Last week, the court in In re: Fosamax Products Liability Litigation granted Defendant Merck & Co.’s motion for a Lone Pine order. No. 06 MD 1789 (S.D.N.Y. Nov. 20, 2012). Lone Pine orders are valuable tools in defending mass tort and product liability litigation, forcing each plaintiff to demonstrate evidence of scientific proof of their claim before their claim is allowed to progress.

Lone Pine orders originate from a 1986 New Jersey state court case, Lore v. Lone Pine Corporation, No. L-33606-85 (N.J. Sup. Ct. Law Div.) . There, the court issued a case management order requiring plaintiffs to provide expert reports supporting a causal link between their claimed injuries and exposure to defendant’s landfill. See Lone Pine Corp., No. L-33606-85, 1986 WL 637507 (N.J. Sup. Ct. Law Div. Nov. 18, 1986) (dismissing plaintiffs’ cases where they had failed to provide adequate expert evidence for their claims).
