Cal. Education Code § 76407

(a) Notwithstanding any provision of any law, no community college district, officer of any community college district, college president or superintendent, physician, or hospital treating any minor enrolled in any school in any district shall be held liable for the reasonable treatment of a minor without the consent of a parent or guardian of the child when the minor is ill or injured during regular schools hours, requires reasonable medical treatment, and the parent or guardian cannot be reached, unless the parent or guardian has previously filed with the district a written objection to any medical treatment other than first aid. (b) Notwithstanding any provision of any law, no physician and surgeon who in good faith and without compensation renders voluntary emergency medical assistance to a participant in a community college athletic event or contest at the site thereof, or during transportation to a health care facility, for an injury suffered in the course of the event or contest, shall be liable for any civil damages as a result of any acts or omissions by the physician and surgeon in rendering the emergency medical care. The immunity granted by this paragraph shall not apply in the event of an act or omission constituting gross negligence.
