After losing his case in court, former senator Norm Coleman (R) is appealing to the Minnesota Supreme Court. Coleman's brief is due April 30th. Franken then has until May 11 to respond. Coleman can file a rebuttal up until May 15. Then the lawyers will argue their cases before the five justices on June 1. Two of the seven justices have recused themselves because they served on the state canvassing board earlier in the process. So Minnesota definitely won't have a second senator until June at the earliest.
