Maybe for once I agree with you about the resignation, but to be honest a trading halt isnt abnormal for the price fluctuations that we all saw and thats not abnormal as thats in place to protect investors as well, the pending quasi charge was however the likely cause of the caveat emptor simply based on that pending alone as anything pending is a cause for a caveat emptor, I'm surprised it took the sec that long to apply it, but it was likley the price that tripped the alarms and then the pending charge hence the thanks to the osc as you said.
