So how far does sovereign immunity extend in Kiwiland, then? Can he drag her into court for defamation, or is he just stuck making nasty faces at her in the papers? That is, she may be right in a sense - if she can't be sued for such a thing, she can't be held legally responsible.
Of course, asserting sovereign immunity, even if the law allows it, is likely to be a political nightmare - it tends to have bit too much of that droit du seigneur feel for many people.
,,, as of a couple of weeks ago it seemed not far enough. Her staff advised she would be out of the country when the Court case came up - at that stage no date had been set LOL!!
