US: Only one state has an unchallenged ban on same-sex marriage
There is now only one state in the US with a ban on same-sex marriage which is not being challenged in court.
But North Dakota, in which voters approved a ban on same-sex couples marrying back in 2004, remains the only state without a challenge to its ban.
There are now over 30 US states with legal challenges against same-sex marriage bans. Another 19, and the District of Columbia allow same-sex couples to marry.
Dozens of gay and lesbian couples in the US state of Pennsylvania rushed last week to obtain marriage licences, as a judge struck down its same-sex marriage ban, and the state said it would no longer defend it.
Voters in North Dakota approved a ban on same-sex marriage back in 2004, with 73%.
