Charged with choking, suffocation or strangulation in NSW.

Section 37 of the Crimes Act 1900 (NSW) creates three offences for choking, suffocation and strangulation. The maxima are 5 years, 10 years, and 25 years depending on the conduct and the accused's state of mind. The charges are frequently laid in family-violence matters, often alongside common assault, AOABH, and contravene-AVO charges. The framing of the charge, and which subsection is pursued, shape the entire matter.

The legislative source.

Section 37 Crimes Act 1900 (NSW) · Choking, suffocation and strangulation
The section creates three offences:
s 37(1A) Intentionally choking, suffocating or strangling another person without that person's consent. Maximum penalty: imprisonment for 5 years.
s 37(1) Intentionally choking, suffocating or strangling another person so as to render that person unconscious, insensible or incapable of resistance, being reckless as to rendering the other person unconscious, insensible or incapable of resistance. Maximum penalty: imprisonment for 10 years.
s 37(2) Choking, suffocating or strangling another person so as to render that person unconscious, insensible or incapable of resistance, with the intention of enabling the accused (or assisting another person) to commit another indictable offence. Maximum penalty: imprisonment for 25 years.

s 37(3) In this section, "another indictable offence" means an indictable offence other than an offence against this section.

Section 37 was rewritten by the Crimes Amendment (Strangulation) Act 2014 (NSW), and the lower-tier offence (intentional choke without consent) was added by the Crimes Legislation Amendment Act 2018. The three offences are now graduated by the conduct (whether or not the victim was rendered unconscious / insensible / incapable) and by the accused's state of mind (intent to commit another indictable offence elevates the matter to the 25-year band).

The conduct element is satisfied by any application of pressure to the throat or neck, or by interference with breathing. The choking does not need to leave a visible mark. The rendering of unconsciousness or insensibility is a separate factual question and is not required for the basic offence.

Consent is a defence to the basic offence but not the higher-tier offences. Consent is rarely advanced in family-violence settings; where it is, it is squarely contested by the Crown.

Penalties and likely outcomes.

The basic offence (5-year maximum).

For a first-offence basic-tier matter with no aggravating features, a CCO or short ICO is realistic. Section 10 outcomes are uncommon because the offence carries the family-violence overlay even where the underlying conduct is at the lower end. Where the matter resolves on a plea with a strong subjective case and the conduct is at the lower end, an ICO of 12 to 18 months is achievable.

The intermediate offence (10-year maximum).

Once the victim has been rendered unconscious, insensible or incapable of resistance, the sentencing posture changes. Full-time custody is the realistic starting point for matters with any aggravating feature (prior family-violence record, breaches of an AVO, vulnerable victim). ICO of 18 to 30 months is the lower end where the subjective case is strong.

The aggravated offence (25-year maximum).

The most-aggravated form is strictly indictable in the District Court. Full-time custody for a substantial period is the realistic outcome. The matter is treated as one of the most serious in the family-violence framework.

Defences and arguments worth running.

The conduct.

The Crown must prove choking, suffocation or strangulation. Where the conduct was a single push or grip that did not interfere with breathing or impede the throat or neck, the section's conduct element is not engaged. Medical evidence (presence or absence of petechial haemorrhages, neck bruising, voice changes) is a frequent battleground.

Lack of intent.

For the basic and aggravated offences, the Crown must prove intention. Inadvertent contact during a wider altercation does not satisfy the section. Where the conduct was incidental to a different offence (a struggle in the course of an assault), the intent element is contestable.

Lack of recklessness (intermediate offence).

The 10-year offence requires recklessness as to the consequence (unconsciousness, insensibility, incapacity). Where the accused could not reasonably foresee that consequence, the recklessness element is not made out.

Consent (basic offence).

Consent is a defence to the basic offence only. The defence is run carefully where applicable; in family-violence settings it is rarely the right path.

Identification and continuity.

Where the incident was not witnessed independently and the medical evidence is contested, identification and the continuity of the medical examination become live trial issues.

What we do for clients facing this charge.

The first task is to identify which of the three offences has been laid. The framing of the matter at the police-court stage often shapes whether the charge can be reduced to the lower-tier offence on plea negotiation. Early engagement with the Crown on the level of the charge is one of the most useful steps in a section 37 matter.

The complainant's statement is the central piece of evidence in most section 37 matters. We obtain the brief promptly and analyse the statement against any medical evidence, BWC footage and corroborative material. Inconsistencies are documented and addressed.

