The dynamic multiple-scattering mechanism based on classical electromagentic theory allows for the formation of non-Doppler redshifts. The mechanism deals with correlation-induced spectral changes and can produce both broadening as well as shifts of the spectral lines. In the framework described in accompanying presentations as well as previously published works (cf. S. Roy , M. Kafatos and S.Datta , Phys. Rev. A, 60, 273-279,1999; Roy S., M. Kafatos and S. Datta, A & A, 353, 1134-1138, 2000), the screening effect has been proposed using the sufficient condition for redshift. The implications for explaining the hitherto anomalous redshifts of quasars are far-reaching: In our picture, quasar redshifts are resulting from both Doppler motion of recession as well as from dynamic multiple-scattering effect. As such, in our picture, quasars would fit the overall Hubble expansion law, as galaxies do, but would also possess a "discordant" redshift component which is due to the scattering medium in the quasar vicinity itself and which dominates at high redshifts. This resolution of the paradox of quasar redshifts is much more appealing and in a sense more mainstream than either assigning quasar redshifts entirely to the Doppler effect; or inventing new, and often unknown, physical mechanisms.
