Which court has original jurisdiction over all felony cases according to the Code of Criminal Procedure?

The District Court holds original jurisdiction over all felony cases as outlined in the Texas Code of Criminal Procedure. This means that felonies, which are serious criminal offenses, are initially tried in the District Court rather than being directed to lower courts. The structure of the judicial system assigns District Courts the authority to handle significant issues, such as criminal cases that involve severe penalties.

In contrast, other courts mentioned typically deal with less serious offenses. For example, County Courts may have jurisdiction over certain misdemeanors and appeals from Justice Courts, which often handle minor civil and criminal matters. Appellate Courts are primarily responsible for reviewing decisions made by lower courts, rather than conducting original trials. Hence, the correct answer highlights the specific role of District Courts in the Texas judicial system concerning felony cases.
