The Premier of the Northern Cape is the head of the provincial government, chosen by the members of the provincial parliament from amongst themselves. The Premier appoints Members of the Executive Council (MECs) to oversee the various departments of the provincial government. The Director-General is the non-political head of the provincial administration, while each department is led by a Head of Department. The current Premier is Zamani Saul of the African National Congress. Besides the Premier, the Executive Council consists of ten MECs overseeing eleven departments.
South Africa has a single national judiciary; there is no separate system of provincial courts. The Northern Cape Division of the High Court of South Africa in Kimberley has jurisdiction over all cases arising in the province, but generally handles only the most serious or high-profile criminal trials, high-value civil trials, cases involving judicial review of legislation or executive actions, and appeals from the magistrates' courts. Judges of the High Court periodically go on circuit to hear cases in parts of the province distant from Kimberley. Appeals from the High Court are to the national Supreme Court of Appeal and ultimately (if a constitutional matter is involved) to the Constitutional Court.
The province is divided into 26 magisterial districts and 6 sub-districts, each of which is served by a district magistrate's court. There are a further 24 branch and periodical courts to serve geographically dispersed districts. These district courts have jurisdiction over all criminal cases except murder, rape and treason and can impose a fine of up to R100,000 or a prison sentence of up to three years; and they have jurisdiction over civil cases where the value of the claim is less than R100,000. The regional magistrate's court for the Northern Cape, which sits at multiple locations in the province, has jurisdiction over all criminal cases except treason and can impose a fine of up to R300,000 or a prison sentence of up to fifteen years (or life in some circumstances). The regional court also has jurisdiction over civil cases where the value of the claim is less than R300,000, and divorce and family law cases.
