  We present a new method for regularizing chiral theories on the lattice. The
arbitrariness in the regularization is used in order to decouple massless
replica fermions. A continuum limit with only one fermion is obtained in
perturbation theory and a Golterman-Petcher like symmetry related to the
decoupling of the replicas in the non-perturbative regime is identified. In the
case of Chiral Gauge Theories gauge invariance is broken at the level of the
regularization, so our approach shares many of the characteristics of the Rome
approach.
