Argumentation as the public exchange of reasons is widely thought to enhance deliberative interactions that generate and justify reasonable public policies. Adopting an argumentation-theoretic perspective, we survey the norms that should govern public argumentation and address some of the complexities that scholarly treatments have identified. Our focus is on norms associated with the ideals of correctness and participation as sources of a politically legitimate deliberative outcome. In principle, both ideals are mutually coherent. If the information needed for a correct deliberative (...) outcome is distributed among agents, then maximising participation increases information diversity. But both ideals can also be in tension. If participants lack competence or are prone to biases, a correct deliberative outcome requires limiting participation. The central question for public argumentation, therefore, is how to strike a balance between both ideals. Rather than advocating a preferred normative framework, our main purpose is to illustrate the complexity of this theme. (shrink)

The aim of the article is to develop precise epistemic rules for good public political arguments, by which political measures in the broad sense are justified. By means of a theory of deliberative democracy, it is substantiated that the justification of a political measure consists in showing argumentatively that this measure most promotes the common good or is morally optimal. It is then discussed which argumentation-theoretical approaches are suitable for providing epistemically sound rules for arguments for such theses and for (...) the associated premises, rules whose compliance implies the truth or acceptability of the thesis. Finally, on the basis of the most suitable approach, namely the epistemological one, such systems of rules for the required types of arguments are presented that fulfil the conditions mentioned.

This paper analyzes legal fact-argumentation in the framework of the argumentation-based litigation game by Xiong :16–19, 2012). Rather than as an ontological one, an ALG treats a legal fact as a fact-qua-claim whose acceptability depends on the reasons supporting it. In constructing their facts-qua-claims, parties to an ALG must interact to maintain a game-theoretic equilibrium. We compare the general interactional constraints that the civil and common law systems assign, and detail what the civil, administrative, and criminal codes of mainland China (...) require of the suitor, the respondent, and the trier to establish their respective S-, R- and T-facts. We also offer an improved version of the legal syllogism. (shrink)

Addressing the slippery slope argument (SSA) in legal contexts from the perspective of pragma-dialectics, this paper elaborates the conditions under which an SSA-scheme instance is used reasonably (rather than fallaciously). We review SSA-instances in past legal decisions and analyze the basic legal SSA-scheme. By illustrating the institutional preconditions influencing the reasoning by which an SSA moves forward, we identify three sub-schemes (causal SSA, analogical SSA, and Sorites SSA). For each sub-scheme we propose critical questions, as well as four rules that (...) clarify when the SSA scheme is used reasonably. The institutional preconditions make the analogical SSA expectable in common law contexts; the Sorites SSA is expectable in civil law contexts; whereas the causal SSA is common to both contexts. This result should inform future work on the identification of typical argumentative patterns for the SSA in legal contexts. (shrink)

While courts depend on expert opinions in reaching sound judgments, the role of the expert witness in legal proceedings is associated with a litany of problems. Perhaps most prevalent is the question of under what circumstances should testimony be admitted as expert opinion. We review the changing policies adopted by American courts in an attempt to ensure the reliability and usefulness of the scientific and technical information admitted as evidence. We argue that these admissibility criteria are best seen in a (...) dialectical context as a set of critical questions of the kind commonly used in models of argumentation. (shrink)

The aim of this paper is to analyse the legal record on civil litigation from mid-March 2020 to mid-July 2021 and examine COVID-19 pandemic-related arguments in a sample of litigated cases heard in Polish courts, more precisely 41 cases. In an attempt to establish the number and types of court cases in which such arguments have been raised, the population of individual case records was accessed electronically from the Ordinary Courts Judgments Portal. The analysed research material consists of texts of (...) written justifications published along with rulings of courts of the first instance in the Portal, except for texts regarding criminal cases and widely understood labour cases. This paper refers to certain theoretical aspects of argument and argumentation. Then, it sheds light on the use of COVID-19 pandemic-related arguments by the parties involved in litigation—as reported by the courts in written justifications—considering, amongst others, whether those arguments were found convincing by the courts. Based on a survey of relevant cases, an attempt was made to identify categories of COVID-19 pandemic-related arguments of the parties involved in litigation, raised in their legal submissions. Also a look into the tendencies in this regard was taken to see whether any patterns emerge and it is possible to discern different trends in the analysed phenomena. The point of the analysis in this article is both descriptive and normative. (shrink)

