When a lawyer files a lawsuit on behalf of a client, he is not exercising his own right to petition, and a later legal malpractice claim related to that underlying lawsuit is not subject to dismissal under the Tennessee Public Protection Act.
In Cartwright v. Hendrix, No. W2022-01627-SC-R11-CV (Tenn. Dec. 9, 2025), the Tennessee Supreme Court considered the issue of whether a lawyer sued for legal malpractice could invoke the TPPA to seek dismissal of the case. The defendants in this case represented the plaintiff in multiple lawsuits related to the administration of a trust. After over ten years of unsuccessful litigation, the plaintiff filed this legal malpractice case against the defendants.
The defendant lawyers filed a petition to dismiss under the Tennessee Public Protection Act (“TPPA”). The defendants argued that the claims related to their right to petition and were thus covered by the TPPA. The trial court found that the TPPA did not apply, but the Court of Appeals reversed that holding. In this opinion, the Tennessee Supreme Court ruled that the TPPA did not apply because the lawyers were not exercising their own right to petition.
