Chief Justice John Roberts Jr. on Thursday urged federal judges and lawyers to redouble their efforts to make civil litigation more just and efficient, admonishing them to change the legal culture and narrow the scope of discovery.

Roberts’ annual report on the federal judiciary focused entirely on the “just, speedy and efficient resolution of civil disputes,” as he highlighted new revisions in the Federal Rules of Civil Procedure that are aimed at achieving those goals. They took effect on Dec. 1.
