Probably already posted, but don't have time to wade through 20 pages at this moment:
SEC Sues Elon Musk for Fraud, Seeks Removal From Tesla
What I find interesting here is that SEC offered a settlement, which Elon refused, hence the action.
So either a) the settlement was unacceptable or b) Elon is innocent of the charge - I believe the latter, but we still need to be dragged though this.
Very clever by the shorts to manipulate the SEC to do this at this moment, they were about to get burned badly - could still happen.
My take/guess: They went through the negotiations, got an ok-ish deal but in the process they realized that the SEC really doesn´t have a solid case at all. I hope Elon made the decision to decline it in agreement with his legal council.
