The first part of the draft is devoted to the history of teaching the philosophy of law that is organically connected with natural law, which disappeared from Polish universities and scientific literature for 40 years (1949–1989). The late 1980’s of the 20th century brought political and social transformations, and the long-awaited change in the intellectual atmosphere of the scientific and academic environment. Moreover, it brought back the philosophy of law and its subject – natural law. The second part focuses on presenting natural-law views of C. Martyniak, who, apart from his translations of the Aquinas treaty on the rights contained in the theological Summa, made a critical analysis of the definition, content and properties of natural law. The final part of the essay is an attempt to relate Martyniak’s natural law to public administration taking into account the renaissance of axiological reflection in administration and administrative law.
