10-109 - Military Voters; Cancellation of Registration.

  10-109.  Military  voters;  cancellation of registration. 1. Voters
  registered pursuant to this article shall be eligible to vote  in  every
  election  in  which  military  voters are eligible to vote which is held
  more than ten days after the date of the receipt of  their  applications
  for such registration.
2.  If  any  ballot, application form or other mail sent to a military
  voter at his military address by the board of elections is  returned  by
  the post office as undeliverable, the board of elections shall ascertain
  whether  the  military  voter  is  residing  at the address given on his
  registration records as his permanent address. If he is residing at such
  address, the board shall not  send  him  any  further  military  ballots
  unless  he  applies  for  them in the regular way, giving a new military
  address. If such military  voter  is  not  residing  at  such  permanent
  address, the board of elections shall send a confirmation notice to such
  military  voter  at his last military address pursuant to the provisions
  of section 5-712 of this chapter and shall  place  the  registration  of
  such  voter  in inactive status.   However, if such a voter notifies the
  board of elections that he has moved to  a  new  military  address,  the
  board  shall  restore the registration of such voter to active status in
  the manner prescribed by section 5-213 of this chapter.
3. The board of elections shall process and preserve  the  records  of
  such   registrations,  including  the  original  applications  for  such
  registrations, in the same manner and for the same period of time as the
  records  of   other   voters   registered   under   permanent   personal
  registration.
4.  A  military  voter whose registration is cancelled pursuant to the
  provisions of section  5-400  of  this  chapter  shall  be  eligible  to
  reregister in the manner provided by this article.
5.  Upon  cancelling  the registration of a military voter pursuant to
  the provisions of section 5-400 of this chapter, the board of  elections
  shall  forthwith  notify  such voter at his last military address and at
  his permanent residence address of the fact  of  the  cancellation,  the
  reason  therefor,  and  of  his  right  to  reregister  pursuant to this
  article.
