The problems of valid ity of legal norms are dealt with not only form an internal
point of view of a particular legal system , but also from an external point of view
proper to the legal theoretical research ,
The author, referring to the concepts singled out by J. Wróblewski, presents
the theoretical problems of validity using three concepts: validity (systemic validity),
efficacy (factual validity), and acceptability (axiological validity).
The author criticizes Kelson's theory of validity pointing out his linking of validity
with eflicacy . Further the dilemma of efficacy is presented considering the problem
of a judge who has to decide a case on the basis of the norm in force. The
author stresses that acceptability should be understood as a rational acceptability
conditioned by validity and efficacy of a norm.Zadanie pt. „Digitalizacja i udostępnienie w Cyfrowym Repozytorium Uniwersytetu Łódzkiego kolekcji czasopism naukowych wydawanych przez Uniwersytet Łódzki” nr 885/P-DUN/2014 dofinansowane zostało ze środków MNiSW w ramach działalności upowszechniającej naukę
