(b) For purposes of this section, a pardon or a certified copy of a judgment of a court of competent jurisdiction shall be sufficient proof to the administrator that the person fulfills the above requirements as to the offense or offenses specified on the pardon or judgment; however, before allowing a person convicted of an infamous crime to become a registered voter, it shall be the duty of the administrator in each county to verify with the state coordinator of elections that the person is eligible to register under this section.

(d) The provisions of this section, relative to the forfeiture and restoration of the right of suffrage for those persons convicted of infamous crimes, shall also apply to those persons convicted of crimes prior to May 18, 1981, which are infamous crimes after May 18, 1981.
