TY - JOUR TI - On Radbruch’s formula AU - Woleński, Jan TI - On Radbruch’s formula AB - The aim of this article is to analyse Radbruch’'s formula (lex iniustissima non est lex) with regard to the notions it contains and to indicate that it expresses a basic problem of philosophy of law linked to the discussion between legal positivism and the doctrines of natural law. That analysis underpins the proposal for a possible  rational compromise between the two standpoints. The main problem in the dispute between the rival doctrines amounts to the adoption of some material criterion for defining gross injustice, whilst the background to the dispute is the functioning of the principle which states that law is not retroactive.
