The Kes 122 million fraud case against Kakamega deputy governor Ayub Savula and 29 others is set to commence today.
The case is being heard at Milimani Law Courts by the Milimani chief magistrate Wendy Micheni.
Further, two more witnesses from the advertisement office have testified in the matter after the death of a key witness who was murdered last year.
Savula and former PS Sammy Itemere suffered a blow in November last year after the court declined to expunge evidence of the slain key witness Jennifer Wambua.
Micheni, in her ruling, said that there was no particular provision to expunge evidence that was lawfully and procedurally admitted to court.
"The evidence of the witness is admissible in court even though the weight may be slight," she said.
The ruling came after the defense team asked the court to exclude the evidence of Wambua, arguing that her evidence had not been cross-examined.
Savula and former Ministry of Information PS Sammy Itemere, and 28 others are charged with stealing Kes 122.3 million from the Government Advertising Agency (GAA).
