law the flexibility to change with modern times.

The Court of Appeal and Young v Bristol Aeroplane Co (1944)

The Court of Appeal is usually bound by its own past decisions to keep the law stable. However, a famous case called Young v Bristol Aeroplane Co (1944) set out three exceptions where the Court of Appeal can ignore its own past rules:

  1. If there are two conflicting past decisions of the Court of Appeal, it can choose which one to follow.
  2. If a past decision of the Court of Appeal has been (effectively) overruled by the Supreme Court.
  3. If the past decision was made per incuriam (by mistake), meaning the judge forgot to look at a relevant Act of Parliament or a binding case.

The Three "Tools" of Judges

Judges use these three methods to handle precedents:

  • Distinguishing: This is the most common tool. A judge finds that the facts of the current case are different enough from the past case that they don't have to follow the old rule. "The old rule was about a blue car, but this case is about a red bicycle, so it's different!"
  • Overruling: A higher court states that a legal rule set by a lower court in a different, previous case was wrong and should no longer be used.
  • Reversing: This happens in a single case on appeal. For example, if the High Court decides a case one way, the Court of Appeal might "reverse" that decision and say the other side wins.

5. Law Reporting

How do judges know what the precedents are? They look them up! Law Reporting is the process of writing down and publishing judgments. For precedent to work, we need accurate records of the Ratio decidendi so lawyers and judges can study them.

Key Takeaway Review

- Stare decisis: Stand by the decision.
- Ratio decidendi: The binding reason for the decision.
- Obiter dicta: Persuasive comments made "by the way."
- Hierarchy: Higher courts bind lower courts.
- Practice Statement: Allows the Supreme Court to change its mind.
- Young v Bristol Aeroplane: Provides the only "escape routes" for the Court of Appeal.
- Distinguishing: Avoiding a precedent because the facts are different.

Don't worry if this seems tricky at first! The main thing to remember is that Judicial Precedent is a balance between Certainty (following the past) and Flexibility (changing the law when necessary).