For matters that resolve on plea, the strategy is to keep the matter at the lowest defensible tier, build a careful subjective case (mental health context where applicable, no prior record, rehabilitation work, restorative material where appropriate), and present a draft set of conditions for any ICO or CCO. For matters that proceed to defended hearing, the brief is run hard on the conduct, intent and recklessness elements.

What we tell clients on the first call.

The practical detail below is not legal advice for your matter. It is the version of the conversation the firm typically has with a client charged with choke, suffocate or strangle in the first hour.

What evidence police usually rely on.

The complainant's statement, body-worn video at the call-out, photographs of marks on the neck, medical evidence including any laryngeal findings, and any 000 audio recording.

What to bring to the first consultation.

  • The Court Attendance Notice (or charge sheet) and any bail papers.
  • Anything police gave you in writing — fact sheet, certificate of analysis, search warrant copy, property seizure record.
  • A short written timeline of the day, in your own words.
  • A written timeline of the relationship and any prior court orders (AVO, FVO, parenting orders); a list of any witnesses to the relationship over the relevant period.

Common mistakes in the first twenty-four hours.

  • Talking to anyone other than your lawyer about the matter. Friends, family, co-accused and social media are not privileged.
  • Deleting messages, photographs, posts or browser history. The trail left by deletion is often more damaging than what was there.
  • Contacting the complainant or any prosecution witness, even through a third party.
  • Any contact with the complainant. Even a single text in breach of an interim AVO is a fresh charge that runs alongside the substantive matter.

What not to say to police without advice.

You must give your name and address. You do not have to answer anything else, and in most cases you should not. The standard answer is: “I do not wish to answer questions. I want to speak to my lawyer.” Section 89 of the Evidence Act 1995 (NSW) protects silence; the narrow section 89A exception applies only on indictable matters and only where a special caution has been given in the presence of an Australian lawyer.

The timeline you can expect.

From charge to first court appearance is typically two to six weeks in the Local Court and longer where the matter is indictable. The brief of evidence is served by the prosecutor on a date set at the first mention. From service of the brief to first reply is typically twenty-eight days. Defended hearings and committals are then listed weeks or months out depending on the court list.

When an early plea may or may not be appropriate.

An early plea attracts a sentencing discount of up to twenty-five per cent if entered at the first available opportunity, but it locks in a conviction. The firm does not advise an early plea before the brief is served and read. Choke matters under section 37 are strictly indictable in their aggravated form. We do not advise an early plea before the brief is read in full.

Court-specific notes.

If the matter is listed at the Downing Centre, Parramatta, Penrith, Burwood, Manly, Newtown, Waverley, Hornsby or Sutherland Local Court, the firm appears in person. Wollongong Local Court matters are run from the firm's Wollongong office. ACT Magistrates Court and ACT Supreme Court matters are run from chambers; the firm appears in person at all ACT mentions.

Frequently asked.

How serious are these charges?

Very. Even the basic offence (5-year maximum) is treated as a serious assault. The two higher-tier offences (10 and 25 years) are at the upper end of the assault calendar. Bail is not always granted; show-cause considerations may apply for the higher-tier offence in some circumstances.

Can a section 10 be achieved?

Rare. The family-violence overlay and the legislative seriousness of section 37 make section 10 outcomes uncommon. For the basic offence at the lowest end with a strong subjective case and a careful plea negotiation, it is achievable but not the realistic starting point. The early-plea discount and a careful subjective case are usually the better path.

Will the complainant have to give evidence?

If the matter proceeds to a defended hearing, the complainant will be required to give evidence. In family-violence matters this is often the central tactical question. Where the complainant has indicated they do not wish to proceed, the prosecution may still continue under the family-violence framework. We address this carefully and conservatively.

How does this interact with the AVO?

An AVO will almost always be sought alongside the criminal charge. The AVO is determined on the civil standard and the conditions are usually imposed by consent without admission. The criminal charge runs separately. Our note on contravene-AVO matters explains the consequences of breach.

Is consent ever a defence?

Only to the basic offence under section 37, and even then it is rarely the right path in family-violence settings. The two higher-tier offences cannot be answered by consent.

Can I plead to a lesser charge?

The most common negotiation is between the three tiers of section 37, and between section 37 and common assault or AOABH. Whether a lesser charge is accepted by the Crown turns on the strength of the evidence and the seriousness of the conduct as the Crown views it.
