The Supreme Court said that Justice Ruth Bader Ginsburg is missing arguments for the first time in more than 25 years as she recuperates from cancer surgery last month.

Ginsburg was not on the bench as the court met Monday to hear arguments, and it was unclear when she would return to the court, which will hear more cases on Tuesday and Wednesday, or again next week.

Court spokeswoman Kathy Arberg said the 85-year-old justice is continuing to recuperate and work from home after doctors removed two cancerous growths from her left lung on Dec. 21. Ginsburg was discharged from a New York hospital on Dec. 25.
