In the US, the golden rule applies. He with the gold makes the rules.
Quite true, but luckily for Kim he's spending his time and money in New Zealand courts. Also luckily for Kim, New Zealand judges tend to be a pretty independent lot, and while I'm sure the US is putting huge pressure on the New Zealand Government, the judiciary here are quite capable of telling the Government to mind their own business.
As an aside, I have seen this in person. At a social function years ago, a District Court judge (I think, certainly a judge of one type or another) called the former Prime Minister who was also a guest a "backstabbing cunt" and threatened to break his nose.
They were seperated and the judge was poured into a taxi. No-one seemed to know what the fight was about, but there was a fair bit of anger involved.
