A federal appeals court has revived a lawsuit against Muskingum College. A former professor, Betsy Nichols sued Muskingum College after it failed to renew her teaching contract for the 1998-99 academic year. She then filed a discrimination complaint. The sixth U-S circuit court of appeals said a lower court erred two years ago when it dismissed Nichols’ lawsuit. The case now goes back to Columbus federal judge George Smith for reconsideration.
