The Minnesota Supreme Court has ordered that Democrat Al Franken be certified as the winner of the state's long-running Senate race.
After the ruling, Republican Norm Coleman conceded to Franken.
The high court rejected a legal challenge from Coleman, whose options for regaining the Senate seat are dwindling.
Justices said Franken is entitled to the election certificate he needs to assume office. With Franken and the usual backing of two independents, Democrats will have a big enough majority to overcome Republican filibuster.
Coleman hasn't ruled out seeking federal court intervention.
