Seems that it's next-to-impossible to pass an amendment under the US system. Is it not the case that most of the existing ones were only passed either during the initial period of debate before the Constitution was even ratified, or in the aftermath of of one of the bloodiest civil wars in history?
In any case, even if an amendment were passed, would the Court not be able to effectively ignore it by constructing some nonsensical legal argument around it? As things stand it looks as if (the majority on) the Court can do whatever it wants, with no constraints at all, other than, I suppose, fear of unlawful violent reprisals.
Seems like its getting into the area of a general problem with Constitutions, and indeed all formal systems of rules.
There's no Constitution that can't be subverted. Ultimately they all depend for their stability and survival on things outside themselves (in this case, the culture and attitudes of the population, and what they are prepared to tolerate). I wonder if that is related to Godel and all that philosophical-mathematical stuff?
