WASHINGTON – Supreme Court Justice Ruth Bader Ginsburg was hospitalized Tuesday for "a benign gallbladder condition" that caused an infection, a Supreme Court spokeswoman announced.

Ginsburg, 87, underwent "non-surgical treatment" for acute cholecystitis, and is expected to remain at Johns Hopkins Hospital for a day or two.

The spokeswoman said Ginsburg plans to participate in the telephone arguments on Wednesday, just as she did Monday and Tuesday.

Ginsburg initially sought medical care Monday after oral arguments and received outpatient tests at Sibley Memorial Hospital, which confirmed that she had a gallstone blocking her cystic duct that resulted in an infection.
