Summary

This High Court decision arose in the context of a medical negligence action brought by the executrix of a deceased patient’s estate. The first defendant had performed a knee replacement surgery on 1 November 2016. Complications developed the next day, and the patient ultimately died on 7 November 2016 after further surgical interventions, including an above-knee amputation. The plaintiff sued the surgeon, the hospital where the surgery took place, and a company associated with the clinic where the surgeon practised.

The procedural dispute in the appeal was narrow but important: whether, under the High Court Protocol for Medical Negligence Cases (“the Protocol”), defendants must file and serve independent medical expert reports in support of their defences at the same time as they file their defence, in the “spirit” of the Protocol’s requirement that plaintiffs attach medical expert reports when filing their statements of claim. The plaintiff’s counsel sought directions from the assistant registrar, and when that request was refused, the plaintiff appealed.

The High Court struck out the appeal as irregular. While the judge also addressed the substantive misunderstanding of the Protocol, the decisive issue was procedural: the appeal was filed against an assistant registrar’s response to a letter, and the judge emphasised that letters are not court orders and do not engage the appeal procedure under the Rules of Court. The court therefore treated the appeal as procedurally improper and ordered that it be struck out, with costs reserved for later determination.

What Were the Facts of This Case?

The underlying claim concerns the medical treatment of Madam Yuen Ingeborg Nee Santjer (“Madam Yuen”). On 1 November 2016, the first defendant, a surgeon, performed a knee replacement surgery. The following day, complications developed. The first defendant had already left the hospital earlier that day to travel overseas, leaving the patient’s subsequent management to other doctors.

According to the statement of claim, three doctors took over the management of Madam Yuen and performed a second surgery. Despite this intervention, her condition did not improve. The plaintiff alleged that Madam Yuen developed multiple organ failure. In an attempt to save her, her leg was amputated above the knee. The plaintiff further alleged that the amputation also failed to arrest her deterioration.

Madam Yuen’s condition continued to worsen, and she eventually passed away on 7 November 2016. The plaintiff, who is the executrix of Madam Yuen’s estate, brought the action on behalf of the estate. The plaintiff’s pleaded case therefore framed the dispute as one of medical negligence and causation, with the alleged failures occurring in the peri-operative and post-operative management of the patient.

In terms of parties, the plaintiff sued: (a) the first defendant surgeon; (b) the second defendant, Parkway Hospitals Singapore Pte Ltd trading as Mount Elizabeth Hospital, as the party responsible for management of the hospital where the surgery took place; and (c) the third defendant, VS Investment Holdings Pte Ltd formerly known as Ardmore Orthopaedics Pte Ltd, as the company managing the clinic in which the first defendant practised. The judgment notes that the clinic itself was not named as a party, but that point was not before the judge in this appeal.

Although the underlying action is a medical negligence suit, the legal issues in this appeal were primarily procedural and interpretive. First, the court had to consider whether the High Court Protocol for Medical Negligence Cases requires defendants to file and serve independent medical expert reports in support of their defences at the time they file their defence, mirroring the Protocol’s requirement that plaintiffs attach expert reports when filing their statements of claim.

Second, the court had to determine whether the plaintiff’s “appeal” was properly brought. The appeal was directed against an assistant registrar’s refusal communicated through a letter responding to the plaintiff’s counsel’s request. The judge therefore had to consider whether such a letter could be treated as an appealable decision engaging the appeal procedure under the Rules of Court.

In other words, the case presented two interlocking questions: (i) what the Protocol actually means in practice and how it should be applied to the exchange of expert evidence; and (ii) whether counsel complied with the procedural requirements for bringing a matter before the court, as opposed to relying on correspondence.

How Did the Court Analyse the Issues?

The judge began by addressing counsel’s interpretation of the Protocol. The plaintiff’s counsel, Mr Edmund Kronenburg, had requested that the defendants file and serve independent medical expert reports in support of their defences, and that the plaintiff be given two weeks thereafter to file and serve replies. Counsel’s position was that paragraph 4 of Appendix J of the Supreme Court Practice Directions (the Protocol) had changed the “paradigm” of practice: since plaintiffs must attach expert reports when filing their statements of claim, defendants should likewise attach expert reports when filing their defences, “in the spirit of the Protocol”, to facilitate fair exchange and early resolution.

