The purpose of this paper is to address the concept of a representative parliamentary mandate in Polish tradition and in contemporary Polish constitutional law. The paper touches upon the concept of the representative mandate in the Polish constitutionalism in a comprehensive and cross-cutting manner, with regard to both former constitutional rules and the current Constitution. The considerations are based on an analysis of the normative regulations and basic doctrinal approaches. Emphasis has been also placed on the historical context of a representative mandate and on conclusions flowing from comparing the two basic models of a parliamentary mandate. The author enriches his views with references to the everyday political practice, which has a significant influence on the real perception of the notion of a representative mandate.
