What principle did Daimler AG v. Bauman reaffirm regarding general jurisdiction?

The principle reaffirmed by the Supreme Court in Daimler AG v. Bauman is that a corporation must be "at home" in the forum state for general jurisdiction to be established. This case clarified the standard for determining when a corporation is considered to have sufficient connections to a state, which, according to the ruling, typically requires that the corporation's affiliations with the state are so continuous and systematic that the corporation is essentially at home there.

In practical terms, this means that jurisdictions where a corporation has its principal place of business or where it is incorporated are the primary locations deemed appropriate for general jurisdiction. This ruling effectively limits the reach of general jurisdiction to ensure that corporations are not subject to being hailed into court in any jurisdiction based on minimal contacts, thereby providing more clarity and predictability for businesses regarding where they can be sued.

This ruling underscores the importance of a corporation's local presence in determining jurisdiction, reinforcing the notion that mere business activity or transactions in a forum state do not suffice to establish general jurisdiction.
