Drafting a Pre-Action Protocol Letter with AI Support – Applying lawful pressure before Judicial Review proceedings
Judicial Review & AI – Part 5
Introduction: most Judicial Review cases should never be issued
This may sound counterintuitive, but it is true:
A well-drafted Pre-Action Protocol letter is often more powerful than a Judicial Review claim itself.
For litigants in person, the Pre-Action Protocol (PAP) stage is frequently misunderstood. Some see it as a formality. Others treat it as an emotional complaint.
Both approaches are mistakes.
In Judicial Review, the PAP letter is:
- a legal warning shot,
- a compliance test,
- and a credibility filter.
This article explains:
- what the Pre-Action Protocol is for,
- what the court expects from it,
- how AI can assist without undermining trust,
- and how to draft a PAP letter that actually changes behaviour.
The legal status of the Pre-Action Protocol in Judicial Review
Judicial Review claims are governed by CPR Part 54 and the Judicial Review Pre-Action Protocol.
Compliance is not optional.
Before issuing proceedings, a claimant is expected to:
- identify the decision or failure challenged,
- set out the legal basis of the claim,
- state the remedy sought,
- give the proposed defendant a reasonable opportunity to respond.
Failure to comply can result in:
- refusal of permission,
- adverse costs consequences,
- or the court questioning the claimant’s credibility.
For litigants in person, courts will allow some latitude — but not a complete absence of discipline.
What the PAP stage is actually testing
The PAP stage tests four things:
- Clarity
Can you identify the public-law issue precisely? - Legality
Are you challenging lawfulness, not outcomes? - Proportionality
Are you seeking a realistic remedy? - Seriousness
Do you understand the gravity of Judicial Review?
AI can help with all four — if used properly.
What a Judicial Review PAP letter is not
A PAP letter is not:
- a complaint,
- a witness statement,
- a narrative of injustice,
- a threat-filled ultimatum,
- a re-argument of the merits.
Letters that read like grievances are often ignored — or responded to defensively.
Judicial Review requires cool precision.
The anatomy of an effective JR Pre-Action Protocol letter
A proper PAP letter has a predictable structure. Courts expect it.
1. Identification of the claimant and proposed defendant
This must be precise.
The letter should clearly identify:
- who is bringing the claim,
- which public body is responsible,
- whether the issue lies with:
- a court,
- court administration,
- or systems operating under HMCTS.
AI can help ensure consistency — but you must choose the correct defendant.
2. The decision or failure being challenged
This is the most important section.
You must state:
- whether you are challenging:
- a decision,
- a refusal,
- or a failure to act,
- the date (or period) of that decision or failure,
- how it arose procedurally.
Vague statements like “my appeal has been ignored” are not sufficient.
AI is useful here to:
- extract precise dates,
- strip out emotive language,
- enforce specificity.
3. The factual background (short and neutral)
This section should:
- summarise the relevant chronology,
- refer to documents,
- avoid argument.
It is not the place for case law or submissions.
AI can help condense longer timelines into a tight factual summary — but it must be reviewed carefully for accuracy.
4. The legal basis of the claim
This is where discipline matters.
You must identify:
- the public-law ground relied upon:
- illegality,
- procedural unfairness,
- irrationality,
- and the duty said to have been breached.
You do not need to cite every case.
Over-citation is often counterproductive.
AI can help:
- ensure the correct ground is identified,
- prevent drift into merits-based argument,
- maintain a judicial tone.
5. The remedy sought
This must be realistic and lawful.
Common remedies include:
- determination of an appeal,
- reconsideration in accordance with law,
- provision of reasons,
- ending an unlawful delay.
You are not asking the court to decide the underlying case.
AI can help test whether the remedy aligns with Judicial Review principles.
6. Timeframe for response
The Protocol suggests 14 days in most cases.
Shorter periods may be justified where:
- delay is ongoing,
- rights are being prejudiced.
AI can help flag proportionality risks here.
7. Warning of intended proceedings (without aggression)
The letter should state calmly that:
- Judicial Review proceedings will be issued if the issue is not resolved,
- subject to the response received.
Threatening language weakens credibility.
Tone: why neutrality wins
Judicial Review correspondence is often read by:
- government lawyers,
- legal advisers,
- senior officials.
They are trained to assess risk.
A neutral, legally framed PAP letter signals:
- seriousness,
- competence,
- procedural awareness.
AI can help remove:
- emotional phrasing,
- accusatory language,
- rhetorical flourishes.
This is one of its greatest strengths.
Common PAP mistakes litigants in person make
Judicial Review PAP letters often fail because they:
- argue the merits,
- accuse judges of bias,
- demand apologies or compensation,
- include excessive attachments,
- misstate the legal basis,
- threaten media exposure.
AI can help identify and strip these out — if you let it.
How AI should be used in PAP drafting (properly)
AI should be used to:
- structure the letter,
- ensure completeness,
- check tone consistency,
- cross-reference facts to evidence,
- flag missing elements.
AI should not:
- invent legal duties,
- escalate tone,
- add speculative arguments,
- generate case law without verification.
The final letter must always be human-approved.
What happens after the PAP letter is sent
Three things usually happen:
- The issue is resolved
The appeal is listed, reasons are given, or delay ends. - A reasoned refusal is issued
This clarifies whether JR is viable. - No adequate response
This strengthens the JR claim.
AI can assist in analysing the response — but it cannot decide next steps for you.
Why courts care about PAP compliance
At the permission stage, judges often ask:
- Was the issue raised properly?
- Was the public body given a chance to respond?
- Was litigation proportionate?
A good PAP letter answers these questions before they are asked.
A poor one raises doubts immediately.
Key Takeaways (for litigants in person)
- The Pre-Action Protocol stage is substantive, not procedural.
- Most JR cases should resolve here.
- A PAP letter must challenge lawfulness, not fairness.
- Tone matters as much as content.
- AI is most valuable for:
- structure,
- neutrality,
- consistency,
- error prevention.
- A strong PAP letter often determines the outcome before court.
If you cannot clearly articulate the public-law failure in a PAP letter, Judicial Review is unlikely to succeed.
Preparing for the next step
If the PAP stage does not resolve matters, the next step is:
- issuing Judicial Review proceedings,
- drafting Statement of Facts and Grounds,
- and preparing for the permission stage.
That process is unforgiving.
AI can help — but only if everything so far has been done properly.
Call to Action
If you are considering Judicial Review and want help:
- drafting a compliant Pre-Action Protocol letter,
- ensuring your case is framed correctly,
- or understanding whether proceedings are proportionate,
You may wish to seek structured support before issuing any claim.
