It simple. A non-event if you will.
Uhuru is required to be present when ANY CRITICAL decision or event is going on. Uhuru has to be there to hear verbatim or to guide his lawyer or even fire them...and defend himself solo
Crucial events including start of trial, sentencing, witness testimony of crucial witnesses...those Uhuru has to be physically present.
Critical decision...is whether to adjourn indefinitely or not. That will affect Uhuru's right to expeditious trial..if granted Uhuru will remain an ICC accused person indefinitely. Uhuru has have a say if he wants.
