  The normal-state resistivity of the cuprate superconductors is metallic in
the $ab$ plane but is characteristic of an insulator along the $c$ direction,
leading to the possibility of the remarkable phenomenon of confinement. By
continuity, such a behavior is not expected to occur in a Fermi liquid. We
consider the anisotropic $t$-$J$ model with the c-axis parameters $t_c$ and
$J_c$ different from their in-plane counterparts, $t$ and $J$. Within the
slave-fermion mean-field approximation it is shown that the spiral state
exhibits charge-confinement in the intermediate $\delta$ regime for a range of
values of $t_c/t$. In the confined state the hopping amplitude
$<c^{\dag}_{i\sigma}c_{j\sigma}> = 0$ along the c direction so that c-axis
resitivity is infinite at $T = 0$.
