PART XVIII – VISITING FORCES
283. Prosecution and trial for civil offences
(1) The Kenyan civil courts shall have exclusive jurisdiction and primary right to try any member of a visiting force for any civil offence committed in contravention of any Kenyan law, customary international law, treaty or an agreement the Kenyan Government is party to.
(2) Despite subsection (1), a provision in a treaty or agreement to which the Kenyan Government is party to may confer exclusive and primary right to try any member of a visiting force to the authorities of that visiting force.
(3) If a member of a visiting force has been tried by a court of the country to which the force belongs—
(a) the member shall not be tried for the same offence by a Kenyan court; and
(b) if the member is subsequently convicted by a Kenyan court and it appears to that court that the conviction is wholly or partly in respect of acts or omissions in respect of which the person was convicted by the court, the Kenyan court in sentencing shall have regard to any sentence passed by the court.
