Right to Refuse Treatment Victoria

The Right Is Absolute — With One Narrow Exception

Under Victorian law, a competent adult has an absolute right to refuse any medical treatment, even if that refusal will result in their death. No court order, no family member's plea, and no clinical judgment about what's "in the patient's best interests" can override a competent refusal.

This right is grounded in common law (the principle of bodily autonomy) and reinforced by the Medical Treatment Planning and Decisions Act 2016, which extends the refusal right into the future through instructional directives in an Advance Care Directive (ACD). A valid instructional directive refusing specific treatment carries the same legal force as a contemporaneous refusal by a patient with full capacity.

The one narrow exception: the Mental Health and Wellbeing Act 2022 allows an authorised psychiatrist to override treatment preferences — including those in an ACD — for a patient subject to a compulsory treatment order, but only for mental health treatment and only under strict statutory conditions. For all other medical treatment, the refusal stands.

How Treatment Refusal Works in Practice

While you have capacity, you can refuse treatment directly. A doctor must explain the consequences of refusal, and you must demonstrate that you understand them. But understanding the consequences and accepting them is your right — the doctor cannot proceed over your objection.

If you lose capacity, your ACD takes over. An instructional directive that refuses specific treatment — "I refuse cardiopulmonary resuscitation," "I refuse mechanical ventilation if there is no reasonable prospect of independent breathing" — is legally binding on treating clinicians. They must follow it as if you were making the refusal in person.

If you have no ACD, your Medical Treatment Decision Maker (MTDM), or the first available person in the statutory hierarchy, makes decisions on your behalf. They should make decisions consistent with your known values and preferences. If those aren't known, they must act in your best interests.

What Clinicians Can and Cannot Do

Clinicians cannot: treat you against your documented wishes if you have a valid instructional directive refusing that treatment. They cannot argue that the treatment is in your best interest, that your family wants it, or that refusing would be unwise. The refusal is legally binding.

Clinicians can: provide emergency treatment if no ACD or MTDM can be located and the patient lacks capacity. This is the emergency treatment exception — when there's an immediate risk of serious harm, and the clinician has made reasonable efforts to find a directive or decision-maker, they can provide treatment necessary to prevent that harm. This does not authorise ongoing treatment over a patient's documented objections.

Clinicians must: follow Goals of Patient Care (GOPC) orders that translate your ACD into clinical protocols. If your ACD says you refuse CPR, the treating team should enter a corresponding clinical order so that nursing staff, after-hours doctors, and paramedics know not to resuscitate.

The Phrasing Problem

The legal right to refuse treatment is clear. The practical challenge is writing refusals in language that clinical teams can act on without hesitation.

Consider the difference:

• "No heroic measures" — What does "heroic" mean? Is a blood transfusion heroic? Is an IV antibiotic heroic? Different clinicians will interpret this differently, and the ambiguity may lead them to provide treatment you wouldn't have wanted, or to withhold treatment you would have accepted.

• "I refuse cardiopulmonary resuscitation (CPR) and mechanical ventilation in any circumstance where the treating medical practitioner determines there is no reasonable prospect of recovery to a state where I can breathe independently and recognise family members" — This is specific, clinically actionable, and directly translatable into a hospital resuscitation order.

The second version takes longer to write, requires a conversation with your GP, and demands that you think carefully about exactly where your lines are. That specificity is what makes the difference between a directive that gets followed and one that gets set aside as too vague to interpret.

Treatment You Cannot Refuse in Victoria

Two categories of treatment fall outside the standard refusal framework:

Compulsory mental health treatment. If you're subject to a treatment order under the Mental Health and Wellbeing Act 2022, an authorised psychiatrist can administer mental health treatment without your consent. This includes medication, but electroconvulsive therapy (ECT) requires a separate order from the Mental Health Tribunal. If the psychiatrist overrides your ACD, they must provide written reasons.

Treatment required by law. In rare circumstances, public health legislation may require treatment — for example, quarantine measures during a declared public health emergency. These situations are governed by separate statutes and fall outside the ACD framework.

Refusing Treatment Is Not the Same as Choosing to Die

Refusing life-sustaining treatment is a legal right, not a form of suicide or euthanasia. Victorian law is clear on this distinction. A patient who refuses CPR or mechanical ventilation is exercising their right to bodily autonomy — choosing not to accept a specific medical intervention. Clinicians who respect a valid treatment refusal are fulfilling their legal obligations, not assisting in death.

Voluntary Assisted Dying (VAD) is a separate legal process under the Voluntary Assisted Dying Act 2017, with its own eligibility criteria, request process, and safeguards. A treatment refusal in an ACD and a VAD request are two entirely different legal instruments.

The Victoria Advance Directive & Living Will Kit includes clinician-approved phrasing templates for treatment refusals that translate your values into specific, unambiguous clinical language — so your refusal is clear enough that no clinician has to guess what you meant.
