Chief Justice Martha Koome on Wednesday morning sworn in a seven-member tribunal to probe suspended High Court Judge Said Chitembwe.
The tribunal will be chaired by Court of Appeal judge Mumbi Ngugi.
Koome asked Ngugi to accord the judge fairness and not to be swayed in any way in determining the petition.
She said the panel has a Cardinal duty to uphold the law and the Constitution while adjudicating the matter and ensuring that every party is accorded a fair hearing.
The tribunal was appointed by President Uhuru Kenyatta through a special gazette notice.
The Judicial Service Commission led by Koome had recommended the removal of Chitembwe after former Nairobi governor Mike Sonko alleged that he was influenced in determining a matter before him.
The JSC's probe found that the judge had a case to answer.
Chitembwe had indicated intentions to appeal the commission's findings.
