Abstract. Rights of the citizen as a party in the administrative proceeding to access information. The article discusses rights of the citizen as a party in the administrative proceeding to access information on the factual and legal status of the proceeding held by a public administration institution. Given the inquisitional character of administrative proceedings, the release of information mainly lies with the public administration authority as the exclusive body to hold such proceedings. As practice indicates, adequate access to reliable information often determines the scope of the procedural powers of parties. The discussion presented in the article concerns statutory regulations enabling access to information as provided in the Constitution of the Republic of Poland and in the code of administrative proceedings.
