Overdetermined Causation Cases, Contribution And The Shapley Value, Samuel Ferey, Pierre Dehez

Chicago-Kent Law Review

The overdetermined causation cases (duplicative causation, concurrent causes, etc.) challenge the consistency and relevance of the but for test in torts. A strict application of the but for criterion to these cases leads to paradoxes and solutions that violate common sense. This explains why a large amount of literature has been developed in philosophy and jurisprudence to provide more accurate causation criteria. This paper adds to this literature by considering over-determination cases from an economic and mathematical point of view. Following Martin van Hees and Matthew Braham in their 2009 article Degrees of Causation, we consider over-determined cases through cooperative …

Causation And Standard Of Proof From An Economic Perspective, Bruno Deffains, Claude Fluet, Maiva Ropaul

Chicago-Kent Law Review

Causation is a problematic notion, as explained by Ronald Coase regarding the “bilateral nature” of externalities. However, causation has played only a minor role in standard economic models of civil liability. An exception is the sub-literature on Uncertainty Over Causation and the Determination of Civil Liability, the benchmark paper written by Steven Shavell in 1985: “. . . the familiar notion that for parties to be led to reduce accident risks appropriately, they should generally face probability-discounted or ‘expected’ liability equal to the increase in expected losses that they create. This, of course, is naturally the case in the absence …

Causation, Counterfactuals And Probabilities In Philosophy And Legal Thinking, Florence G'Sell

Chicago-Kent Law Review

Since the function of causation is to recount and explain observed phenomena in order to make a judgment on civil liability, promoting a purely legal conception of causation appears to be problematic. The purpose of this contribution is to show that the various theories of causation found in legal thinking are, in many respects, the extension of philosophical developments. Therefore, two points will be made. The first part of this paper will present the three main theories that are discussed by contemporary philosophers. The second part will show how philosophical accounts are present in legal thinking. This part will deal …

Causation In Hepatitis B. Vaccination Litigation In France: Breaking Through Scientific Uncertainty?, Jean-Sebastien Borghetti

Chicago-Kent Law Review

Vaccination against hepatitis B has been available since 1982 and is strongly recommended by most health professionals. In France, the hepatitis B vaccine is very widespread, but it has come under suspicion that it can cause demyelinating diseases such as multiple sclerosis. Several epidemiological studies have been carried out to discover if there is indeed a connection between the hepatitis B vaccination and demyelinating diseases, but no such connection has been established so far. Many cases have nevertheless been brought before French courts, in which plaintiffs argue that they have developed a demyelinating disease due to the hepatitis B vaccination, …

Material Contribution To Risk In The Canadian Law Of Toxic Torts, Lynda M. Collins

Chicago-Kent Law Review

Causation is acknowledged as the single biggest hurdle to recovery for plaintiffs in toxic tort actions in Canada (and elsewhere). Scientific uncertainty involving questions of both generic and specific causation has frequently precluded recovery for plaintiffs even where defendants have negligently exposed them to toxic risk. Three types of uncertainty have been identified: plaintiff indeterminacy (where we know that the defendant has harmed some proportion of a particular population but no individual can prove causation); defendant indeterminacy (where we know that a group of defendants has harmed a particular plaintiff or plaintiffs but each can escape liability by pointing the …

Causation In Cases Of Evidential Uncertainty: Juridical Techniques And Fundamental Issues, Ken Oliphant

Chicago-Kent Law Review

This paper reviews from a comparative legal perspective the range of juridical techniques that have been developed in different legal systems to address perceived problems of uncertain alternative causation. It finds that the process of development has generally proceeded in an ad hoc and unprincipled fashion, without regard for overall coherence. It argues for a more principled legal approach in which the appropriate legal response (full liability, proportional liability or no liability) is adopted on the basis of a ranking of the different categories of cases in which problems of causal uncertainty can arise, reflecting the strength (or weakness) of …

Attribution Of Liability: An Economic Analysis Of Various Cases, Michael Faure

Chicago-Kent Law Review

In many cases liability is attributed in a different way than through the clear cut situation where one tortfeasor causes harm to one single victim. Those cases of complicated attributions in tort law are analyzed in this article from an economic perspective. After briefly sketching the economic starting points in section II, the way in which multiple tortfeasors are dealt with in the law is analyzed in section III. Section IV analyzes the perspective of multiple tortfeasors in law and economics, distinguishing between the situations of full solvency, insolvency and insurability of more particularly joint and several liability. The article …

