So in essence your claim is that there were two types of forms that could been reported to Ratzinger in 81'; a report of misconduct, or just a request for time-off or psychiatric care. Ratzinger would not have investigated a request for psychiatric care. So we can expect the Vatican to produce the documents?
The diocesan court of canon law...
What's the makeup of this court?
I doubt it was a form - I'm sure it was a letter saying: "I'm recommending hospitalization for this troubled priest who's having a breakdown, please give me authorization to book him a hospital stay."
So we can expect the Vatican to produce the documents?
The documents are apparently out there already.
What's the makeup of this court?
Generally a panel of three or more canon lawyers - it's the usual kind of legal setup under the European code system. There is one judge, or in certain cases more than one, who reviews all the documents, evidence and pleadings and adjudicates. Similar in many ways to the way cases are argued before the Supreme Court.
I assume the question you're getting to is whether there is any external supervision by non-Church authorities. The answer is no.
