Can appointed counsel file an opening brief in a personal injury case?

Appointed counsel filed an opening brief that sets forth the facts of the case and requests this court to review the record and determine whether there are any arguable issues on appeal. (People v. Wende, supra, 25 Cal.3d 436.) Defendant was advised by counsel of the right to file a supplemental brief within 30 days of the date of filing of the opening brief. Defendant's supplemental brief was untimely, but we granted him permission to file the brief.
