Many thanks to Section 2 class member Kaneily Alfaro for sharing this with me.
P.S., out of an abundance of professorial nerdiness, I’ll note my disagreement with the video’s characterization of the case. The only matter on which the Court was unanimous was on the judgment. The Court disagreed quite vehemently regarding the legal justification for tag jurisdiction. Brennan’s preference for the minimum contacts test makes it possible that tag jurisdiction is not always guaranteed.
