In a landmark ruling, the U.S. Supreme Court ruled today that the Constitution guarantees a right to same-sex marriage.

Before this ruling, same-sex marriage was recognized in 37 states. The case before the Supreme Court included two Michigan nurses who petitioned that Michigan's ban was a violation of their rights.

In the ruling, Justice Kennedy cited the challenge brought by DeBoer and Rowse, a couple with four adopted children between them who claimed Michigan's 2004 same-sex marriage ban was a violation of their due process and equal protection rights under the U.S. Constitution.

The University of Michigan has legal experts who can offer reaction to the decision.

"Today's decision marks a bigger change in American law than anything since Brown v. Board of Education," he said. "And like Brown, which was controversial when decided, today's decision may soon come to be seen as no more than simply justice and common sense."Contact: 734-647-5543, [email protected]

Julian Davis Mortenson, professor of law, has years of LGBT rights litigation experience both as a constitutional law specialist and as a scholar. He was lead counsel in a federal case (Caspar v. Snyder) that won recognition for 300 same-sex couples in Michigan in January 2015.

"This is a historic ruling that makes marriage equality the law in all 50 states. It is a sweeping and utterly unambiguous win for LGBT rights. It settles the issue so straightforwardly that there is little uncertainty about its implementation," he said. "It is also grounded on a secure foundation of precedent. It's at least the third time that the Supreme Court has relied on due process and equal protection principles to strike down the exclusion of LGBT persons from basic rights of citizenship."Contact: 315-657-1055, [email protected]
