The (Lancaster) Intelligencer Journal/Lancaster New Era says a state Superior Court overturned the Lancaster County convictions and 20- to 40-year sentence of 35-year-old Christy Lee Smith.
Police said the teens were 15 and 17 at the time of the alleged relationships from 2008 to 2010, and one met the former McCaskey High teacher at school and the other at a dance class.
Smith was also charged with child pornography in connection with photos of the older youth. The appeals court ruled that the two cases shouldn't have been tried at the same time.
Prosecutors say they will decide whether to appeal or proceed with a retrial.
