The article refers to a construction of a control assigned to another date which occurs in provisions of substantive administrative law. The Author comes to a conclusion that use of this institution requires includ-ing and settlement of a series of issues influencing a formation of rights (obligations) of an individual. Regulation, which leaves interpretative doubts concerning the legal effectiveness of an individual's substantial-legal acts, causes that attractiveness of this legal construction is doubt-ful. The individual cannot be sure whether realisation of the rights is permissible without negative consequences. Therefore it is difficult to evaluate this construction as fully positive because from one hand it withdraws from full control, which is to simplify a procedure of acquir-ing a given type of right, however on the other hand it leaves an individ-ual's situation in postponement concerning undertaking means of con-trol assigned to another date by an appropriate organ of public admini-stration.
