Effects of Legal Revision in PROLEG

Abstract

Since interpretations of statutes develop through time, PROLEG, as a computational representation of Japanese Civil Code with rules and exceptions, also requires revisions to update represented interpretations. This paper describes effects of revisions using a responsible case assignment proposed in previous works. Based on analysis of these effects, PROLEG can remind a user to check for non-trivial effects that the user might unintentionally make during the revision.
