§ 11-212. Special federal ballots; deadline for receipt. All special
federal ballots received by the board of elections before the close of
the polls on election day shall be retained by the board of elections
and cast and canvassed pursuant to section 9-209 of this chapter. All
ballots contained in envelopes showing a cancellation mark of the United
States postal service or a foreign country's postal service, or showing
a dated endorsement of receipt by another agency of the United States
government, with a date which is ascertained to be not later than the
day of the election, shall be cast and counted if received by the board
of elections not later than seven days following the day of a primary
election or thirteen days following the day of a general or special
election except that the special federal ballot of a voter who requested
such ballot by letter, rather than application, shall not be counted
unless a valid application form, signed by such voter, is received by
the board of elections with such ballot. All ballots received by the
board of elections and all federal write-in ballots received from
special federal voters not later than seven days following the day of a
primary election or thirteen days following the day of a general or
special election, shall be retained at the board and shall be cast and
canvassed in the same manner as other ballots retained by such board.
