The Seventh Circuit Explains the “Co-Conspiracy Exception” to the Illinois Brick Rule in Healthcare Antitrust Lawsuit

Jarod Bona, The Antitrust Attorney
Antitrust law evolves in such a way that opinions from federal appellate courts are always interesting in how they affect the doctrine. But there are a select few judges who earn even closer attention when they write an antitrust opinion. Judge Diane P. Wood of the United States Court of Appeals for the Seventh Circuit is one of those judges.
In Marion Healthcare, LLC v. Becton Dickinson & Company, the Seventh Circuit, through Judge Wood’s opinion, effectively articulates the co-conspiracy exception to the Illinois Brick rule. The opinion is significant not because it marks a departure in the prevailing law, but because it explains it so well. This is an example of an opinion that courts and attorneys will likely cite in the future when this issue comes up.
