We show that the excess in the \(pp \to ee jj\) CMS data can be naturally interpreted within the Minimal Left Right Symmetric model (MLRSM), keeping \(g_L = g_R\), if CP phases and non-degenerate masses of heavy neutrinos are taken into account. As an additional benefit, a natural interpretation of the reported ratio (14:1) of the opposite-sign (OS) \(pp\to l^\pm l^\mp jj\) to the same-sign (SS) \(pp\to l^\pm l^\pm jj\) lepton signals is possible. Finally, a suppression of muon pairs with respect to electron pairs in the \(pp \to lljj\) data is obtained, in accordance with experimental data. If the excess in the CMS data survives in the future, it would be a first clear hint towards presence of heavy neutrinos in right-handed charged currents with specific CP phases, mixing angles and masses, which will have far reaching consequences for particle physics directions.
