Delivering her judgment by fiat on Friday, Justice Rita Ofili-Ajumogobia found Omatseye guilty of 24 out of the 27 counts brought against him.
The Judge, however, discharged and acquitted him of three out of the 27 counts bordering on bid rigging.
Ofili-Ajumogobia found Omatseye guilty of awarding contracts above the stipulated threshold and convicted him on counts one to 20, 24, 25, 26 and 27.
