The proposed master Lagrangian contains the nonlocal auxiliary field and approaches self-dual formulation of Maxwell-Chern-Simons theory in a point-particle limit with the weak string-coupling limit. The consistent canonical brackets of dual system are derived.7 pages, latex, no figuresHigh Energy Physics - Theorytext
