This is the last response I am going to post, because there are more important topics to discuss on the thread. I understand that you are keen to reassure people that nobody can interfere with the judgment, and this is correct. The barristers or advocates (whether they are KCs or not) see a draft of the final judgment when the judges consider it to be finished. They can draw the judges' attention to errors in the draft, which the judges may choose to correct. That does not extend to changing the decision.
If you are still in any doubt, please see paragraph 10 of this very recent High Court decision from Hayden J:
https://www.bailii.org/cgi-bin/format.cgi?doc=/ew/cases/EWHC/Fam/2025/638.html&query=.2025.+EWHC+638+(Fam)
where Mr Justice Hayden says this:
"It must be said that times have changed since the above judgment was delivered, particularly post-pandemic, where many, I suspect most, judgments are now handed down electronically. In this process, which usually involves a draft judgment being sent to the parties for corrections, amendments, anonymisation and compliance with Transparency Orders, the date that the decision is formally handed down can sometimes get lost. I suspect that compliance with the Rules may frequently be "overlooked"."
