Procedural Posture

Judicial Review / Judgment on Originating Motion

  1. 1 Whether the Director of Public Prosecutions unlawfully failed to act on the Maai-Mahiu tragedy
  2. 2 Whether the police had completed or properly advanced investigations and an inquest
  3. 3 Whether the doctrines of exhaustion, ripeness, res judicata or sub judice barred the motion

Ratio Decidendi

The court held that the Maai-Mahiu tragedy was a matter of profound public importance, that the DPP had a constitutional role to direct investigations and was wrong to stand aside, and that the police ought to have pushed the matter to a proper investigative conclusion. The objections based on exhaustion, ripeness, res judicata and sub judice failed for lack of evidential foundation or because they were inapt to a criminal accountability complaint. The applicants therefore met the threshold for judicial review relief on the core prayers seeking investigation and prosecution action, and access to the report from Kenya Railways.

Court Disposition

Originating motion allowed in part; core prayers granted

Orders

  • Prayer 1 granted: declaration that failure by the 1st respondent to investigate or prefer charges violated fair administrative action and discriminated against the applicants and victims.
  • Prayer 2 granted: the 1st and 3rd respondents to collect evidence and prosecute the responsible persons within 30 days.
