Georg Jellinekʼs concept of the "Normative Force of the Factual" presented in Allgemeine Staatslehre (General Theory of the State) brought me to the following question: Can a fact itself create a norm? In this paper, I will try to answer this question on the ground of three cases decided by Czech courts. In the first two cases the phrase "normative force of the factual" was actually used by a court in a reasoning of its decision.
In the third case the phrase was not explicitly used but it fits the Jellinekʼs concept. Finally, brief remarks to the normative force of factual in legal theory in general will be provided.
