--- title: "Asahi Metal Industry Co. v. Superior Court of California" type: Landmark Case source: https://casebriefly.com/landmark-cases/asahi-metal-v-superior-court --- # Asahi Metal Industry Co. v. Superior Court of California Asahi produced a fractured Court on the stream of commerce theory of personal jurisdiction but established that the exercise of jurisdiction must satisfy a reasonableness analysis even if minimum contacts exist. The case created a lasting split between Justice O'Connor's 'stream of commerce plus' test (requiring additional conduct directed at the forum) and Justice Brennan's pure stream of commerce test (placement into the stream is sufficient). ## Citation 480 U.S. 102 (1987) ## Year 1987 ## Court Supreme Court of the United States ## Facts Gary Zurcher was injured in a motorcycle accident in California allegedly caused by a defective tire tube. Zurcher sued Cheng Shin, the Taiwanese manufacturer of the tube, in California state court. Cheng Shin filed a cross-complaint for indemnification against Asahi Metal, a Japanese company that manufactured the tire tube's valve assembly. Asahi's valve assemblies were sold to Cheng Shin in Taiwan, and some of the finished tubes containing those valves eventually reached California through the stream of commerce. ## Procedural History The California Superior Court denied Asahi's motion to quash service for lack of jurisdiction. The California Court of Appeal reversed, but the California Supreme Court reversed again, finding jurisdiction proper. The U.S. Supreme Court granted certiorari. ## Issue Whether a California court could exercise personal jurisdiction over a Japanese component-parts manufacturer whose products reached California through the stream of commerce, in a cross-claim for indemnification filed by another foreign manufacturer. ## Holding The Supreme Court unanimously held that the exercise of jurisdiction over Asahi would be unreasonable and therefore violated due process. However, the Court split 4-4 on whether Asahi's placement of products into the stream of commerce, without more, established minimum contacts with California. ## Reasoning Justice O'Connor, writing for a plurality of four, argued that mere awareness that a product might reach the forum through the stream of commerce is not enough; the defendant must take additional actions directed at the forum state, such as designing the product for the forum market, advertising there, or establishing channels for providing advice to customers there. Justice Brennan's concurrence, joined by three others, argued that placing goods into the stream of commerce with awareness that they would reach the forum is sufficient for minimum contacts. All eight participating Justices agreed, however, that exercising jurisdiction over Asahi would be unreasonable given the heavy burden on a foreign defendant, the slight interest of the forum state (the original plaintiff had settled), and the international implications. ## Impact Asahi created an enduring circuit split on the stream of commerce theory that persisted for decades. Lower courts divided between O'Connor's 'stream of commerce plus' approach and Brennan's pure stream of commerce test. The case also reinforced that the reasonableness prong of the jurisdictional analysis can independently defeat jurisdiction even where minimum contacts arguably exist. The Court partially addressed this split in J. McIntyre Machinery v. Nicastro (2011), though that case also produced a fractured opinion. ## Key Quotes - The placement of a product into the stream of commerce, without more, is not an act of the defendant purposefully directed toward the forum State. - The unique burdens placed upon one who must defend oneself in a foreign legal system should have significant weight in assessing the reasonableness of stretching the long arm of personal jurisdiction over national borders. - A consideration of these factors in the present case clearly reveals the unreasonableness of the assertion of jurisdiction over Asahi. ## Related Cases - world-wide-volkswagen-v-woodson - international-shoe-v-washington - bristol-myers-squibb-v-superior-court - ford-motor-co-v-montana ## Exam Relevance Asahi is heavily tested in civil procedure exams, especially in questions involving component-part manufacturers and stream of commerce scenarios. Students must know the difference between the O'Connor and Brennan approaches and be able to apply both. Exam questions often ask students to argue both sides of a stream of commerce jurisdictional question and analyze whether the reasonableness factors independently support or defeat jurisdiction. ## Study Tips - Know both the O'Connor 'stream of commerce plus' test and the Brennan 'pure stream of commerce' test cold. Be able to state which justices joined each opinion. - Remember that even though the Court was split on minimum contacts, it was unanimous that exercising jurisdiction was unreasonable under the fairness factors. - Practice applying the five reasonableness factors from World-Wide Volkswagen to fact patterns, as Asahi demonstrates they can be independently dispositive. - Connect Asahi forward to J. McIntyre Machinery v. Nicastro (2011), which revisited but did not fully resolve the stream of commerce split. ## Doctrine Established Stream of Commerce Plus Test --- Source: [Asahi Metal Industry Co. v.
