    Why Non-Monotonic Logic is Inadequate to Represent Balancing Arguments.Jan-R. Sieckmann - 2003 - Artificial Intelligence and Law 11 (2-3):211-219.
    This paper analyses the logical structure of the balancing of conflicting normative arguments, and asks whether non-monotonic logic is adequate to represent this type of legal or practical reasoning. Norm conflicts are often regarded as a field of application for non-monotonic logics. This paper argues, however, that the balancing of normative arguments consists of an act of judgement, not a logical inference, and that models of deductive as well as of defeasible reasoning do not give an adequate account of its (...)

    "Concepción Puente" y "Concepción Insular".Jan Sieckmann - 2013 - Análisis Filosófico 33 (2):211-222.
    Una concepción tradicional de la argumentación jurídica considera que se debe resolver casos jurídicos a través de subsunción y deducción. Hugo Zuleta disputa esta posición, rechazando así la "concepción puente" de las normas, la que fue defendida en particular por Carlos Alchourrón y Eugenio Bulygin. Según la "concepción puente" la norma condicional incluye una modalidad deóntica solo en su consecuencia, mientras su antecedente consiste en un enunciado descriptivo. En cambio, Zuleta propone la "concepción insular", que pone la modalidad deóntica adelante (...)

    On the Tension Between Moral Autonomy and the Rational Justification of Norms.Jan-R. Sieckmann - 2003 - Ratio Juris 16 (1):105-122.
  7. Reconstructing Relativism. An Analysis of Radbruch's Philosophy of Law.Jan-R. Sieckmann - 2009 - Archiv für Rechts- Und Sozialphilosophie 95 (1):14-27.
    This paper aims at reconstructing Radbruch's relativistic conception of law within the framework of a model of principles. The idea of relativism remains a disputed issue in current legal and moral philosophy. In spite of the fact that Radbruch's legal philosophy lacks coherence, it includes elements that resemble modern conceptions of law as a system including principles to be balanced against each other. Therefore, a reconstruction within a model of principles might as well prove the fruitfulness of the model of (...)

    Legal System and Practical Reason. On the Structure of a Normative Theory of Law.Jan-Reinard Sieckmann - 1992 - Ratio Juris 5 (3):288-307.
    It will be argued, firstly, that there is a link between the legal validity of a norm and the rational justifiability of a requirement that judges should apply this norm, based on a normative conception of legal validity and the postulate that judges should act as rational persons; secondly, that rational justifiability of legal norms requires the construction of a legal system in a model of principles that differs from theories, e.g., of Kelsen, Hart, Dworkin and Alexy, which are not (...)
