How have counsel reviewed the record in a personal injury case?

Defendant's appointed counsel found no arguable issues and filed a brief under People v. Wende (1979) 25 Cal.3d 436 (Wende), asking this court to independently review the record. On April 23, 2020, we directed counsel to send the record and a copy of the opening brief to appellant. Both his counsel and this court informed defendant that counsel had been unable to find any arguable issues. Defendant was invited to submit a supplemental brief or letter within 30 days raising any contentions he wished this court to consider. He did not do so.
