COA08 — January 29, 2026
In this medical liability case involving the tragic death of a medically fragile infant, the parents sued a home health provider. The defendant challenged the qualifications of the parents' nurse and physician experts, arguing they were not 'practicing' at the time required by law. The El Paso Court of Appeals strictly interpreted Texas Civil Practice and Remedies Code § 74.402, finding that because the nurse had not practiced since 2021 and the doctor retired in 2019—while the claim arose in 2023—they failed the mandatory temporal requirements for experts. The court held the trial court abused its discretion in accepting the reports and reversed the ruling, though it remanded the case to allow the parents an opportunity to cure the technical deficiencies.
Litigation Takeaway
“Expert experience alone is insufficient if it is not contemporaneous with the case; to survive a motion to strike, an expert must be in active clinical practice or teaching at an accredited institution at the time the claim arose or when testimony is given. In family law cases involving medically fragile children or specialized needs, practitioners must scrutinize the 'active' status of experts to ensure their testimony is not disqualified for being out-of-date.”
