I've worked for years as a legal secretary and paralegal in litigation. The only clients who ever wanted to see or have input into court filings were attorneys themselves. (Obviously, for affidavits, answers to interrogatories, client input is essential; but this was apparently an answer to a complaint.) Some attorneys send copies to the client of anything filed; some don't.
I would hope the cardinal would take the attorney to task, but I don't hold out much hope.
If Law were against what his attorney said, wouldn't he have fired the attorney?
