That depends on the basis for the disagreement.
Plus, I don't see an impeachment farce as any worse than a constitutional farce, where, e.g., every federal law is withing the limited powers granted by the constitution because everything has some relation to commerce.
If a judge make a pronouncement of law based on pure fiction (e.g., "Miller was convicted, we upheld the law"), that's a farce too. If all three branches o along with it, the people don't have a remedy in the constitution.
I appreciate that Congress does not want to impeach, because then IT would be accountable. Plus, as I noted above, Congress LIKES for the Courts to give force to unconstitutional Congressional enactments. They like being empowered, even if the empowerment is illegitimate under the constitution.
Congress also likes the Court’s power because politicians can grandstand on passing laws that they know are unconstitutional, and then blame the Court when they are overturned.