The judge rejected this as a misunderstanding. The reasoning was grounded in the structure and timing of pleadings in medical negligence cases. The court emphasised that in such cases, the plaintiff has up to three years to file the statement of claim before the action becomes time-barred. By contrast, the defendant has only two weeks to file a defence once served with the claim. This asymmetry affects how and when expert evidence can realistically be obtained and deployed.

Further, the judge explained the practical expectations at the pleading stage. When a plaintiff files a claim, the plaintiff is expected to be ready to proceed and should not file without knowing whether there is medical evidence to support the claim. The Protocol’s requirement that plaintiffs attach medical expert reports early is therefore designed to ensure that the claim is properly supported from the outset, rather than being followed by requests for time to obtain expert evidence after filing.

By contrast, the judge noted that the defendant is not necessarily obliged to call medical expert evidence if the defence can neutralise, or even destroy, the plaintiff’s medical evidence without the need for the defendant to adduce its own expert report. In that sense, the Protocol is not intended to impose a rigid requirement that both sides must file expert reports simultaneously at the defence stage. The Protocol’s purpose is to expedite the action by having the plaintiff’s medical evidence filed early, not to create an automatic reciprocal obligation on defendants.

Having clarified the substantive point, the judge then addressed the procedural defect that ultimately determined the appeal. The appeal was filed against the assistant registrar’s letter responding to counsel’s request. The judge held that letters are not court orders and do not bring into play the appeal procedure under the Rules of Court. The judge’s remarks were pointed: “Letters are mere epistles”, and some may be of “love” or “hate”, but they are not official orders that trigger formal appellate mechanisms.

The court underscored that where a party wishes to be heard by the court, the proper procedure is to file an application. The judge cautioned against any notion that modern practice, which aims for trim and speedy resolution in the interests of clarity and access to justice, has displaced the importance of procedure. The court therefore treated the plaintiff’s approach—appealing against a letter—as irregular.

In doing so, the judge distinguished between informal correspondence and formal judicial decisions. The Rules of Court provide the procedural framework for applications and appeals. A party cannot bypass that framework by treating correspondence as if it were an order. The judge’s analysis thus reflects a consistent judicial concern: procedural compliance is not a technicality; it is the mechanism by which the court’s jurisdiction is properly engaged and by which parties receive fair notice of decisions and the opportunity to respond through the correct procedural channels.

What Was the Outcome?

The High Court struck out the appeal as irregular. The judge characterised striking out as the proper order rather than dismissal, because dismissal assumes that there were merits in both substance and procedure. Here, the procedural defect was fundamental: the appeal was directed against a letter rather than an appealable decision or order.

Costs were ordered to be “costs thrown away” to the three defendants. The judge indicated that costs would be fixed at a later date if the parties could not agree. Practically, this means the plaintiff’s attempt to obtain the requested expert-report directions through an irregular appeal route resulted in wasted costs and did not advance the procedural management of expert evidence in the underlying medical negligence action.

Why Does This Case Matter?

This decision is significant for two reasons. First, it clarifies the operation of the High Court Protocol for Medical Negligence Cases in relation to expert evidence. Practitioners sometimes read the Protocol’s early-expert-report requirement for plaintiffs as implying a reciprocal obligation on defendants. The court’s reasoning shows that the Protocol is not a symmetrical “swap” of expert reports at the pleading stage. Instead, it is a targeted case-management tool designed to expedite proceedings by ensuring that the plaintiff’s medical evidence is filed early, taking into account the different time constraints faced by plaintiffs and defendants.

For lawyers, the case reinforces that the Protocol should be applied with attention to the procedural realities of limitation periods and pleading timelines. A defendant’s obligation to file expert evidence is not automatically triggered merely because the plaintiff has attached an expert report. The defence may be able to respond through other means, including by challenging the plaintiff’s evidence without necessarily requiring its own expert report at the defence stage. This can affect litigation strategy, including how counsel assesses the strength of the plaintiff’s case and whether expert evidence is needed early or can be deferred.

Second, the case is a cautionary procedural authority. The court’s insistence that letters are not orders and that appeals must be brought through proper applications under the Rules of Court is a reminder that procedural shortcuts can be fatal. Even where the substantive argument about the Protocol might have been arguable, the court will not entertain an irregular appeal. For practitioners, the case underscores the importance of identifying the correct procedural vehicle—application, summons, or appeal—depending on the nature of the decision being challenged.
