The New York Times had a great article on the ruling. Here's an excerpt:

WASHINGTON — In a long-sought victory for the gay rights movement, the Supreme Court ruled on Friday that the Constitution guarantees a right to same-sex marriage.

Justice Anthony M. Kennedy wrote the majority opinion in the 5 to 4 decision. He was joined by the court's four more liberal justices.

The decision, the culmination of decades of litigation and activism, came against the backdrop of fast-moving changes in public opinion, with polls indicating that most Americans now approve of same-sex marriage.

Justice Kennedy said gay and lesbian couples had a fundamental right to marry.

"No union is more profound than marriage, for it embodies the highest ideals of love, fidelity, devotion, sacrifice, and family," he wrote. "In forming a marital union, two people become something greater than once they were."

Some of you may be surprised to know that many Christians will rejoice in this decision. Not all Christians think the same. Justice Anthony Kennedy, who wrote the Supreme Court decision, is an active Catholic who enjoys a good reputation here in his home diocese of Sacramento.

The denial of the right to marriage was an offense against Christian charity.
