The Toulmin model has been proved useful in law and argumentation theory. This model describes the basic process in justifying a claim, which comprises six elements, i.e., claim (C), data (D), warrant (W), backing (B), qualifier (Q), and rebuttal (R). Specifically, in justifying a claim, one must put forward ‘data’ and a ‘warrant’, whereas the latter is authorized by ‘backing’. The force of the ‘claim’ being justified is represented by the ‘qualifier’, and the condition under which the claim cannot be (...) justified is represented as the ‘rebuttal’. To further improve the model, (Goodnight, Informal Logic 15:41–52, 1993) points out that the selection of a backing needs justification, which he calls legitimation justification. However, how such justification is constituted has not yet been clarified. To identify legitimation justification, we separate it into two parts. One justifies a backing’s eligibility (legitimation justification 1 ; LJ 1 ); the other justifies its superiority over other eligible backings (legitimation justification 2 ; LJ 2 ). In this paper, we focus on LJ 1 and apply it to the legal justification (of judgements) in hard cases for illustration purposes. We submit that LJ 1 refers to the justification of the legal interpretation of a norm by its backing, which can be further separated into several orderable subjustifications. Taking the subjustification of a norm’s existence as an example, we show how it would be influenced by different positions in the philosophy of law. Taking the position of the theory of natural law, such subjustification is presented and evaluated. This paper aims not only to inform ongoing theoretical efforts to apply the Toulmin model in the legal field, but it also seeks to clarify the process in the justification of legal judgments in hard cases. It also offers background information for the possible construction of related AI systems. In our future work, LJ 2 and other subjustifications of LJ 1 will be discussed. (shrink)

Epistemic and practical interests are often in conflict. This also occurs in institutional settings such as the legal one. Rule 407 of the U.S. Federal Rules of Evidence is an example of that because it sacrifices some epistemic interests in favour of practical ones. It is the rule on subsequent remedial measures (SRM), which is mainly designed to answer a practical concern (reducing accidents) instead of the epistemic one of getting some evidence to find out whether the defendant was negligent (...) or whether there was a defect in a product. Some commentators and courts think that the rationale of the rule is more complex and deserves a more careful discussion, as this paper shows. Additionally, this paper discusses a modification proposal (from categorical ban of SRM evidence to case‐by‐case decision) and develops some theoretical considerations, in the spirit of philosophical pragmatism, on the best way to conceptualize the problem addressed. The idea is to see such conflicts as conflicts of goals and to explain them in terms of the incompatible desires that we happen to have. (shrink)

ABSTRACTThis article defends the importance of epistemic safety for legal evidence. Drawing on discussions of sensitivity and safety in epistemology, the article explores how similar considerations apply to legal proof. In the legal context, sensitivity concerns whether a factual finding would be made if it were false, and safety concerns how easily a factual finding could be false. The article critiques recent claims about the importance of sensitivity for the law of evidence. In particular, this critique argues that sensitivity does (...) not have much of an effect on the value of legal evidence and that it fails to explain legal doctrine. By contrast, safety affects the quality of legal evidence, and safety better explains central features of the law of evidence, including probative value, admissibility rules, and standards of proof.

The aim of this paper is to show that the meaning and significance of legal evidence is being constituted throughout the course of a singular instance of legal proceedings. This is to be achieved by describing what legal agents _do_ while appealing to different propositions of fact and inferring from them throughout the course of legal proceedings. The authors claim that the process of applying the law is ultimately rooted in the inferential discursive practices of exchanging reasons on the part (...) of the participants of legal proceedings. Therefore, they set forth a model of legal proceedings that consists of an interplay between three types of reasons, which are exchanged by the participants of legal proceedings: i.e. legal reasons, epistemic reasons and stake reasons. To illustrate this interplay, the authors deploy a metaphor of law as a game, and provide a description of legal proceedings as a particular instance of playing a game of law. The conclusion is that the legal concept of evidence is (at least in part) constituted by the role that evidence plays in affecting which reasons for action the participants to legal proceedings choose to act on. The other final assumption of this paper is metatheoretical: authors want to show that when analyzing what legal evidence is, one should begin from the perspective of a singular instance of legal proceedings, rather than from the perspective of law in general.
