What should a doctor be aware of when cross-examined in a medical negligence case?

Doctors are used to explaining clinical decisions, but giving evidence in court is different. In a medical negligence trial, a doctor may be a defendant, a treating doctor called as a factual witness, or an expert. Each role has its own expectations. This guide covers what doctors should understand about cross-examination. It is court familiarisation; the evidence must always be truthful.

What role am I giving evidence in?

• Defendant doctor: your conduct is in issue. You give factual evidence of what you did and why.
• Treating doctor (factual witness): you give evidence of what you observed, did and recorded. You are usually not asked for independent opinions on whether the standard of care was met.
• Expert witness: you give opinion evidence. Under Order 40A of the Rules of Court 2012, an expert's duty is to help the court on matters within their expertise, and that duty overrides any obligation to the party instructing or paying them.

Knowing your role helps you avoid straying into areas you should not cover.

Why are the clinical records so important?

In most medical negligence cases, the clinical records are the backbone of the evidence. Cross-examination will often compare your evidence with:

• the timing of entries, observations and drug charts;
• what was documented about symptoms, examination findings and plans;
• consent forms and notes of discussions with the patient or family;
• referral letters, investigation results and discharge summaries.

Records made at the time can be used to refresh memory under section 159 of the Evidence Act 1950, and the other side may see and cross-examine on them (section 161). Records must never be altered after the event; see our guide on missing or altered medical records.

What legal framework will the questions reflect?

Questions often track the legal test the court applies. In Malaysia, the Federal Court in Foo Fio Na addressed the duty to advise of risks, and in Zulhasnimar confirmed the Bolam test, subject to Bolitho, for diagnosis and treatment. In broad terms, the court considers whether the doctor acted in accordance with a practice accepted as proper by a responsible body of medical opinion that withstands logical analysis, and for advice on risk, whether material risks were disclosed. See Bolam and Bolitho in Malaysian medical negligence and informed consent.

What lines of cross-examination are common?

• Timeline: "When exactly did you review the patient?"
• Documentation: "Where in the notes did you record that warning?"
• Usual practice versus memory: "Do you actually remember telling her, or is that what you usually do?"
• Alternatives: "Did you consider a CT scan at that point?"
• Guidelines: "Were you aware of the hospital protocol?"
• Consistency: comparisons with your statement, incident report or earlier letters.

How should a doctor answer?

1. Read the record before answering about it; ask for the page.
2. Distinguish memory from practice: "I don't specifically remember, but my usual practice is…, and the note shows…"
3. Stay within your role and expertise.
4. Concede fairly where a point is right. Fair concessions often strengthen credibility.
5. Avoid jargon, or explain it simply for the court.
6. Do not argue or lecture. Answer the question asked.

What should I prepare?

• A complete, paginated copy of the clinical records, including nursing notes, charts and investigation results.
• Your witness statement, re-read alongside the records to check every date and time.
• A note of anything in the records you cannot now explain, to raise with the lawyer before trial.
• Relevant hospital protocols or guidelines in force at the time, if your lawyer asks for them.
• Practical arrangements: clinic cover, leave and the whole day free for court.

Common mistakes

• Not re-reading the full records before trial.
• Presenting usual practice as specific memory.
• Defending every decision even where a fair concession is due.
• Speculating outside your specialty.
• Criticising colleagues without basis.

When to speak to a lawyer

If you are a doctor facing a claim or asked to give evidence, seek advice early, and notify your indemnity provider where relevant.

Frequently asked questions

Can I bring my own notes into court?

Only with permission. Contemporaneous clinical records may be used to refresh memory under section 159.

Should I agree with the patient's expert?

Only where you genuinely agree. Answer each point honestly.

Can I refuse to answer a question outside my specialty?

You may say it is outside your expertise. That is often the accurate answer.

Will the judge understand medical terms?

Explain them simply. Clear explanation helps the court.

What if the records are incomplete?

Say so honestly and explain what you remember, distinguishing it from usual practice.
