Where can I find the papers of Cassiopea?

I am looking everywhere, but it is impossible. I have even contacted some prosecutors but nothing. How can I find the papers of the Cassiopea's trial?

It is very disappointing when you know there is a gold mine out there and you cannot access it. I will try to write the tribunal where they did the inquiry. Will they even just answer to my email? This is the issue we deal all days in doing our job..
