Yes, I'm not sure of the exact mechanism, SacreBlue. Have only the vaguest idea of 'super complaints'.
'The super-complaint, a mechanism that allows organisations to highlight harmful patterns or trends in policing, is being brought 10 years on from a change to the law that made stalking a specific offence.'
This might explain it a bit more:
www.gov.uk/government/collections/police-super-complaints
There have been a few there relevant to women:
Police super-complaints: police response to BAME victims of sexual abuse
5 March 2021
Police super-complaints: force response to police perpetrated domestic abuse
23 November 2022
Police super-complaints: police response to victims of modern slavery
4 April 2022
Police super-complaints: police use of protective measures in cases of violence against women and girls
7 June 2022
Only designated bodies can bring a 'super complaint', these are they:
Bodies designated on 25 June 2018
Action on Elder Abuse
Advocacy After Fatal Domestic Abuse
Centre for Women’s Justice
Children’s Commissioner for England
Criminal Justice Alliance
Faith Matters
Galop
Hestia
Liberty
Missing People
Pathway Project
Southall Black Sisters
Suzy Lamplugh Trust
Tees Valley Inclusion Project
Welsh Women’s Aid
Women’s Aid Federation of England
So I guess one could ask one of the relevant bodies to raise a super complaint?
