A former high school teacher who served a month in prison after being convicted of raping a 14-year-old faces more time behind bars after Montana's Supreme Court ruled Wednesday that his original sentence was too short.

Justices in a unanimous ruling ordered the case of Stacey Dean Rambold assigned to a new judge for resentencing. The decision means he must serve a minimum of two years under state sentencing laws, County Attorney Scott Twito said.

Justices cited, in part, the inflammatory remarks of the sentencing judge, District Judge G. Todd Baugh, who was widely condemned for suggesting the victim - who committed suicide while Rambold awaited trial - shared some responsibility for her rape.

Justices said they intend to deal separately with Baugh, who handed down a sentence of 15 years with all but 31 days suspended. - AP
