Another thing with the trial I was a jury member on was the plaintiff themselves were not always present, most days it was just their lawyer and paralegal. The judge reminded us each day that we can’t hold their physical presence or lack thereof for or against them.
I’m no lawyer, but if neither the plaintiff nor the witnesses needed to be physically present I don’t see how they can justify forcing Gabe Newell to be. Despite being CEO he’s still not the defendant.
