Justice Sonia Sotomayor ’76–who has already been confirmed and sworn in–was made even more Justice-y yesterday at her investiture, when she was officially seated on the bench.

Everyone was there–Obama, Biden, and even Ricky Martin!

Sotomayor hears her first oral arguments today in the case Citizens United v. Federal Election Commission. Representing the federal government, which is defending campaign finance laws, will be Solicitor General Elena Kagan ’81, who is also making her Supreme Court debut.

And that crazy collar Sotomayor is wearing with her robe? It’s called a jabot (pronounced “zha-BO,” according to the NYT), and it’s clearly a socialist collar because it was made in Canada and was a present from Justice Ruth Bader Ginsburg.
