From the U.S. Constitution – Article I, Section 1.
“All legislative powers herein granted shall be vested in a Congress of the United States, which shall consist of a Senate and House of Representatives.”
The above clearly means that Congress is the only part of the government that can make new laws or change existing laws, NOT the Supreme Court. So, does it not make sense that the Supreme Court can only ISSUE opinion? Yes. And opinions are not laws. Only A statement of the Court’s thoughts on a considered subject. Not law.
From the U.S. Constitution – Article VI, clause 2
1. The supremacy clause of the federal Constitution (Art. VI, clause 2) “This Constitution, and the laws of the United States which shall be made in pursuance thereof; and all treaties made, or which shall be made, under the authority of the United States, shall be the supreme law of the land; and the judges in every state shall be bound thereby, anything in the Constitution or laws of any State to the contrary notwithstanding.” Supreme Court “opinions” are NOT part of that supreme law.
