The Construction of the Thetic Acts by Czesław Znamierowski

Abstract

Czesław Znamierowski created the concept of thetic acts, which by European standards at the time, was an original theoretical model in legal theory. He based it on the observations that there are suchlike human actions that do not cause effects of physical consequence of the same action e.g. such as making a promise, making a will, a sale or other legal acts. This article compares this concept with a concept based on similar observations i.e. the concept of conventional actions created by Zygmunt Ziembiński and his team. The connection between these concepts is not obvious, even though both were created by the Poznan Centre of Legal Theory. This article will explore the question whether the concept of conventional actions is a development of the concept of thetic acts, or whether it is purely a concept based on similar assumptions that genetically constituting a separate theoretical model.
