The court announced Friday that it also will decide whether Congress can deprive legally married gay couples of federal benefits otherwise available to married people. A provision of the federal Defense of Marriage Act limits a range of health and pension benefits, as well as favorable tax treatment, to heterosexual couples.
The cases probably will be argued in March, with decisions expected by late June.
The group Freedom to Marry Ohio has until July 3 to gather nearly 400,000 valid signatures to put the amendement on the Ohio ballot. The last time a gay marriage amendment was on the ballot in Ohio was in 2004. That issue made it unconstitutional to recognize same-sex marriages and passed with more than 60 percent of the vote.
