The principle of precedent, also known as stare decisis, is a cornerstone of both the US and UK legal systems. It ensures a degree of consistency and predictability in the application of law by requiring courts to adhere to prior decisions on similar legal issues. However, there are nuanced differences in how this doctrine is applied in each country.
What is the role of precedent in legal systems?
Precedent serves as a guiding principle in common law systems, where legal principles are derived not only from statutes but also from judicial decisions. It operates on the idea that similar cases should be decided similarly, ensuring fairness and stability in the law.
In essence, precedent creates a body of case law that serves as a reference point for judges and lawyers when interpreting and applying the law. It provides a framework for legal reasoning and helps to maintain consistency in the administration of justice.
How does the doctrine of precedent operate in the US legal system?
The US legal system follows a vertical and horizontal stare decisis model.
- Vertical Stare Decisis: This means that lower courts are bound by the decisions of higher courts within their jurisdiction. For example, a state trial court in California must adhere to rulings made by the California Supreme Court.
- Horizontal Stare Decisis: Courts are generally expected to follow their own previous decisions. If a court has already ruled on a similar issue, it should apply the same legal principles unless there are compelling reasons to deviate.
A classic example of precedent in action is the landmark US Supreme Court case Brown v. Board of Education. This decision overturned previous rulings that had upheld racial segregation in schools, establishing a new precedent that paved the way for desegregation.
How does the doctrine of precedent operate in the UK legal system?
The UK also adheres to vertical and horizontal stare decisis, but with some key distinctions.
- Vertical Stare Decisis: The decisions of the UK Supreme Court are binding on all lower courts in the UK. However, before the UK’s departure from the European Union, decisions of the Court of Justice of the European Union (CJEU) took precedence over UK case law on matters of EU law.
- Horizontal Stare Decisis: While the UK Supreme Court is not strictly bound by its own previous decisions, it is generally reluctant to depart from them unless there are compelling reasons to do so. This approach maintains a degree of consistency while allowing for flexibility when necessary.
An example of the UK Supreme Court departing from its own prior decisions is the R (Miller) v Secretary of State for Exiting the European Union case, which clarified the role of Parliament in the Brexit process, differing from some earlier interpretations.
What are the key differences in how precedent is applied in US and UK courts?
Several factors contribute to variations in the application of precedent:
- Persuasive vs. Binding Authority: In the US, decisions from other jurisdictions may be considered persuasive but not binding. However, in the UK, decisions from certain Commonwealth countries, while not strictly binding, can carry significant persuasive authority.
- Overturning Precedent: US courts are generally more willing to overturn their own prior decisions if they are deemed outdated or flawed. UK courts are more cautious in this regard, emphasizing the importance of legal stability.
- Distinguishing Cases: Both systems allow courts to distinguish cases based on their unique facts or legal principles. This means that a court can decide not to apply a precedent if the current case differs significantly from the previous one.

| Persuasive Authority | Decisions from other jurisdictions can be persuasive | Decisions from certain Commonwealth countries can be persuasive |
| Overturning Precedent | More willing to overturn prior decisions | More reluctant to overturn prior decisions |

FAQs
Does the US Supreme Court always have to follow its own precedents?
While the Supreme Court generally adheres to its prior decisions, it has the power to overturn them in rare cases. This usually happens when a previous decision is deemed to be fundamentally flawed or no longer reflects current legal or societal values.
Can lower courts in the UK ever refuse to follow a Supreme Court decision?
In very exceptional circumstances, a lower court may refuse to follow a Supreme Court decision if it believes the decision was made per incuriam (through lack of care) or if there has been a subsequent change in the law. However, this is rare and requires strong justification.
How does the role of precedent affect legal certainty?
Precedent promotes legal certainty by providing a degree of predictability in how courts will decide similar cases. This allows individuals and businesses to understand their legal rights and obligations more clearly.
How has the UK’s departure from the European Union impacted the role of precedent?
With the UK no longer bound by EU law, the CJEU decisions are no longer automatically binding on UK courts. However, these decisions may still be considered persuasive authority, depending on the specific circumstances of the case and the area of law involved.
