The high court ruled 6-3 in Good News Club v. Milford Central School, that the Milford, New York public school district must permit the Good News Club to conduct adult-led religious activities for grade-school children.

The court’s ruling overturned the 2nd U.S. Circuit Court of Appeals, which ruled last year that the Milford School District’s policy of barring school grounds from the use of "any individual or organization for religious purposes," did not subvert the free expression rights of the Good News Club and protected the school district from violating the separation of church and state.

"The decision threatens to open public schools all over the country to missionaries and other groups working to proselytize school children, thereby undermining the First Amendment’s separation of church and state."

Since 1996, the Good News Club, which describes itself as a community-based Christian youth group for children 6 to 12, has attempted to reserve space at a Milford school to offer after-school religious activities.

Citing its policy of barring public school space for religious proposes, Milford school officials refused the religious group’s requests.
