In a historic moment on June 26, the US Supreme Court ruled that same-sex marriage is a legal right across all 50 states. The Supreme Court justices ruled states cannot deny gay men and women the same marriage rights. The decision means the 13 states with bans on same-sex marriage are no longer able to enforce them.

    Same-sex couples “ask for equal dignity in the eyes of the law”. Justice Anthony Kennedy wrote in the majority opinion: “The Constitution grants them that right.”

    The decision came after decades of litigation（诉讼） and activism. It set off celebrations across the US. In affected states including Georgia, Michigan, Ohio and Texas, same-sex couples rushed to wed, while officials in Mississippi and Louisiana said marriages had to wait until procedural issues were addressed, reported the BBC.

    According to “The New York Times”, the ruling came against the backdrop of fast-moving changes in public opinion in the US, with polls indicating that most Americans now approve of same-sex marriage.

    US President Barack Obama welcomed the ruling, saying it “affirms what millions of Americans already believe in their hearts.” “Today,” he said in a press release, “we can say, in no uncertain terms, that we have made our union a little more perfect.”

Another win.

    This was the second time the Supreme Court took up same-sex marriage, according to an article in “Business Insider”. The first time, in June 2013, the court made a decision that allowed the US federal government to recognize same-sex marriages in states where they were already legal.

    But at that time, the Supreme Court declined to rule on the broader question about gay marriage: Is there a constitutional（宪法的） right to same-sex marriage? The June 26 ruling gave a positive answer to that question.

Justice Kennedy wrote in the majority opinion that the Constitution should evolve with societal changes.

    “The nature of injustice is that we may not always see it in our own times,” he wrote. “The generations that wrote and ratified the “Bill of Rights” and the “Fourteenth Amendment（修正案）” did not exactly know the extent of freedom in all of its dimensions, and so they hoped the future generations can protect the right of all persons to enjoy liberty as we learn its meaning.”

    The Fourteenth Amendment addresses citizenship rights and equal protection of the law. In the June 26 ruling, the Supreme Court declared that the equal protection clause of the amendment requires marriage rights be extended to same-sex couples, too.
