On June 26, 2015, the United States Supreme Court, in a 5-4 ruling in the case of Obergefell v. Hodges, illegally claimed that same-sex "marriage" was "legal" in all 50 states, despite not having the power or authority to make such a ruling.
Uh…how in the hell does the Supreme Court not have the power and authority to rule that laws are unconstitutional? That’s one of their reasons for existing. In the words of Chief Justice John Marshall, from Marbury v Madison, 1803, “It is emphatically the province and duty of the judicial department to say what the law is. Those who apply the rule to particular cases, must of necessity expound and interpret that rule. If two laws conflict with each other, the courts must decide on the operation of each.” AKA judicial review. Now, you can certainly disagree with their decisions all you want, I don’t think they got them right every time myself, but I won’t dispute that those decisions were law. (until they got ruled to be otherwise)
