Marc DeGirolami has a post bearing this title over at CLR Forum. The post reports on yesterday’s Fourth Circuit decision in Moss v. Spartansburg County School District Seven. Judge Niemeyer wrote the opinion for the court, in which Judge Gregory and Judge Wynn joined.
Apart from its discussion of substantive Establishment Clause principles, the opinion may be of interest for its assessment of Establishment Clause standing (an area of the law that could probably use some rethinking).
