The Supreme Court took no action on any of the 10 gay-marriage petitions before it Friday, despite expectations that the justices would finally announce their plans regarding challenges to three separate laws denying recognition to same-sex couples.

The court could add any of those cases to its docket as soon as Monday, but more likely the justices will continue discussing the matter at their next private conference, scheduled for Dec. 7.

Most attention has focused on challenges to the federal Defense of Marriage Act, a 1996 statute denying federal benefits to lawfully married same-sex spouses. Federal appeals courts in Boston and New York have found the measure unconstitutional, finding that the government had insufficient justification to penalize gays and lesbians.
