SAN FRANCISCO — The First District Court of Appeal has been encouraging attorneys to file electronic briefs along with paper versions for some time. But starting March 17, e-filing will become mandatory for virtually all civil cases. Attorneys will be required to file in PDF or compatible format and submit through ImageSoft’s TrueFiling system. E-filing will be required for criminal cases as of April 14.

Few appellate lawyers know the system better than Gordon & Rees partner Don Willenburg, the only practicing lawyer on the Judicial Council’s Court Technology Advisory Committee. Led by First District Justice Terence Bruiniers, the committee has been hammering out the project in earnest over the last year, and Willenburg and a few colleagues in the appellate bar have spent the last several weeks giving it a test-drive.
