The legality of the succession has been questioned by international lawyer Yehuda Z. Blum, who opined that "with the demise of the Soviet Union itself, its membership in the UN should have automatically lapsed and Russia should have been admitted to membership in the same way as the other newly-independent republics (except for Belarus and Ukraine)." The elimination of Soviet (and subsequently Russian) membership on the UN Security Council would have created a constitutional crisis for the UN, which may be why the UN Secretary-General and members did not object. This situation could have been avoided had all the other nations but Russia seceded from the USSR, allowing the USSR to continue existing as a legal entity.
