From Pre-Action Protocol to Permission – Structuring Judicial Review grounds with AI — and avoiding merits traps

Judicial Review & AI – Part 6

Introduction: permission is the real battlefield

Most Judicial Review claims never reach a full hearing.

They fail — quietly and decisively — at the permission stage.

For litigants in person, this can feel bewildering. Everything may feel unfair. The process may have stalled. Appeals may have been ignored. And yet the court refuses permission in a few short paragraphs.

The reason is usually not lack of injustice.

It is poor framing.

This article explains:

  • what the permission stage is actually testing,
  • how Judicial Review grounds must be structured,
  • why merits-based arguments are fatal,
  • and how AI can help enforce discipline, not inflate claims.

What the permission stage is for (in reality)

Under CPR Part 54, the Administrative Court must decide whether a claim is:

  1. Arguable, and
  2. Suitable for Judicial Review.

This is not a mini-trial.
It is a filtering exercise.

Judges are asking:

  • Is this a genuine public-law issue?
  • Is there an alternative remedy?
  • Is the claim focused and lawful?
  • Is it proportionate for the High Court?

If the answer to any of these is “no”, permission is refused.

Why litigants in person struggle most at this stage

Litigants in person often:

  • understand the facts deeply,
  • experience the injustice personally,
  • know exactly what feels wrong.

But Judicial Review does not operate on feelings.

It operates on:

  • duties,
  • legality,
  • jurisdiction,
  • restraint.

The hardest shift is moving from:

“This decision was wrong”
to
“This decision-making process was unlawful.”

AI can help enforce that shift — if used correctly.

The structure of Judicial Review grounds (what the court expects)

Judicial Review grounds are not free-form.

They are expected to follow a disciplined structure:

  1. The decision (or failure) challenged
  2. The legal duty or power
  3. The public-law ground
  4. How the duty was breached
  5. Why Judicial Review is appropriate
  6. The remedy sought

If any of these are missing or muddled, permission is at risk.

Ground 1: identifying the correct target

Your grounds must clearly identify:

  • what is being challenged,
  • when it occurred,
  • who is responsible.

This may be:

  • a refusal,
  • a failure to determine,
  • a procedural decision,
  • or a constructive refusal.

Vague formulations (“the court has ignored me”) almost always fail.

AI can assist by:

  • enforcing specificity,
  • flagging ambiguity,
  • aligning grounds with your chronology.

Ground 2: identifying the legal duty

This is where many claims collapse.

Judicial Review requires:

  • a legal duty,
  • not just a power,
  • and not just an expectation.

The question is:

Was the public body required by law to act — and did it fail to do so lawfully?

Without a duty, there is no unlawfulness.

AI can help:

  • check whether you are assuming a duty,
  • flag where a duty needs to be evidenced,
  • prevent overstatement.

But you must verify the law.

Ground 3: choosing the correct public-law ground

Most JR claims rely on one (sometimes two) grounds:

Illegality

The decision-maker:

  • misunderstood the law,
  • failed to exercise a required power,
  • or acted outside jurisdiction.

Procedural unfairness

The process was unfair because:

  • no reasons were given where required,
  • no opportunity to be heard was provided,
  • mandatory procedure was not followed.

Irrationality

A very high threshold — rarely appropriate for litigants in person.

AI can help prevent the common mistake of:

  • pleading all grounds “just in case”.

Courts view that as lack of focus.

The single biggest mistake: merits drift

Merits drift occurs when:

  • arguments about fairness,
  • disagreement with reasoning,
  • or dissatisfaction with outcomes

creep into what should be a process challenge.

Examples of merits drift:

  • arguing evidence should have been weighed differently,
  • asserting bias without procedural basis,
  • challenging findings of fact.

These are appeal issues — not Judicial Review issues.

AI is particularly useful here:

  • it can flag evaluative language,
  • identify opinion-based phrasing,
  • and force re-framing into procedural terms.

Keeping law and fact separate (critical discipline)

Judicial Review requires:

  • facts to be stated neutrally,
  • law to be applied to those facts,
  • not blended together.

A common error is embedding argument into factual narrative.

AI can help by:

  • separating factual chronology from legal analysis,
  • highlighting where language crosses the line,
  • enforcing neutral drafting.

This separation builds judicial trust.

Alternative remedy: the silent killer of JR claims

Even where unlawfulness exists, Judicial Review may still fail if:

  • an appeal route exists,
  • or another adequate remedy is available.

Courts are firm on this.

You must:

  • identify the appeal route,
  • explain whether it exists in reality,
  • and justify why JR is still appropriate.

This is where litigants in person often underestimate the burden.

AI can help:

  • structure this justification,
  • but cannot invent a lack of remedy where one exists.

Remedy: what you can (and cannot) ask for

Judicial Review remedies are limited.

You may ask for:

  • a decision to be quashed,
  • a matter to be reconsidered lawfully,
  • a duty to be performed.

You cannot ask the High Court to:

  • decide the underlying appeal,
  • substitute its own view of the facts,
  • grant compensation (save in rare cases).

AI can help test whether the remedy sought aligns with JR principles.

How AI should be used at the permission stage

AI is best used as a quality-control tool, not a generator.

Proper uses include:

  • checking internal consistency,
  • identifying merits drift,
  • ensuring each ground maps to evidence,
  • testing whether each ground answers the “so what?” question.

AI should not:

  • expand arguments,
  • multiply grounds,
  • add speculative claims,
  • generate case law without verification.

Permission-stage discipline is about less, not more.

The court’s perspective: what judges scan for first

Judges reviewing permission applications often:

  • skim first,
  • assess focus,
  • test plausibility quickly.

They are alert to:

  • scattergun pleading,
  • emotional language,
  • disproportionate claims.

A tight, restrained set of grounds signals seriousness.

Key Takeaways (for litigants in person)

  • The permission stage is the real test in Judicial Review.
  • Grounds must challenge lawfulness, not outcomes.
  • Identify a legal duty — or the claim fails.
  • Merits drift is the most common fatal error.
  • AI is most useful as a:
    • discipline tool,
    • clarity enforcer,
    • consistency checker.
  • Fewer, stronger grounds beat many weak ones.

If you cannot state your grounds in calm, procedural language, Judicial Review is unlikely to succeed.

Preparing for the final stages

If permission is granted, the case moves into:

  • full pleadings,
  • possible disclosure,
  • and substantive hearing.

But many litigants will face:

  • permission refusal,
  • or a conditional grant.

The final article in this series addresses that moment — and how to respond rationally.

Call to Action

If you are:

  • preparing Judicial Review grounds,
  • unsure whether your case has drifted into merits,
  • or worried about permission-stage refusal,

You may wish to seek structured support before issuing proceedings.

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:

  1. Clarity
    Can you identify the public-law issue precisely?
  2. Legality
    Are you challenging lawfulness, not outcomes?
  3. Proportionality
    Are you seeking a realistic remedy?
  4. 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:

  1. The issue is resolved
    The appeal is listed, reasons are given, or delay ends.
  2. A reasoned refusal is issued
    This clarifies whether JR is viable.
  3. 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.
