I'm not Serenster, but my husband is a litigator and has had many an embargoed judgment. The point of the embargo is to allow the parties to deal with any ancillary matters before the judgment is made public - not to dispute the substantive judgment or ask for substantive changes. This can range from minor things like typos; to requests for ancillary orders if there judgment might have a knock on effect, eg if there is a related piece of litigation or something else needs to happen in the case as a result of the judgment to bring it to a conclusion or to the next step. Also, the parties may want to ask the judge to make an order for how costs will be dealt with. And I suppose in sensitive/high profile cases like this, giving the parties a chance to digest the judgment before being confronted with the press.
Funny people are talking about Harry's face. My husband is very, very strict about what he lets me know about his work and certainly he would get into massive trouble if he shared something like an embargoed judgment with me. I have to guess from his face how it's gone!
I'm now wondering if all the HRH controversy is some sort of clapback following a negative outcome for Harry. A sort of reminder of their status.
Anyway, even if Harry's won, all he has won is a re-run of the decision making process about his security, with no guarantee that the outcome will be any different to what it has been up until now.
