The potential efficacy of a new offence of coercive control will be determined by the constellation of factors that surround its implementation. Drawing on experiences with s 76 of the Serious Crime Act 2015 (E&W) in England and Wales and the Domestic Abuse (Scotland) Act 2018 (Scot), these factors are identified as: a coherent national strategic framework; an articulation of the current dilemma posed to the justice system by policing domestic violence; centralised coordination by justice professionals; activist pressure from advocacy organisations such as Women's Aid; and exhibitions of political will.
