Judges interpret the law to determine how a trial will proceed, which is particularly important when unusual circumstances arise for which standard procedures have not been established. They ensure that hearings and trials are conducted fairly and the legal rights of all involved parties are protected. In trials in which juries are selected to decide the case, judges instruct jurors on applicable laws and direct them to consider the facts from the evidence. For other trials, judges decide the case.
A judge who determines guilt in cases may impose a sentence or penalty on the guilty party. In civil cases, the judge may award relief, such as compensation for damages, to the parties who win the lawsuit. Some judges, such as appellate court judges, review decisions and records made by lower courts, and make decisions based on lawyers’ written and oral arguments.
