US justices consider gay marriage
26 March 2013 Last updated at 06:51 GMT
The US Supreme Court is to consider two landmark cases on gay marriage in back-to-back-hearings.
On Tuesday, the justices will weigh a California constitutional amendment banning same-sex unions, passed after gay marriage became legal there. On Wednesday, a federal law defining marriage as between a man and a woman only, for the purpose of taxes and benefits, is up for review.
The court is expected to hand down its ruling by the end of June.
