A court hearing on Tuesday in Chicago at which former Northwestern University journalism students planned to fight a subpoena for their records and grades turned into a judicial lambasting of their Sidley Austin lawyers.

It started when Judge Diane Gordon Cannon of the Cook County Circuit Court called the lawyers, partner Richard O’Brien and associate Linda Friedlieb, to the bench before prosecutors from the Cook County State’s Attorney’s Office had even arrived. She asked who had written the brief she was holding. O’Brien and Friedlieb responded that they had submitted the reply supporting the motion to quash the subpoena.
