The subject of my paper is the functioning of constitutional responsibility in Poland after 1989 in its political and legal aspects. The issue which is fundamental from the point of view of the effectiveness of the state’s decision support systems is responsibility of the highest public officials. A characteristic feature of the state, which is visible irrespective of the accepted form of government, should be the shaping of the authorities responsible for the decisions made. Although the parliament assumes that the highest public officials realize the tasks that they have been entrusted with in the way that is consistent with law, at the same time – being the rational legislator – they should support their conviction with a system of legal guarantees. The latter should lead to the politically desirable goal through which the political authority is to be formed.
