Background
The plaintiffs sued defendants for medical malpractice involving pediatric hematology and oncology treatment. The trial court issued a case management order requiring all parties to exchange expert reports by October 30, 2024. The plaintiffs, however, did not provide their expert Elizabeth Peralta’s report until April 16, 2026—approximately eighteen months after the deadline. The defendants filed a motion to strike Peralta’s expert testimony, arguing that the severe delay and insufficient notice prejudiced their ability to retain a competing expert within the three months remaining before trial.
The trial court denied the defendants’ motion, allowing the expert to testify. The defendants sought supervisory review from the appellate court, arguing the trial court abused its discretion in permitting the late disclosure.
The Court’s Holding
The Louisiana Court of Appeal, First Circuit denied the writ of supervisory review in a 3–2 decision, upholding the trial court’s decision to allow the expert testimony. The majority did not issue a written opinion explaining its reasoning, issuing only the ruling “Writ Denied.”
The dissenting judges (Penzato and Greene, JJ.) would have granted the writ and struck the expert. The dissent found that the trial court abused its discretion. Under Louisiana Code of Civil Procedure Article 1551, when a party violates a pretrial order, the court may impose sanctions including prohibiting the disobedient party from introducing designated evidence. The dissent reasoned that an eighteen-month delay in producing an expert report constitutes flagrant disobedience and that the compressed three-month window prejudiced the defendants’ ability to prepare a responsive expert.
Key Takeaways
- Expert disclosure deadlines are serious procedural requirements, and egregious violations may warrant sanctions including striking testimony.
- The court split 3–2 on whether the trial judge properly exercised discretion, showing significant disagreement on the appropriate remedy for severe delays.
- Louisiana courts may prohibit the introduction of evidence as a sanction for pretrial order violations, though application depends on case-specific prejudice.
- The proximity of trial (three months remaining) affects the degree of prejudice from late disclosures.
Why It Matters
This case highlights the ongoing tension in civil procedure between strict enforcement of discovery deadlines and allowing cases to proceed on their merits. The dissent’s view—that an eighteen-month delay and three-month notice window warrant striking testimony—reflects the principle that trial preparation requires adequate time. However, the majority’s decision to allow the testimony suggests that trial courts retain discretion to balance procedural violations against the desire to adjudicate cases fully.
For practitioners, the decision underscores that even substantial discovery violations do not automatically result in exclusion of evidence, and that trial courts have considerable discretion in managing procedural noncompliance. The close vote and absence of a majority opinion leave the precise standard for striking evidence after late disclosure somewhat unsettled.
