eurocan, with all respect, we are not talking here about what went wrong in the cockpit. This has been discussed exteeensively elsewhere.
The question that has come up now is who can, and under which circumstances, legally control airspace in Germany, or Europe for that matter. It seems it was the court´s conviction that it was illegal for a non-governmental and non-German institution to control German airspace. The relevant contracts with Skyguide did not meet German constitutional law, and the management of German airspace would have had to remain under governmental supervision, which was not the case. Therefore, so the ruling, the German government shall be liable to cover all (!) claims for damages.
This, of course, may well open a can of worms...
