A new offence of controlling or coercive behaviour in intimate or family relationships has recently come into force in England. The parliament of Scotland is contemplating introducing a related offence. The offence is distinctive because it criminalises conduct – controlling and coercive behaviour – which has specified negative behavioural and psychological consequences without necessarily requiring that a victim sustain physical injury or fear death or serious harm. This significant extension of the criminal law supplements anti-stalking legislation and has been justified on the basis that it addresses a core feature of abusive relationships, is essential to protect the human rights of victims of domestic abuse, and has community support. In the context of the ongoing debate about how best to tackle the problem of domestic abuse in Australia, this development provides an innovative – albeit still untested – model and should be closely examined.
