No quantum superminisuperspace with $\Lambda \ne 0$

We show that the quantum superminisuperspace of $N=1\mathrm{}$ supergravity with $\Lambda \ne 0$ has no nontrivial physical states for class A Bianchi models. Hence, in super quantum cosmology, the vanishing of $\Lambda$ is a condition for the existence of the Universe. We argue that this result implies that in full supergravity with $\Lambda$ there are no nontrivial physical states with a finite number of fermionic fields. We use the Jacobson canonical formulation.
