Cal. Bus. & Prof. Code § 23001.5

If any provision of this division or the application thereof to any person or circumstances is held invalid, such invalidity shall not affect other provisions or applications of this division that can be given effect without the invalid portion or application, and to this end the provisions of this division are severable. It is the intent of the Legislature that this division would have been adopted regardless if such invalid provision had not been included or any invalid application had not been made.
