Anyways, the judge has made is very clear that the evidence against them is very strong, that the record is very strong, and that so far neither Uber nor Levandowski have denied that he stole the 14 000 documents.
IANAL, so I might be way off base.
A trial like this is not a single giant evidence dump followed by a giant decision. It is a series of hearings. After each hearing something can be ruled on. You can issue a subpoena to collect more information about A, we have settled B as a fact, you are misreading the law so you have to drop that line of inquiry, etc.
Each hearing is impartial. But impartial decisions come at many points. In fact some points will be appealed to a higher court which will make a ruling and then send it to a lower court again with instructions about how to proceed.
This sort of thing can take years.
This has been going on for a fair amount of time, the judge has reproached Uber more than once, a lot of evidence has been submitted. It appears that the judge has decided that, at this point, there's enough evidence to say that it's a fact that he stole the documents. They had a chance to challenge the [apparently overwhelming] evidence Google has, and they failed [apparently, also overwhelmingly].
