The US Supreme Court has decided not to revisit its ruling a decade ago legalising same-sex marriage.

The justices turned down an appeal from Kim Davis, who was ordered by a lower court to pay compensation to a same-sex couple after refusing to grant them a marriage licence.

Ms Davis argued that same-sex marriage conflicted with her beliefs as an Apostolic Christian.

The 2015 ruling in the case of Obergefell v Hodges was a historic victory for LGBT rights in the US, but some conservatives argue it dealt a blow to religious liberty.

Davis appealed in a civil rights lawsuit by David Ermold and David Moore, a couple who accused her of violating their constitutional right to marry.
