Umaine fraternity Sigma Nu has been suspended for five years for what officials say was repeated violations of the student conduct code. Vice President for Student Affairs Robert Dana says the most recent incident took place on March 18th and involved underage drinking at the fraternity house on Munson Road. The chapter has seven days to appeal the decision. Dana says Sigma Nu also lost university recognition from May 2003 to September 2005 for similar conduct code violations.At the end of the suspension, the fraternity can submit a petition for reinstatement, which must be approved. Dana say 28 UMaine students are active members and 16 live in the fraternity house. Those students are being offered on-campus housing.
