ENThe purpose of this article is to analyze the tasks of the Parliament’s Inspector (Ombudsman) in the Republic of Lithuania. The article takes into account the 2004 Act on Parliament’s Inspectors of the Republic of Lithuania, assessing the most important legal provisions contained in that act. The analysis of the tasks of the inspector of the Parliament of the Republic of Lithuania in the light of the Lithuanian act seems to be an issue worth scientific exploration. In the Polish specialist literature lacks considerations on this subject. The subject of the analysis is still a topical, because Lithuania – similarly to the countries of Central and Eastern Europe – during the political transformation established the institution of the ombudsman, which protects the rights of citizens. The research goal was achieved by using the method of institutional and legal analysis, which was helpful in the analysis of Lithuanian legal acts. Keywords: ombudsman, the Seimas Controller, Republic of Lithuania. [From the publication]
