The supreme courts ruling in engle vs. vitale?

It was a landmark United States Supreme Court case that ruled it is unconstitutional for state officials to compose an official school prayer and encourage its recitation in public schools.

In an opinion delivered by Justice Hugo Black, the Court ruled that government-written prayers were not to be recited in public schools and were a violation of the U.S. Constitution and the Establishment Clause of the first amendment. This was decided in a vote of 6-1.
