Abstract: | The purpose of this paper is to demonstrate that Neil MacCormick’s conception of norm-usage makes it necessary to address the concept of the public power of judgement as the key concept for understanding the democratic legitimization of current law. Therefore, firstly I analyse MacCormick’s conception of norm-usage, secondly I demonstrate that it leads to the idea of the institutionalisation of judgemental–interpretative practice, and thirdly, I show that the latter paves the way to the public power of judgement. Finally, I argue that this power needs to be elaborated in terms of competencies which are broader than legal skills and legal reasoning, and, further, that these competencies condition the use of both legal skills and reasoning. Importantly, MacCormick’s contribution to understanding the public power of judgement—when further developed—may indicate the profound role of comprehending the proper significance of law in a democratic polity and its relationship to the citizenry. |
