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 South Dakota, criminal courts are primarily responsible for handling criminal prosecutions. These courts have exclusive jurisdiction over criminal matters within their respective counties. The circuit courts in South Dakota serve as the trial courts for criminal cases, and they are organized into seven judicial circuits. For criminal appeals, South Dakota has a unified system where the South Dakota Supreme Court serves as the highest court and the court of last resort. It hears appeals directly from the circuit courts. Unlike Texas, which has a separate Court of Criminal Appeals as the highest court for criminal matters, South Dakota does not have an intermediate appellate court with exclusive jurisdiction over criminal appeals. Instead, the South Dakota Supreme Court handles appeals for both civil and criminal cases.
