I guess the Org. have realised they were regularly getting their arses kicked in Court using their inept in-house Lawyers.
They need top notch guys for this, because it is bigger than merely losing the $$$ from the Norwegian Government. This Judgement in favour of the Government challenges their Policy of Shunning, that they cannot afford to lose a grip on, it is their CHIEF means of Control.
Admittedly, Norway is not a huge deal in the World of International Law usually, but this matter concerns Human Rights. This time the world of Law will watch with interest, analyse the arguments, and the outcome. Interesting times !
