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.
