I would bet that for a government agency, merely calling that "fraud" in any public communication is highly illegal. They are the government, and they cannot make such statements about individuals or individual businesses, they can only file a legal complaint, and the point out they've done so, nothing more. I can claim someone comitted fraud, you can (still risky though, but not per se illegal, only illegal if you do it to damage the other person in any way, not if you merely genuinly think they committed fraud), but they can't (not even if there's zero damage). Not allowed. So sue them. They deserve it.
