Partial refusals and appealing one element of a scheme

A planning appeal is against the decision, not against a reason for refusal, so the starting point is that you cannot appeal part of a refusal and leave the rest alone. What you can sometimes do is appeal a proposal that was itself severable, or narrow the issues so far that the inspector's attention falls on one point. Those are different things, and confusing them is how appellants lose control of a case.

The question is whether the proposal can be split, not whether the reasons can be counted.

Whether a decision can be split at all

A refusal notice refuses the application. Where the application sought permission for one development, the appeal puts that development before the inspector, who redetermines it on the merits and can uphold or dismiss it on any ground, including ones the authority never raised.

That has two consequences people underestimate. An inspector can dismiss on a matter the council accepted, because the redetermination is complete rather than confined to the disputed points. And an inspector can grant permission notwithstanding a reason for refusal you never contested, if the evidence supports it.

So there is no mechanism that lets you appeal reason three and accept reasons one and two. What you can do is tell the inspector, in the statement of case, that reasons one and two are no longer pursued by the council or are addressed by amendments, and focus the evidence accordingly.

Severable and non-severable proposals

Severability is about the development, and it turns on whether the proposal comprises physically and functionally independent elements that could stand alone.

A single application for a house extension and a detached garage may be severable, because the garage could be built without the extension and the extension without the garage. An application for a dwelling with an access, where the access is the only means of serving the dwelling, is not. A mixed-use scheme where the retail element is integral to the residential podium is not. A phased scheme with independent phases sometimes is.

Where a proposal is genuinely severable, the authority can in principle issue a split decision, granting one element and refusing another, although not every authority will and there is no obligation on them to do so. Where a split decision has been issued, the refused element can be appealed on its own.

Ask for a split decision before determination rather than afterwards. Write to the case officer, identify the elements, explain why each stands alone, and ask for separate decisions. It costs nothing and it occasionally works.

Narrowing the issues instead

Where the proposal cannot be split, the realistic objective is to reduce the inspector's list of main issues, and that is done through the appeal documents rather than through any procedural device.

Three tools do the work.

The statement of common ground records what both parties agree, which can remove whole reasons for refusal from contention. Where the council concedes a reason, say so in the document and get it signed.

The statement of case sets out your position and identifies what remains in dispute. Be explicit: list each reason for refusal and state whether it is agreed, conceded by the council, addressed by an amendment, or contested.

Amendments made before the appeal is lodged can remove a reason entirely. Amendments after lodging are constrained, because an appeal tests the scheme that was refused and there are limits on how far a proposal can change without prejudicing anyone who commented on the original.

Our note on reading reasons for refusal covers how to sort the reasons into those categories before you commit to an appeal at all.

Inspector discretion to look wider

This is the risk that makes partial thinking dangerous.

Inspectors decide the appeal on its merits against the development plan and material considerations. They identify their own main issues, and those issues do not have to match the reasons for refusal. An inspector who considers that a scheme causes unacceptable harm to a neighbour's living conditions can dismiss on that basis even if the council raised no such concern and no neighbour objected.

Third party representations feed into this, and an objector who raises a point the council never took can put it in play, as our note on interested party representations explains.

The practical response is to address the whole scheme in the evidence even while concentrating the argument. A short section dealing with the points not in dispute, with the supporting evidence appended, protects you at no real cost. Leaving a topic out entirely invites a question you cannot answer on the day.

Consequences for the rest of the scheme

Think through the outcomes before lodging, because a partial win can be worse than a clean loss.

If the appeal succeeds, the permission is for the development as appealed. An inspector cannot grant permission for something materially different from what was before them, so a scheme you have mentally reduced to its uncontroversial parts is not what you will receive.

If the appeal is dismissed, the whole scheme falls, including the elements the council accepted. That is the cost of an unseverable proposal and it is why a resubmission of the accepted elements, running in parallel with the appeal, is often the sensible commercial hedge.

Conditions are the other half of this. Where the disputed element could be controlled rather than refused, propose a condition or an obligation that resolves it, and put the drafted wording in the appeal documents. Inspectors respond well to a worked condition and poorly to an assertion that something could be conditioned.

Drafting the appeal to limit the issues

A disciplined appeal statement does four things in the first two pages.

1. States the development as appealed, with the definitive drawing list and revision numbers.
2. Lists each reason for refusal and gives its current status in one line.
3. Identifies the matters genuinely in dispute as questions the inspector can answer.
4. Says what conditions or obligations are offered and attaches the draft wording.

Keep the tone factual. An appeal statement that spends four pages complaining about the council's handling of the application reads badly and does not shorten the inquiry. Where the council behaved unreasonably, that belongs in a separate costs application with its own evidence.

Consistency matters more than volume. The drawing list in the appeal form, in the statement, in the statement of common ground and on the drawings themselves should be identical, and the case rests on the same policy references in the Planning Statement that supported the original application unless you are deliberately changing position.

Alternatives to a partial appeal

Four options are usually worth testing before lodging.

A fresh application for the uncontested elements only, using the fee-free resubmission where it is available, which delivers a usable permission quickly while the disputed element is resolved separately.

A revised application addressing the disputed reason, which keeps the decision with the authority and preserves a right of appeal if it fails again.

A section 73 application where a suitable earlier permission exists and the problem is a condition rather than the development.

Negotiation with the case officer to secure a split decision on a severable proposal, which needs to happen before determination.

Appeal decisions on comparable schemes are useful for understanding how inspectors have treated similar issues, though they turn on their own facts and are not binding. Our note on using appeal decisions as evidence covers how to deploy them properly.
