I'm unaware of what the judge knows, but it's doubtful it would have gotten to his attention this quickly. I am aware, however, that the palintiffs and their attorneys are cognizant of it and are following up.
Interestingly, despite this letter, I have been told by a few current HLA parents that as soon as they get their kids out - they are waiting until the end of the academic year - they will also be signing up to the class action suit or retaining private counsel to pursue issues they describe as "fraud." Some related that they are "afraid" to speak up until their kids are home for fear of "retaliation" against them or their children.
This email, in my opinion, will become entered into evidence in the class case and/or other individual suits.
