WASHINGTON (AP) -- The Supreme Court declared Friday that same-sex couples have a right to marry anywhere in the United States.

Gay and lesbian couples already could marry in 36 states and the District of Columbia. The court's 5-4 ruling means the remaining 14 states, in the South and Midwest, will have to stop enforcing their bans on same-sex marriage.

The outcome is the culmination of two decades of Supreme Court litigation over marriage, and gay rights generally.

Justice Anthony Kennedy wrote the majority opinion, just as he did in the court's previous three major gay rights cases dating back to 1996. It came on the anniversary of two of those earlier decisions.