Economic Analysis Of Liability Apportionment Among Multiple Tortfeasors: A Survey, And Perspectives In Large-Scale Risks Management, Julien Jacob, Bruno Lovat

Chicago-Kent Law Review

The economic analysis of civil liability aims to demonstrate how the civil liability system can be set to provide the potential injurers with optimal incentives to regulate the level of risk they bear. However, despite a wide range of applications, there are few studies on the apportionment of liability between several tortfeasors. In this article, we especially focus on the case of an industrial activity involving a firm, whose activity is potentially harmful for the society, and one of its input providers. They both have an impact on the level of risk through an effort in care and quality. After …

Expanding The After-Acquired Evidence Defense To Include Post-Termination Misconduct, Holly G. Eubanks

Chicago-Kent Law Review

In 1995, the United States Supreme Court formulated the after-acquired evidence defense in employment discrimination litigation. The defense, if successfully established, allows the defendant to limit the damages available to the plaintiff. In order to assert the defense, a defendant must establish that it would have terminated the plaintiff based on after-acquired evidence of wrongdoing if the defendant had known of the wrongdoing prior to the termination. The defense, as generally accepted, applies to misconduct that occurs during employment and misconduct that occurs prior to employment in the application process. This note considers the potential expansion of the defense to …

Reasonable Royalties And The Calculation Of Patent Damages: Reflections And Recommendations For A Fair And Adequate Calculating Basis Of Reasonable Royalties In Terms Of Harmonization Of China-Taiwan Regional Patent Laws, Chung-Lun Shen

Chicago-Kent Journal of Intellectual Property

Among the substantive issues of patent law, patent enforcement has received increasing focus in the global community. Owing to the intangibility of patents, and in view of the symmetry of exclusive rights with damages, courts and juries have difficulty calculating appropriate damages for patent infringement. Compared with the traditional calculation of patent damages, which rests upon the patentee’s losses or infringer’s profits, the basis of reasonable royalties provides a flexible concept for accommodating damages when the patentee cannot adequately prove damages, especially, when the patented or infringing products were not available in the market at the time of infringement. Until …

Medical Malpractice: The Italian Experience, Claudia Dimarzo

Chicago-Kent Law Review

Beginning with an investigation into the problematic nature of medical liability, the Article overviews the most significant approaches taken by courts and scholars in order to establish whether the physician's position before the patient is comparable with that of either a tortfeasor or a contractor.

Having explained that the most recent approaches in this regard tend toward the recognition of the contractual nature of medical liability, the Author discusses the implications of such a solution, making specific reference to the following issues: 1) the assignment of the burden of proof (along with the distinction between obligations of means and obligations …

Medical Malpractice And Compensation In South Africa, L. C. Coetzee, Pieter Carstens

Chicago-Kent Law Review

This article gives an overview of current medical malpractice law in South Africa. The following aspects are covered: The overall scheme for preventing and redressing medical errors and adverse events, including regulation, criminal and civil liability, and social and private insurance, and the relationships among these various systems; the details of the applicable liability and compensation systems, including criteria defining qualification for compensation, causation and "loss of chance," liability for failure to obtain informed consent, as well as matters of proof and gathering of evidence. The authors note the difficulty they had in obtaining empirical data on medical errors and …

Res Ipsa Loquitur In The Restatement (Third) Of Torts: Liability Based Upon Naked Statistics Rather Than Real Evidence, Daniel J. Pylman

Chicago-Kent Law Review

Using the doctrine of res ipsa loquitur, courts have accounted for the fact that there may be instances where a plaintiff is unable to present any evidence of a specific negligent act or omission and yet where the injury to the plaintiff and the surrounding circumstances suggest that the defendant did in fact negligently cause the injury. Despite the fact that the doctrine of res ipsa has been well-accepted by American courts, the courts have struggled to appropriately formulate the doctrine so as to achieve its important purpose of allowing recovery in appropriate situations while not formulating it so …
