  We construct a Fermi liquid theory to describe transport in a
superconductor-quantum dot- normal metal junction close to the singlet-doublet
(parity changing) transition of the dot. Though quasiparticles do not have a
definite charge in this chargeless Fermi liquid, in case of particle-hole
symmetry, a mapping to the Anderson model unveils a hidden U(1) symmetry and a
corresponding pseudo-charge. In contrast to other correlated Fermi-liquids, the
back scattering noise reveals an effective charge equal to the charge of Cooper
pairs, $e^* = 2e$. In addition,we find a strong suppression of noise when the
linear conductance is unitary, even for its non-linear part.
