"Apparently first of its kind" just means the reporter who wrote the story couldn't find any similar or related cases after their brief perusal of an internet site providing SCOTUS opinion records and/or a Google search.
You're giving the "reporter" from World Nut Daily entirely too much credit. WND isn't a news source in any use of the word. It's a propaganda tool for right wingnuts who want to get the rest of us to believe there's a vicious war against fundamentalist Christianity. I seriously doubt the "reporter" knows the first thing about First Amendment history, he simply thought it would make things sound more dire if he said "Apparently first of its kind."
