  We analyze the dynamics of an $SU_L(2)\otimes U_R(1)$ chiral gauge theory on
a lattice with a large multifermion coupling $1\ll g_2 < \infty$. It is shown
that no spontaneous symmetry breaking occurs; the ``spectator'' fermion
$\psi_R(x)$ is a free mode; doublers are decoupled as massive Dirac fermions
consistently with the chiral gauge symmetry. Whether right-handed three-fermion
states disappear and chiral fermions emerge in the low-energy limit are
discussed. Provided right-handed three-fermion states disappear, we discuss the
chiral gauge coupling, Ward identities, the gauge anomaly and anomalous
$U_L(1)$ global current within the gauge-invariant prescription of
renormalization of the gauge perturbation theory.
