Tennessee Code Title 29. Remedies and Special Proceedings § 29-34-305

(a) The plaintiff in any civil action, alleging a silica claim or a mixed dust disease claim, shall file, within one hundred and twenty (120) days after filing the complaint, a written report by a competent medical authority, and any supporting evidence, making out the applicable prima facie case described in § 29-34-304. Any defendant shall have one hundred and twenty (120) days from the filing of the plaintiff's proffered prima facie evidence to challenge the adequacy of the proffered prima facie evidence for failure to comply with the minimum applicable requirements specified in § 29-34-304.

(b) If the court finds that no genuine issue of material fact exists with respect to plaintiff's failure to make out a prima facie case as described in § 29-34-304, the court shall dismiss the plaintiff's claim without prejudice as a matter of law. The court shall maintain its jurisdiction over any case that is so dismissed without prejudice. Any plaintiff whose case has been so dismissed without prejudice may move at any time to reinstate the plaintiff's case, upon a renewed prima facie showing that meets the applicable minimum requirements specified in § 29-34-304.
