Good idea, but no matter how they amend the constitution, the courts are going to make up whatever they want it to say anyway.
That's another idea for an amendment. Eliminate life tenure for federal judges, including SCOTUS. Make the terms of office for 15 or 20 years, and they cannot be reappointed to the same level of the court. So they could serve one term at the district court level, one term at the court of appeals (if they were appointed), and one term at SCOTUS, if appointed. That would be it.
And at the same time, prohibit the federal courts from creating laws by imposing their own solutions on us. If the court overturns a law or a part of a law, it must go back to Congress if it is to be changed - otherwise the law ceases to exist. The court cannot change the law to make it work (by calling a fine a tax, for example).
So your solution is to do nothing?
