I appreciate your concerns, but truly: I owe you nothing. It takes very little integrity to make an uninformed allegation and then sit back with a smug look and a mug full of selfrighteousness decrying “prove me wrong”.
Why don’t you prove Legal Eagle wrong? It would without a doubt be more fruitful because I’m not entertaining it.
Obviously I can’t possibly speak as to why they chose to do what they did. But I would assume that making a motion to dismiss due to the fact that arbitration has already been agreed to (seemingly unrelated from your perspective but from a legal perspective is really the only substantive aspect, so wildly related) is far less scandalous than making a motion to dismiss with no recourse for the plaintiff at all and would be far more damaging to their reputation.
And that DOES make sense.
