Nevada's "mailbox deadline," allows mail ballots received up to four business days after Election Day to be counted to account for practical shortcomings of USPS policies and practices. For example, postmarks are not required on all mailings and are designed to prevent reuse of postage and mail ballot postmarks may become smudged or illegible. To prevent arbitrary disenfranchisement of voters, mail ballots received by 5 p.m. on the third day after election day that are not clearly postmarked by Election Day are still counted.
The Republican National Committee (RNC) claims that this deadline violates federal law because there is only one specific day recognized by federal law as the national election day. We filed an amicus brief asking the court to dismiss the case as Nevada's "mailbox deadline," is a valid exercise of the state's delegated authority over federal elections by the Electoral Count Reform Act which does not prohibit state laws that allow for timely cast ballots to be received and counted in the days following the election. Furthermore, there are also no federal laws prohibiting or conflicting with Nevada's Mailbox Deadline Laws.
