Nearly 400 magistrates and various commissioners on Friday took the oath of allegiance at the High Court in Nairobi, a few hours after the promulgation of the Constitution.
The commissioners including members of the Committee of Experts, Truth, Justice and Reconciliation Commission, Kenya National Commission on Human Rights, Teachers Service Commission and Public Service Commission took the oath before Chief Justice Evan Gicheru.
Others commissioners were members of Interim Independent Electoral Commission, Interim Boundaries Commission and the National Cohesion and Integration Commission.
The magistrates had to travel from their stations to Nairobi on Thursday night following a notice from High Court Registrar Lydia Achode at 6pm on Thursday that their swearing in had been moved from Saturday.
The decision to change at the last minute came after MPs said it would be illegal for any public officer to take oath on Saturday when the Constitution provides that they should do so on the day the new law takes effect.
The initial plan was to have magistrates sworn in at seven stations; Nairobi, Mombasa, Nyeri, Nakuru, Meru, Kisumu and Kakamega.
