Just in case anyone took this story seriously, you should know that it's a fake.
The Supreme Court typically takes months after oral argument to hand down a decision in a case. Because this case was argued just a few days ago, a decision on the merits handed down so quickly would be a real shocker. We can look for an actual decision in June.
My goal was to start the story in a plausible fashion, then pile on the absurdities. I was pretty sure that anybody who read "The First Amendment is unconstitutional" would realize that I was kidding. (The First Amendment is part of the Constitution, of course, and therefore cannot be unconstitutional.) But just in case, I included a link to an information site about April Fool jokes.
Some of the post was somewhat serious. For example, it seems to me to be a reasonable possibility that, if "under God" is allowed to remain, it might be permissible to urge school kids to sing "God Bless America" (and I wouldn't put it past some people to put pressure on public schools to do just that).
It also can happen that the Supreme Court agrees on a decision but a majority of the Court cannot agree on a rationale. In that case, the Court announces its "judgment of the Court," and the lawyers are left to puzzle over what precedents have been set. (When a majority of the Court agrees on a rationale, the Court announces its "opinion of the Court").
If this little fake story caused anyone to have a conniption or lose bowel control, then all I can say is, "April fool, ha, ha, got you!"
