Introduction: Preemption in Flux

Catherine Sharkey's essay, What Riegel Portends for FDA Preemption of State Law Product Liability Claims, represents an ingenious effort to work between the horns of the most pressing dilemma in today's law of federal preemption with her "agency reference model" of preemption.[1]  This issue is hot today because the Supreme Court recently held in Riegel v. Medtronic, Inc. that the Medical Devices Act preempted a plaintiff's state product liability claims alleging defective design of a balloon catheter after plaintiff suffered grievous injuries when the device ruptured inside his right coronary artery.[2]  It is worthy of note that here the treating physician made two controversial decisions: (1) he used the catheter on a patient whom FDA warnings classified as unfit for the treatment; and (2) he overinflated the catheter.[3]  The problem of FDA preemption also arises in the context of a drug manufacturer's duty to warn in a case scheduled to come before the Supreme Court next year, Wyeth v. Levine.[4]  In that case, the Vermont Supreme Court upheld a damage award on the ground that Wyeth should have warned the plaintiff against using its drug, Phenergan, in a risky procedure that the FDA had explicitly authorized.  More specifically, the FDA-approved warning label allowed Phenergan to be injected intravenously by a so-called "IV push," or rapid injection into a vein by syringe, so long as physicians were alert of the risk of hitting an artery instead of a vein.  The plaintiff suffered gangrene and consequent loss of a limb when the IV needle mistakenly punctured the artery.  Plaintiff argued that Wyeth's label "should not have allowed IV push"—period.[5]

To understand the legal issues raised by these two cases, it is useful to set the background with a thumbnail sketch of the modern law of preemption.  All parties agree that some principles of interpretation are needed to work out the interrelationships between federal and state action that covers the same sphere of action.  It is understood as well that the law of preemption divides itself into two halves.  The first half deals with express preemption, which holds that if the federal government makes it clear—itself a term that turns out often to be unclear—that its statute preempts the state law, then the issue is over.  Under the Supremacy Clause[6] of the United States Constitution, the lowliest federal action trumps the most grandiose state pronouncement.  Conversely, if the federal statute makes it clear that the state law may peacefully coexist with it, a system of dual enforcement is appropriate.

In many cases, of course, the question of preemption is not resolved by express preemption, at which point the common view holds that there are three possible grounds for implied preemption.  The strictest standard allows for preemption only in cases of actual conflict, such that there must be a clear inconsistency between what the federal government and the state government each allow or require.  Second, it is often stated that the preemption in question only arises in those cases where the imposition of the state liability will frustrate the ends of the federal statute.  Finally, a third form of preemption argues that preemption does not require this form of explicit conflict, but is satisfied if it appears that the federal statute has occupied the field, blocking state efforts to impose sanctions within that field even if there is no explicit conflict.  For our purposes, the first and third forms of preemption are the most relevant ones.  Drug cases are more problematic than device cases because the Medical Devices Act does contain an explicit preemption provisions for medical devices, in contrast to drug cases, which are subject to no explicit form of preemption.[7]

Professor Sharkey's distinctive contribution to this debate is her careful elaboration of the "agency reference model" of preemption, which enriches the debate over preemption by consciously incorporating administrative law principles resting on the twin pillars of Chevron U.S.A., Inc. v. Natural Resources Defense Council, Inc.[8] and Skidmore v. Swift & Co.[9] Sharkey's "agency reference model" treats Chevron and Skidmore as defining an administrative universe in which the level of deference given an administrative action increases with thoroughness and formality of the processes that generate the disputed ruling.[10]  Sharkey's proposal, elaborated with her customary vigor and clarity in her article on Riegel, explains how the key interpretive tools of the administrative state can shed light on the preemption question.

This brief Comment renews my defense of strong field preemption for FDA regulation.  In Part I, I shall set out the emergence of modern preemption law in light of the vast expansion of federal power after the New Deal with special reference to two cases of great current concern, Riegel[11] and Levine.[12]  Thereafter, in Part II, I shall comment first not on Professor Sharkey's article, but on a recent essay by David Kessler and David Vladeck that takes the strong view that the doctrine of implied preemption should not be applied in duty-to-warn drug cases.[13]  Then, in Part III, I address Professor Sharkey's agency model, and lastly, in Part IV, I offer a brief capitulation of my field preemption position.

