Criminalising Non-Fatal Strangulation in the United Kingdom: Comparative Legal Analysis and Early Evidence on Intimate Partner Homicides

This article examines how non-fatal strangulation and suffocation (NFS) conduct is criminalised across UK jurisdictions and whether the introduction of a standalone NFS offence in England and Wales is associated with changes in intimate partner homicide (IPH). Its principal contribution is comparative and legal: it shows how England and Wales, Northern Ireland, and Scotland differ in defining, charging, and proving NFS-type conduct. The analysis argues that standalone offences give NFS specific visibility as a high-risk form of coercive violence, reduce reliance on visible injury, and create clearer evidential, charging, and recording pathways. By contrast, Scotland’s reliance on general assault, attempted murder, sexual offences where relevant, and course-of-behaviour domestic abuse legislation offers serious legal responses but less offence-specific labelling of NFS as a distinct risk marker. Exploratory difference-in-differences analysis suggests declines in female-victim IPH counts in England and Wales, but causal inference is limited by pre-trends, rare-event volatility, and short follow-up.
