US court could deliver boost to gay marriage
The court wrapped up its arguments over gay marriage in the US, and Justice Anthony Kennedy joined the four more liberal justices in raising questions about the provision of the federal Defence of Marriage Act that is being challenged at the Supreme Court.
Justice Kennedy said the law appears to intrude on the power of states that have chosen to recognise same-sex marriages.
Other justices said the law creates two classes of marriage.
The federal law affects a range of benefits available to married couples, including tax breaks, survivor benefits and health insurance for spouses of federal employees.
