Bos v. Smith, 556 S.W.3d 293

Background

Father (Craig) had court-ordered visitation (standard possession order) with his two young sons after divorce; Mother (Trisha) repeatedly denied or limited access.
After a brief visit in October 2008, Mother accused Father of sexually abusing their son Mike; DFPS and police investigated, the boys underwent exams, and an extended investigation followed that ultimately found the allegations unfounded.
Mother coached Mike to make false outcries over many months; Mother later relinquished parental rights to avoid jail for contempt after violating the possession order.
Father sued the grandparents (Larry and Mary Bos) — not Mother — for (a) aiding/assisting violations of his possessory rights under Tex. Fam. Code ch. 42, (b) negligence and breach of fiduciary duty to the children, and (c) defamation based on Grandfather’s statements to DFPS; trial court awarded >$10.5M; court of appeals affirmed most claims but reversed on defamation in part.
The Texas Supreme Court affirmed reversal of the defamation awards (insufficient pleadings / causation) and reversed the remaining awards, rendering judgment for the grandparents, holding no legally sufficient evidence of a Chapter 42 violation or proximate causation for the tort claims.

Issues

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether grandparents are liable under Fam. Code §42.003 for "aiding or assisting" Mother's interference with Father’s possessory rights	Grandfather and Grandmother aided Mother’s withholding of visitation (e.g., took boys to party, kept them, failed to tell DFPS material facts) and thus are jointly liable under Ch. 42	Grandparents lacked knowledge of the order’s contents and did not have actual notice or reasonable cause to believe their acts would violate the order; assistance must be tied to a specific interference	Reversed: evidence legally insufficient. Plaintiff failed to prove grandparents knew or reasonably should have known their acts would violate the order; specific violations must be proven separately.
Whether negligence / breach of fiduciary duty by grandparents proximately caused the boys’ injuries	Grandparents had custody/monitoring duties and breached ordinary-care and fiduciary duties, causing harm to the children	Mother’s conduct (coaching and fabrication of abuse) was extraordinary and unforeseeable; thus grandparents’ breach could not be the proximate cause	Reversed: no proximate cause as a matter of law because Mother’s conduct was unforeseeable and thus superseded any duty/breach by grandparents.
Whether Grandfather’s DFPS statements supported twins’ defamation claim	Twins claimed Grandfather defamed them by implying they were abuse victims and subject to brainwashing	Grandfather argued pleadings did not assert a defamation claim on behalf of the twins and thus lacked fair notice	Reversed: judgment for twins invalid — pleadings did not fairly notify Grandfather of that theory and the claim was not tried by consent.
Whether Grandfather’s DFPS statements supported Father’s defamation claim	Father claimed statements that he abused the girls and would brainwash them defamed him and caused his damages	Grandfather argued statements were not a substantial factor in causing Father’s injuries given overwhelming other false accusations by Mother/Bruno and Mother’s conduct was the primary cause	Reversed: no legally sufficient evidence of proximate cause — Grandfather’s statements were not a substantial factor in causing Father’s losses.
