(a) Delivery governs.--A valid military-overseas ballot cast under section 3509 (relating to timely casting of ballot) shall be counted if it is delivered by 5 p.m. on the seventh day following the election to the address that the appropriate county election board has specified.
(b) Rule regarding postmarks.--If, at the time of completing a military-overseas ballot and balloting materials, the voter has declared under penalty of perjury that the ballot was timely submitted, the ballot may not be rejected on the basis that it has a late postmark, an unreadable postmark or no postmark.
