Request an anti-social behaviour case review

Victims of anti-social behaviour can ask us, the police, social housing providers and other partners, to carry out an anti-social behaviour case review. This review process was formerly known as the community trigger. 

Before you start

Making a request for a multi-agency anti-social behaviour case review is a way to escalate your existing complaints if you feel they need to be further investigated. It is not the same as making a complaint about anti-social behaviour. Find out how to make a complaint about anti-social behaviour.

  • We cannot carry out a case review for anti-social behaviour if it is already being investigated by another agency, for example, if there is an ongoing investigation by Merseyside Police.
  • We cannot reinvestigate anti-social behaviour that has already been reviewed by us when there has been no change in the circumstances.

Who can ask for a case review?

For a request for a case review to be considered, you will already need to have complained about the anti-social behaviour. The details of the steps you must have taken are set out below.

  • For a hate crime or incident – you must already have complained to Liverpool City Council, Merseyside Police, or a registered social housing provider at least once in the past six months.
  • For other types of anti-social behaviour – you must already have complained to Liverpool City Council, Merseyside Police, or a registered social housing provider at least three times about separate instances of the antisocial behaviour in the past six months. Alternatively, five people in the local community must have complained about similar incidents in the last six months.

Anyone can make a request for a case review or ask someone to do so on of their behalf. For instance, you may want to ask your local councillor or local MP to make the request for you.

How to make a request

We have two separate request forms. One for an individual or their representative to use, and one for a group of five or more people. Please select the correct form that applies to you.

What happens next?

When we receive your request, an initial assessment will be carried out within 10 working days. Our team will look at your request and consider the:

  • frequency of complaints
  • effectiveness of the response
  • potential harm to the victim or victims making the complaint

If your request does not meet the case review threshold, you will be informed by email within 10 working days of you submitting the form.

If it does meet the threshold, a case review meeting will be held within a further 20 working days. We will email you with the case review findings 10 days after the review was held.
