I'd argue that Citizens United is a great example of that in action. In my opinion, the Court got the law absolutely right in that case. But they used up a lot of trust capital in the process.
The only time the executive has ignored supreme court ruling I believe was when Lincoln was in charge, and well, to say the nation was divided at that time would be an understatement.
This is a really bad idea, you're basically describing an oligarchy. The Supreme Court is really a consensus-enforcing machine, for the most part.
Also, if the equal protection clause was misinterpreted by the judicial branch, the legislative bodies of the federal and state governments have the power to revise and make it clear that the law was never to be interpreted that way.
