Overview

Federal preemption is the doctrine by which federal law displaces or supersedes state law, including state tort claims. In personal injury practice, preemption is a defense that can eliminate entire categories of claims. Understanding when preemption applies and when it does not is critical for plaintiff attorneys evaluating cases involving regulated products, federal employees, transportation, and employee benefits.

This guide covers preemption doctrines and their application across the major PI practice areas: automotive safety, pharmaceuticals, medical devices, railroad, aviation, maritime, ERISA, and telecommunications.

Key takeaway
Federal preemption is a defense, not a blanket bar. The presumption against preemption means state tort claims survive unless Congress clearly intended to displace them. For every regulated product, analyze the specific statutory scheme, identify savings clauses, and frame claims to fall outside the preempted zone.

Types of Preemption

Express preemption occurs when Congress explicitly states that federal law supersedes state law. Implied field preemption occurs when federal regulation is so pervasive it leaves no room for state supplementation. Implied conflict preemption occurs when state law conflicts with federal law through impossibility or by creating an obstacle to federal objectives.

Pharmaceutical Preemption

Brand-name drug failure-to-warn claims are generally not preempted under Wyeth v. Levine (2009). Generic drug claims are broadly preempted under PLIVA v. Mensing (2011) and Mutual Pharmaceutical v. Bartlett (2013) because generic manufacturers cannot independently change their labels. Manufacturing defect claims against generics may survive.

Medical Device Preemption

Class III devices with full premarket approval (PMA) have broad preemption under Riegel v. Medtronic (2008). Devices cleared through the 510(k) process are generally not preempted under Medtronic v. Lohr (1996). Even for PMA devices, parallel claims alleging the manufacturer violated FDA's own requirements may survive.

Automotive & Transportation

The National Traffic and Motor Vehicle Safety Act has both a preemption clause and a savings clause. Under Geier v. American Honda (2000), the savings clause does not override conflict preemption. Claims based on features not addressed by FMVSS are not preempted.

ERISA Preemption

ERISA contains one of the broadest preemption clauses in federal law, preempting any state law that relates to an employee benefit plan. This affects PI practice through insurance coverage disputes, subrogation liens, and disability benefit claims. When ERISA applies, remedies are drastically limited.

Common Questions

What is federal preemption in a personal injury case?

Federal preemption means a federal law overrides a state law, including state injury claims. When a product is regulated by a federal agency, the manufacturer may argue that your California injury claim is displaced by federal law. Whether the defense succeeds depends on the specific federal statute, whether it has a savings clause preserving state claims, and whether your specific claim conflicts with the federal scheme.

Are injury claims against generic drug companies preempted?

Most failure-to-warn and design defect claims against generic drug manufacturers are preempted under the Supreme Court decisions in PLIVA v. Mensing and Mutual Pharmaceutical v. Bartlett. Generic manufacturers cannot independently change their labels, so state claims requiring different warnings are impossible to comply with alongside federal law. Manufacturing defect claims may survive.

Can I sue for injuries caused by an FDA-approved medical device?

It depends on how the device was approved. Devices that went through the rigorous premarket approval process have broad preemption under Riegel v. Medtronic. But devices cleared through the 510(k) process are generally not preempted. Even for PMA devices, claims that the manufacturer violated FDA's own requirements may survive as parallel claims.

Does ERISA preemption affect my injury case?

ERISA preemption affects your injury case primarily through health insurance liens and coverage disputes. If your employer-sponsored health plan denies treatment, ERISA preempts state bad faith claims and limits remedies to the plan benefits themselves. ERISA also governs subrogation and lien rights, potentially overriding California's made-whole doctrine.
