Norm Coleman filed a lawsuit challenging the U.S. Senate recount results showing Al Franken with a 225-vote advantage.

WHY DO IT?

"We are filing this contest because it has to be clear that every valid vote was counted and no one's vote was counted more than someone else's," he said.

WHO DECIDES?

The "election contest" will be presided over by a three-judge panel named by senior Supreme Court Justice Alan Page. Chief Justice Eric Magnuson recused himself, because he served on the Canvassing Board.

WHEN?

The election contest is expected to begin within 20 days.
