ABSTRACTLegal reasoning is commonly thought of as being based on either rules or analogies. More specifically, there is ongoing debate regarding whether precedential reasoning is best characterized as rule-based or analogical. This article continues that work by comparing recent and representative approaches from each camp, namely, Stevens's analogical model and the “rule-based” model of Horty and Rigoni. In the course of the comparison improvements on each approach are suggested and the improved models serve as the basis for the ultimate evaluation. (...) The evaluation demonstrates that the “best” approach depends on the goals one has in theorizing legal reasoning as well as the jurisprudential assumptions one is willing to make. (shrink)

Arguers sometimes cite a decision made in an earlier situation as a reason for making the equivalent decision in a later situation. I argue that there are two kinds of “case-to-case arguments”. First, there are arguments by precedent, which cite the mere existence of the past decision as a reason to decide in the same way again now, independent of the past decision’s merits. Second, there are case-to-case arguments from parralel reasoning which presuppose that the past decision was justified and (...) are used to show that an equivalent present decision would also be justified. Both arguments are a type of argument by analogy. They differ in their structures and conditions of cogency, even though they often look the same in presentation. Their similar appearance poses a risk of miss-evaluation and fallacious use. Therefore a clearly theorized distinction is important. (shrink)

This article discusses the desirability and feasibility of modeling precedents with multiple interpretations within factor-based models of precedential constraint. The main idea is that allowing multiple reasonable interpretations of cases and modeling precedential constraint as a function of what all reasonable interpretations compel may be advantageous. The article explains the potential benefits of extending the models in this way with a focus on incorporating a theory of vertical precedent in U.S. federal appellate courts. It also considers the costs of extending (...) the models in this way, such as the significant increase in the functional size of the case base and the need to provide some kind of ordering on interpretations to select a “best” interpretation. Finally, the article suggests partially incorporating multiple interpretations of dimensions as a realistic starting point for incorporating interpretations generally, and shows how doing so can help address difficulties with dimensions. The conclusion remarks on the use of interpretations to deal with inconsistent precedents. (shrink)

Key elements of John Searle’s articulation of the Standard Model of Social Ontology can be found within Max Weber’s ideal type of legal-rational authority. However, the fact that, for Weber, legal-rational authority is just one of three types of legitimate authority, along with traditional and charismatic authority, suggests limitations to the Standard Model’s scope of applicability. Where Searle takes himself to have provided an account of “the structure of human civilization,” Weber’s taxonomy suggests that Searle has only given us an (...) account of a way of being a civilization. This understanding of traditional authority also reveals why the Standard Model misconstrues the structure of ordinary, informal statuses, such as friendship. (shrink)

Some authors argue that the rule-of-law ideal gives judges a prima facie duty to provide a determinate formulation of the precedent’s general norm in all their precedent-opinions. I question that claim. I agree that judges have a duty to decide their cases based on reasons and that they should formulate these reasons in their opinions. I also agree that formulations of general norms should be the goal of common-law development and that judges have a duty to contribute to the realization (...) of this goal. However, I argue that judges may sometimes do so better if they do not provide a determinate formulation of a general norm in their opinion. Often, judges may not feel confident that they are able to formulate a good general norm for their precedent decision, even if they believe that their decision is both correct and justifiable through argument. In this case, various reasons speak against providing a determinate formulation of a general norm, including rule-of-law reasons. (shrink)

Many contemporary ethicists use case-based reasoning to reach consistent beliefs about ethical matters. The idea is that particular cases elicit moral intuitions, which provide defeasible reasons to believe in their content. However, most proponents of case-based moral reasoning are not very explicit about how they resolve inconsistencies and how they abstract principles from judgments about particular cases. The aim of this article is to outline a methodology—called Consistency Reasoning Casuistry—for case-based reasoning in ethics. This methodology draws on Richmond Campbell and (...) Victor Kumar’s naturalistic model for the resolution of inconsistencies between the content of intuitions about particular cases. I argue that reasons similar to those that motivate their model also support a more abstract form of moral reasoning that goes beyond mere resolutions of inconsistencies between case judgments and demands the formulation of more abstract moral norms. Consistency Reasoning Casuistry, it is argued, is a good candidate for a methodology for case-based moral reasoning that is in harmony with paradigms of contemporary moral psychology and that can accommodate the methodology implicit in the work of many contemporary ethicists.

Coherentists fail to distinguish between the individual revision of a conviction and the intersubjective revision of a rule. This paper fills this gap. A conviction is a norm that, according to an individual, ought to be ascribed to a provision. By contrast, a rule is a judicially ascribed norm that controls a case and is protected by the formal principles of competence, certainty, and equality. A revision of a rule is the invalidation or modification such a judicially ascribed norm, provided (...) that the judge meets the burden of argumentation of formal principles. Thus, judges can revise their convictions without changing the law. (shrink)

The passage of time influences the content of the law and therefore also the validity of legal arguments. This is true even for charter-arguments, despite the widely held view that constitutional law is made to last. In this paper, I investigate the reason why the sanctity-of life argument against physician assisted suicide lost its validity between the Supreme Court decision in Rodriguez v. British Columbia in 1993 and Carter v. Canada in 2015. I suggest that a rhetorical approach to argument (...) evaluation is the best basis for a satisfying explanation. (shrink)

En marzo de 2021 se reformó la Constitución mexicana para transitar a un sistema de precedentes. Esta enmienda establece que las “razones” de las sentencias de la Suprema Corte serán obligatorias para los tribunales inferiores. Sin embargo, la reforma se enmarca en una arraigada práctica de tesis jurisprudenciales, i. e., enunciados abstractos identificados por la misma Corte al resolver un caso. Además, no hay consenso sobre qué son estas razones y por qué deberían ser vinculantes. El objetivo de este artículo (...) es identificar las posibles concepciones de razones para revelar los distintos roles de la Corte en la creación del derecho judicial. Se utilizan nociones de la ratio decidendi del common law como herramientas de introspección para identificar cuatro modelos de creación del derecho en la práctica mexicana, a saber: legislación judicial, reglas implícitas, justificaciones político-morales, y categorías sociales. Aunque la primera concepción parece ser la dominante, las alternativas amplían el abanico para entender cómo es que la Corte crea derecho dependiendo del contexto interpretativo en que opere.

In March 2021, the Mexican Constitution was amended to transition to a system of precedents. This amendment mandates that the “reasons” of Supreme Court rulings will be binding on the lower courts. However, the reform is rooted in a long-standing practice of ‘Tesis’, i.e., abstract statements that the Court itself identifies when deciding a case. Moreover, there is no consensus as to what these reasons are and why they should be binding. The aim of this article is to identify the (...) possible conceptions of reasons to explore the Court’s different judge-made law roles. Different common law conceptions of the ratio decidendi are used as “mirrors” to identify four models of judicial lawmaking in Mexican practice, namely: judicial legislation, implicit rules, moral-political justifications and social categories. Although the first model seems to prevail, the others provide means for a broader understanding of how the Court creates law depending on the interpretative context in which it operates. (shrink)
