The Courts already have mechanisms to limit "unlimited" subpoenas or requests for discovery. Requests for the software source code or similar, bug reports, and other reports of issues are or would largely not be unreasonable where the key issue is reported thievery, fraud, and mismatched data based on software as the basis for the allegations and prosecution.

They do, but applications on these matters can easily overwhelm the financially weaker opponent. Interesting comment in one of the Post Office judgements:

"10. Finally, disclosure is very expensive. The court will be astute to guard against it becoming either satellite litigation or a weapon in the interlocutory arsenal."
