A Belief Revision Technique to Model Civil Code Updates

Abstract

A scenario that was not considered at the time of enforcing a civil code article may be discovered later. In case application of the civil code article in the discovered scenario is not consistent with the intention of the article, it is necessary that the article be appropriately updated. We show that this kind of civil code update that is induced upon reaction to augmentation of knowledge can be modelled in a belief revision theory. We develop our formal framework, and show one instantiation of the framework with case application of a civil code article.
