What is "tag jurisdiction"?

Tag jurisdiction refers to a legal principle that allows a court to assert personal jurisdiction over an individual based on their physical presence in the state at the time they are served with legal process. This means that even if the individual is a non-resident and may not have sufficient contacts or ties to the state in general, their mere presence in the state for service of process can give the court authority over them. This principle stems from the notion that a defendant should be subject to the jurisdiction of the state where they are physically located when they are properly served with legal papers.

In contrast, the other options describe different contexts of jurisdiction that do not align with the concept of tag jurisdiction. Casual business transactions alone do not establish jurisdiction unless they meet certain criteria related to the defendant's minimum contacts with the state. Similarly, online activity does not automatically confer jurisdiction based on someone's physical presence; it depends on the nature and extent of the online engagement with the state's market or consumers. Finally, while jurisdiction may apply to corporate entities, tag jurisdiction specifically pertains to individuals, not corporations.
