Abstract Seeing that socio-legal theory has produced a number of compelling
grand theories about law's development as a body of knowledge, this contribution
analyzes legal evolution on the micro-level of decision-making in concrete cases.
To that end, law finding is reconstructed as a three stage process of reason-based
rule-construction. Legal evolution is argued to stem from the argumentative jumps
that are made in this process in order to use what is initially drawn from the body of
legal knowledge in new cases. These jumps are justified by additional reasoning that
plays a crucial role in that it brings new information to the law finding process. It is
explained how this new information gets incorporated in the body of knowledge as a
result of discursive maneuvers of legal practitioners.

1 Introduction
Socio-legal theory has produced a variety of compelling accounts of law's development
as a body of knowledge. Max Weber famously contended that law emerges and
develops in an interplay between formal and substantive rationality. On the one hand, he
argued that modern law is characterized by devotion to generalization and systemati-
zation, that is, by the picture of law as a logically organized set of applicable rules. On
