Abstract

The present work shows how the analysis of the valuation of the proof, using tools of plot diagramming, can help the juridical operators to evaluate the quality of the argumentation of the juridical reasoning. There is applied the Modified Wigmorean Analysis (MWA) to a penal hypothetical case and to a real case, testing the process of analysis and diagramming and proving his utility. The conclusion outlines the advantages and weaknesses of the analysis and suggests adjustments to the process of diagramming.
