In the following paper sources of a constitution are put in question in general, and more specifically, the constitutional culture of the European Union Law is being investigated in-depth with regard to principles of deliberative democracy and rulings of the Court of Justice of the European Union. The change of a law application paradigm as well as the change of a legal systems’ nature are taken into account.

The main objective of the paper is to present a model of the good practices of deliberative cooperation in a parliamentary setting. This goal is achieved through applying the three functions of the deliberative system—epistemic, ethical and democratic —to an analysis of cooperation between different stakeholders during the work of a Polish Parliamentary Subcommittee. They are used as an evaluative tool for analysing the cooperation of MPs, members of the public and representatives of the government. The paper analyses a concrete (...) example of the work of the Permanent Subcommittee on the government bill amending the Act on Public Benefit Activity and Voluntary Work in the Polish Parliament. This concrete example is presented as a model of good practices when it comes to deliberative cooperation between representatives of the authorities and citizens aiming at the development of shared practical judgement. The paper consists of three parts. In the first, a systemic approach to deliberative democracy is briefly introduced, and the history of the work on the bill is outlined. The main part consists of an analysis of the three speeches of three main stakeholders in the legislative process, from the perspective of their view of legislative deliberations, and in terms of the three functions of deliberative system. In the conclusions, four main issues are analysed with reference to the presented legislative deliberations: 1. Legislative committees as mixed deliberative spheres; 2. Internal/external deliberation; 3. The distinction between stakeholders/ordinary citizens; and 4. Deliberative stance/deliberative mindset. (shrink)
