In In re J.F.C., 57 S.W.3d 66, 72 (Tex. App.-Waco 2001), the court of appeals held that Fourteenth Amendment procedural due process concerns require review of "core issues" in the jury charge in involuntary termination cases even when the parties failed to object to the charge at the trial court. 57 S.W.3d at 72. Without addressing whether appellate courts could review the unpreserved charge error, this Court reversed the court of appeals' judgment in J.F.C. because we concluded that the evidence conclusively established one of the grounds for termination, making the alleged charge error harmless. 96 S.W.3d at 277-79.
