@SunbathingDragon - I'm not sure if it will be early September. I've seen that predicted in the press but I don't know the source for that. I can't see anything in the transcripts to suggest the judge has given a predicted date. It will appear when the judge is ready.
The process from here is that the judge writes a draft judgement and sends it to the lawyers for each side. They can point out any typographical errors, factual errors or omissions but they must not tell their clients (or anyone else) anything about the judgement at this stage. The draft gives the lawyers a chance to prepare any applications they may want to make arising from the judgement. It is also normal for the judge to ask the lawyers to draft any orders that need to be made to put the judgement into effect.
The lawyers will inform their clients of the substance of the judgement about an hour before it is handed down. The judgement is handed down in a brief court hearing. The judge will not read it in full but will hear any applications. It is possible the losers will apply for permission to appeal, for example. Permission will almost certainly be refused but they can then apply to the Court of Appeal for leave to appeal.
Some think that ngn don’t care if they win or lose as I understand damages are capped at a relatively £325k?
Yes, the current ceiling for libel damages is around £300k-£325k. Given the serious nature of the allegations and The Sun's behaviour I wouldn't be surprised if damages are close to the ceiling. But I agree that, even if Depp receives the maximum, it is unlikely to worry NGN unduly.
