LOUISVILLE, Ky. — A federal judge has ruled that Kentucky must recognize same-sex marriages performed in other states, striking down part of the state ban.

In 23-page a ruling issued Wednesday, U.S. District Judge John G. Heyburn II concluded that Kentucky’s laws treat gay and lesbians differently in a “way that demeans them.” The constitutional ban on same-sex marriage was approved by voters in 2004. The out-of-state clause was part of it.
