Almost two-thirds of same-sex marriage licences in a Minnesota county bordering North Dakota, were issued to same-sex couples with at least one resident of the North Dakota.

According to reports, Clay County Deputy Recorder Lisa Junze said forty out of 68 same-sex marriage licences filed were for couples both from North Dakota, and another five were for couples where at least one of them were from the state.

Same-sex couples have been able to marry in Minnesota since August 2013, however North Dakota remains the only state in the US with a same-sex marriage ban which is not being challenged in court. 

South Dakota became the latest state with a legal challenge to a ban on same-sex marriage, as six couples filed a lawsuit there at the end of last week.

There soon may change, as according to reports, a lawsuit will soon be filed in the state of North Dakota to challenge its ban on same-sex marriage.

Voters in North Dakota approved a ban on same-sex marriage back in 2004, with 73%.
