"info provided ... marked as confidential by one of the parties"
At least this is consistent with the rest of ICANN's "investigation": take the party's word for it without any further question.
We'd all like to face such empty "justice", where anything that reveals us as corrupt shits can simply be deemed "confidential" at our own behest. I guess that if my business model includes taking bribes then this would be "commercially confidential" and so forever safe from public scrutiny?
