The Middelburg Specialised Commercial Crimes Court on Tuesday struck the case against former Eskom boss Matshela Koko and others from the roll.

The court found that there had been unreasonable delays in the R2.2-billion corruption case against Koko and his co-accused.

This, however, is not a pronouncement of the innocence or guilt of the accused. The matter can be re-enrolled at a later stage.

Koko was accused of being "at the centre of a corrupt scheme" which sought to help Swiss engineering firm ABB secure a lucrative R2.2-billion contract at the Kusile Power Station in Mpumalanga. 

With Koko allegedly wielding his influence at the power parastatal to swing the contract in their favour, an elaborate network of actors received kickbacks, and millions were ploughed into companies connected to his daughters.
