Leveraging Lone Pine: Using Case Management Orders to Cull Meritless PFAS Claims

publication | September 12, 2025

A recent article by a Hollingsworth LLP partner Carter F. Thurman examines how courts have turned to Lone Pine orders to manage complex PFAS litigation. These case management tools, rooted in Rule 11 principles, require plaintiffs to provide early evidence of injury, exposure, and causation before proceeding to costly discovery. Highlighting the decision in Conklin v. Corteva, the article explains how the court required plaintiffs to submit expert declarations and found that Lone Pine orders are appropriate even in smaller cases. The article underscores how Lone Pine orders can efficiently streamline litigation and reduce meritless claims.
