"Section 2. The judicial Power shall extend to all Cases, in Law and Equity, arising under this Constitution."
All cases arising under the Constitution.
I think the people had a right to sue, of course. But the judge should not have intruded himself into deciding curriculum. Nothing now prohibits another judge from deciding curriculum.
My opinion differs from the judge, and the judge unfortunately decided to stick his nose into the decision of local school boards.
I think that is an abuse of judicial power. He has no Constitutional right to do that, in my opinion. The determinative factor is that the Constitution does not give such powers to them.
The Constitution does not give powers of curriculum choices to the federal government. The Constitution specifically PROHIBITS the powers of the feds.
If you want to use "all cases...arising under this Constitution" down to local districts, you're shredding the 10th Amendment.
