MINNEAPOLIS, Minnesota (CNN) - Attorneys for Norm Coleman announced Monday afternoon they have filed an appeal seeking to overturn a District Court's decision that he lost his bid for re-election to the U.S. Senate last November.
The appeal, filed with the Minnesota Supreme Court, followed the lower court's ruling that Democrat Al Franken beat Coleman, a Republican.
"We do believe that the District Court got it wrong on the law and wrong because the Minnesota tradition and law are to enfranchise people, and their decision disenfranchises many Minnesotans whose votes have been wrongly rejected," said Coleman attorney Ben Ginsberg.
Last week, a three-judge panel ruled Coleman did not prove his key argument, which is that potentially thousands of voters' absentee ballots were wrongly rejected because of inconsistencies among counties.
Ginsberg added that the court will set a briefing schedule, after which the campaign will file a full brief "according to what the court orders."
Attorney Jim Langdon said he expects oral arguments to begin "somewhere between two weeks and two months" from now.
