Applying a master action technique we obtain the dual of the noncommutative
Maxwell-Chern-Simons theory. The equivalence between the Maxwell-Chern-Simons
theory and the self-dual model in commutative space-time does not survive in
the non-commutative setting. We also point out an ambiguity in the
Seiberg-Witten map.Comment: 10 pages; Fifth International Conference on Mathematical Methods in
