How Courts Work

Courts decide disputes by applying law to facts, and their power depends on the level of court and the issue before them. The hierarchy, review powers and the handling of constitutional cases all shape how courts work in practice.

1. Start with the court hierarchy, not the headline

Most legal disputes begin in a lower court and only move upward if the law allows it. In South Africa, as in many African systems shaped by common law and constitutional law, the hierarchy matters because each court has a different job. A magistrates’ court may hear smaller civil claims or less serious criminal matters, while a High Court deals with more serious issues and can hear appeals or reviews in some cases. The Constitutional Court sits at the top for constitutional matters and has the final word on the Constitution.

If you are trying to understand a case, first ask three things: which court heard it, what power that court had, and whether the matter was about facts, law, or rights. That makes the judgment much easier to follow. It also helps you see why one court can change a decision and another cannot.

  • Check the court name at the top of the judgment
  • Note whether it was an original hearing, appeal, or review
  • Look for the legal issue before reading the full facts

2. Trial courts find facts, appeal courts test the decision

Trial courts are mainly concerned with evidence. They hear witnesses, consider documents, and decide what probably happened. Appeal courts usually do not start again with fresh evidence. Instead, they ask whether the lower court applied the law correctly, weighed the evidence properly, or made an error serious enough to change the outcome. That distinction is important because an appeal is not a do over.

If a judge or magistrate misread a rule, ignored a key legal principle, or reached a conclusion no reasonable court could reach, an appeal may succeed. But if the complaint is simply that one side lost and wants another chance, the appeal may fail. In practice, many people confuse disappointment with legal error, and that is where the trouble starts.

  • Trial court: hears evidence and decides facts
  • Appeal court: checks for legal or procedural error
  • New evidence is usually limited on appeal

3. Review powers protect fair process

Review is different from appeal. A review court asks whether the process was lawful, fair and within the powers given by law. This can matter where a lower court, tribunal, board or administrative official acted unfairly, misunderstood the law, or exceeded its authority. Review is about legality and fairness, not simply whether the result was unpopular.

In a review, the court may look at whether the correct procedure was followed, whether the decision-maker was biased, or whether relevant information was ignored. In South Africa, review powers are especially important when public bodies affect rights, permits, discipline, procurement or other administrative decisions. The question is often whether the decision maker acted within the law, not whether the judge would have made the same call.

  • Was the decision-maker authorised to act?
  • Was the hearing fair and the procedure lawful?
  • Were relevant facts and reasons properly considered?

4. Constitutional cases begin with rights and reach further than one dispute

Constitutional cases ask whether a law, policy, act or omission is compatible with the Constitution. These cases can deal with equality, dignity, freedom of expression, fair trial rights, housing, education, access to information, and the limits of state power. The court may interpret a statute, strike down a rule, or declare that a public body must act differently. The focus is not only on one party’s problem but on how the law works for everyone else too.

To understand a constitutional case, read the issue before the remedy. A court may accept that a rule was lawful in the past but still find that it must be changed going forward. It may also develop the common law where old rules do not fit a constitutional democracy. That is why constitutional judgments often sound broader than ordinary civil or criminal matters.

Across South Africa, Kenya, Nigeria, Ghana and Zambia, the same basic idea applies: constitutional law sets the highest standards for state conduct, even though the exact court structure differs from country to country.

5. A practical checklist for reading any judgment

Good court reading starts with structure. Use this simple checklist when you open a judgment or case summary. It will save time and reduce confusion, especially when the language is formal or the facts are dense. If the matter involves local government, land, policing, detention or school discipline, the procedure can matter as much as the final order.

  • Identify the court and the date of the judgment
  • Find the parties and the type of case
  • Ask whether the matter is about facts, law or constitutional rights
  • Read the order first, then the reasons
  • Check what the court actually decided and what it did not decide
  • Look for any limit on who can appeal or review the matter

If you still feel unsure, write down the legal question in one sentence. That simple step often reveals whether the case is about evidence, procedure or constitutional interpretation. A clean summary makes the rest easier to follow, even when the judgment is long.

6. Why court rules matter beyond the courtroom

Court decisions do more than settle disputes. They shape how public bodies act, how lawyers advise clients, and how ordinary people understand their rights. A ruling on review can change a licensing process. A constitutional case can change how a law is read across the country. A judgment on appeal can settle a point of law that lower courts must follow.

That is why it helps to read courts with patience. The language can be formal, but the structure is usually simple once you know what to look for. Start with the hierarchy, separate appeal from review, and ask whether the case is really about rights, process or evidence. Once you do that, the system begins to make sense.

Questions this explainer answers

What is the difference between a review and an appeal?

An appeal asks whether the lower court or tribunal made a legal mistake in reaching its decision. A review asks whether the process was lawful, fair and within the powers given by law.

Why do constitutional cases matter so much?

They test whether laws, policies and government action fit the Constitution. These cases can affect more than one dispute because they often shape how the law must be applied in future.

Can a court change a decision without hearing the case again?

Yes, sometimes. An appeal court may change a decision if there was a legal error, while a review court may set aside a decision if the process was unfair or unlawful.
