  The Israel junction conditions of a thin shell in the context of
Einstein-Cartan gravity are revisited. It is shown that with a choice of the
torsion discontinuity taken to be orthogonal to the hypersurface and consistent
with the antisymmetric properties of torsion tensor and contorsion tensor, the
generalized asymmetric surface energy-momentum tensor turns out to be tangent
to the hypersurface while the resulting generalized Israel junction conditions
are modified. The main differences to previous works are mentioned.
