Most of the people who make the argument I described probably believe the UN is the only legitimate body that could make this decision, based on some combination of practicality, historical precedent, and international agreement. And the UN absolutely has a mechanism for doing it (the security council). But one alternatively might argue the UN is broken/dysfunctional/corrupt enough that it can't be relied on despite having the "proper paperwork", just as national democracies can be for national affairs.
