If you look at the court system since the nation was founded, you will notice that the most cockamamie decisions are subsequent to Roosevelt's appointments. One of the most insane rulings by the Supreme court, Wickard v Fullburn (A farmer can't grow his own wheat to feed his own cows) was entirely decided by Roosevelt appointed Judges.
Prayer in Schools? Something which had been going on since BEFORE the nation was founded? According to the Roosevelt/Truman judges, it was a violation of the 14th amendment!
Loons, all.
There was still one Hoover appointment on the bench at that time, Owen Roberts. He joined the others in a unanimous decision.
