Google Inc. filed a motion under seal Tuesday to address matters that previously caused a judge to abruptly adjourn an administrative hearing between the company and the U.S. Department of Labor over its alleged failure to turn over data on its hiring practices.

Google filed its sealed motion April 18 at the instruction of Administrative Law Judge Steven Berlin, who is presiding over the hearing in the Office of Administrative Law Judges in San Francisco.

Attorneys said that it was an unusual move for the venue, and it could have been done to protect confidential or privileged information or data belonging to Google.
