This article utilises Luhmann's functional analysis to investigate the role played by legal argumentation within the legal system. Luhmann's sociological observations on this subject suggest an alternative to jurisprudential approaches that understand legal arguments and consequent decisions in terms of the relative strengths of the justifications offered in their support. His account examines the role played by legal argumentation in allowing the legal system to evolve in response to society's increasing complexity. The concepts he employs to analyse this evolutionary capacity (...) of law, developed from their origins in information theory, are redundancy and variety. Beginning with the work of Dworkin the article opens up Luhmann's analysis to consider how legal argumentation operates both as a grounded form of communication, capable of identifying weak or unsustainable interpretations of legal texts, and a mechanism for evolving law in the direction of increasing complexity.

This work represents Niklas Luhmann's definitive application of systems theory to the understanding of law. In it Luhmann reviews past attempts to create a theory of law and argues they all fail to capture how law operates in modern society. He presents an alternative, critical theory through analysing law as a system of communication.

Time is central to Luhmann’s writings on social systems. Social systems, as systems of meaning, operate within three dimensions: factual, social and temporal. Each of these dimensions entails selections of actualities from potentialities (or contingencies) within horizons. Whilst the factual dimension involves selections based on distinguishing ‘this’ from ‘something else’, and the social distinguishes between alter and ego (asking with respect to any meaning whether another experiences it as I do), the temporal dimension operates with the primary distinction of before (...) and after. In the temporal dimension, everything is ‘ordered only according to the when and not to the who/what/where/how of experience and action’ (Luhmann in Social systems. Stanford University Press, Stanford, 1995, p. 78). In this paper, we explore the connection between the temporal dimension of meaning within the legal system and its connection to justice. We begin by setting out succinctly the role played by justice within the legal system, as presented by Luhmann, particularly in his book Law as a social system (2004). From this beginning, we move on to consider the relationship between law, justice and time, taking two examples. The first is the temporality of judicial decisions. The second concerns the relationship between the temporal meaning of law’s own operations, and the presumption of innocence. (shrink)
