symmetric (with the possibility of an asymmetric configuration) federation asymmetric model federal constitution
Russia, by 1993 constitution, is a symmetric (with the possibility of an asymmetric configuration) federation. Unlike the Soviet asymmetric model of the RSFSR, where only republics were "subjects of the federation", the current constitution raised the status of other regions to the level of republics and made all regions equal with the title "subject of the federation". The regions of Russia have reserved areas of competence, but no regions have sovereignty, do not have the status of a sovereign state, do not have the right to indicate any sovereignty in their constitutions and do not have the right to secede from the country. The laws of the regions cannot contradict federal laws.