I.  Preemption After the New Deal

Historically, the consolidation of the New Deal administrative state meant the federal government faced few, if any, limitations on the scope of its power given the expansive reading of the Commerce Clause.[14]  This rapid expansion of federal power took place in an environment highly sympathetic to regulation at both the national and the state levels.  State powers of regulation have never been constrained by the federal constitutional doctrine of enumerated powers.  But post-1937, the broad construction of the Commerce Clause gave the federal government total power to regulate in areas formerly reserved to the states, except in the most marginal of cases.[15]

Riegel and Levine offer an effective window around which to organize a discussion of preemption in the modern regulatory debate.  What should be done to ease the tension that arises when state and federal governments regulate concurrently, arguably in inconsistent ways?  We should not work ourselves into a deep philosophical funk that regards the federal government as congenitally unable to speak with a clear voice. Of course it can be done.[16]  However, as Sharkey rightly points out, passing federal regulation is not merely a grammatical exercise.  It is also a highly political one, where sides jockey for position on the key question of whether state actions will be allowed in an area once the federal government has entered the field.  This tension is real enough when both the federal and state government act through regulation.  The federal statutes clearly preempt state "requirements" resulting from direct legislative or administrative action. The question of whether common law actions that can compel action are preempted is much closer, and there has been some division of opinion.[17]  But the stakes are a thousand-fold higher when the question turns to whether the federal statute will trump state law tort causes of action that have expanded vastly since the adoption of the Second Restatement of Torts, which was published in 1966.  All too often Congress combines a provision that first preempts state law but then expressly preserves common law rights of action.[18]  What's a judge to do when Congress tries to square the circle?

Generally speaking, three schools of thought have arisen to deal with this question.  The first of these rests on what is commonly termed the "presumption against preemption," which means that all doubtful statutes should be construed in ways that do not block the imposition of additional sanctions at the state level.  Justice Douglas's famous passage in Rice v. Santa Fe Elevator Corp. put it as follows:

Congress legislated here [on the matter of warehouse receipts] in a field which the States have traditionally occupied.  So we start with the assumption that the historic police powers of the States were not to be superseded by the Federal Act unless that was the clear and manifest purpose of Congress.  Such a purpose may be evidenced in several ways.  The scheme of federal regulation may be so pervasive as to make reasonable the inference that Congress left no room for the States to supplement it.  Or the Act of Congress may touch a field in which the federal interest is so dominant that the federal system will be assumed to preclude enforcement of state laws on the same subject.  Likewise, the object sought to be obtained by the federal law and the character of obligations imposed by it may reveal the same purpose.  Or the state policy may produce a result inconsistent with the objective of the federal statute.  It is often a perplexing question whether Congress has precluded state action or by the choice of selective regulatory measures has left the police power of the States undisturbed except as the state and federal regulations collide.[19]

This passage has a Job-like quality, for what the Court giveth in the first sentence—the need to show a clear and manifest purpose—it taketh away in the three enumerated exceptions.  Hence the tripartite debate.  Ernest Young argues that the Rice presumption should be broadly read to preserve the historic role of the states in local regulation.[20]  This view favors no implied preemption.

At the opposite extreme, according to the second school of thought, the arrival of federal regulation is held to transform the regulatory universe.  This view, which I have defended with Michael Greve, insists that concurrent regulation mistakenly ratchets up government control so that the most intrusive regulator always wins.  It therefore adopts the view of field preemption: let the regulation cover the topic, and the state intervention is banned.[21]  The third position, which Sharkey champions, falls in the middle.  It avoids the strong presumption against concurrent regulation and insists that there be some demonstration of an actual conflict before the state rules are shown. Let us turn now to the various positions.

II.  The Kessler-Vladeck Position

In their article entitled A Critical Examination of the FDA's Efforts to Preempt Failure-to-Warn Claims, Kessler and Vladeck begin their analysis of drug preemption cases by addressing institutional issues.  They claim that the FDA performs admirably but is constrained by limited resources, which leads to mistakes of wrongfully letting dangerous drugs onto the market.  Accordingly, they see the private state tort action as an important backstop to administrative failure by creating a second chance to correct the mistakes in the original FDA process.[22]  They further argue that this ex post review has significant advantages because it can rely on information about drug safety, side effects, and effectiveness that accumulates only after a drug is extensively used on the market.  As a textual matter, Kessler and Vladeck note that the Food and Drug Administration Amendments Act of 2007 (FDAAA)[23] offers no safe harbor for pharmaceutical companies because it reaffirms their ability under the FDA's warning system to update their warnings based on newly acquired information.[24]  Finally, they pooh-pooh the FDA's recent Preemption Preamble which announces its new-found conclusion that its warning labels preempt any state law judgment to the contrary.[25]

Initially, much of their proposal builds on the presumption against preemption, which gains strength from the obvious contrast between the Medical Device Act, which created preemption in Riegel,[26] and the want of any preemption provision dealing with drugs, as in the Levine case. But even this point is not as clear as they claim. Levine presents a situation where the FDA gave explicit approval to the exact treatment, notwithstanding the precise side effect mentioned in the original warning.[27]  What would count as new information to render that explicit authorization obsolete?  The mere occurrence of the identified side effect can't do it because it was warned of in advance.  And in Levine the sketchy record reveals no evidence collected after the drug hit the market indicating a higher incidence of this failure (and perhaps others) that might call for a reevaluation of the risk/reward ratio for that procedure.  But making that determination is hard because new information comes in dribs and drabs, ruling out some defining moment at which the new warning is mandated.  Extensive litigation could easily produce a breakdown of uniformity, which the FDA has rightly decried.  The FDAAA does not solve that issue.

