The jurisdiction of the county personnel committee to conduct discharge, removal, or suspension hearings shall be limited to those cases not involving death of a county employee or any person under the care or custody of a county employee. Whenever the county personnel committee finds that a case involves a death of a county employee or any person under the care or custody of a county employee, the committee shall immediately transfer the case to superior court. Any determination made by the county personnel committee that a case involves the death of a county employee or any person under the care or custody of a county employee shall be inadmissible as evidence in any civil action, arising from such death, against the county or any county official or employee.
