Whenever a registered voter is alleged to be improperly registered, except for reason of removal of residence from the precinct, either by the general registrar or by any three qualified voters of the county or city who make such an allegation to the general registrar, the registrar shall post at the courthouse or publish in a newspaper of general circulation in his county or city the name of the registered voter on a list of persons whose registrations are to be cancelled by the general registrar. The list shall be certified by the registrar and delivered or sent by mail to the county or city chairman of each political party. If sent by mail, the general registrar shall obtain a certificate of mailing. In addition to the posted or published list, the general registrar shall send a notice by mail to the last known address of each registered voter on the list, stating the reasons provided by law for the cancellation, the facts on which the cancellation is based, and when the registrar, at his office during regular office hours, will hear testimony produced for or against the right of persons named in the notice to be retained on the registration records. The hearings shall be held not less than ten days after the mailing of the notice, and in no event shall be within sixty days of the general election in November or within thirty days of any other election in the county or city. At the hearing, the registrar shall hear the testimony produced and shall determine if the registered voter named in the notice is qualified to vote in the county or city. If the person is no longer qualified to vote, the registrar shall cancel the voter’s registration. Nothing contained in this section shall prevent the registered voter from applying to the general registrar for a transfer to his proper jurisdiction, provided the registration records are not closed as provided by law. The general registrar may continue the hearing for a period of not more than thirty days in order to complete his examination. If the registered voter so challenged fails to appear and defend his right to be registered, his registration shall be cancelled by the general registrar.
