  We compute the Lema{\^i}tre-Hubble diagram for axial Bianchi IX universes
with comoving dust. We motivate our choice by defining a {\it minimal} symmetry
breaking of the cosmological principle. This criterium admits only two
possibilities: the axial Bianchi I and IX universes. The latter have positive
curvatures and reduce to the former in the zero curvature limit. Remarkably,
negative curvatures are excluded by this minimal symmetry breaking in presence
of comoving dust.
