"The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people."
The 10th Amendment did not give the Supreme Court the authority to decide what is and what is not Constitutional. In 1803 the Supreme Court decided that it had the power take from the states and the people their right to determine which laws were Constitutional and which ones were not.
Since this power was not specifically delegated by the states to the Supreme Court it is a power reserved to the states and the people.
The men who wrote the Constitution delegated a short list of enumerated powers to the government od the United States and reserved all other powers not mentioned to the states and to the people.
When the court assumed hte power of Judicial Review in 1803 they stole the from the states and the people their right to determine which laws were Constitutional annd which ones were not.
In the process they turned the weakest of the three branches of government into the most powerful one. The opinions on a panel of unelected, unaccountable, partisan politicians became more powerful than Congress and the President.
The President can veto Congressional legislation and Congres can over ride the Presidents veto, but who can overturn the opinions made by the Supreme Court?.
The President has the responsibility to veto all bills that he beleives violate the Constitution and Congress has the power to over ride his veto.
The primary function of the Supreme Court should be to settle disputes between the sates not to over rule the will of the Congressional representatives of the people.
