What it's about

The Supreme Court overturned New Jersey’s ruling; six justices agreed the state could not hear Nicastro’s case against J. McIntyre, but only four said the company had not acted there to benefit from its laws.

The machine that injured Nicastro was a scrap-metal machine made in Great Britain.

J. McIntyre was a British manufacturer that sold its machines in the United States through an independent distributor.

Question presented

May a consumer sue a foreign manufacturer in state court over a product that the foreign company marketed and sold in the United States?

What the Court decided

Holding

The judgment is reversed. 201 N. J. 48, 987 A. 2d 575, reversed. JUSTICE KENNEDY, joined by THE CHIEF JUSTICE, JUSTICE SCALIA, and JUSTICE THOMAS, concluded that because J. McIntyre never en - gaged in any activities in New Jersey that revealed an intent to invoke or benefit from the protection of the State’s laws, New Jersey is without power to adjudge the company’s rights and liabilities, and its exercise of jurisdiction would violate due process.

Result
Reversed

The Court's reasoning

Justice Kennedy and three other justices said New Jersey could not hear the case because McIntyre had done nothing in the state showing it meant to benefit from New Jersey's laws. Justices Breyer and Alito agreed on the outcome based on existing decisions and these facts, without adopting a broad new rule.

— Justice Ginsburg(dissent)
