Some excerpts from Justice Alito’s 8-page dissent (joined by Scalia and Thomas):
The question in these cases … is not what States should do about same-sex marriage but whether the Constitution answers that question for them. It does not. The Constitution leaves that question to be decided by the people of each State.
For today’s majority, it does not matter that the right to same-sex marriage lacks deep roots or even that it is contrary to long-established tradition. The Justices in the majority claim the authority to confer constitutional protection upon that right simply because they believe that it is fundamental.…
While, for many, the attributes of marriage in 21st-century America have changed, those States that do not want to recognize same-sex marriage have not yet given up on the traditional understanding. They worry that by officially abandoning the older understanding, they may contribute to marriage’s further decay. It is far beyond the outer reaches of this Court’s authority to say that a State may not adhere to the understanding of marriage that has long prevailed, not just in this country and others with similar cultural roots, but also in a great variety of countries and cultures all around the globe.
Today’s decision usurps the constitutional right of the people to decide whether to keep or alter the traditional understanding of marriage. The decision will also have other important consequences.
It will be used to vilify Americans who are unwilling to assent to the new orthodoxy. In the course of its opinion, the majority compares traditional marriage laws to laws that denied equal treatment for African-Americans and women. The implications of this analogy will be exploited by those who are determined to stamp out every vestige of dissent.
Perhaps recognizing how its reasoning may be used, the majority attempts, toward the end of its opinion, to reassure those who oppose same-sex marriage that their rights of conscience will be protected. We will soon see whether this proves to be true. I assume that those who cling to old beliefs will be able to whisper their thoughts in the recesses of their homes, but if they repeat those views in public, they will risk being labeled as bigots and treated as such by governments, employers, and schools.…
Today’s decision will also have a fundamental effect on this Court and its ability to uphold the rule of law. If a bare majority of Justices can invent a new right and impose that right on the rest of the country, the only real limit on what future majorities will be able to do is their own sense of what those with political power and cultural influence are willing to tolerate. Even enthusiastic supporters of same-sex marriage should worry about the scope of the power that today’s majority claims.
Today’s decision shows that decades of attempts to restrain this Court’s abuse of its authority have failed. A lesson that some will take from today’s decision is that preaching about the proper method of interpreting the Constitution or the virtues of judicial self-restraint and humility cannot compete with the temptation to achieve what is viewed as a noble end by any practicable means. I do not doubt that my colleagues in the majority sincerely see in the Constitution a vision of liberty that happens to coincide with their own. But this sincerity is cause for concern, not comfort. What it evidences is the deep and perhaps irremediable corruption of our legal culture’s conception of constitutional interpretation.
