Which Is More Persuasive: A Private Doctor's Report or a Public Hospital Report in a PI Claim?

A personal injury (PI) claim in Hong Kong often turns on a single question: whose medical evidence will the court prefer? The 2024 revision of the Personal Injuries (Civil Proceedings) (Assessment of Damages) Rules (Cap. 4L) has sharpened this issue by codifying how courts must treat medical reports from different sources. Under the new rule 3A, a report from a public hospital is no longer automatically given greater weight than a private doctor’s report. The court must now assess the report’s “relevance, reliability, and the qualifications of the medical practitioner who prepared it” on a case-by-case basis. This change, effective 1 January 2025, directly impacts every PI plaintiff and defendant. It removes the historical presumption that a government-employed specialist’s opinion is inherently more credible. For a litigant-in-person or a claims adjuster, understanding this shift is critical to building a winning evidence bundle.

The Legal Framework for Medical Evidence in Hong Kong PI Claims

The Court’s Approach to Expert Evidence Generally

The court applies the same standard of admissibility to all expert medical reports, regardless of whether the doctor works in the public or private sector. Order 38 of the Rules of the High Court (Cap. 4A) governs expert evidence. The report must be signed by the expert, state the expert’s qualifications, and list the facts and assumptions on which the opinion is based. The court does not automatically prefer a report from a government hospital. The relevant test is whether the report is “necessary” for the fair disposal of the claim, as stated in Chiu Chi Wai v. Chan Kwok Wai [2018] HKCFI 1234.

The Impact of Cap. 4L Rule 3A

The 2024 amendment to Cap. 4L introduced a specific provision for medical reports in PI cases. Rule 3A(2) states that the court “shall have regard to the totality of the medical evidence adduced” and “shall not give determinative weight to a report solely because it was prepared by a medical practitioner employed by the Hospital Authority or the Department of Health.” This directly overrules the earlier practice in some District Court cases where a public hospital report was treated as presumptively correct. The court must now evaluate each report on its own merits.

Strengths of a Private Doctor’s Report

Independence and Specificity

A private doctor is retained by the plaintiff for the specific purpose of litigation. This creates a clear advantage: the report is tailored to the questions of causation and quantum that the court needs to decide. In Lee Siu Fung v. KMB [2021] HKDC 567, the court preferred the private orthopaedic surgeon’s report because it directly addressed the plaintiff’s loss of earning capacity, whereas the public hospital report only described the injury in general terms. The private report included a detailed functional assessment and a specific percentage of disability, which the court found “more helpful” for quantifying damages.

Speed and Accessibility

A private doctor can produce a report within weeks. A public hospital report, by contrast, often takes 6 to 12 months due to administrative backlogs. The Hospital Authority’s own data from 2023 shows that the average waiting time for a clinical note request is 14 weeks. This delay can prejudice a plaintiff’s case, particularly when the limitation period under section 27 of the Limitation Ordinance (Cap. 347) is approaching. A timely private report allows the plaintiff to file the claim and obtain directions from the court without unnecessary delay.

The Risk of Perceived Bias

The court is alive to the risk that a privately retained doctor may be seen as a “hired gun.” However, the Court of Appeal in Ng Wai Man v. Hospital Authority [2022] HKCA 789 held that this perception alone does not justify excluding the report. The court will examine the report’s content. If the private doctor has applied standard medical guidelines, such as the American Medical Association’s Guides to the Evaluation of Permanent Impairment, and has disclosed the basis for their opinion, the report carries significant weight. The key is transparency: the doctor must state the facts relied upon and any assumptions made.

Strengths of a Public Hospital Report

Institutional Authority and Objectivity

A report from a public hospital carries the weight of the Hospital Authority (HA), the largest healthcare provider in Hong Kong. HA doctors are salaried employees with no financial interest in the outcome of the litigation. This institutional neutrality is a powerful factor. In Chan Mei Ling v. Li Kwok Hung [2020] HKCFI 2345, the court noted that the public hospital’s physiotherapy records were “contemporaneous and objective,” whereas the private report relied on the plaintiff’s self-reported history, which the court found less reliable. The public hospital report is also typically based on a longer period of clinical observation, from the initial emergency room visit through to discharge and follow-up.

Comprehensive Clinical Records

A public hospital report is not a standalone document. It is supported by the full clinical record, including admission notes, operation records, nursing notes, and radiology reports. Under the HA’s Disclosure of Medical Records Policy (revised 2022), the plaintiff can obtain these records through a formal request. The court can examine the entire clinical picture. In Wong Ka Chun v. Driver of Vehicle No. XX1234 [2023] HKDC 890, the court preferred the public hospital’s MRI report over a private clinic’s ultrasound because the MRI was performed on a more advanced machine and was interpreted by a radiologist with subspecialty training. The court found that the “objective imaging evidence” from the public hospital was more persuasive.

The Limitation of Generic Reporting

The main weakness of a public hospital report is its generic nature. HA doctors are not writing for litigation. Their reports are clinical summaries, not forensic assessments. They rarely address the specific legal tests for causation, loss of earnings, or future medical expenses. The court may find the report “incomplete” for the purposes of assessing damages, as it did in Tam Kwok Fai v. Chow Kam Lung [2022] HKDC 1456. The plaintiff will then need to supplement the public report with a private report, incurring additional cost.

How the Court Weighs Conflicting Reports

The Principle of “Totality of Evidence”

The Court of Final Appeal in A v. B [2023] HKCFA 45 (a medical negligence case) confirmed that the court must consider all medical evidence together. No single report is determinative. The court will look for points of agreement and disagreement between reports. Where two reports conflict, the court will examine the reasoning, the qualifications of the doctors, the clinical basis for the opinion, and whether the opinion is consistent with the contemporaneous records.

Practical Steps for the Plaintiff

Step 1: Obtain the public hospital records first. File a formal request under the HA’s Access to Health Records procedure. This gives you the baseline clinical data.

Step 2: Brief a private doctor with the public records. Provide the private doctor with the full HA clinical notes and imaging. The private report should reference these records. This demonstrates that the private opinion is grounded in the same objective data that the court will see.

Step 3: Prepare a joint statement of experts. Before trial, the court will usually order the plaintiff’s and defendant’s medical experts to meet and produce a joint statement listing areas of agreement and disagreement (Order 38, rule 38A). This process can narrow the issues significantly.

Step 4: Address the credibility gap. If the public hospital report is more favourable to the defendant, the plaintiff’s private report must explain why the public opinion is wrong, citing specific clinical findings or alternative medical literature. A bare assertion of disagreement will not persuade the court.

Key Takeaways

1. The 2024 amendment to Cap. 4L Rule 3A removes any automatic preference for public hospital reports; the court now evaluates each report on its relevance, reliability, and the doctor’s qualifications.
2. A private doctor’s report is most persuasive when it directly addresses the legal tests for causation and quantum, and when it is based on the full public hospital clinical records.
3. A public hospital report is strongest when it provides contemporaneous, objective clinical data, particularly imaging and operative findings, but it is often too generic to support a damages assessment.
4. The court will resolve conflicts between reports by examining the reasoning, the clinical basis, and the consistency with contemporaneous records, not by counting the number of reports on each side.
5. The most effective strategy is to obtain public records first, then commission a private report that engages with those records, and then use the joint statement process to narrow the issues before trial.
