The subject of this article is to present the evolution of the constitutional and legal position of the Marshal of the Sejm, which covers the time from regaining independence by Poland to 1997 when the current constitution came into force. Assuming that both the scope of the competences connected with the operating of the Sejm and the powers beyond that area decide on the political position of the Marshal, the constitutional and regulatory solutions concerning that office were analysed. The result of those analyses proves that the position of the chairman of the Polish Sejm changed significantly over the analysed time. The changing political trends were the most important factor determining the constitutional and legal position of the Marshal of the Sejm. In the normative perspective they were reflected in the constitutional acts which were binding successively in Poland. The Marshal has always had the status of the constitutional body; however, this fact has not always determined his strong position in the Sejm.
