Methods to Reduce Nonmeritorious Suits in an MDL

The presence of nonmeritorious lawsuits in MDLs imposes unnecessary burdens on the court, leadership counsel, and the parties.  The presence of nonmeritorious claims also threatens to undermine the public’s perception of the MDL process more generally.

Filtering out nonmeritorious suits at an appropriate stage of the litigation is an important function of an MDL court, both to effectively manage the MDL itself and to ensure that cases remanded from the MDL present legitimate disputes for transferor courts to resolve. Certain circumstances generate a special need for increased scrutiny, including where plaintiffs’ injuries are difficult to verify, causation or exposure is contestable, and claim volumes are high. See Nora Freeman Engstrom, The Lessons of Lone Pine, 129 Yale L.J. 2, 33 (2019). Equally important, however, is ensuring that efforts to weed out nonmeritorious claims do not lead to unfair or counterproductive results, such as unduly burdening individual plaintiffs or improperly dismissing legitimate claims.   

Three common tools that MDL courts use to identify and address nonmeritorious lawsuits are: (1) initial case census forms, (2) plaintiff fact sheets, and (3) Lone Pine orders.

Initial case census forms seek foundational data on filed and unfiled cases in the MDL. These forms are typically standardized and brief, often seeking basic information about product usage and injury. Such information can be helpful not only in identifying those plaintiffs who are unable to provide essential information to substantiate their claims, but also in ensuring that MDL leadership and bellwether trials are adequately representative.

Plaintiff fact sheets are standardized court-approved forms that seek a broader set of information. Fact sheets require individual plaintiffs to submit information (typically under oath) about their background, injury, past claims for compensation, and, where relevant, the identity of prescribing and diagnosing physicians and other healthcare providers. As with Lone Pine orders described below, failure to complete the fact sheet may (though does not always) lead to dismissal without prejudice. Scholars generally agree that fact sheets, when used appropriately, have benefits—for example, aiding in the selection of bellwether cases. See Nora Freeman Engstom & Todd Venook, Harnessing Common Benefit Fees to Promote MDL Integrity, 101 Tex. L. Rev. 1623 (2023). But some have also expressed concerns about the burden particularly bloated fact sheets may place on plaintiffs. See, e.g., Margaret S. Williams et al., Fed. Jud. Ctr., Plaintiff Fact Sheets in Multidistrict Proceedings: A Guide for Transferee Judges 7 (2019). Understanding these risks and benefits is increasingly significant as the role of fact sheets in MDLs continues to evolve.

Lone Pine orders require claimants to come forward with prima facie injury, exposure, and specific causation evidence by a specified date—or face dismissal.  Lone Pine orders differ from plaintiff fact sheets in that Lone Pine orders require a claimant to provide evidentiary support, such as an affidavit from a physician, establishing their injury. Lone Pine orders have been issued both prior to and after discovery. Such orders aim to expedite plaintiff-side discovery, identify plaintiffs with meritless claims, and streamline the ensuing litigation by removing them, permitting the parties and the court to focus their attention and limited resources on disputed claims supported by at least some evidence. But while many believe that Lone Pine orders streamline and expedite complicated MDLs, some courts and scholars assert that they can be inconsistently applied and circumvent key procedural safeguards. See generally Engstrom, supra. Further, these orders may be more labor-intensive and expensive to complete than initial case census forms or plaintiff fact sheets, as they often require evidence of specific causation and supporting testimony from qualified experts. Perhaps unsurprisingly, some courts believe that Lone Pine orders are an “extraordinary procedure” that should only be used when all other protections have been exhausted.  Id. at 39–40.

The below sections discuss these three tools and many of the unique questions and issues they present.
