Local plan examination: what a soundness objection needs

A soundness objection to a local plan has to do three things: identify the part of the plan you say is unsound, name which of the four soundness tests it fails, and set out the modification that would cure it, in words the inspector could adopt. Representations that stop at the first two are read, logged and left alone. The examination is a test of the submitted plan, and an inspector who agrees with your diagnosis but has no proposed wording in front of them will usually leave the policy as it is.

The window for this is the Regulation 19 publication stage under the Town and Country Planning (Local Planning) (England) Regulations 2012, and it runs for at least six weeks. Miss it and you are outside the examination.

Why Regulation 19 is the only stage that counts

Regulation 18 consultation happens while the council is still deciding what its plan says. It is the right moment for arguing about strategy, and comments there can shift a direction of travel, but nothing from that stage goes to the inspector as a representation.

Regulation 19 is different in kind. The council publishes the plan it intends to submit, with its sustainability appraisal and its evidence base, and invites representations on two questions only: is the plan legally compliant, and is it sound. Those representations are then submitted to the Secretary of State with the plan under section 20 of the Planning and Compulsory Purchase Act 2004, and the appointed inspector works from them.

So the practical rule is simple. Whatever you want the inspector to consider must be in a Regulation 19 representation, made by the deadline, in your own name or your client's.

The four soundness tests

National policy sets out four tests, and an objection should be pinned to at least one of them explicitly.

Positively prepared asks whether the plan provides for objectively assessed needs, including any unmet need from neighbouring areas that it is reasonable for this authority to take, and whether it is consistent with achieving sustainable development.

Justified asks whether the plan is an appropriate strategy when considered against reasonable alternatives, based on proportionate evidence. This is where the sustainability appraisal and the site selection methodology get tested, and it is the test that most often produces a modification.

Effective asks whether the plan is deliverable over the plan period, including cross-boundary strategic matters. Deliverability arguments about specific allocations belong here: viability, land ownership, infrastructure sequencing, remediation costs.

Consistent with national policy asks whether the plan enables sustainable development in line with the National Planning Policy Framework, in the edition current at examination.

Legal compliance sits alongside soundness rather than inside it, covering the local development scheme, the statement of community involvement, sustainability appraisal, habitats regulations assessment and the strategic cross-boundary duties. A legal compliance failure is fatal to the plan in a way that unsoundness is not, so if you have one, say so separately and clearly.

Duty to co-operate arguments deserve a word of caution. The Levelling-up and Regeneration Act 2023 contains provisions to replace that duty with an alignment policy, and commencement has been staged, so check which regime applies to the plan in front of you and give the position as at the date of your representation. An objection built on the wrong framework is easy for the council to answer.

Writing a representation the inspector can use

Structure the document as the inspector will read it: by policy, then by test, then by remedy.

1. Identify the policy, paragraph or allocation reference exactly as it appears in the published plan. One representation per policy.
2. State which test or tests are failed, in one sentence.
3. Set out the evidence. Name the study, its author and its date, and quote the passage you rely on rather than referring to it in general terms.
4. Give the modification in tracked-change form. Strike the words you want removed, insert the words you want added, and keep it as short as the point allows.
5. Say whether you wish to participate in the hearing sessions, and why your presence would assist.

Two habits weaken otherwise good representations. The first is arguing the merits of a planning application that has not been made, which the inspector will not entertain. The second is length. A five page representation with a clear proposed modification carries more weight than a sixty page report that never quite says what should change.

Where the argument is about supply, the housing land supply position is the evidential battleground, and the site-by-site trajectory in the council's own housing land supply statement is usually more useful than a general critique of the methodology.

Hearings, and what actually happens in the room

The inspector publishes matters, issues and questions, and participants submit hearing statements against them. Those statements are where the argument is developed, and they matter more than the original representation.

Sessions are round table discussions led by the inspector, not adversarial hearings. There is no cross-examination and no evidence in chief. The inspector asks questions and expects direct answers, and a participant who reads out a prepared speech will be stopped.

Prepare by working out what the inspector needs before recommending your modification. That is usually one fact and one form of words. And be ready to concede the points that do not matter, because credibility on the point that does matter is the only thing you take into the room.

Where a neighbourhood plan covers part of the area, expect questions about how the emerging local plan sits alongside it, and where the council has produced a design code, expect the inspector to test whether it is being applied as policy or as guidance.

Main modifications and the second consultation

If the inspector concludes that changes are needed to make the plan sound, the council asks for main modifications to be recommended. Those modifications are published for consultation for at least six weeks, with any updated sustainability appraisal.

Representations at that stage are limited to the modifications themselves, which is a narrower gate than Regulation 19 but a real one. A modification drafted quickly by officers often does not achieve what the inspector intended, and pointing that out with alternative wording is frequently accepted.

The inspector's report then follows, and where the modifications are recommended the council adopts the plan with them incorporated.

Weight while the examination runs

An emerging plan is not nothing. Decision makers give it weight according to the stage it has reached, the extent of unresolved objections to the relevant policies, and the degree of consistency with national policy. A submitted plan with a policy attracting no objections carries real weight. The same plan's most contested allocation policy carries very little until the inspector reports.

That asymmetry is worth using. If you are promoting a site, an unresolved objection to the policy that would refuse it is itself a reason for reduced weight in the meantime.

For anyone promoting a specific site through examination, the technical evidence base is what makes the deliverability case credible, and you can check the evidence a site promotion needs against the constraints on the land.
