it is about the judgement about the publishing of an article in PM, which revealed NC and her son. PA sued PM and Bunte, in France the judge agreed with him, in Germany they refused it. From what I hear PM will try and drag to EU courts, since they did not spread rumours, but reported the truth and had valid proof. And they claim that since his fathers death he is head of state of a heriditery monarchy and thus an illigitemate child is not part of his privat life, but of public interest.
I haven't read the article, only the bit on the net, but basically what you said was correct. They only added that other countries are shocked and worried by the judges ruling.
Personally I will never understand why he sued in the first place, since whatever the outcome, it gives them and all other journals, mags etc a reason to reprint the whole story. So what's the point. It doesn't go away and the only winners are the lawyers involved. Might as well live with it and try not to do things that you don't want to read about the next day in the first place.
