Kisii Assembly members on Tuesday unanimously voted to kick out the County Public Service Board after an indicting report by House Labour Committee.
At least 69 of the 71 Assembly members voted in favour of the ouster.
The outcome of the verdict translated to 99 per cent vote to surpass the 75 vote margin threshold required to sack the board.
The Board officials were for the better part of the last two weeks grilled by the Naftal Onkoba-led committee.
Petitioner Benson Atika had sought their removal on, among other grounds, failure to follow the due process in recruitment of staff.
He accused the board chaired by Nancy Nyamwange of undertaking irregular promotions as well as extending the employment of staff some who had attained the mandatory retirement age of 60.
Nyamwange was deputised by Ondiba Bogonko.
Other members kicked out alongside Nyamwange include Patrick Momanyi, John Ndege and Judy Nyakerario.
Atika had in his petition also accused the board officials for irregularly engaging in converting casual employment into contract terms and subsequently permanent and pensionable terms without following laid-down guidelines.
Nominee Callen Magara filed the motion to have the entire board ejected for abuse of office.
The motion was backed by Majority Leader Henry Moracha (Bassi Central) and nominees Celestine Mose and Lilan Omundi.
The motion only needed a majority threshold of 75 votes to sail through.
Dissenter Dolphin Bwari said the board officials were not given a fair chance to defend themselves.
