Pseudoclassical supersymmetrical model to describe massive spin-one pa
rticles in (2 + 1) dimensions is proposed. A quantization of the model
leads to the theory of Chern-Simons particles. In particular, one can
see that the equations of the topologically massive gauge theory are
reproduced in the course of quantization. For comparison a pseudoclass
ical model for Proca particles in (2 + 1) dimensions is constructed an
d discussed.
