  Using the residual symmetry approach, we propose a complex extension of the
scaling ansatz on $M_\nu$ which allows a nonzero mass for each of the three
light neutrinos as well as a nonvanishing $\theta_{13}$. Leptonic Dirac CP
violation must be maximal while atmospheric neutrino mixing need not to be
exactly maximal. Each of the two Majorana phases, to be probed by the search
for $0\nu \beta\beta$ decay, has to be zero or $\pi$ and a normal neutrino mass
hierarchy is allowed.
