"One proposal is that it simply applies the law and the Constitution. But applying requires interrpetation when something isn't clear. Here are two views on how this can be done. One might think that when the Supreme Court interprets something wrongly it is not law and should not be followed. On the other hand, one might think that when it gets it wrong it is still binding as law until that decision gets overturned. The standard view is that the second approach is correct. If the Supreme Court decides something wrongly, we could simply ignore it and go with what the Constitution really says. The problem is that different people will have different views on what the Constitution says, and there needs to be some body to declare what it says, even if they get it wrong. It is simply no rule of law to allow everyone to take the Constitution to say whatever they want it to say. It is far better to have a rule of law, have a Supreme Court who interprets the Consitution in a binding way, and sometimes (or even often) gets it wrong."
Jeremy has set up a false dichotomy. He fails to consider the Jeffersonian alternative:
"My construction of the Constitution is…that each department is truly independent of the others and has an equal right to decide for itself what is the meaning of the Constitution in the cases submitted to its action; and especially where it is to act ultimately and without appeal."
