Justice Ginsburg returns to court after battling lung cancer

U.S. Supreme Court Justice Ruth Bader Ginsburg is back at the court after missing oral arguments in January as she recovered from lung cancer surgery at home, a court official said on Friday.

Ginsburg, who will turn 86 in March, had been working from home and participating and voting in cases since her December surgery by reading argument transcripts and case briefs. She attended the justices' closed-door conference to discuss cases on Friday.
