Well, that's the entire question.
There are two basic schools of thought.
The first view is that
constitutionally-enforceable fundamental rights are either those that existed and were recognized at the time the Constitution was ratified, or that were added subsequently as Amendments. The 14th Amendment is broad enough that any general rights that were considered fundamental
at that time generally are incorporated as well. The recognition of those rights and our decision to make them legally enforceable was accomplished through the Constitutionally-specific means of ratification.
Under that view, if you want to recognize a new "fundamental right" that can be enforced by courts, then the proper thing to do is to follow the procedure that made the original ones constitutionally protected --
pass a constitutional amendment. That's why the Amendment process was created.
The other view, which is the one that led to the decision today, is that the
Supreme Court (not Congress and the states through the Amendment process) should recognize new, legally-enforceable "fundamental rights" whenever it sees the need. Justice Kennedy described that (and his) viewpoint in this very opinion:
In all of those decisions, Justice Kennedy embraced a vision of a living Constitution, one that evolves with societal changes.
“The nature of injustice is that we may not always see it in our own times,” he wrote on Friday. “The generations that wrote and ratified the Bill of Rights and the Fourteenth Amendment did not presume to know the extent of freedom in all of its dimensions, and so they entrusted to future generations a charter protecting the right of all persons to enjoy liberty as we learn its meaning.”

Now, that sounds absolutely wonderful, doesn't it? I mean, what right-thinking person thinks that the Constitution should be frozen in time?
But the bolded language is just incredibly
self-centered bullshit on his part in this context. What that Charter does is give to those "future generations"
the ability to pass Amendments to add to the Constitution as we see fit. That's what the people who enacted the Bill of Rights and the Fourteenth Amendment (and all the others) did, right? They saw a need to change the Constitution to adapt to new times, and so altered the Constitution
through the Constitutionally-described process for Amendments. The ability to change the Constitution
through Amendments is what was "entrusted to future generations."
But that's not what Kennedy is advocating at all. When Kennedy is talking about "future generations" changing the meaning he's talking not about
we the people as a whole making those changes through our Constitution, but rather about those nine Justices deciding on their
own when it is time for a new right to be created. Even if a majority of citizens don't agree. Now, that's all fine and dandy if you like the result. But what if you don't?
I'd point out that what Kennedy advocates here has no logical or justiciable limit. What rights should be recognized as "fundamental" are based solely on what those particular justices think should be fundamental. And what's so bogus is that is ultimately a
moral question, not a legal one. And we're supposedly picking those justices because of their legal insight, not because they're
morally superior to the rest of us.
There is no restriction, at all, one what new rights the Court can choose to recognize as fundamental. For example, you can run down some of the "human rights" declarations floating around and find all sorts of things that some consider to be "fundamental human rights". The "Universal Declaration of Human Rights" includes, in Articles 22-26, all sorts of "economic" rights that we've never recognized here. And if some future group of 5 Justices decided to alter fundamentally our economic system hby adopting all those things as "fundamental rights", they could rightly point to Kennedy's opinion in this case as recognizing that it is right for them to do so.
