He developed an original theory of law defined as a theory of legal phenomena, which covered both logical-linguistic as well as real aspects of law. The theory served as a base for the development of a unique so-called advanced normative conception of sources of law, one of the greatest achievements of theory of law in Poland. This conception encompasses all the indispensable elements of a coherent system of binding legal norms: 1) indication of a political justification (ideological assumptions) of the entire system of law; 2) pre-judgment of law-making competence of government agencies; 3) determination of the status of custom and precedent; 4) compilation of a catalogue of permissible interpretation rules; 5) compilation of a catalogue of permissible inferential rules (permissible rules of legal inferences); 6) compilation of a catalogue of permissible collision rules.polinfo:eu-repo/semantics/openAccesstheory of lawanalytical philosophylegal axiologylawlegal normcompetence normthetic normsaxiological normsrational legislatorvalidation rulesrules of exegesis of lawinterpretation rulesinference rulescollision rulesconventional actsArtykułhttps://doi.org/10.14746/fped.2015.4.1.12
