So, you just think they asked the wrong question?
Please, take the tin foil hat off.
Roberts said, We are not going to save you from your stupid political mistakes, you figure that out.
We get the government we deserve, collectively!
If the Court missed the fact that this “tax” did not properly originate in the House, it is going to have to address this in another opinion to maintain any credibility as constitutional arbiter.
And you don't understand that without a pleading by one of the parties before the court, the court has no jurisdiction to rule as though the pleading had in fact been made.
The legal argument I have presented was not one of the pleadings made by any of the parties. That's why the Court did not consider it officially, nor they discuss it in their opinion. It was not a matter before the court.
