The Common Law Prohibition on Party Testimony and the Development of Tort Liability

For two and a half centuries of accident law’s history, between about 1600 and 1850, neither the plaintiff nor the defendant in a tort suit could testify in that suit. In fact, during this period the parties could not testify in any civil suit, and the defendant could not testify in a criminal case. These prohibitions were features of a broader common law rule providing that any potential witness who had an “interest” in the outcome of a case was not competent to testify in it. It was not until statutes abolishing this evidentiary prohibition were enacted in England in the 1840s, and in the United States between the late 1840s and the 1890s, that the parties were permitted to testify in tort (and other) suits. This Essay addresses the influence of the prohibition against party testimony on the development of tort liability prior to the middle of the 19th century.

Contract Theory On and Off the Grid

In The Role of Formal Contract Law and Enforcement in Economic Development, Michael Trebilcock and Jing Leng examine the importance of a formal institution of contract law to economic growth. Trebilcock and Leng find the evidence in support of the hypothesis that a formal contract institution promotes economic growth inconclusive, but they do not reject the hypothesis. Although the role of formal contract law in economic growth can be considered as a purely academic matter, the significance of the topic comes from its connection to the question whether developing countries should adopt or strengthen formal contract institutions to enhance growth.

Even if formal contract law does play an important role in development, however, that might not be sufficient to justify state enforcement of private agreements. The legitimacy of an institution of contract belongs to the domain of contract theory. This Essay considers whether contemporary theories of contract are relevant to legal systems without an established tradition of Western legal institutions. The Essay reviews contract theories of Peter Benson, Melvin Eisenberg, Charles Fried, James Gordley, Thomas Scanlon and Michael Trebilcock. The Essay concludes that even if a formal institution of contract does have the potential to promote growth, these contemporary theories tell us very little about the proper content, desirability, or legitimacy of contract law in societies other than those in which Western private law institutions are already well established.

The Role of Formal Contract Law and Enforcement in Economic Development

The primary inquiry of this Essay is consequentialist: whether the existence of a formal contract law and enforcement regime significantly contributes to economic growth in developing countries. As the Essay elaborates, two different hypotheses emerge from the literature. One takes the view that strong formal contract law and enforcement mechanisms are indispensable to economic development, while the other contends that much economic development is realizable through informal contracting mechanisms. To test the validity of these two hypotheses, we provide a critical review of existing literature, including an investigation of two cases of great contemporary development significance: the so-called “China Enigma” and the “East Asian Miracle.” In both of these cases, high rates of economic growth have been achieved, often in the absence of strong formal contract law and enforcement regimes.

We argue that at low levels of economic development informal contract enforcement mechanisms may be reasonably good substitutes for formal contract enforcement mechanisms, but become increasingly imperfect substitutes at higher levels of economic development involving large, long-lived, highly asset-specific investments or increasingly complex traded goods and services, especially outside repeated exchange relationships. Thus, the mix of mechanisms that are likely to ensure both a fair and efficient domain of contracting in developing countries is a function of highly context-specific factors that defy easy generalizations. We conclude that on one of the central questions in contemporary development debates – do good institutions cause growth, or does growth cause good institutions? – the answer, in the context of contract enforcement mechanisms, is a nuanced one.
