Law and logic: A review from an argumentation perspective

Henry Prakken, Giovanni Sartor
2015 Artificial Intelligence  
This article reviews legal applications of logic, with a particularly marked concern for logical models of legal argument.  ...  This part of the review has special emphasis on argumentation-based approaches.  ...  For example, [140] have used the ASPIC + framework of [131, 112] to formalize argument schemes for factor-based reasoning.  ...

Argumentation and Defeasible Reasoning in the Law

Marco Billi, Roberta Calegari, Giuseppe Contissa, Francesca Lagioia, Giuseppe Pisano, Galileo Sartor, Giovanni Sartor
2021 J — Multidisciplinary Scientific Journal  
Different formalisms for defeasible reasoning have been used to represent knowledge and reason in the legal field.  ...  On top of that, two real examples in the legal domain are designed and implemented in ASPIC+ to showcase the benefit of an argumentation approach in real-world domains.  ...  This has led in particular to the development of frameworks for structured argumentation such as ASPIC+ [16] and Carneades [17, 18] , which are partially inspired by the features of legal reasoning.  ...

Some Reflections on Two Current Trends in Formal Argumentation [chapter]

Henry Prakken
2012 Lecture Notes in Computer Science  
In both cases it will be argued that the recently proposed ASPIC + framework for structured argumentation does not suffer from these limitations.  ...  This paper discusses two recent developments in the formal study of argumentation-based inference: work on preference-based abstract argumentation and on classical (deductive) argumentation.  ...  I thank all three reviewers for their many valuable suggestions and one of them in particular for triggering the discussion in footnote 10.  ...

Modeling conflicts between legal rules

Tomasz Zurek
2016 Proceedings of the 2016 Federated Conference on Computer Science and Information Systems  
The model is build on the basis of the ASPIC + argument modeling framework.  ...  The main aim of this work is to formalize the mechanism of resolving conflicts between statutory legal rules with a view to implementing them into a legal advisory system.  ...  ASPIC + argumentation framework Since the ASPIC + framework is a very powerful and useful tool for legal argumentation modeling, I am going to build the model of legal rules' conflict resolution on the  ...

of several challenges studied in deontic logic, with an emphasis on problems of multiagent deontic logic and problems related to normative systems.  ...  More information can be found in the handbook on deontic logic and normative systems, or the website In the first paper of the issue, Pigozzi and van der Torre give an overview  ...  Van der Torre and Villata [59] extend their dynamic legal argumentation framework with deontic modalities, and they propose an general framework for legal reasoning based on ASPIC-like argumentation  ...

A structured argumentation framework for detaching conditional obligations [article]

Mathieu Beirlaen, Christian Straßer
2016 arXiv   pre-print
Given a set of facts, constraints, and conditional obligations, we answer the question whether an unconditional obligation is detachable by considering reasons for and against its detachment.  ...  For the evaluation of arguments in favor of detaching obligations we use a Dung-style argumentation-theoretical semantics.  ...  For instance, the approach in [8] is based on bipolar abstract argumentation frameworks.  ...

An implementation of norm-based agent negotiation

Pieter Dijkstra, Henry Prakken, Kees de Vey Mestdagh
2007 Proceedings of the 11th international conference on Artificial intelligence and law - ICAIL '07  
In this paper, we develop our previous outline of a multi-agent architecture for regulated information exchange in crime investigations.  ...  Furthermore, the agents' negotiation policies are defined and implemented and an implementation of the agent execution cycle is proposed, which will ultimately enable us to field test our model in order  ...  Henry Prakken was also partially supported by the EU under IST-FP6-002307 (ASPIC). Our thanks goes to Matthew South for his help with the ASPIC tool.  ...

Enabling Reasoning with LegalRuleML [article]

Ho-Pun Lam, Mustafa Hashmi
2018 arXiv   pre-print
For instance, most of these formalisms do not provide features to capture the behavior of deontic effects, which is an important aspect in automated compliance checking.  ...  This paper presents an approach for transforming legal norms represented using LegalRuleML to a variant of Modal Defeasible Logic (and vice versa) such that a legal statement represented using LegalRuleML  ...  of arguments, and proposed a mapping from ASPIC + to DL.  ...