In addition, the structural flaws in the Kessler-Vladeck approach are still more profound because of the simplistic way that they integrate the litigation process with the FDA approval process.  Kessler and Vladeck consider only one kind of error in the drug approval process: its willingness to allow dangerous drugs, like Vioxx, on the market.  But two kinds of errors are evident: letting drugs on the market that should be kept off and taking drugs off of the market that should be left on. The FDA is buffeted with strong criticisms as many scholars and industry observers deplore its risk-averse attitude.[28]  I recently helped organize a conference on the FDA role in oncology cases with the American Enterprise Institute, where oncology experts reinforced this point by claiming that the FDA did not have the expertise to do state of the art review.[29]  Kessler and Vladeck are wrong to suppose that the undermanned and intellectually outgunned FDA will simply roll over by allowing new treatments onto the market. Quite often these insecurities translate into a systematic reluctance to let many drugs on the market, lest the agency has to pay a political price if something goes wrong.  That cautious form of institutional protectionism translates into ever longer clinical trials and administrative delays.  All in all, the real risk is that too few drugs will reach the market, not too many.

After recognizing these two forms of error in regulation, the role of litigation in the FDA approval process is even more problematic.  Where the FDA incorrectly blocks a drug from entering the market, litigation can do nothing to correct that error. Where the regulatory process lets drugs correctly on the market, litigation remains costly even if it vindicates the defendant.  Worse still, litigation has disastrous consequences if safe and useful drugs are subject to extensive tort liability. Yet Kessler and Vladeck consider only the scenario where the permit is incorrectly granted, and litigation rightly imposes liability, presumably at the right financial levels.  Why ignore those possibilities, where judicial intervention through the tort system may only compound the errors of an overly harsh regulatory regime?  In evaluating the role of the tort system, it is wrong to consider only those instances where it may do some good, albeit at a high cost, while ignoring the frequent instances where its use is either costly or harmful.  The complete analysis must cover all possibilities.

At this point, we must ask whether the error rates in litigation will be low enough to make their system work.  Probably not, for a number of reasons.  First, litigation comes too little, too late. The drugs that usually generate the most litigation—such as Rezulin and Vioxx—usually are withdrawn before litigation commences.  Indeed the plaintiffs' bar rightly free rides on FDA determinations, reducing the social gain from litigation.

Second, Kessler and Vladeck do not defend the soundness of the current tort system whose problems are legion.  Litigation does not simply ask if FDA warnings are adequate. It must also decide knotty questions of causation: did this drug, or the excess amounts of the drug, cause the plaintiff's malady?  Would the needed information have changed the plaintiff's decision to use the drug? These questions are hard to disentangle for plaintiffs suffering from multiple ailments treated by multiple drug regimens.  Often, no one knows for sure if a particular drug has been taken at all, taken in the right amounts, at the right time, or in the prescribed fashion.  Likewise, liability determinations cannot isolate the effect of a given warning in any individual case.  In contrast, the preemption rule forces the ex ante determination of the relevant issues, free from the distractions of any complex tort litigation.

The fact patterns of Riegel and Levine illustrate some of the complications in using the litigation process.  In Riegel, the treating physician inflated the balloon to ten atmospheres of pressure when it was only rated at eight atmospheres.  He also used the balloon in a patient who was not rated as a suitable candidate.[30]  Does his decision to ignore the label restrictions qualify as medical malpractice? Not if the decision was made by conscious choice instead of simple neglect. If other treatments have little chance of success, the doctor may rightly decide to take a long-shot by ignoring the warnings, and the jury may decline to impose malpractice liability.[31]  So forget about preemption for the moment—does it make sense to hold the manufacturer liable for the physician's choice because the outcome may have been unforeseen, or even foreseen but consciously disregarded?  We are not dealing here with teenagers who speed on tires rated for 80 miles per hour.  We are dealing with devices that go through professional channels such that the upstream player should never be held accountable for the mistakes of the downstream players.  If a state law finds liability, should Medtronic now rate its balloon for use only at six atmospheres—and run the risk that the people in the seven and eight atmospheres category will go without treatment?  No way.

Similarly, in Levine, we know that the risk of arterial puncture is ever present.  But who has better knowledge of the magnitude of the risk in a particular patient, the company that supplies Phenergan or the physician who can look at the condition of the patient's veins and arteries?  These variations matter because they show that the physician is in the best position to determine if a treatment that is undesirable in some patients is desirable in others.  It is in fact dangerous for the company to recommend that all physicians avoid the IV push if the other treatment options turn out to be more dangerous.  The field preemption rule thus protects patients from the systematic errors of the tort system.  On policy grounds, nothing commends the Kessler-Vladeck proposal.

