Legal Precedent: Understanding its Role in Court Decisions 

Table of Contents

As a business owner, it is possible that you could find yourself part of court proceedings at some stage. This could be, for example, because the other party in a commercial contract has not fulfilled their obligations. While court litigation should be a final resort to resolving a business dispute, there are rules and legal principles you must understand if you choose to undertake this option. One significant rule is binding precedent which may apply where your case is similar to a case decided previously by the court. This article will explain legal precedent and its role in a judge’s decisions.

A legal precedent is where a court has decided on a case, which is then considered binding on court cases of a similar nature. Generally, a binding precedent will arise where the:

  • court making the original decision was either equal or higher in rank to the currently deciding court; and
  • decision concerns the same point of law. 

This means that lower court decisions do not bind decisions in superior courts. 

Legal precedent is significant to any commercial court litigation, as it can be highly influential on the decisions made in your case. In other words, losing or winning in court may depend on whether your case aligns with the legal principles the precedent outlines. Although it is an essential concept to understand, navigating legal precedent can be confusing. Therefore, it is essential to obtain advice from a knowledgeable litigation lawyer when you are involved in commercial litigation. Their expertise and experience with legal precedent will allow them to advise you accordingly.

When you take a commercial case to court, this is classed as civil litigation. There is a hierarchy of courts in civil litigation, which beginning with the highest, are as follows:

  1. Supreme Court;
  2. Court of Appeal;
  3. High Court, and 
  4. County Court.

Therefore, some examples of how legal precedent applies are:

  • the decision of the Supreme Court binds the Court of Appeal;
  • the Court of Appeal is bound by previous decisions of the Court of Appeal and 
  • decisions of the Court of Appeal do not bind the Supreme Court.

However, you should note that the doctrine of legal precedent is not always straightforward, and other rules may affect it. We discuss some below in the context of different courts.

The Supreme Court

Historically, the Supreme Court has followed the doctrine of legal precedent, deciding a given court case based on legal principles established in a previous, similar one. However, in 1966, the Practice Statement 1966 allowed for an exception to this rule. It details that although these decisions are usually binding, the court may, if necessary, make an exception. This may be in circumstances where following precedent could, for example, cause injustice. Nonetheless, the Supreme Court has not used these exceptions liberally. Instead, the court rarely treats a decision as not legally binding on a subsequent case.

The Court of Appeal

The Court of Appeal is bound by its previous decisions on the same legal issues in subsequent cases. However, there are three exceptions to this, which evolved from the case of Young v Bristol Aeroplane Co in the 1940s. These are:

  1. Where a previous decision by the Court of Appeal was changed by a decision made on the same point by the Supreme Court.
  2. Where two decisions of the Court of Appeal on the point in question were different, meaning the Court can decide which is binding.
  3. When a previous Court of Appeal decision is made incorrectly, such as when it does not consider a relevant legal issue, rule or principle that it should have.

Court of the First Instance

A court of the first instance is either the High Court or the County Court, the two lower courts in the civil court hierarchy. It is essential to understand that decisions of the High Court bind the County Court, as the High Court is higher than it. However, these two courts are different to the superior courts in that the judges do not legally need to make the same decision as one made previously by the court. Still, the judges will typically follow a decision on the same point of law to maintain consistency.
