The theory of non-monotonic reasoning has interesting applications for the formalization and automated use of legal concepts, specially:• drawing conclusions from a logically inconsistent, but hierarchic, regulations [1, 30];• similarly, establishing facts from a set of inconsistent testimonies, partially ranked by confidence;• using presumptions (such as the presumption of innocence) in the face of possibly contradictory evidence.In this paper, we use a logic [37, 38], that ranks contradictory formulae using two new paraconsistent variants of conjunction: “but” and “on the other hand”. Its algebraic proof theory is presented.