Certainly principles of criminal liability may be understood as rules or norms outlining orders or prohibitions and standing out among other norms with their weight, for legal culture, legal doctrine, etc. In such a classic approach they are norms defining basic rights and obligations in the applicable criminal law. However, is it the only possible and cognitively interesting meaning of the word “principle” in jurisprudence? From the semiotic point of view, they can occur in three forms: special-kind norms, teleological directives, (...) rules which constitute valid performance of conventional activities. In an extra-directival sense these principles may be understood as models-descriptions of shaping the system of criminal law. From a theoretical and practical point of view principles addressed to the legislator are extremely weighty—they can be called rules constructing the system of criminal liability. These all problems are discussed in the article. (shrink)

This paper aims to perform a multi-level analysis of the Irish public discourse on Covid-19. Despite widespread agreement that Ireland’s response was rapid and effective, the country’s journey through the pandemic has been no easy ride. In order to contain the virus, the Government’s emergency legislation imposed draconian measures including the detention and isolation of people deemed to be even “a potential source of infection” and a significant extension of An Garda Síochána’s power of arrest. In April 2020, journalists John (...) Waters and Gemma O’Doherty initiated judicial review proceedings before the High Court to challenge such legislation, which they defined as unconstitutional, “disproportionate” and based on “fraudulent science”. The proceedings attracted widespread media coverage in what soon became a debate on the legitimacy of emergency legislation and the notion of ‘fake news’ itself. After a brief survey of the legislative background to Ireland’s Covid response, the argumentative strategy is analysed through which the High Court eventually dismissed Mr Waters and Ms O’Doherty’s challenge. Focusing on the process of justification of the judicial decision, the paper provides a descriptive account of the argument structure of the Court’s decision. This sheds light on the pattern of multiple argumentation through which the Court interpreted relevant norms in the Constitution and at once re-established the primacy of “facts” informing political decision-making at a time of national emergency.

A contrario reasoning (or ‘a contrario argument’ or ‘argument a contrario’) is traditionally understood as an appeal to the deliberate silence of the legislator: because a legal rule does not mention case X specifically, the rule is not applicable to it. Modern perspectives on legal reasoning often apply this label to a broader concept of reasoning, namely the reasoning by which a legal rule is not applied because of the differences between the case at hand and the one(s) mentioned in (...) the legal rule. This article first explains how the broader concept could have come into being, and then argues that from an argumentation theoretical point of view the modern concept makes no sense as a category of argumentation. Furthermore it is shown under which conditions the traditional concept can be sound. (shrink)

SummaryThis contribution offers an evaluation of e contrario reasoning in which the interpretation of a legal rule is based on the context of the law system (contextual e contrario reasoning). A model is presented which will show all the explicit and implicit elements of the argument at work and will also point out how these distinct parts are interrelated. By questioning the content and justificatory power of these elements, the weak spots in the argument can be laid bare. It will (...) be argued that e contrario reasoning inevitably requires a dubious argumentative step, which renders the argument intrinsically weak. The model is applied to a European lawsuit on French cheese. (shrink)

This paper is concerned with argumentation in legal proceedings, namely in criminal cases. My interest is to explore how in the legal realm different argumentation fields interact, the juridical field being just one of them. The paper lays out an approach of studying argumentation in the legal realm in the framework of an ethnographic methodology by identifying the “topical rules” the participants in criminal trials adhere to. Suggesting the notion of field-dependence as a good starting point for the analysis of (...) legal argumentation, I will give several examples of different fields of argumentation interacting in criminal proceedings. The examination of what counts as a good reason and how arguments are employed, negotiated, and evaluated within a criminal proceeding might shed light on the practice of constructing facts and arriving at decisions in court. It can furthermore point at the constitution of legal rationality and how it is produced in criminal trials. I argue that rationality in criminal proceedings is interactively accomplished by negotiating different standards of validity. (shrink)

