Same-Sex Marriage: Who Should Decide?

The first time same-sex marriage was officially recognized was in Holland in 2001. Now, it's permitted in 36 American states and the District of Columbia. Today, the US Supreme Court was asked to overturn bans on the practice in Kentucky, Michigan, Ohio and Tennessee — essentially legalizing it for the entire country. History and the speed of change were on the minds of justices including Anthony Kennedy, who observed, "I don't even know how to count the decimals when we talk about millennia. This definition has been with us for millennia, and it's very difficult for the court to say, 'oh well, we know better'."

Can nine justices rule that gays and lesbians should be able to marry — or is that a right granted to individuals by the Constitution? Should the US Supreme Court let the democratic process continue state by state? These were some of the questions raised today in a case asking the Court to overturn gay-marriage bans in Kentucky, Michigan, Ohio and Tennessee. We hear about some arguments rooted in ancient history and others based on the recent sea-change in public opinion.
