Mississippi Code Title 9. Courts § 9-9-9

The county judge shall not practice law in any of the courts of the county wherein he holds court, but this prohibition shall not prohibit the judges of the county courts from practicing in any of the courts so far as to enable them to bring to a conclusion cases actually pending when they were appointed or elected, in which such county judges were then employed as provided in Section 9-1-25, Mississippi Code of 1972, for judges of the circuit court and chancellors.
