AstraZeneca Pharmaceuticals LP, et al. v. Mosaic Health, Inc., et al.
Paid petition · United States Court of Appeals for the Second Circuit, No. 24-598 · judgment August 6, 2025
(petition-stage, structural)
Modestly above the 4.1% base rate. The model weights this up for counsel who has won certiorari before, a Second Circuit decision below, and a business petitioner, and down for a business respondent.
Questions presented
This case presents two important antitrust questions that have divided the courts of appeals:
-
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.
-
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.
