Amendment IX "The enumeration in the Constitution, of certain rights, shall not be construed to deny or disparage others retained by the people."<quoted text>
I did not ask what the courts said - I asked if in the constitution itself, there was explicit mention of marriage as a right. Appellate decisions can be overturned - such as Roe v. Wade (hopefully soon).
The fact marriage has existed in many different forms including same sex couples, around the world and throughout history, would be enough to establish marriage as a fundamental right, even if the Supreme Court on 14 occasions, as well as numerous appellate and trial courts, had not also recognized marriage as a fundamental right of all people, protected by the constitution.
