He did his job..you just don’t agree with his conclusion.
There is a reason for 9 Justices. There are usually at least nine opinions.
The framers, knowing there are always going to be different legal interpretations to any legal question, created the SC.
That said the SC is not infallible, but it usually takes 3 or 4 generations at least to reverse a decision. The minority view can become the majority but in the mean time our system is set up to enforce the view of the majority on the SC....
Four of those justices are just there to rubber stamp what ever the Democrat Party wants them to. You can all guess who they are. They could care less what the Constitution says on anything. It means nothing to them. No the framers did not know what John Marshall had in store for them. They found out the hard way in Marbury v Madison. Most of them were horrified, by the way the loser of that case was the guy who is called the father of the constitution.
