The Puerto Rico Court of Appeals has denied a petition from Jonathan O. Duluc and others to reverse a lower court's ruling in a medical malpractice case against Dr. Pedro N. Ciprian Liranzo. This decision, made on May 26, 2026, affects how expert testimony is handled in medical negligence cases, particularly regarding the timing of expert reports.
The case arose when Duluc and others filed a petition for certiorari, seeking to challenge an order from the San Juan Superior Court. The order required that a preliminary expert report be submitted before Dr. Ciprian could be deposed. The court's decision is significant because it clarifies the expectations for expert testimony in malpractice cases, which can influence future legal proceedings.
The parties involved in this case are Jonathan O. Duluc, Iván Robles, and Barbara Robles, who are the petitioners, and Dr. Pedro N. Ciprian Liranzo, who is the respondent. The dispute centers on the requirement for a preliminary expert report before taking the deposition of Dr. Ciprian. The petitioners argued that the discovery process was still in its early stages and that they had complied with their procedural obligations. They contended that Dr. Peter A. Goulden, their expert, could not provide a final opinion on the alleged medical negligence until further essential documentary and testimonial evidence was produced.
In response, Dr. Ciprian filed a motion opposing the petitioners' request for reconsideration. He argued that the petitioners were merely reiterating previously rejected arguments. Dr. Ciprian asserted that the petitioners needed to provide a preliminary expert report to prepare adequately for his deposition. He emphasized that in medical malpractice cases, there is a presumption of correctness in favor of the physician, which can only be overcome with adequate expert testimony.
The San Juan Superior Court ruled against the petitioners on March 24, 2026, denying their request for reconsideration. The petitioners then filed their certiorari petition on April 23, 2026, claiming that the lower court had abused its discretion and misinterpreted the Civil Procedure Rule 23.1, which governs expert testimony.
In its ruling, the Court of Appeals, led by Judge Álvarez Esnard, stated, "The Petitioner has not demonstrated that the lower court exceeded its discretion or misinterpreted the law." The court concluded that the circumstances did not warrant intervention in the lower court's decision, emphasizing that the petitioners failed to show that not intervening would result in an irreparable failure of justice.
This ruling carries significant implications for future medical malpractice cases in Puerto Rico. It reinforces the necessity for plaintiffs to provide preliminary expert reports before depositions, which may affect how cases are prepared and presented. The decision also highlights the court's discretion in managing procedural matters related to expert testimony.
Going forward, this ruling sets a precedent that could influence how medical malpractice cases are approached in Puerto Rico. It underscores the importance of adhering to procedural requirements and the need for plaintiffs to be prepared with expert testimony early in the litigation process.
Details were not available in the court filing regarding whether the petitioners plan to appeal this decision further or if there are related cases pending. However, the ruling stands as a crucial interpretation of procedural rules governing expert testimony in medical negligence cases.
