Summary: written with AI from the case record.

What it's about
The petition concerned whether California could exercise personal jurisdiction over a nonresident defendant based on an interactive website accessible there and on the alleged effects of conduct not expressly aimed at California.
The dispute came from the Ninth Circuit and centered on whether an interactive website accessible in California could support a case against an out-of-state defendant.
Question presented
1. Whether the Due Process Clause of the Fourteenth Amendment prohibits a state from exercising personal jurisdiction over a nonresident defendant whose only contact with the forum state is an interactive website that is accessible in the forum state, but that does not target the forum state or its residents. 2. Whether the Due Process Clause of the Fourteenth Amendment prohibits a state from exercising personal jurisdiction over a nonresident defendant under the “effects test” of Calder v. Jones, 465 U.S. 783 (1984), where the defendant’s allegedly tortious conduct was not expressly aimed at the forum state.
