A Lone Pine order, named for a New Jersey toxic tort decision, requires each claimant to submit threshold evidentiary support, typically expert affidavits establishing exposure, a qualifying diagnosis, and a causal connection.
Failure to comply results in dismissal, often with prejudice.

Lone Pine, Prima Facie Showing Order
Why it Matters?
Lone Pine is the most effective tool for culling unsupportable claims from a large inventory, because it demands actual expert proof rather than the self-reported information a fact sheet collects. Courts vary in willingness to enter such orders and in timing, with many requiring that general causation be established first. Obtaining one after a favorable Daubert ruling is the strongest position, since claimants must then produce case-specific proof against a settled scientific framework.
