  The massive even-parity non-Abelian gauge model in three space-time
dimensions proposed by Jackiw and Pi is studied at the tree-level. The
propagators are computed and the spectrum consistency is analyzed, besides, the
symmetries of the model are collected and established through BRS invariance
and Slavnov-Taylor identity. In the Landau gauge, thanks to the antighost
equations and the Slavnov-Taylor identity, two rigid symmetries are identified
by means of Ward identities. It is presented here a promising path for
perturbatively quantization of the Jackiw-Pi model and a hint concerning its
possible quantum scale invariance is also pointed out.
