I wouldn't say above. I would say that all states have an obligation to protect and respect human rights, and in our globalized world we're not just looking at what happens within our borders; we know that what happens within our borders is related to what happens outside of our borders.
If we are observing human rights violations occurring in other states, then yes, states can call that out. I wouldn't say it's necessarily going above the UN system, but there's nothing preventing us from having bold leadership.
