The fees of the special commissioner provided for by this chapter must be two hundred dollars per day, and in addition thereto, the special commissioner shall receive mileage from the commissioner’s residence to the place of trial the same as is allowed by law to sheriffs. The special commissioner may employ a stenographer and pay the expenses of the stenographer. Such expenses must be itemized by the commissioner and filed with the commissioner’s report and findings and audited and allowed by the governor. Witnesses giving testimony before such commissioner, the number to be limited by the commissioner, must be allowed the same fees as witnesses in district court. In proceedings to remove a county officer, such fees must be paid by the county upon allowance by the board of county commissioners in the same manner as other claims against the county, and if a municipal or township officer, then by the city council, board of city commissioners, or board of township supervisors, in the same manner as other claims against the municipality are paid.
