The Judiciary has no power to enforce its own edicts. If the Legislative and Executive branches thumb their collective noses at the Judicial branch, what can they do?
And they know that too Al. I heard someone, probably Alan Gura, say that the court is VERY concerned about their decisions being accepted by the rest of government as they know if they put out crazy decisions they will be ignored. Seems like yet another check to their power. I think there was a more recent example of this since Jackson. The New Deal issues and Franklin Roosevelt's threat to pack the Court IIRC.
