Oregon’s vote-by-mail system will continue operating under its current ballot receipt rules after the U.S. Supreme Court ruled Monday that states have the authority to count mailed ballots that are cast by Election Day and received during a legally established grace period. The 5-4 decision in Watson v. Republican National Committee removes uncertainty for Oregon election officials and voters as preparations continue for the November 2026 general election.
The ruling centered on whether federal election law requires mailed ballots to be physically received by Election Day or whether states may continue counting ballots that were mailed on time but arrive several days later because of postal delivery. In siding with state election officials, the Supreme Court concluded that federal law allows states to recognize ballots cast by Election Day, even when those ballots are delivered afterward within deadlines established by state law.
For Oregon, the decision leaves intact a system that has become an important part of the state’s vote-by-mail process. Since 2022, Oregon law has allowed county elections offices to count ballots postmarked no later than 8 p.m. on Election Day if they arrive within seven days. Election officials say the policy helps ensure voters are not disenfranchised because of mail delays beyond their control.
Secretary of State Tobias Read welcomed the ruling, saying it protects the voting rights of Oregonians across the state.
“Today’s decision is a win for Oregon voters. The post-Election Day grace period protects thousands of Oregonians’ votes from being thrown out because of delays at the Post Office. This ruling means those legally cast ballots that arrive within 7 days of the election will be counted and those Oregonians’ voices will be heard,” Read said.
The decision carries particular importance for many communities in Southern Oregon, where residents often live considerable distances from major postal processing facilities. Ballots mailed from rural communities in Josephine, Jackson, Curry, Klamath, Lake, Douglas and surrounding counties can require additional transit time before reaching county elections offices, making the seven-day grace period an added safeguard for voters who return their ballots through the mail.
Election administrators have also pointed to ongoing changes within the U.S. Postal Service over recent years that have affected mail processing and delivery schedules in many parts of the country. Oregon officials have said the grace period helps protect legally cast ballots from delays that occur after voters have already completed and mailed them.
According to the Secretary of State’s Office, tens of thousands of ballots have been counted during Oregon’s post-Election Day receipt period over the past four years. Under state law, those ballots are treated the same as ballots received before Election Day, provided they were postmarked by the legal deadline.
Although the Supreme Court’s ruling preserves Oregon’s current election procedures, state officials continue encouraging voters not to wait until the last minute to return their ballots.
“But my advice to voters has not changed: don’t wait. Vote early and use an official drop box. If you have to return your ballot by mail, do it at least a week before Election Day, especially if you live more than 50 miles from Portland. I want every legal vote in Oregon to count. Our state is stronger when the government answers to the people,” Read said.
As Oregon moves closer to the November election, elections officials are encouraging voters to begin reviewing candidate and measure information as soon as ballots arrive. Returning completed ballots promptly or using one of the state’s official ballot drop boxes remains the most reliable way to ensure timely delivery.
Monday’s decision also provides certainty for county clerks and election administrators who have been preparing for another statewide election under Oregon’s existing vote-by-mail framework. By affirming that states may continue recognizing ballots cast by Election Day and received during lawful grace periods, the Supreme Court leaves Oregon’s election process unchanged while reinforcing the state’s authority to administer its own ballot receipt deadlines.
For Oregon voters, especially those living in the state’s rural and geographically distant communities, the ruling means the safeguards established by state law will remain in place as election officials prepare to count every ballot that is legally cast under Oregon’s vote-by-mail system.
