It would save a lot of time if you'd get around to demonstrating a flaw in my understanding, or actually offering the explanation and clarification I'm requesting.
I have clearly explained why I think SCOTUS is constitutionally empowered to rule on constitutional issues. Show me the flaw in my comprehension.
No. I read it. I found no examples mentioned that contradicted the viewpoint I have presented.
For example:
That is perfectly consistent with my viewpoint, and contradicts the other person's argument that the court oversteps its bounds.
The court's function is to resolve "cases". Where two parties come to a disagreement, the court is, indeed, the final arbiter of that disagreement. Where that disagreement is related to constitutionality, the court is requested and required to provide a ruling. That is their job.
Again, not a problem, until there is a conflict between the executive branch and someone else: where a case arises between the executive branch and another party, the court is specifically empowered to resolve that case. Until such a conflict arises, the executive branch is, indeed, empowered to interpret the constitution. But, once that "case" has arisen, Article III puts the ball in the courts.
That very ruling is an example of the court interpreting the constitution at the behest of the parties to a "case". The court would have no ability to respond to address that issue without the parties disagreeing on who was constitutionally empowered to determine what was "proper". If everyone has agreed that the Senate was charged with that duty, the courts don't get involved in the interpretation. If everyone agreed the president, or a magic eight ball was charged with that duty, the courts don't get involved because no case has arisen.
On and on, the essay repeatedly tried to show that there was some inherent problem with the judicial branch doing exactly what Article III empowered it to do: to hear cases. The essay doesn't seem to support the other person's initial claims about the court taking powers it wasn't assigned. But, despite repeated queries, I could get no further context for their claim other than an essay that doesnt support such a claim.
I still can't get you to challenge my own understanding, other than to point at the same essay that doesn't seem to support your position, nor can I get any information from you about what your position actually is.
Address some part of your claims that Article III doesn't mean what it says on the tin. Show me what you are talking about and how it differs from my own understanding.
