Parker appealed from the order denying his petition for a certificate of rehabilitation and pardon under Penal Code section 4852.01 et seq. He contended that California’s five-year residency requirement violated his constitutional right to travel by providing for disparate treatment for resident and nonresident ex-felons. The appellate court rejected the argument, finding that California has a legitimate and substantial interest in requiring sufficient residency to determine whether a petitioner’s conduct warrants a certificate stating that he is rehabilitated.
