HS 11361.5. (a) Records of any court of this state, any public or private agency that provides services upon referral under Section 1000.2 of the Penal Code, or of any state agency pertaining to the arrest or conviction of any person for a violation of subdivision (b), (c), (d), or (e) of Section 11357 or subdivision (b) of Section 11360, shall not be kept beyond two years from the date of the conviction, or from the date of the arrest if there was no conviction, except with respect to a violation of subdivision (e) of Section 11357 the records shall be retained until the offender attains the age of 18 years at which time the records shall be destroyed as provided in this section. Any court or agency having custody of the records shall provide for the timely destruction of the records in accordance with subdivision (c). The requirements of this subdivision do not apply to records of any conviction occurring prior to January 1, 1976, or records of any arrest not followed by a conviction occurring prior to that date.
c) Destruction of records of arrest or conviction pursuant to subdivision (a) or (b) shall be accomplished by permanent obliteration of all entries or notations upon the records pertaining to the arrest or conviction, and the record shall be prepared again so that it appears that the arrest or conviction never occurred. However, where (1) the only entries upon the record pertain to the arrest or conviction and (2) the record can be destroyed without necessarily effecting the destruction of other records, then the document constituting the record shall be physically destroyed.
HS 11361.7. (a) Any record subject to destruction or permanent obliteration pursuant to Section 11361.5, or more than two years of age, or a record of a conviction for an offense specified in subdivision (a) or (b) of Section 11361.5 which became final more than two years previously, shall not be considered to be accurate, relevant, timely, or complete for any purposes by any agency or person. The provisions of this subdivision shall be applicable for purposes of the Privacy Act of 1974 (5 U.S.C. Section 552a) to the fullest extent permissible by law, whenever any information or record subject to destruction or permanent obliteration under Section 11361.5 was obtained by any state agency, local public agency, or any public or private agency that provides services upon referral under Section 1000.2 of the Penal Code, and is thereafter shared with or disseminated to any agency of the federal government. (b) No public agency shall alter, amend, assess, condition, deny, limit, postpone, qualify, revoke, surcharge, or suspend any certificate, franchise, incident, interest, license, opportunity, permit, privilege, right, or title of any person because of an arrest or conviction for an offense specified in subdivision (a) or (b) of Section 11361.5, or because of the facts or events leading to such an arrest or conviction, on or after the date the records of such arrest or conviction are required to be destroyed by subdivision (a) of Section 11361.5, or two years from the date of such conviction or arrest without conviction with respect to arrests and convictions occurring prior to January 1, 1976. As used in this subdivision, "public agency" includes, but is not limited to, any state, county, city and county, city, public or constitutional corporation or entity, district, local or regional political subdivision, or any department, division, bureau, office, board, commission or other agency thereof.
