I don't think so. The Covenant Not To Sue in the rulebook stretches 2-1/2 pages and calls out both suits against the organization and against the officials.
FWIW, I've been involved in one of the more suit-happy industries out there for a number of years, and yet I must say, the volume of legal stuff in the rulebook is pretty astounding. The entirety of Section 1, from page 15 through page 39 is nothing but legal disclaimers and rule violation and appeal procedures. Sheessh...
In any case, even if someone sued Tom and Graham, I'm quite sure they have Directors and Officers insurance in place that would cover not only the legal costs but any loss they would suffer. That means they wouldn't pay a personal price for their actions.
