The direct application of the constitutional provisions gives rise to many problems due to the particularities involved. These problems can be encountered not only in a judicial, but also in a managerial type of law application. Within the framework of the last model, the application of the constitutional provisions has to be considered through the Sejm of the Republic of Poland. The constitutional law focuses on the institutions of the political system.It determines the structure, functions, the competencies and the relationship between them. Taking into consideration the fact that the parliament has an important influence on the functioning of governance, the issue of the direct application of constitutional provisions by that authority is taking on new significance. The issue of the application of the constitutional rules relating to the Sejm internal organisation and its political functions has to be considered as relevant. The order of the direct application of the constitution indicates not only the necessity of application of the regulations, which define its organisation, operation and the subject of activity, but also these, which express so-called principles and values. Their full normative content is generally determined in jurisdiction of Constitutional Tribunal, which in turn obliges the Sejm and its authorities to apply these regulations in a manner which takes into account the judicial acquis of this organ.
