[en] In this paper, the authors argue on the basis of dual models, supplemented by Schwimmer's analysis that all nice features of resonance-Regge pole duality requires the non-existence of C-exotic mesons, that indeed such states are likely to be absent in the energy domain approx-lt 1.6 GeV where duality has been successfully tested experimentally. The status of the experimental C-exotic 1^minus-plus candidate M(1405) is examined further. Evaluation of methods for experimental search of this class of states is also briefly discussed
