On your point 3) If I can remember correctly from my law lectures, "judgments" are reserved exclusively for the legal usage (courts, tribunals etc). There is only one correct spelling of "judgment" in the legal sense, everywhere else gives a judgement as to their opinion on a matter, the difference being, that if someone passes a judgment then you know it has come from a legally binding court of law.

I would regularly get a red pen marker through my essays if I used the wrong version (so you quickly get things like this drilled into you). If it's written with the "e" version on justice.gov.uk then they are either using it wrong, or they are using the non legal version (ie "In my judgement this painting looks like a fake", compared to, "In the courts judgment, the painting was a held to be a forgery").

It might seem pedantic, but I guess that's the way law is. For instance, court and Court (when used legally) also mean and can refer to two different things.

On point 2) Do you think that Apple made it clear that the court ruled in favour of Samsung? One line was given to this, whereas 20+ was given to why Apple feel that this judgment was a mistake? I've updated my original comment anyway.

(I agree that they didn't have to include the link for other countries as per your first point).
