If any provision or clause of this code or application thereof to any person or circumstances is held invalid, such invalidity shall not affect other provisions or applications of the code which can be given effect without the invalid provision or application, and to this end the provisions of this code are declared to be severable.
Unless the provision or context otherwise requires, these preliminary provisions and rules of construction shall govern the construction of this code.
Division, chapter, article, and section headings do not in any manner affect the scope, meaning, or intent of the provisions of this code.
