Texas has a three-tiered court system. At the lowest level are justice of the peace courts and municipal courts that handle misdemeanors and smaller civil cases. Above them are county courts, and at the highest level are district courts that handle felonies, divorces, and larger civil cases. Appellate courts review trials to determine if proper procedures were followed and can order new trials or overturn verdicts. The Texas Supreme Court and Court of Criminal Appeals are the highest appellate courts, reviewing all death penalty cases and criminal cases respectively. Grand juries decide if someone should be indicted for a felony, while petit juries decide verdicts in trials.
