What it's about

AstraZeneca, Eli Lilly, Novo Nordisk, and Sanofi ask the Supreme Court to review a Second Circuit antitrust case brought by health-care providers. The dispute concerns whether the providers may seek lost-profit damages tied to purchases or sales they say did not occur because of an alleged drug-pricing conspiracy, and whether allegations of joint lobbying and trade-association participation plausibly show an agreement to conspire.

Question presented

1. Whether Illinois Brick Co. v. Illinois, 431 U.S. 720 (1977), which bars antitrust claims by indirect purchasers and sellers, applies to a claim of “lost profit” damages based on indirect purchases or sales that were not made due to the alleged conspiracy? 2. Whether the allegation that businesses had an “opportunity to conspire,” such as through joint lobbying and participation in a trade association, plausibly suggests an antitrust conspiracy?

Briefing

What it's about

Drug companies AstraZeneca and Eli Lilly ask the Supreme Court to review a Second Circuit antitrust case involving claimed lost profits and alleged coordination among businesses. The petition raises questions about suits based on indirect sales and whether lobbying or trade-association activity can plausibly suggest a conspiracy.

Argument

The case is pending, and oral argument has not been scheduled. No substantive justice or advocate reactions are available yet.

Impact

The case could affect when businesses may seek antitrust damages for profits they say they lost from sales that never occurred. For example, a company claiming it lost customers because of an alleged drug-industry conspiracy could face limits on its ability to sue.

What's next

The Court may decide whether to grant certiorari (the Court's decision to hear the case). No argument date or decision window is available; watch for a scheduling order or other Court action.
