We suggest that the physically irrelevant choice of a representative\nworldline of a relativistic spinning particle should correspond to a gauge\nsymmetry in an action approach. Using a canonical formalism in special\nrelativity, we identify a (first-class) spin gauge constraint, which generates\na shift of the worldline together with the corresponding transformation of the\nspin on phase space. An action principle is formulated for which a minimal\ncoupling to fields is straightforward. The electromagnetic interaction of a\nmonopole-dipole particle is constructed explicitly.\n
