Which court has original jurisdiction over all criminal and civil matters not assigned to another court?

The Circuit Court in Mississippi has original jurisdiction over all criminal and civil matters that are not assigned to another court. This means it is the primary court where these types of cases are first filed and adjudicated. This includes a wide range of cases involving felony crimes, significant civil claims, and various appeals from lower courts. The Circuit Court functions at a higher level than other courts concerning the scope of its jurisdiction, making it the main trial court for serious matters in the state.

In contrast, Chancery Courts primarily handle matters related to equity, such as divorce, child custody, and wills, meaning they do not have the same general jurisdiction for criminal and civil cases. District Courts generally address lesser criminal offenses and certain civil matters, but their jurisdiction is limited compared to the broader powers of the Circuit Court. City Courts usually focus on municipal ordinance violations and minor civil cases, also having a narrower jurisdiction. Thus, the Circuit Court stands out as the court endowed with original jurisdiction for all matters that don't specifically fall under the purview of the other mentioned courts.
