The Judges

South Dakota circuit judges are elected in a nonpartisan election for an eight-year term (S.D. Const. Art. V, section 7; SDCL 16-6-3); a mid-term vacancy is filled by the Governor from two or more nominees of the Judicial Qualifications Commission. Magistrate judges, who in practice handle most rural first appearances and bail-setting under SDCL 16-12B-7, are not elected: the presiding judge of the circuit nominates them and the Supreme Court approves or disapproves the appointment (SDCL 16-12B-1.2); full-time magistrates serve four-year terms, part-time magistrates serve at the presiding judge's pleasure (SDCL 16-12B-1.3). Named circuit or magistrate judges for Grant County were not located from any source opened.
