Turning Prison Decisions Into Legal Opportunities
When someone is in a London prison, decisions by staff can change daily life in a big way. Segregation under Rule 45, closed visits and adjudications can all affect how a sentence is served and how quickly someone can progress. For many people in places like Belmarsh, Pentonville, Wandsworth, or Wormwood Scrubs, these decisions can feel final and impossible to challenge.
They are not. Prison law gives prisoners and their families a way to challenge decisions that are unlawful or plainly unfair. Judicial review is one of the main court-based tools for doing this. It is powerful, but it is also fast-moving, with tight time limits and strict rules on evidence.
In this guide, we explain which prison decisions can be challenged by judicial review, how the process works step by step, what evidence matters most, and why acting quickly is so important when you are dealing with segregation, closed visits or adjudications in London prisons.
When a Prison Decision Can Be Judicially Reviewed
Not every bad or upsetting decision can go to court. Some decisions will stay within the internal complaints system or go to the Prisons and Probation Ombudsman. Judicial review is for decisions by public bodies, including HMPPS, that are alleged to be unlawful in a public law sense.
Common decisions in London prisons that may be suitable for judicial review include:
- Rule 45 segregation authorisations and reviews
- Closed or restricted visits, especially where they last for long periods
- Governor adjudications that affect days lost or privileges
- Independent Adjudicator decisions that impact release dates
- Security or categorisation decisions based on alleged risk
Some issues are usually better dealt with internally, for example:
- Routine complaints about lost property
- Minor IEP level changes that are quickly corrected
- Day-to-day regime problems where no long-term effect is shown
For judicial review, the court looks at whether the decision is:
- Illegal, for example made outside the rules or ignoring key policies
- Procedurally unfair, for example no fair hearing, bias, or no reasons given
- Irrational or clearly disproportionate, for example a punishment that goes far beyond what policy allows
In London prisons, we often see:
- Long periods in segregation without proper reviews
- Closed visits based on thin or old intelligence, with no chance to respond
- Adjudications that do not match the evidence or ignore CCTV or witness accounts
These are the kinds of situations where a public law challenge can be considered.
Challenging Segregation, Closed Visits and Adjudications
Segregation under Rule 45 is one of the most serious decisions a prison can make. It means a prisoner is held apart from others, often with very limited contact and activity. Rule 45 requires:
- Clear and recorded reasons for segregation
- Regular reviews, usually at set intervals
- Proper consideration of mental health and vulnerability
If reviews are just a tick-box exercise, if the same reasons are repeated without change, or if mental health warnings are ignored, that can open the door to a judicial review claim.
Closed or restricted visits are another key area. Visits can be limited for security reasons, for example if there are drugs or mobile phone concerns. But staff must:
- Use reliable intelligence and keep it under review
- Give as much information as safely possible about the concerns
- Consider the impact on family life, including children
Article 8 rights to family and private life are in play here. Long-term closed visits without proper evidence or review may be unlawful.
Adjudications carry their own risks. Governor hearings and Independent Adjudicator hearings are meant to be fair and based on clear rules. Problems often arise where:
- Legal representation is refused in more serious cases
- Disclosure is incomplete or late
- Witnesses or CCTV are refused without good reason
- Punishments are far harsher than policy or guidance suggests
In London prisons, situations often relate to gang-linked intelligence, drugs, phones or alleged disruptive behaviour on wings. If procedures are not followed properly, even serious allegations can be challenged.
Step-by-Step Judicial Review Process and Time Limits
Judicial review is not the first step. Before court action, there is usually a pre-action stage. This often includes:
- Using the prison complaints process (COMP1 and COMP1A)
- Sending open letters to the governor to request reasons or a review
- A formal pre-action protocol letter setting out the legal issues
Prompt contact with prison law specialists is very important at this stage. Acting while the person is still in segregation or while a visit ban is ongoing makes it easier to gather evidence and show ongoing harm.
Time limits are strict. Court proceedings must normally be issued:
- As soon as possible, and
- No later than three months from the date of the decision
Delay can be fatal to a case, even if you stay within three months. Adjudications that affect release dates, or categorisation before a parole or recategorisation review, often need especially quick action.
Issuing a claim involves:
- Taking detailed instructions, often by legal visit, video link or secure email
- Preparing grounds of claim that set out the facts and legal arguments
- Serving the papers on the prison, HMPPS and the Treasury Solicitor
- Waiting for a High Court judge to decide if permission should be granted
There is also the option of interim relief, which is an urgent request to the court to pause a decision while the case is heard. This can include:
- Asking to suspend segregation under Rule 45
- Seeking restoration of open visits or contact
- Staying adjudication punishments that affect release or category
Interim relief has a high threshold. The court will expect strong evidence, real urgency and a clear legal issue.
Evidence That Makes or Breaks a Prison Law Case
In prison law, evidence is everything. A strong judicial review claim usually combines several types of material.
Key documents can include:
- Segregation paperwork and review forms
- Security Information Reports (SIRs) where they can be disclosed
- Adjudication charge sheets and hearing notes
- COMP1 and COMP1A complaint forms and responses
- Medical records, mental health notes and ACCT documents
- Categorisation and risk assessment records
Witness evidence can also be very important:
- A detailed statement from the prisoner describing what happened
- Statements from family about visits, phone contact and impact on children
- Supportive evidence from professionals such as psychologists, probation officers, chaplains or other people who know the prisoner in a formal role
Objective material adds weight and can support or undermine what the prison says:
- CCTV and body-worn video footage
- Cell search logs and property records
- Drug test results or phone monitoring records
- Published reports by HM Inspectorate of Prisons or the Independent Monitoring Board that comment on conditions or practice in a specific prison
Presenting this evidence in a clear timeline, showing patterns and contradictions, is key. Experienced prison law solicitors know how to ask for disclosure, how to protect sensitive sources where needed, and how to argue when security or intelligence is used to limit what is shared.
Take Prompt Action to Protect Rights in Custody
Prison decisions can change quickly, but their impact can last for years, especially where segregation, visit bans or serious adjudications are involved. Strict judicial review deadlines leave little space for delay. Gathering documents while events are still recent usually produces a stronger, clearer case.
Families, support workers and charities play an important role by:
- Keeping careful notes of dates of decisions and reviews
- Saving letters, complaints and responses
- Checking whether there are new sanctions after incidents
- Asking questions when a decision feels unfair or extreme
