  We show that the quantum super-minisuperspace of N=1 supergravity with
$\Lambda \ne 0 $ has no non-trivial 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 non-trivial physical states with
a finite number of fermionic fields. We use the Jacobson canonical formulation.
