Medical Negligence Claims in Australia: Proof, Time Limits & Payouts

A medical negligence claim must prove 4 elements, namely a duty of care, a breach of that duty, causation and damage, and in NSW and Victoria it must generally be started within 3 years of the date the claim becomes discoverable and no later than 12 years after the treatment. The claim is brought against the doctor, hospital or other health provider under the state civil liability legislation, such as the Civil Liability Act 2002 (NSW), the Wrongs Act 1958 (Vic) and the Civil Liability Act 2003 (Qld).

To start, request a copy of your medical records and write a timeline of each appointment, what you were told and when you first noticed the problem. A lawyer will then brief an independent medical expert to test whether the care fell below accepted practice. In Queensland, an initial notice of a medical negligence claim is due within 9 months, so early advice from Medical Negligence Lawyers in Australia matters there most.

What must you prove in a medical negligence claim?

You must prove all 4 elements of negligence on the balance of probabilities. Missing any one of them defeats the claim.

1. Duty of care

A doctor, nurse, hospital or other health provider owes a duty of care to the patients it treats. This element is rarely disputed in a treatment claim.

2. Breach of duty

Breach means the care fell below the required standard. Under section 5B of the Civil Liability Act 2002 (NSW), a person is not negligent in failing to take precautions against a risk unless the risk was foreseeable, the risk was not insignificant, and a reasonable person in the same position would have taken those precautions.

For professionals, the civil liability Acts add a peer professional opinion defence. Under section 5O of the Civil Liability Act 2002 (NSW), a professional is not liable in negligence if they acted in a way that, at the time, was widely accepted in Australia by peer professional opinion as competent professional practice. The defence has limits: the court can reject a peer opinion that is irrational, differing opinions can each be relied on, and an opinion need not be universally accepted to be widely accepted.

Failure to warn of a risk

A doctor must warn a patient of material risks of a proposed treatment, a duty the High Court set out in Rogers v Whitaker (1992). In NSW, the peer professional opinion defence does not apply to the giving of, or failure to give, a warning about the risk of death or injury (section 5P). The patient must still prove that a proper warning would have changed their decision.

3. Causation

Causation means the breach caused the harm. Under section 5D of the Civil Liability Act 2002 (NSW), the patient must show that the negligence was a necessary condition of the harm (factual causation) and that it is appropriate for liability to extend to the harm (scope of liability). Under section 5E, the patient always bears the onus of proving causation. Causation is often the hardest element in delayed diagnosis claims, where the question is whether earlier treatment would have led to a better outcome.

4. Damage

The patient must have suffered actual harm, such as a physical or psychiatric injury, extra treatment, lost income or a shortened life expectancy. Some damages also depend on a severity threshold (see below).

What are the time limits for a medical negligence claim?

The time limit for a medical negligence claim is generally 3 years, but when those 3 years start depends on the state:

Different rules apply to children and to people under a disability, and the other states and territories have their own limitation Acts. A lawyer can advise whether a claim is still within time, which is the first thing to check.

Why is expert evidence needed?

Expert evidence is needed because the court decides breach and causation by reference to medical opinion. Because of the peer professional opinion defence, the health provider will usually call experts who say the care was competent practice. The patient therefore needs independent experts, usually in the same specialty as the treating doctor, to explain why the care fell below the standard and what would have happened with proper care.

Experts are usually briefed early, before proceedings start, because a claim without a supportive opinion on both breach and causation rarely proceeds. Expert reports are a major disbursement, and a costs agreement should say who pays for them if the claim fails.

How are medical negligence payouts calculated?

A medical negligence payout is calculated by adding up the patient's individual losses under several heads of damage, subject to the caps in the civil liability legislation. Payouts vary widely with the injury, age and earnings, so an average figure says little about any single claim.

The main heads of damage are:

1. Non-economic loss (pain, suffering and loss of enjoyment of life). In NSW, nothing is payable unless the loss is at least 15% of a most extreme case, and the maximum is $350,000, indexed each year and awarded only in a most extreme case (sections 16 and 17). In Victoria, damages for non-economic loss require a "significant injury": impairment of more than 5% for most injuries, 10% or more for psychiatric injury and 5% or more for spinal injury (Part VBA, Wrongs Act 1958).
2. Past and future loss of earnings. In NSW, the court disregards earnings above 3 times average weekly earnings (section 12).
3. Future losses discounted to present value. In NSW, a 5% discount rate applies unless the regulations prescribe another rate (section 14).
4. Medical, hospital and rehabilitation expenses, past and future.
5. Care, including paid care and, within limits, unpaid care provided by family (section 15).
6. Loss of superannuation entitlements (section 15C).

The Personal Injury Compensation Amounts in Australia guide explains these heads of damage across all injury claims.

Which court cases shaped medical negligence law?

Two High Court decisions are cited in most medical negligence claims about warnings:

1. Rogers v Whitaker (1992): a doctor must warn a patient of material risks of a proposed treatment, and the standard is not set only by what other doctors would do.
2. Wallace v Kam (2013): a doctor who failed to warn of one risk was not liable for a different risk that materialised, because the patient would have accepted that other risk.

Later cases apply these principles together with each state's civil liability Act. Published judgments of the state Supreme, District and County Courts show how recent claims were decided.

What if you are the doctor or hospital?

A health provider who receives a letter of claim or a pre-court notice usually notifies its professional indemnity insurer, which appoints lawyers to respond. In Queensland, the respondent must give a preliminary response to a notice of claim under section 10 of the Personal Injuries Proceedings Act 2002 (Qld). Defence lawyers test the patient's expert evidence on breach and causation and rely on peer professional opinion where it supports the care given.

Finding a medical negligence lawyer

A medical negligence lawyer tests the claim with an expert opinion before any proceedings are filed, and checks the time limit first.
