If there was no mediation... then the question is why there was a failure to perform the court directed task. Will be interesting to see what the judge has to say about it... maybe in a range from "nothing" to a "re-tasking under court supervision" with a more directive set of performance requirements... to a contempt citation ?
On the motion to disqualify, yours is incorrect. If Williamson is disqualified, so are all the members of his firm... according to the rules.
I think it is likely that Williamson and some members of his firm are going to have bigger problems to deal with in the future, than "just" the element of being disqualified from the current case. The problem isn't "just" that in the result of Williamson taking an interest in the subject of the case, which crosses lines in "the rules" that should disqualify him and his firm. It is instead that the rules there are do exist for reasons, so that crossing the lines in things the "rules" prohibit includes the risk that not just "the rules" have been violated. Those "reasons" that the rule exists might prove to matter a lot more than the fact of a "technical" violation of local rules.
There is also the perhaps too obvious element of the already known potential... in having the violations of the rules they've undertaken... result in structuring in an inherent conflict between Daic and Williamson. Daic might try to claim, later, that without his awareness he was being misrepresented... while just doing what his attorneys told him to do. That might even be true to some extent in terms of the choices made in the past by team Daic/Williamson... or, true at least in terms of it being their intent and the purposeful result of their prior effort, intending to enable at least the appearance that was true.
Still, with Daic having taken Williamson on as his business partner, and in the context of the current case, those are things that are their problem and their responsibility... in terms of the exercise of their choices within their partnership... which doesn't mean CLYW should allow any of the frauds they are practicing on each other to be imposed on CLYW, and the court, as part of an effort in perpetuating a serial fraud on the courts that may be designed to poison any result that might be produced.
