Minimum Contacts

Minimum contacts is the constitutional standard for personal jurisdiction established in International Shoe Co. v. Washington (1945). The Due Process Clause of the Fourteenth Amendment requires that a non-resident defendant have "certain minimum contacts" with the forum state "such that maintenance of the suit does not offend traditional notions of fair play and substantial justice."

The framework distinguishes between general and specific jurisdiction. General jurisdiction exists when the defendant's contacts with the forum are so "continuous and systematic" that they render the defendant "essentially at home" there. For individuals, this is their domicile. For corporations, after Daimler AG v. Bauman (2014), general jurisdiction is limited to the state of incorporation and the principal place of business (with a possible exception for extraordinary cases).

Specific jurisdiction exists when the lawsuit arises out of or relates to the defendant's contacts with the forum. It requires purposeful availment — the defendant must have deliberately reached out to the forum state and created contacts there. The unilateral activity of the plaintiff or a third party cannot establish minimum contacts. World-Wide Volkswagen v. Woodson (1980) held that foreseeability that a product will end up in the forum is insufficient — the defendant must purposefully avail itself of the forum's market.

Once minimum contacts are established, courts consider the "fair play and substantial justice" factors from Burger King v. Rudzewicz (1985): the burden on the defendant, the forum state's interest, the plaintiff's interest in obtaining relief, the interstate judicial system's interest in efficient resolution, and the shared interest of the states in furthering social policies. In rare cases, these factors may defeat jurisdiction even when minimum contacts exist, or support jurisdiction when contacts are borderline.

Recent developments include Bristol-Myers Squibb Co. v. Superior Court (2017), which limited specific jurisdiction to claims that arise from or closely relate to the defendant's forum contacts, and Ford Motor Co. v. Montana Eighth Judicial District Court (2021), which held that specific jurisdiction does not require strict causation between the forum contacts and the claim.

On civ pro exams, personal jurisdiction is one of the most tested topics. Students must systematically analyze general and specific jurisdiction, purposeful availment, and the reasonableness factors.
