Nowadays, more and more attention is being paid to the issues of human rights. This applies not only to the first generation of human rights but also to political, economic, social and cultural rights. The guarantees for the protection and the execution of these rights should be enshrined in the provisions of the code of administrative procedure which governs proceedings before public administration bodies. However, taking into consideration today’s diverse and multicultural society, the administrative procedure seems to be not flexible enough and insufficient to ensure the protection of the constitutional rights and freedoms of foreigners. Purpose of research: The aim of this paper is to analyze the adopted procedural solutions in proceedings before public administration bodies when one of the parties is a foreigner. This paper will focus on selected institutions of the administrative procedure in the context of the protection and implementation of the fundamental constitutional rights and freedoms of every person.
