Choking and Strangulation in NSW: Why “Consent” Can Still Lead to Prison

Why choking is treated differently under NSW criminal law

Choking and strangulation offences are among the most misunderstood areas of domestic and sexual violence law in New South Wales. Many accused people believe that if the act occurred during consensual sexual activity, criminal liability cannot arise. That assumption is dangerously wrong. NSW law treats choking as an inherently dangerous act because of its strong association with serious injury and homicide, particularly in domestic contexts.

Medical and criminological research has repeatedly shown that non-fatal strangulation is one of the strongest predictors of later domestic homicide. This evidence underpins why NSW courts approach choking allegations with particular seriousness, even where the complainant initially appeared to consent or did not immediately seek medical attention.

The legal framework: choking as an offence in NSW

Choking is criminalised under section 37 of the Crimes Act 1900 (NSW), which makes it an offence to intentionally choke, suffocate or strangle another person without their consent. The legislation expressly recognises the dangerousness of pressure applied to the neck, given the risk of interrupting blood flow to the brain rather than airflow alone.

The offence carries a maximum penalty of five years’ imprisonment, which increases where the conduct occurs in a domestic context. You can read the full provision in the consolidated Crimes Act 1900 (NSW) published by the NSW Government, which sets out the elements the prosecution must prove and the applicable penalties.

A critical feature of the offence is that consent is tightly constrained. Even where sexual activity is consensual, the law does not permit consent to conduct that causes serious harm or renders a person incapable of withdrawing consent. Once pressure is applied to the neck in a way that restricts blood flow, causes dizziness, panic, loss of consciousness or inability to resist, consent is no longer legally effective.

Judicial guidance on consent and harm

The Judicial Commission of New South Wales, in its guidance on offences involving violence, emphasises that consent must be informed, ongoing and capable of being withdrawn. Conduct that incapacitates a person undermines the very foundation of consent. Courts are therefore sceptical of arguments that choking was consensual where evidence suggests panic, fear, loss of consciousness or subsequent injury.

NSW courts have long held that consent does not excuse violence that causes actual bodily harm unless it falls within narrow, socially accepted categories. This principle is reflected in appellate authority dealing with violent conduct in intimate contexts, and continues to inform how choking matters are assessed at both trial and sentence.

Sentencing principles applied by the courts

When sentencing choking offences, courts apply the general purposes of sentencing set out in the Crimes (Sentencing Procedure) Act 1999 (NSW), with particular emphasis on denunciation and general deterrence. The Judicial Commission’s sentencing guidance on violent and domestic violence offences makes clear that choking is treated as objectively serious because of the high risk of catastrophic harm, even where injury is not immediately apparent.

Aggravating factors include the duration of the choking, the amount of force used, whether the complainant experienced fear or panic, any loss of consciousness, and whether the offence occurred in a domestic relationship. Courts also treat prior AVOs or a history of controlling behaviour as significant aggravating features.

Mitigating factors may include limited duration, absence of injury, early plea and genuine remorse, but NSW sentencing decisions consistently show that choking is rarely regarded as trivial. Full-time imprisonment is well within range where the conduct involved sustained pressure or significant fear.

Evidence and investigation in choking matters

Choking cases often rely on a combination of medical evidence, photographs, witness accounts and admissions made in police interviews or text messages. Importantly, a lack of visible injury does not prevent prosecution. Medical experts recognise that strangulation can cause internal injury without external marks, and courts accept that delayed symptoms are common.

National Criminal Lawyers regularly advises clients accused of choking that early legal advice is critical, particularly before participating in police interviews. Statements made without understanding how consent is assessed in law often form the backbone of the prosecution case.

The broader consequences beyond the criminal charge

A choking allegation almost invariably triggers an Apprehended Violence Order and can have immediate consequences for bail, employment and parenting arrangements. Family courts treat choking allegations as high-risk indicators, meaning that even unresolved charges can severely restrict contact with children.

For defendants, this makes early, strategic defence essential. National Criminal Lawyers has extensive experience defending choking allegations and managing the intersection between criminal proceedings, AVOs and family law disputes across NSW.

If you are under investigation or have been charged with a choking or strangulation offence, do not assume consent will protect you. The law is far stricter than most people realise. Speaking to experienced defence lawyers at National Criminal Lawyers, who understand how NSW courts approach choking allegations and sentencing, can make a decisive difference to the outcome of your case.
