- 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?

Argument

Impact
