The Goldenberg commission he chaired between February 2003 and March 2003 brought down Justice Bosire.
Justice Nyamu had ordered the team not to wind up proceedings before calling prominent figures to testify, including former President Moi, ministers George Saitoti, Musalia Mudavadi, and former minister Nicholas Biwott, among others.
"He simply treated it as if it was not binding on him and ignored it," the vetting board commented.
Bosire was interviewed over his role as the judge that presided over the trial of Kenya Army officers implicated in the August 1982 coup attempt.
The killer blow for Judge OâKubasu were allegations that he was hosted in a London hotel by a man whose brother had a case before him, and that he presided over the case filed by a businessman who was close to him.
The board suggested a soft landing for the fallen judges, proposing that appropriate ways be found to make them useful in facilitating access to justice.
The removal of the four leaves 11 judges at the Court of Appeal, including seven who were elevated from the High Court in December last year. The seven will, however, be vetted starting today with their High Court colleagues.
The board is expected to conclude its business by the end of February next year, with an opportunity for extension of term by a year.
