The Theoretical Value of the Category of Second Rights for the Russian Legal Science

The article deals with the category of secundary rights introduced into scientific circulation by Emil Zeckel in the early XX century. Recently, the mentioned category has become widespread in Russian legal science and is used to justify various legal ideas. The article notes, meanwhile, that the theory of secundary rights is a subject of disputes in science and has not yet received a level of scientific development sufficient to formulate abstract rules of behaviour common to all legal phenomena covered by the concept, which is ultimately the purpose of any legal construction. At the same time, the value of the concept of secundary rights for the purposes of obtaining knowledge useful in applied and theoretical terms is questioned.
