We analyse the pure Chern-Simons theory on an Euclidean infinite lattice. W
e point out that, as a consequence of its symmetries, the Chern-Simons theo
ry does not have an integrable kernel. Due to the linearity of the action i
n the derivatives, the situation is very similar to the one arising in the
lattice formulation of fermionic theories. Doubling of bosonic degrees of f
reedom is removed by adding a Maxwell term with a mechanism similar to the
one proposed by Wilson for the fermionic theories.
