The US Supreme Court started hearing Tuesday a petition that could lead to legalising same-sex marriage in the entire country. Or leave the law untouched, as it is now.
Either way, it promises to be a historic case with the country tuned in. People started queueing up outside the
court days ago to be able to get a seat in the galleries.
Nine states and the District of Columbia (Washington DC) allow same-sex marriage. California is not among them - and the case before the court comes from that state.
California voted in 2008 to disallow gay and lesbians from marrying in that state. The vote - called Proposition 8 - was struck down by higher courts.
And now it's with the Supreme Court. Supporters of same-sex marriage argue it's guaranteed equal protection by the constitution. Opponents say the constitution is quiet on this issue. And the court should not interfere.
