By means of examples that illustrate the several parts of the model of legal reasoning, it is shown how RBL matches this model. Deductive logic plays a central role in legal reasoning, but logic alone cannot solve hard cases.
When we attempt to reduce the decision of a case to an argument of deductive logic, the aspects of legal reasoning that are not deductive are exposed.
