Pennsylvania's Fair Share Act After a Decade: How the 60% Threshold Has Shaped Multi-Party Defense

Pennsylvania's Fair Share Act, enacted in 2011 as amendments to 42 Pa.C.S. § 7102, restructured the state's tort liability framework. More than a decade later, the Act has produced a body of trial and appellate authority that shapes how defense counsel approach multi-party litigation. The Act's most distinctive feature is the 60% threshold for joint and several liability under § 7102(a.1)(3)(iii). That threshold is now well-developed in practice and merits sustained attention from any litigator with Pennsylvania exposure.

This piece addresses how the 60% threshold actually operates in litigation, how it shapes defense strategy in multi-party cases, and the open questions that remain a decade into the Act's life. The analysis draws on the firm's Pennsylvania defense practice and the developing case law from the Pennsylvania state appellate courts and the Third Circuit.

The Fair Share Act in Practice

Pennsylvania's pre-Fair Share Act framework operated under traditional joint and several liability for negligence-based claims. Any defendant found to share liability with others could be required to pay the full damages award and pursue contribution from co-defendants separately. The 2011 amendments restructured this framework around a percentage-based threshold. Under § 7102(a.1)(3)(iii), defendants found less than 60% at fault are responsible only for their proportionate share of damages. Defendants found 60% or more at fault remain jointly and severally liable for the full damages amount.

The threshold creates a binary inflection point in the apportionment analysis. A defendant at 59% fault pays 59% of damages. A defendant at 60% fault may pay the full 100%. This structural difference makes plaintiff-side strategy in multi-party cases turn substantially on whether any single defendant can be pushed across the 60% threshold, and makes defense-side strategy turn on keeping all defendants below it.

What the 60% Threshold Actually Does

The threshold does three things to multi-party litigation in Pennsylvania, each of which shapes the litigation differently than would the alternative regime of pure several liability or pure joint and several liability.

• Creates strategic asymmetry. Plaintiffs have a recovery-maximizing reason to concentrate fault on a single deep-pocket defendant. Defendants have a corresponding reason to disperse fault across the multi-party structure. This asymmetry shapes opening statements, expert testimony, and closing argument.
• Increases the value of non-party fault allocation. Pennsylvania allows fault allocation to non-parties under § 7102(a.2). For defendants near the threshold, identifying non-party contributors who absorb meaningful fault percentages can be the difference between several-only liability and full joint and several exposure.
• Reshapes settlement dynamics. Defendants near the threshold face an inflection point that creates settlement leverage running in opposite directions for plaintiffs and defendants. A defendant who believes the evidence will land them just under 60% has very different settlement incentives than a defendant who fears landing just over.

How Defense Strategy Changes

Pennsylvania defense practice under the Fair Share Act centers on three operational priorities: managing the fault allocation record, developing non-party fault as a structural defense, and calibrating settlement strategy to the threshold.

Apportionment Among Defendants

The fault allocation record is built through every phase of the litigation. Discovery scope, expert designation, and cross-examination strategy all influence how the jury will ultimately distribute fault among the defendants. Counsel for a defendant who anticipates landing near the threshold needs the discovery and trial record to develop fault allocations for co-defendants that, in aggregate with non-party allocations, leave the client below 60%.

The Pennsylvania verdict form is the focal artifact for this record-building. A defendant whose evidence supports a 50% allocation but whose verdict form allows the jury to round to 60% has not adequately protected the record. Proposed verdict forms, jury instructions on apportionment, and the wording of fault allocation questions all merit dedicated motion practice.

Non-Party Allocation

§ 7102(a.2) permits the jury to allocate fault to persons who are not parties to the action. For Pennsylvania defendants, non-party fault is not a peripheral consideration. It is often the structural difference between several-only liability and joint and several exposure. Identifying non-party contributors, developing the evidence for their allocated share, and persuading the jury to allocate to them is a primary defense priority in multi-party cases.

The procedural mechanism for non-party fault in Pennsylvania requires advance notice. Defendants who wish to argue non-party fault must comply with the procedural requirements that allow the issue to reach the jury. Failure to comply forecloses the argument and can shift exposure that should have allocated outside the party defendants back onto the client.

Practical Implications for Multi-Defendant Cases

The combined effect of the 60% threshold and non-party allocation framework produces a defense practice in Pennsylvania that operates differently than in most other states. Defense counsel handling Pennsylvania matters need to think about fault distribution from the first complaint forward, with attention to all of the following considerations.

Open Questions and Pending Authority

A decade into the Fair Share Act, several questions remain less than fully resolved. The interaction between the 60% threshold and intentional tort, strict liability, and product liability frameworks continues to develop in the appellate courts. The treatment of fault allocation in cases involving environmental claims with hazardous wastes (subject to the statutory exception under § 7102(a.1)(3)(iv)) remains an area where practitioners should expect continued case law refinement.

For now, the working framework is clear: defense counsel handling Pennsylvania multi-party litigation must treat the 60% threshold as a structural feature of the case, not as a technicality. The Act has reshaped Pennsylvania defense practice in ways that reward early strategic thinking and disciplined fault allocation record-building from the beginning of the matter forward.