III.  Sharkey's Agency Model

Sharkey's agency proposal is superior to the Kessler-Vladeck position because of its greater willingness to accept conflict preemption.  Therefore, her proposal would allow Wyeth to keep its case from the jury if the particular point in dispute was subjected to intensive agency review. In her words, "courts need a fine-grained account of the precise regulatory review conducted by the agency and evidence as to its compatibility with state law tort claims."[32]  Moreover, that inquiry cannot be made on a blank record, but is intended "to facilitate input from federal agencies on these issues."[33]  In doing so, "it is critical to discern whether the FDA has weighed in on the precise risk the state tort action likewise seeks to regulate."[34]  In the end, her position leads to Skidmore deference, which asks whether the agency determination has the "power to persuade."[35]  This deference in turn depends on "the thoroughness evident in its consideration, the validity of its reasoning, [and] its consistency with earlier and later pronouncements."[36]

Sharkey's proposal thus allows the FDA to insert itself between a drug manufacturer and tort liability.  But its flexibility comes at too high a price. The successful application of the Skidmore standard depends in large measure on the number of occasions in which its far-reaching inquiry is needed.  Skidmore involved a one-and-done dispute over whether all workers who were required to be on-call at night were entitled to overtime pay under the Fair Labor Standards Act.[37]  The case needed a single fact determination, without obvious repetition. The administrative agency only made one key decision about basic policy, which was done without any knowledge of, or concern with, the facts and circumstances of any particular case. Skidmore decided only that the Administrator's rulings had to be taken into evidence in the case, where it was entitled to some respect.[38]

Those burdens are trivial compared to wading through the normal complex FDA record.  In addition, this onerous task would have to be done in thousands of separate cases.  The sheer weight of litigation would open up the possibility of third-party depositions of present and past FDA employees, and extensive discovery of FDA doctrines. Skidmore is not scalable, and its huge protracted battles over preemption may only be a prelude for the underlying litigation.  The simplest approach in these cases is to follow the kinds of information that was introduced in Skidmore, namely a broad statement of policy.  In this context, this approach would exclude all the particular FDA judgments in reviewing the drug, but not the Preemption Preamble, which would be admissible to give some indication of the FDA's policy.  Without this sort of restriction, the Sharkey inquiry in Levine could collapse into the approach of Kessler and Vladeck, barring preemption across the board.

The Sharkey proposal would also undermine long-term administrative stability.  As she duly notes, my earlier piece on preemption describes the dangers of agency flip-flop, often in response to intense lobbying pressures from all sides.[39]  For example, if the Preemption Preamble tipped the balance in favor of preemption under Skidmore, that precarious result could be gone with the next change of the guard in the White House or the FDA. Given the billions of dollars at stake, that flip-flop will not be a simple random event. It will be a target of opportunity that will embolden lobbyists of all stripes.  Those changes flout any notion of a rule of law as a set of stable social expectations.[40]

Finally, Sharkey's proposal does not correct the deficient error-cost analysis in the Kessler-Vladeck plan.  Nor does it take into account the substantive weaknesses of the current duty to warn law in most states, with the high risks of false positives on liability.  The proposal's ex ante effects are also likely to deter new drug innovation by adding private law sanctions to the impressive administrative obstacles that now impede new drug development.  Finally, its helter-skelter results undermine the uniformity that grounds the public acceptance of the law.

IV.  Field Preemption

By process of elimination, only field preemption remains standing.  I shall not rehearse the case for this position again here.[41]  However, I do wish to add one point that I have since developed elsewhere. It is a mistake to think that the only ways to secure public health are through some combination of sanctions through the FDA permit system and the tort system.  Right now an impressive role in monitoring product safety is played by intermediate organizations such as the National Comprehensive Cancer Network, which supervises the clinical use of off-label drugs, i.e. those which are taken for one indication, although they actually received FDA approval for another.[42]  This voluntary system is quick on the uptake and gets information on adverse events out to the profession faster than the dilatory FDA processes and the interminable tort litigation.  So, it seems unwise to handle the issue of drug information by coercion when persuasion is still available.  It is one way in which we can get more for less.

16.  Easy cases are in practice hard to find, in part because the only cases that make it to the Supreme Court have some genuine difficulty. One candidate for the easy class is United States v.

The bottom line is that the Levine Court upheld common-law actions for negligence and failure-to-warn in the face of not one, but two, specific determinations by the FDA regarding the precise regulated risk. The FDA-approved label warned of the risk of harm that transpired in the case . . . [and,] [a]fter initial approval, the manufacturer proposed a different warning to the FDA . . . and was told to "[r]etain verbiage in current label."
