Washington ? Supreme Court Justice Ruth Bader Ginsburg, who had cancer surgery earlier this year, was kept at a hospital overnight after she became drowsy and fell from her seat aboard an airplane. Court officials blamed a reaction to medicine.

It was the second time Ginsburg, 76, has been hospitalized in the last month. She was taken to a hospital on Sept. 24 after falling ill at her Supreme Court office.

Ginsburg was taken to Washington Hospital Center around 11:15 p.m. Wednesday by paramedics and released Thursday morning, court officials said.

Ginsburg, along with Chief Justice John Roberts and justices Stephen Breyer and Antonin Scalia, was heading to London to take part in ceremonies marking the opening of Britain’s new Supreme Court.
