We revisit the contribution to strong CP parameter $\bar \theta$ from leptonic violation at one-loop level in minimal left-right symmetric model case of parity as symmetry. The Hermitian neutrino Dirac mass matrix $M_D$ can be calculated using light and heavy masses mixings. propose a parameterization right-handed mixing $V_R$ construct that maintains Hermiticity $M_D$. further apply it evaluate $\bar\theta$, denoted \theta_{loop}$, function sterile for explicit examples $V_R$. By requiring...
