Leptogenesis without CP Violation at Low Energies

In this letter we give a class of examples where the decays of the heavy Majorana neutrinos may violate CP even if there is no CP violation at low energies, i. e., leptogenesis can take place without Majorana or Dirac type CP phases at low energies.
