The Interrogative Model for Truth seeking (IMT) was originally developed by Jaakko Hintikka as a model to be used in science. (For an easy access to this model see [7].) Thus initial premises and presuppositions are thought of as being established theories in science and in particular that very branch of it which is under investigation at that particular time. As the focus of interest in this essay is not science but legal investigation, this model shall be extended to cover legal reasoning as well. Earlier attempts in this regard were made, e.g., in [8].
