Legal nature and content of the concession agreement

The author convincingly proves that the concession agreement is a named (inde-pendent) civil law contract. This agreement has a detailed, detailed legal regulation. A concession agreement can be qualified as a complex agreement, since it is a complex structural (multicompo-nent) agreement. This agreement is not the result of a simple (mechanical) connection of individual components. The combination of elements generates a new phenomenon, the phenomenon of a con-tract-a system with independent (emergent) properties. It may include ordinary elements that cover, among other things, individual stages of the implementation of rights and obligations under such an agreement. In addition to the nominal elements, the concession agreement may include non-ordinary elements that are not explicitly mentioned in the provisions of the current legislation. The presence of unusual elements in the concession agreement will be the basis for its qualification as a mixed con-tract. Both named constructions of civil law contracts and unnamed contracts can act as extraordinary elements.
