  We show that the Halperin-Haldane SQHE wave function can be written in the
form of a product of a wave function for charged semions in a magnetic field
and a wave function for the Chiral Spin Liquid of neutral spin-$\12$ semions.
We introduce field-theoretic model in which the electron operators are
factorized in terms of charged spinless semions (holons) and neutral spin-$\12$
semions (spinons). Broken time reversal symmetry and short ranged spin
correlations lead to $SU(2)_{k=1}$ Chern-Simons term in Landau-Ginzburg action
for SQHE phase. We construct appropriate coherent states for SQHE phase and
show the existence of $SU(2)$ valued gauge potential. This potential appears as
a result of ``spin rigidity" of the ground state against any displacements of
nodes of wave function from positions of the particles and reflects the
nontrivial monodromy in the presence of these displacements. We argue that
topological structure of $SU(2)_{k=1}$ Chern-Simons theory unambiguously
dictates {\it semion} statistics of spinons.
