Recognition of a country does not require the security council, a general assembly vote is all that is needed. That said, the UN isn't exactly a body known for it's lawfullness or fidelity to procedure. When the UN General Secretary Ban Ki-moon rejected Taiwan's bid because of resolution 2758, there was no real legal basis for him to do that, but people just went along. Neither is there a "supreme court" of the UN that can settle these disputes, as the ICJ is intended to resolve disputes between two member nations, not disputes between the General Assembly and the Secretary General. It's best to think of the UN as a meeting place where consensus can form, rather than as a law making body with a well functioning appeal and dispute resolution process for its own deliberations.
