Let me get this straight - the cardinal doesn't even know what his attorneys are saying? Give me a break.
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.
