Citing appeal decisions: weight, relevance and referencing
An appeal decision is indicative of how inspectors have approached an issue, not binding precedent. Citing one as though it binds is the quickest way to lose its value.
A Planning Inspectorate appeal decision is a material consideration. It is not binding precedent, and no inspector is obliged to follow another inspector's conclusion on a different site. What a decision can do is show how the policy test has been applied to comparable facts, and consistency in decision-making is itself something decision-makers are expected to have regard to. Those two propositions sit behind every good citation and every weak one.
The weak version looks like a list of reference numbers with a sentence asserting that the appeals were allowed. It persuades nobody.
Why appeal decisions are indicative rather than binding
Each application is determined on its own facts against the development plan in force for that area, under section 38(6) of the Planning and Compulsory Purchase Act 2004. An appeal decision about a site in another authority applies a different development plan, so its conclusions on policy compliance cannot transfer directly.
What does transfer is reasoning about matters of general application: how a national policy test works, what evidence an inspector found adequate, how a particular technical standard was treated, what weight was given to a type of harm.
The courts have accepted that like cases should be decided alike and that an inspector departing from a previous decision on materially similar facts should explain why. That is a duty to give reasons rather than a rule of precedent, and the distinction matters to how you frame the point.
High Court and appellate judgments are different. Those are binding authority on points of law, and they should be cited as such rather than mixed in with inspector decisions.
Finding decisions and checking they still stand
The Planning Inspectorate's appeals casework portal holds decisions and the associated documents, and it is the primary source. Search by authority, by development type and by date.
Three checks before you rely on anything.
First, check the date against the policy position. A decision turning on the absence of a five year housing land supply is of limited help where the authority can now demonstrate one, and a decision applying a superseded edition of the Framework needs its reasoning separated from its policy references.
Second, check whether the decision was challenged. A decision quashed under section 288 of the Town and Country Planning Act 1990 no longer stands, and citing one is the kind of error that costs credibility for the rest of the submission.
Third, read the whole decision rather than the summary. Inspectors frequently allow an appeal on one issue while making findings against the appellant on another, and quoting the allowed outcome without the unfavourable finding invites the council to supply it.
Referencing a decision properly
Give the appeal reference, the site address, the date of the decision and the paragraph number you rely on. The reference is the identifier the case officer will use to find it, and a citation without one is an assertion.
Attach the decision letter as an appendix rather than linking to it, because links in planning documents break and officers work from PDFs.
Then quote accurately. Short quotations of the relevant finding, with the paragraph number, are far more effective than a paraphrase, and a paraphrase that overstates the finding will be checked.
Set out the facts of the appeal site alongside the facts of your site, so the reader can see the comparison rather than being asked to accept it. A short table does this well:
| Point of comparison | Appeal site | Application site |
|---|---|---|
| Development proposed | State it | State it |
| Relevant designation | State it | State it |
| Policy framework applied | State it | State it |
| Issue the decision turned on | State it | State it |
Leave the differences in. An honest comparison that acknowledges two points of difference and explains why they do not matter reads far better than one that pretends the sites are identical.
Distinguishing an unhelpful decision
The council will cite decisions too, and the technique for dealing with them is distinction rather than dismissal.
Look for differences in the development plan applied, the scale or nature of the proposal, the evidence that was before the inspector, the designation affecting the site, and the date relative to a policy change. Any one of these can be enough.
The strongest distinction is usually evidential. Where an appeal was dismissed because the appellant produced no survey, and you have produced one, the decision supports your case rather than undermining it. Say so directly.
Be careful with appeals dismissed on multiple grounds. Addressing one ground and ignoring the others is transparent, and an experienced officer will note it.
Where a decision really is against you on comparable facts, the better approach is to acknowledge it and explain what is different about the proposal now, as discussed in the piece on reading a refusal notice and turning it into a plan.
Consistency as a material consideration
Consistency works best when the decisions are local. A decision by the same authority, or an appeal decision on a site in the same authority applying the same local plan policies, carries more weight than a decision from the other end of the country.
Decisions on adjoining or nearby sites are the strongest of all, particularly where the same officer, the same policy and the same constraint were in play.
Where an authority has itself granted permission for a comparable scheme, that is often more useful than an appeal decision, because it shows the authority's own application of its own policy. Officer reports are public and can be cited in the same way.
Build the argument as consistency rather than entitlement. The point is that the authority should reach the same conclusion on the same policy and similar facts, or explain the difference.
Volume against relevance
Three well-analysed decisions beat fifteen listed ones. A long schedule of references signals that none of them is strong enough to stand on its own.
Select on relevance to the specific issue in dispute. If the refusal reason is about highway safety at a substandard access, cite decisions about substandard accesses, not decisions that happen to be in the same village.
Put the analysis in the main text and the decision letters in an appendix. An officer with 40 applications on their list will read two pages of argument and will not read 200 pages of appendices.
A Planning Statement is the right place for this analysis on an application, and the statement of case or appeal statement on an appeal. Keep it in one section rather than scattering references through the document.
Mistakes that undermine a citation
- Citing a decision without the reference number or date.
- Quoting a conclusion out of context when the same decision contains an adverse finding.
- Relying on a decision applying a superseded policy without addressing the change.
- Treating an inspector's decision as if it bound the authority.
- Citing a quashed decision.
- Listing decisions without analysing the facts.
- Overstating the comparability of the sites.
One honest point to accept: the weight an inspector gives to another decision is a matter of judgement, and two inspectors can reasonably reach different conclusions on similar facts. Citing decisions improves a case; it does not decide one. The companion piece on what objectors can do once a planning appeal starts covers the other side of the same process.

Frequently asked questions
Are appeal decisions binding on a council?
No. Each application is determined on its own facts against the development plan for that area under section 38(6) of the 2004 Act. An appeal decision is a material consideration that shows how an inspector approached a comparable issue. Where facts are materially similar, a decision-maker departing from the earlier conclusion should explain why.
Where do I find appeal decisions?
The Planning Inspectorate's appeals casework portal is the primary source and holds decision letters and associated documents, searchable by authority, development type and date. Always check whether a decision has been challenged, because a decision quashed under section 288 of the Town and Country Planning Act 1990 no longer stands.
How should a decision be referenced?
Give the appeal reference number, the site address, the decision date and the paragraph you rely on, and attach the decision letter as an appendix rather than a link. Quote the relevant finding accurately and short, and set out the facts of both sites so the comparison can be checked rather than assumed.
How many decisions should I cite?
Two or three analysed properly, rather than a long schedule. A list of fifteen references signals that none is strong on its own. Select on relevance to the specific issue in dispute, put the analysis in the main text, and keep the decision letters in an appendix that nobody has to read to follow the argument.
What if the council cites a decision against me?
Distinguish it rather than dismiss it. Look at the development plan applied, the scale and nature of the proposal, the evidence before the inspector, the designations and the date relative to any policy change. The strongest distinction is usually evidential, for example where an appeal failed for lack of a survey you have now produced.
