Folks, I strongly recommend that we not imply the use of violence against anyone, even in a joking manner.
Even if they could, wouldn't doing so mean that PGI, HBS, and IMR wouldn't have to be paying any legal fees during that time? Seems counterproductive as bleeding them has been a big part of HG's strategy.
Lawyers would still have to be retained and would incur expenses as they work on research and responses to whatever HG comes up with.
Emphasis mine, but there are no appeals after a DwithP. It's over, it's done, you cannot continue.
That is absolutely untrue. You can appeal a Dismissal with Prejudice. Since this is a Federal civil matter, you have precisely two appeals: one to the Appellate Court - who, as their name implies, deal primarily with appeals - and, if they rule against you, to the Supreme Court of the United States. (The rules for state courts and criminal cases are different, and off-topic here.)
What you cannot do, if the Dismissal with Prejudice is upheld, is ever sue on the same grounds again. So you're correct to an extent, but everyone does have the right to appeal before a ruling takes effect.
