Criminal courts are usually trial courts with the authority to hear only matters relating to criminal prosecutions—and are said to have exclusive jurisdiction of criminal matters within the county, for example. And in some states there are appellate courts with exclusive jurisdiction over criminal appeals. For example, in Texas, the intermediate courts of appeals hear both civil and criminal cases, but the Texas Court of Criminal Appeals is the court of last resort for criminal matters, and hears appeals of criminal matters from the intermediate courts of appeal.
In Oregon, criminal courts are primarily structured with Circuit Courts at the trial level, which have the authority to hear criminal cases within their respective counties. These courts handle misdemeanors, felonies, and other criminal proceedings. Above the Circuit Courts, the Oregon Court of Appeals serves as the intermediate appellate court, which reviews decisions made by the lower courts, including criminal cases. The Oregon Supreme Court is the highest court in the state and has the discretion to review decisions made by the Court of Appeals. Unlike Texas, where there is a separate Court of Criminal Appeals for criminal matters, Oregon does not have a specialized appellate court exclusively for criminal appeals; both civil and criminal appeals are heard in the same appellate courts.
