The following is a list of cases that I have compiled that have relevance to the topic of separation of Church and State. A number of these aren’t specifically SoCS cases, but they do deal greatly with either the establishment clause or the free exercise clause of the first amendment. As such, I consider them pertinent to the discussion.
