(b) Subsection (a) shall not preclude civil liability where the claim of weight gain, obesity, health condition associated with weight gain or obesity, or other generally known condition allegedly caused by or allegedly likely to result from long term consumption of food is based on:

(1) A material violation of an adulteration or misbranding requirement prescribed by statute or regulation of the state of Tennessee or the United States of America and the claimed injury was proximately caused by such violation; or

(2) Any other material violation of federal or state law applicable to the manufacturing, marketing, distribution, advertising, labeling, or sale of food; provided, that such violation is knowing and willful, and the claimed injury was proximately caused by such violation.

(c) For purposes of this section:

(1) “Claim” means any claim by or on behalf of a natural person, as well as any derivative or other claim arising therefrom asserted by or on behalf of any other person;

(2) “Generally known condition allegedly caused by or allegedly likely to result from long term consumption” means a condition generally known to result or to likely result from the cumulative effect of consumption, and not from a single instance of consumption;

(3) “Knowing and willful” violation of federal or state law means that:

(A) The conduct constituting the violation was committed with the intent to deceive or injure consumers or with actual knowledge that such conduct was injurious to consumers; and

(B) The conduct constituting the violation was not required by regulations, orders, rules or other pronouncement of, or any statute administered by a federal, state, or local government agency;

(4) “Other person” as used in subdivision (c)(1) means any individual, corporation, company, association, firm, partnership, society, joint stock company, or any other entity, including any governmental entity or private attorney general.

(d)

For purposes of this section, the pleading requirements in this subsection (d) are hereby deemed part of the substantive law of the state of Tennessee and not merely in the nature of procedural provisions.

(e) In any action exempted under subsection (a), all discovery and other proceedings shall be stayed during the pendency of any motion to dismiss, unless the court finds upon the motion of any party that particularized discovery is necessary to preserve evidence or to prevent undue prejudice to that party. During the pendency of any stay of discovery pursuant to this subsection (e), unless otherwise ordered by the court, any party to the action with actual notice of the allegations contained in the complaint shall treat all documents, data compilations, including electronically recorded or stored data, and tangible objects that are in the custody or control of such party and that are relevant to the allegations, as if they were the subject of a continuing request for production of documents from an opposing party under the state of Tennessee rules of civil procedure.
