The interviews commenced on November 19 and are to end on Thursday.
Justice Byrum Ongaya in declining to issue the orders sought by five of the petitioners said their application was not justified.
David Too, Elijah Oluoch, Ali Mohamed, Sandra Mwita and Wilfred Barasa filed the application saying the procedural process of shortlisting candidates was marred with procedural improprieties to favour some applicants and disadvantage other candidates.
The five who applied for the vacant position told the court that 4 of the 14 shortlisted candidates from a list of 172 were employees of the commission.
The process they said failed to meet the threshold as it failed to enlist the services of an independent professional expert to conduct the process of shortlisting candidates thereby disadvantaging non-commissioned employees.
The Ad was dated 17 September 2024 with the shortlisted candidates set to commence their interviews on November 19.
The petitioners cited section 16 of the commission which provides that the commission shall through an open, transparent and competitive recruitment process and with the approval of the National Assembly appoint a suitable qualified person to be the secretary to the commission.
But this, they say, was not adhered to as the process undertaken by the commission failed to enlist the services of an independent body or professional experts to conduct the process of shortlisting candidates.
The interviews which commenced on November 16 seek to replace Twalib Mbarak who has been at the helm of the anti-graft body since 2019.
He is set to end his term on January 19 after concluding his six-year term.
A total of 14 candidates from 172 are battling it out for the job.
They are Stephen Ngowa, Doreen Muthaura, Jackson Mue, Joseph Onyango, Paul Maina, Victor Okongo, Peter Lomulen and Obadiah Keitany.
Others are John Ole Moyaki, David Too, Abdi Mohamud, Justus Mwangi, Mohamed Mmaka and Waweru Karanja.
