The Anti-Corruption Court has allowed the Ethics and Anti-Corruption Commission (EACC) to investigate afresh former Transport Cabinet Secretary Michael Kamau.
Kamau is alleged abuse of office and flouting of tender rules during his tenure.
Justice Hedwig Ongudi declined to allow his application to be acquitted.
He ruled that Kamau's appeal before the Appellate Court was allowed on a technical ground that EACC was not properly constituted at the time investigations were completed.
“It was not based on the manner the investigations were carried out or the innocence of Mr Kamau. That is why the Court of Appeal did not get into the substance of the investigations undertaken by the EACC,” ruled Justice Ongudi.
