"SEC certainly didn't get their answer from DECN as noone from DECN was contacted."
You didn't learn that from the SEC. So where did you learn it? From a message board post? The guy who says he popped in on Berman purportedly said this: "He did mention at some point that the SEC had contacted him before on a few occasions but he was surprised regarding today's suspension."
But it doesn't matter. "The SEC may suspend trading in a stock when the Commission is of the opinion that a suspension is required to protect investors and the public interest."
That's all it takes for a suspension, like it or not...the opinion of the Commission that a suspension is required to protect investors and the public interest.
