The Supreme Court ruled on June 29, 2026, that Mississippi can count absentee ballots postmarked by election day but received within five days afterward. This decision affects voters in Mississippi, including college students and senior citizens, who rely on absentee ballots to participate in federal elections.

The case, Watson v. Republican National Committee (docket number 24-1260), arose after the Republican National Committee and others sued the Mississippi Secretary of State, claiming that federal law prohibits counting ballots received after election day. The Court's ruling clarifies the relationship between federal election laws and state absentee voting regulations.

In Mississippi, absentee voting allows certain residents to mail their ballots, which must be postmarked by election day and received within five business days after. The plaintiffs argued that federal election-day statutes set a strict deadline for ballot receipt, while Mississippi's law allows for a grace period. The lower court initially sided with the plaintiffs, but the Supreme Court's decision reversed this ruling.

The parties involved in this case include the Mississippi Secretary of State, Michael Watson, and the Republican National Committee, along with the Mississippi Republican Party and various individuals. The dispute centers on whether Mississippi's law conflicts with federal election-day statutes that govern when ballots must be counted.

The Supreme Court, led by Justice Amy Coney Barrett, examined the federal election-day statutes and determined they do not preempt Mississippi's law. The Court stated, "The federal election-day statutes do not prevent Mississippi from counting absentee ballots postmarked by election day but received up to five days thereafter; nothing in the federal election-day statutes requires ballots to be received by election day." This ruling highlights the Court's interpretation of the term "election" as referring primarily to the act of voting, not the receipt of ballots.

The ruling emphasized that the federal statutes set the date for when voters must cast their ballots but do not dictate when those ballots must be received. The Court noted that the Uniformed and Overseas Citizens Absentee Voting Act (UOCAVA) supports this interpretation by allowing states to establish their own deadlines for ballot receipt.

The impact of this ruling extends beyond Mississippi. It reaffirms the authority of states to manage their voting processes, particularly regarding absentee ballots. This decision could encourage other states with similar laws to maintain or adopt flexible ballot receipt deadlines, thereby increasing voter participation.

The ruling also addresses concerns about election integrity and voter confidence. The Court clarified that while the plaintiffs raised valid points about the importance of timely ballot counting, these concerns are best directed to state legislatures rather than the courts. The decision underscores the balance between federal oversight and state control in the electoral process.

Looking ahead, this ruling may set a precedent for future cases involving absentee voting and election laws. It reinforces the idea that states have the power to determine their own voting procedures as long as they do not conflict with federal laws. The ruling may also influence ongoing discussions about voting rights and access to the ballot, especially as states continue to navigate the complexities of absentee voting.

As for what’s next, it is unclear if the plaintiffs will seek to appeal this decision. However, the ruling stands as a significant interpretation of election law and may have implications for related cases in the future.
