There really isn't, unless the phone records are put into evidence. Remember, disbarring is a much worse than a disqualificaiton.
You have one person weaseling, two (Wade and Willis) who agree on stuff but don't sound very honest, and one person who is calling them out. It's still a he said/she said. And the judge will have to deal with Willis for years if not a decade. There's still an open question about disqualification if the tie goes to the runner, etc.
Disbarring is a whole level above that. Yes, perjury would get you there, but you'd need more than "he said/she said" levels of proof. Hence again why the phone calls are important.
