We revisit the contribution of the QCD \(\bar \theta\) term to the CP violating pion-nucleon couplings and the nucleon electric dipole moment in a combined large-\(N_c\) and chiral perturbation theory framework. In particular, we approach this issue through the emergent spin-flavor symmetry of the baryon sector at large but finite \(N_c\). We obtain good agreement with previous analyses for the pion-nucleon couplings and show that the large-\(N_c\) framework indicates that tree-level contributions to the electric dipole moment possibly play a dominant role. The spin-flavor symmetry also enables us to provide novel constraints on CP violating pion-\(\Delta\) couplings as well as the \(\Delta\) electric dipole moment and \(\Delta N\) transition moment.