Identifying, classifying, and analyzing arguments in legal discourse has been a prominent area of research since the inception of the argument mining field. However, there has been a major discrepancy between the way natural language processing (NLP) researchers model and annotate arguments in court decisions and the way legal experts understand and analyze legal argumentation. While computational approaches typically simplify arguments into generic premises and claims, arguments in legal research usually exhibit a rich typology that is important for gaining insights (...) into the particular case and applications of law in general. We address this problem and make several substantial contributions to move the field forward. First, we design a new annotation scheme for legal arguments in proceedings of the European Court of Human Rights (ECHR) that is deeply rooted in the theory and practice of legal argumentation research. Second, we compile and annotate a large corpus of 373 court decisions (2.3M tokens and 15k annotated argument spans). Finally, we train an argument mining model that outperforms state-of-the-art models in the legal NLP domain and provide a thorough expert-based evaluation. All datasets and source codes are available under open lincenses at https://github.com/trusthlt/mining-legal-arguments. (shrink)

A generation before Beardsley, legal scholar John Henry Wigmore invented a scheme for representing arguments in a tree diagram, aimed to help advocates analyze the proof of facts at trial. In this essay, I describe Wigmore's "Chart Method" and trace its origin and influence. Wigmore, I argue, contributes to contemporary theory in two ways. His rhetorical approach to diagramming provides a novel perspective on problems about the theory of reasoning, premise adequacy, and dialectical obligations. Further, he advances a novel solution (...) to the problem of assessing argument quality by representing the strength of argument in meeting objections. (shrink)

There are many different ways in which modern Corpus Linguistics can be used to enrich and broaden our understanding of legal discourse. Based on the central principle of co-occurrence and co-selection in language construction, this paper reviews current applications of Corpus Linguistics in the area of legal discourse focusing on issues ranging from phraseology, variation in legal discourse, legal translation, register and genre perspectives on legal discourse, legal discourse in forensic contexts to evaluative language in judicial settings. It revisits the (...) notion of ‘corpus’ and it highlights the relevance of various types of legal corpora and computer tools in legal linguistic research. (shrink)

The article develops and justifies, on the basis of the epistemological argumentation theory, two central pieces of the theory of evaluative argumentation interpretation: 1. criteria for recognizing argument types and 2. rules for adding reasons to create ideal arguments. Ad 1: The criteria for identifying argument types are a selection of essential elements from the definitions of the respective argument types. Ad 2: After presenting the general principles for adding reasons (benevolence, authenticity, immanence, optimization), heuristics are proposed for finding missing (...) reasons, for deductive arguments, e.g., semantic tableaux are suggested.

We intend to examine ways that emotions may be intertwined within argumentative legal discourses. From the transcript of a brief trial in a Court of Appeal in Brazil we have the opportunity to observe how the emotional and rational reasoning live together in a deliberation among magistrates. “The leg broken case” allow us to examine how judges define the value of compensation to be paid in cases of moral damage. We show that not only technical arguments are the compounds of (...) one decision; subjectivity is also important in that legal context. We would yet confirm what jurists and philosophers of the argumentation fields, such as G. Cornu, E. Feteris, A. Garapon, J. J. Robrieux, C. Perelman, C. M. Stamakis, among others, had already emphasized: judges are not cold machines in the moments of a judging. The analysis may show that a sentence is a mix of legal rules and magistrates’ personal experience, in some extent. (shrink)

I give a pragma-dialectical reconstruction of the role of teleological-evaluative argumentation referring to goals and values in the justification of judicial decisions. I establish the role and place of this form of argumentation in complex forms of justification in which the argumentation interacts with other forms of legal argumentation. I will do this by integrating the insights from legal theory and legal philosophy into a pragma-dialectical framework for the analysis and evaluation of argumentation.

Van Eemeren and Houtlosser concentrate on the tension inherent in argumentative discourse between the pursuit of success and the maintenance of reasonableness. They elaborate on their earlier claim that this tension leads to ‘strategic manoeuvring’ that can be explained by making use of insights from dialectic and rhetoric. As a new step in their treatment of strategic manoeuvring they take account of the fact that the manoeuvring always takes place in one of the various argumentative ‘activity types’ that can be (...) distinguished in argumentative practice. Unlike theoretical constructs such as a critical discussion and other ideal models, which are based on analytic considerations regarding the most pertinent presentation of the constitutive parts of a problem-valid procedure for carrying out a particular kind of discursive task, the activity types and their associated speech events are cultural artefacts that can be identified on the basis of careful empirical observation of argumentative practice. By concentrating on three conventionalised activity types that are more or less institutionalised, van Eemeren and Houtlosser show how strategic manoeuvring is affected by the opportunities and constraints of the activity type in which it takes place.
