That’s interesting because a corporation could place its headquarters in a very difficult jurisdiction for lawsuits, one that had a high hurdle and limitations on penalties for a plaintiff and strong protections and bars for a defendant. I wonder what the Justices were thinking. Have you read their decision?
We don’t want frivolous lawsuits, but we do want lawsuits with a firm foundation to go forward. I wonder if they shut the door too hard on this one. They are, after all, just human.
A corporation can still be sued in any state where it did something wrong (that's "specific jurisdiction"-- see my post #1 on this thread). That is usually enough to permit meritorious cases.
What this decision is about is "general jurisdiction"-- suing a corporation in State A for something it allegedly did in State [or country] B. SCOTUS said ages ago that such a suit could be brought in the corporation's "home" state, but a lot of states have interpreted that to mean "anywhere it does a lot of business." SCOTUS today said, no, a corporation only has one "home" (or possibly two-- the state of incorporation and the state where its headquarters are).
