Dear Wolfgang, You might be surprised to learn that indeed unrecognized or missing proof of citizenship can be devastating, as for example in this commonly cited example: https://en.wikipedia.org/wiki/Mehran_Karimi_Nasseri This person was effectively without citizenship as they were unable to prove it due to missing documents. This illustrates what I was talking about previously. Legal is full of surprises like these and counter-intuitive twists. You can't use common-sense logic, say "I would be very surprised to learn" and expect that to have much meaning in a legal setting. Probably no one on this list is equipped to make strong predictions about legal outcomes, especially in a changing legal landscape. I commend the first reply for sourcing from a place that might provide some insight. Subsequent to that, all I can say, if we're software developers, please let's stick to software development and not pretend we're lawyers. I would hope the conversation going forward would stay clear of legal opinions unless they come from someone actively practicing law in copyright either in one of the big markets or international copyright, and that person can prove their active credentials. It would be much more constructive to talk about how to find a group of experts like this and how to fund their work. What I can bring to the table is my experience in choosing, directing, and working with legal counsel and knowing how to tell when dealing with good, or bad, counsel, which I have done multiple times in the past. Best regards, Damian
