Understood.

One thing alot of people do not know about this country is that members of congress are exempt from all kinds of conflict of interest and insider trading regulations. They can, by legislation, make or break a company or industry and freely trade in it, totally indemnified from any action of the SEC or anyone else.

So I wouldn't be surprised if alot of these suits were vexatious. Politicians here are lawyers, so what do you expect ?

There is the ability to countersue for "frivolous lawsuit" but this vexatious thing seems to hit the nail more on the head, preventing the court system from being abused for personal gain.
