DENVER – A federal court has ruled that a Colorado school district violated the Constitution when it supported a Christian spring break mission trip in 2014.

The Denver Post reports a parent and the American Humanist Association filed a lawsuit against the Douglas County School District after it supported the trip to Guatemala by a group of students from Highlands Ranch High School’s chapter of Fellowship of Christian Athletes.

U.S. District Court Judge R. Brooke Jackson wrote in the opinion that the district backed an “overtly Christian cause through financial donations, through sending emails and flyers to students’ families, and through hosting the supply drive during school hours over the course of a school week,” resulting in “an excessive government entanglement with religion.”

The district hasn’t responded if it intends to appeal.
