California Code, Business and Professions Code - BPC § 6085.5

(a) Admission of culpability.

(b) Denial of culpability.

(c) Nolo contendere, subject to the approval of the State Bar Court.  The court shall ascertain whether the licensee completely understands that a plea of nolo contendere shall be considered the same as an admission of culpability and that, upon a plea of nolo contendere, the court shall find the licensee culpable.  The legal effect of such a plea shall be the same as that of an admission of culpability for all purposes, except that the plea and any admissions required by the court during any inquiry it makes as to the voluntariness of, or the factual basis for, the pleas, may not be used against the licensee as an admission in any civil suit based upon or growing out of the act upon which the disciplinary proceeding is based.
