Hartford Fire Ins. Co. v. California

Background

A group of 19 States and private plaintiffs sued domestic insurance companies and foreign reinsurers, alleging that they conspired to change commercial general liability (CGL) insurance terms. The complaints say insurers and reinsurers pushed changes like moving from "occurrence" to "claims-made" triggers, adding retroactive dates, excluding pollution coverage, and capping legal defense costs, using the Insurance Services Office and threats to withhold reinsurance.

Reasoning

The core question was whether the McCarran-Ferguson Act (which generally leaves insurance regulation to states) shields the defendants from the Sherman Act, the federal antitrust law. The Court held most of the domestic defendants’ alleged conduct was not protected from antitrust liability, and it rejected the idea that merely conspiring with foreign reinsurers strips immunity. Importantly, the Court agreed that many complaints plausibly alleged coordinated refusals to deal or coercion (a "boycott" exception to immunity), so those claims could survive dismissal. On the foreign-defendant side, the Court found the London reinsurers’ actions had substantial effects in the United States and that international comity did not bar U.S. courts from hearing those claims because there was no true conflict with British law.

Real world impact

As a result, many antitrust claims by states and private parties can proceed against insurers and reinsurers. Plaintiffs may now pursue discovery and trial on allegations of coordinated pressure to change policy terms. Some rulings here resolve only early dismissal motions, so final outcomes will depend on further proceedings.

Dissents or concurrances

Justice Scalia disagreed about the extraterritorial reach and offered a different, narrower view of what counts as a "boycott," urging dismissal of the foreign-defendant claims. He and others filed separate opinions on parts of the reasoning.
