How should public bodies, and particularly the police, record the sex of individuals charged or convicted of rape?
This once uncontroversial question is now attracting scrutiny at Holyrood, by oversight bodies and in the media. This has revealed that across the Scottish justice system, policy provides for the production of official data based on individuals’ self-identified gender rather than their biological sex. Although defended as necessary to align with human rights and equality concerns, this approach in fact contradicts international human rights requirements.
Recording sex and gender: approach of Scottish justice actors
A 2021 petition lodged with Holyrood’s Citizen Participation and Public Petitions Committee exhorted ‘Police Scotland, the Crown Office and the Scottish Court Service to accurately record the sex of people charged or convicted of rape or attempted rape’ (PE 1876). As defined in Scotland (Sexual Offences (Scotland) Act 2009, section 1), rape may be perpetrated by a biological man or biological woman, victims may be biologically male or female, and women may also be liable on an ‘art and part’ basis.
Accurately tracking incidence and trends in sexual crime, including with reference to specific individual characteristics, requires the collection of data on both sex and gender. However, in its evidence to the Petitions Committee, Police Scotland disclosed that on all systems such as crime management and custody databases, it uses sex and gender interchangeably – not just for rape, but for all offences, whether or not of a sexual nature. Further, the force does not ‘routinely ask the gender or sex of people with whom they interact’ but bases the sex/gender identification of individuals on how they self-declare, or ‘…on how the person presents to officers at the time of engagement’, unless doing otherwise is ‘evidentially critical’. ‘No evidence or certification as proof of biological sex or gender identity’ is required unless this is ‘pertinent’ to an investigation.
According to Police Scotland, this approach reflects ‘legislative compliance, operational need and the values of respect, integrity, fairness and human rights’ while also ‘promoting a strong sense of belonging’.
The Scottish Courts and Tribunals Service, and the Crown Office and Procurator Fiscal Service mirror Police Scotland’s approach. This appears consistent with Scottish Government Guidance for public bodies on collecting sex and gender data for operational, statistical and research purposes, published in 2021. Policy and decision-making on ‘operational data collection decisions’, under the Guidance, is deferred to individual public authorities. Only in rare cases, the Guidance provides, will it ‘be necessary and proportionate’ for such bodies to depart from self-identified gender ‘to require a person to answer a question on their biological sex’. Though the investigation of serious sexual offences is in this regard cited as an example, on the other hand, the Guidance warns, gathering data on sex may otherwise ‘be an unjustifiable breach of privacy’.
Sex-disaggregated data and violence against women: international standards
Are justice system actors entitled to take this approach when recording crime? At least in relation to crimes against women, it would appear not.
The UK is a party to various treaties that prohibit violence against women, including rape and sexual assault. These include the United Nations’ women’s rights convention (CEDAW, Arts 1-3, 5(a)) and the Council of Europe’s Convention on preventing and combating violence against women and domestic violence (Istanbul Convention). The United Kingdom ratified the latter in 2022.
As part of a package of preventive measures, Article 11 of the Istanbul Convention requires states to collect data on all forms of violence against women. Although, according to the Convention’s accompanying Explanatory Report, the drafters ‘left the choice of data categories used’ to states parties, ‘as a minimum requirement, recorded data on victim and perpetrator should be disaggregated by sex, age, type of violence as well as the relationship of the perpetrator to the victim, geographical location and any other factors deemed relevant by the state in question’ (para.76).
Highlighting that ‘The usefulness and relevance’ of data on violence against women ‘depend above all’ on their quality‘, the Explanatory Report adds, ‘public authorities such as the judiciary, the police and social welfare services will need to set-up data systems …that go beyond the internal recording of the needs of the agency’ (para. 76). While the privacy of both victims and perpetrators should be safeguarded, it is clear that no privacy-based obstacle to collecting sex-disaggregated data is foreseen (para.80; see also Art. 65 Istanbul Convention).
Additional guidance provided by the Council of Europe identifies sex-disaggregation of data collected by law enforcement as ‘compulsory’ (p.36). Likewise, European Union-level recommendations on rape statistics in particular direct states to ‘include specific breakdowns essential for identifying rape, including data on the sex and age of the victim and perpetrator and the victim–perpetrator relationship as a minimum’.
Under the UN women’s convention, states have been recommended, ‘To develop judiciary databases on complaints, investigations, prosecutions, and protection orders related to [gender-based violence against women] disaggregated by age, sex, disability, crime, punishment, redress and relationship between the perpetrator and the victim.’ The UN Statistical Division (UN Guidelines for Producing Statistics on Violence against Women— Statistical Surveys, pp.26-27) also presumes the collection of data on perpetrators and victims by sex.
Conclusion
Police Scotland has adopted admirable commitments and policies on violence against women. How the force’s current position on data collection was arrived at, given this, is perplexing.
In any event, it is incorrect that legal compliance and ‘human rights’ demand gender self-identification in the generation of official data on rape and forms of violence against women, to the exclusion of data on sex. On the contrary, they preclude it.
