  We reexamine the idea that bilinear R-parity violating couplings can be
responsible for leptogenesis. We prove that, to have lepton number violation
before the electroweak phase transition, misalignment between the
lepton-Higgsino and slepton-Higgs sectors must be involved. The processes that
generate a lepton asymmetry are bino or wino decays into a lepton-Higgs and
slepton-Higgsino final states. Since these decays occur mainly while the
gauginos are still in thermal equilibrium, they quantitatively fail to produce
the observed baryon asymmetry of the universe.
