Fabricated references and how to spot them in a draft

7 min readBy PlanScope Editorial Team

A fabricated citation is well-formed and wrong. The checks for appeal references, neutral citations, statutory instruments and standards, and the routine that catches them before submission.

A fabricated reference is not a typing error. It is a well-formed citation for something that does not exist: an appeal reference in the correct format for a decision never issued, a neutral citation for a judgment never handed down, a British Standard number with a plausible year. That is what makes them dangerous in a planning document. They look right, they pass a quick read, and they fail the moment a case officer or an opponent looks them up.

Any drafting process can produce them, including a junior fee-earner working from an old precedent file. Automated drafting produces them more often, because a citation has a strong pattern and a pattern is easy to complete.

Why fabricated references appear

Generated text is built on what usually follows what. An appeal reference has a rigid shape, so the shape is easy to reproduce. The case number inside it carries no meaning the generator can check.

The same applies to a law report citation, a policy paragraph number and a standard's year. All of them are formats, and a format can be filled with confident-looking nonsense. PlanScope's drafting inserts a marker where site facts are missing rather than guessing them, which is the right instinct applied to facts. References need the same treatment, and it falls to whoever reviews the draft to apply it.

There is a second source that gets less attention: references that were once correct. A paragraph number from an earlier edition of the Framework, a standard superseded by an amendment, a statutory instrument since revoked. Nobody invented those. They are simply out of date, and they undermine a submission in the same way.

Checking an appeal reference properly

Appeal references follow a structure: the prefix, a code for the local planning authority, a letter for the appeal type, the year and the case number. The type letter tells you what kind of appeal it was, with W for most section 78 appeals, D for householder appeals and C for enforcement appeals.

Check three things, in this order.

  1. That the reference resolves to a real decision on the Planning Inspectorate's casework portal
  2. That the authority code in the reference matches the authority you have named
  3. That the decision says what you have said it says, including whether the appeal was allowed or dismissed

The third check catches the more embarrassing error. A reference that exists, attached to a summary of a different case, is worse than a reference that does not exist at all, because it reads as misrepresentation rather than carelessness.

Also read the decision rather than a summary of it. Inspectors' conclusions are fact-specific, and a decision cited as authority for a general proposition usually turns out to have turned on something local.

Verifying a court citation

Neutral citations identify the court, the year and the sequence number, and they are searchable. A planning judgment of the Administrative Court appears as a year in square brackets followed by EWHC, a number and (Admin). The Court of Appeal uses EWCA Civ, and the Supreme Court uses UKSC.

Element What to check Where
Neutral citation That it resolves to a judgment Find Case Law, the National Archives service
Party names That they match the citation The judgment itself
Court and year That the combination is possible The citation format
The proposition That the paragraph you rely on says it The judgment text, by paragraph
Status Whether it was appealed or distinguished Later judgments citing it

Cite the paragraph of the judgment, not the case as a whole. An opponent who has to read 90 paragraphs to find your point will read them, and will tell the inspector if the point is not there.

Statutory instrument titles and years

Cite the full title with its year, and check the instrument still does what you say. Three failure modes recur: the wrong year, a title that mixes two instruments, and a provision that was never brought into force.

The date a provision came into force deserves particular care. A power in an Act is not a rule until it is brought into force, and a proposal announced in a consultation is not a power at all. Where you rely on something recent, state the position as at a date, and say if it is not yet in force.

Check amendments too. The General Permitted Development Order 2015 has been amended many times, and a class described in its original form may have moved on. Read the current consolidated text rather than a commentary about it.

British Standards and their revision dates

A standard citation has three parts that can each be wrong: the number, the year and any amendment suffix. BS 4142:2014+A1:2019 is a different document from BS 4142:2014, and an assessment referring to the wrong one invites a consultee comment.

Check whether the standard has been superseded, whether it was withdrawn without replacement, and whether the section number you cite exists in the edition you name. Quote sparingly and attribute, because standards are copyright works and reproducing substantial parts of them is not something a planning submission needs.

A verification routine before submission

Make this a discrete task with a named owner, done after drafting and before the pack is assembled. Our note on building an internal review checklist covers the wider version of this, and factual errors to look for in a drafted document deals with the site-specific side.

The reference-specific routine:

  • List every citation in the document in a single table before you check any of them
  • Resolve each one to its primary source, and record the date you checked it
  • For each appeal or judgment, note the outcome and the paragraph relied on
  • Confirm the edition of any policy document cited, and state that edition in the text
  • Delete any citation you cannot resolve, and rewrite the sentence so the argument stands without it
  • Flag anything that depends on a provision not yet in force

That last deletion rule is the one people resist, because the citation was doing work. Do it anyway. An argument that needs an unverifiable reference was not a strong argument.

One specific trap for anyone using drafted output: national policy references in drafted text may be written against an older edition of the Framework. The Framework re-issued on 17 August 2026 is organised by policy codes such as GB6 and DP2 rather than the paragraph numbers used in the December 2023 and December 2024 editions. Never carry a paragraph number straight from drafted output into a submission. Check it against the current published Framework and cite the edition.

What to do if one reaches a council

Deal with it quickly and in writing. Send the case officer a short note identifying the incorrect reference, giving the correct one if there is one, and confirming whether the argument in the document survives the correction.

Do not wait for the officer's report. If the reference has already been repeated in a committee report or a consultee response, the correction needs to reach the file before the decision, and the sooner it does, the less it looks like something you hoped nobody would notice. Our note on when a council asks who wrote your report covers the related conversation about authorship.

There is also a professional dimension. Members of the RTPI and other institutes are subject to codes requiring honesty and competence, and a submitted document with invented authority is a conduct question as much as a drafting one.

As an illustrative example, a draft green belt statement cites an appeal decision in support of a very special circumstances argument. The reference format is correct, the authority code matches the borough, but the portal returns nothing. The reviewer deletes the sentence, replaces it with the policy test itself and a site-specific justification, and the statement gets stronger. That is the usual outcome.

Reviewers who can check and sign off drafted reports can be found through the professional directory, and PlanScope pricing for drafts, including one free report, is set out on the pricing page.

Frequently asked questions

How do I check an appeal reference is real?

Resolve it on the Planning Inspectorate's casework portal, confirm the authority code in the reference matches the council you have named, and read the decision to check it says what you claim. A reference that exists but is attached to a different case reads as misrepresentation rather than carelessness, so the third check matters most.

Where can I verify a planning court citation?

Use Find Case Law, the National Archives service, and check the neutral citation resolves to a judgment with the party names you have given. Then cite the paragraph you rely on rather than the case generally, and check whether the judgment was appealed or distinguished in later cases before presenting it as settled.

Why do out-of-date references cause the same problem?

Because the submission is wrong either way. A paragraph number from a superseded edition of the Framework, a withdrawn British Standard or a revoked statutory instrument all undermine a document even though nobody invented them. State the edition of every policy document you cite and check amendment suffixes on standards.

Can I cite a policy that has been consulted on but not made?

You can refer to it, but not as policy. Say plainly that it is at consultation stage or not yet in force, give the date the position is stated as at, and do not build an argument that only works if the change takes effect. Decision makers give little weight to something that is not yet in force.

What should I do if a wrong reference is already with the council?

Write to the case officer straight away identifying the error, giving the correct reference where one exists, and confirming whether the argument survives the correction. Do it before the officer's report is written. If the reference has been repeated in a consultee response, the correction needs to reach the file before determination.
