In this contribution the prototypical argumentative patterns are discussed in which pragmatic argumentation is used in the context of legal justification in hard cases. First, the function and implementation of pragmatic argumentation in prototypical argumentative patterns in legal justification are addressed. The dialectical function of the different parts of the complex argumentation are explained by characterizing them as argumentative moves that are put forward in reaction to certain forms of critique. Then, on the basis of an exemplary case, the famous Holy Trinity case, the way in which the U.S. Supreme Court uses pragmatic argumentation in this case is discussed by showing how the court instantiates general prototypical argumentative patterns in light of the institutional preconditions of the justification in the context of the specific case.

In this article the author develops a framework for a pragma-dialectical reconstruction of teleological argumentation in a legal context. Ideas taken from legal theory are integrated in a pragma-dialectical model for analyzing and evaluating argumentation, thus providing a more systematic and elaborate framework for assessing the quality of teleological arguments in a legal context. Teleological argumentation in a legal context is approached as a specific form of pragmatic argumentation. The legal criteria that are relevant for the evaluation of teleological argumentation are discussed and translated in terms of critical questions that are relevant for the evaluation of the various forms of teleological argumentation.
