Court systems are structured organizations that handle legal disputes and ensure justice is served. They operate at various levels, including local, state, and federal courts, each with specific jurisdictions. Courts can address criminal cases, where the government prosecutes individuals for breaking laws, and civil cases, which involve disputes between private parties. Judges, who are trained legal professionals, preside over court proceedings and make decisions based on the law. In addition to judges, court systems often include jurors, who are citizens selected to evaluate evidence and determine the outcome of a trial. Overall, court systems play a crucial role in maintaining order and upholding the rule of law.
