Facing almost certain defeat in the Senate election trial, Norm Coleman is preparing to take his fight to the Minnesota Supreme Court.
But would that court's ruling be the final judicial word?
Maybe not. An intriguing possibility that could further prolong the Minnesota election dispute is an additional appeal to federal courts -- something supporters have repeatedly urged Coleman to consider and he has refused to rule out.
While some election law experts say it's unlikely that Coleman, a Republican, could win in federal court, his party might have much to gain. A federal challenge could leave a Minnesota U.S. Senate seat vacant for another six months or more, depriving Democrats of a vote needed to pass some of President Obama's agenda in the event of GOP filibusters.
The success of such a "scorched-earth" strategy, as one political scientist dubs a federal appeal, depends heavily on the definition of state courts.
The Minnesota Supreme Court has ruled that a Senate race winner can't be certified by Gov. Tim Pawlenty and Secretary of State Mark Ritchie "until the state courts have finally decided the election contest," as the trial was called.
If a request were made for a review by the U.S. Supreme Court, the question would be whether that "is part of that 'state contest' process so as to delay the issuance of the certificate," wrote Richard Hasen, an election law expert and professor at Loyola Law School in Los Angeles, in a recent blog for the American Constitution Society.
The answer is important because a request for a review "could take months to consider," Hasen said in an interview. He added that a petition filed after the U.S. Supreme Court's June recess might not be ruled on until October.
