What is the legal test used to determine whether a plaintiff has been successful on an appeal?

In accordance with the procedures described in People v. Cole (2020) 52 Cal.App.5th 1023, 1038, review granted Oct. 14, 2020, S264278, we appointed counsel to represent Sanders on appeal. After reviewing the record, counsel filed a brief raising no issues. On October 21, 2020 we notified Sanders he had 30 days to submit a brief or letter raising any grounds of appeal, contentions, or arguments he wanted the court to consider. On January 7, 2021 we received a 75-page supplemental brief, including exhibits, in which Sanders argued he had made a prima facie showing of eligibility for relief, noting the jury instruction on conspiracy referred to the natural and probable consequences doctrine.⁵
