There must be someone else who is in a better position to explain, but the following is what I think it means, putting it in context.
The case itself is ongoing, and still has not reached trial. The contempt order that the Borg pay $4000 per day was an interlocutory order, relating to the pre-trial releasing of the borg’s internal documents to the plaintiff for inspection. The Borg refused to provide a document or documents unredacted, and so the court issued an order that the Borg $4000 per day, until the document is provided.
As everyone knows, the Borg appealed and lost. The $4000 per day stands. Perhaps there is an argument that the fine is suspended for the period of the appeal; I don’t know. In any event, it is a big fine.
Now that the matter has been returned to the trial court, the pre-trial steps will continue. In parallel with that, the plaintiff can seek to enforce the $4000/day order. The plaintiff would not have to wait until the conclusion of the case to do that. The plaintiff can enforce, as of today.
The process of enforcement varies from place to place. I have no idea what the process is in California, but most places, when it gets to this stage, it is fairly quick, and can lead to a physical seizure of assets, a winding up, or the appointment of an external administrator, if the amount is still not paid.
So basically, the Borg has to pay the fine, and the case rolls on. I would expect the Borg will just pay a very large amount of money to confidentially settle the case, now.
