YOUR FIRST FIVE MINUTES

You do not need a law class to start asking good questions. Pick the route that fits where you are, and take it one step at a time.

Middle school? Start with the basics and a fictional case. High school? Choose a study guide or a decision file. Teachers can find a lesson and discussion ideas in For Teachers.

First steps: meet the courtroom

This is a simplified map of a jury trial. Not every case has a jury, and Teen Court has its own process.

  1. Judge: manages the proceeding and decides questions of law.
  2. Lawyers: present their clients’ arguments and question witnesses.
  3. Witnesses: give testimony about relevant facts.
  4. Jurors: consider the evidence and decide the factual questions assigned to them under the judge’s instructions.

Think of those roles as different jobs, not different levels of importance. A fair process depends on people taking each job seriously. Check the U.S. Courts glossary when a word is unfamiliar.

A few words worth knowing

Evidence

Information presented to help establish facts. Ask where it came from, whether it is reliable, and what it actually shows.

Verdict

A jury’s decision about the facts. It is different from the reasoning in a judge’s written opinion.

Appeal

A request for a higher court to review a lower court’s decision. It is not simply a new jury trial.

Precedent

An earlier court decision that can guide a later case. Some authority must be followed; some can be considered because its reasoning is useful.

Majority, concurrence, and dissent

These labels help you follow agreement and disagreement in an opinion. A concurrence can agree with the judgment while giving different reasons. A dissent disagrees with the result.

Go deeper: build a case note

Read one explainer, then try a five-line note: facts, question, answer, reason, and what is still uncertain. Keep the original link beside your notes.

Next, visit Decisions & Debates or Contested Cases. Try explaining an argument before deciding whether you agree with it.

Ready to test your thinking?

Try a fictional case in Try a Case. There is no score to chase. The goal is to explain your reasoning and notice what could change your mind.
