Grampian condition challenge fails where highway works had no real prospect

A developer could not rescue a 33-home scheme with a Grampian condition where the necessary road improvements depended on a highway authority exercising discretionary powers against the wishes of frontage owners, the High Court has found.

Deputy High Court Judge Karen Ridge refused John Lund permission to challenge an Inspector’s dismissal of an appeal for housing at Oddfellows Street, Cleckheaton. The John Lund judgment, handed down on 1st October 2026, found no arguable legal error in the Inspector’s assessment that the private street works had no realistic prospect of being completed within the proposed three-year permission period.

The case matters because it separates the legal possibility of carrying out works on third-party land from the practical prospect that the public authority with the necessary powers will actually use them. Funding the works and offering a unilateral undertaking were not enough when neither step compelled Kirklees Council, acting as highway authority, to begin the statutory process.

Why the Grampian condition was proposed

The appeal site was grassland allocated for housing, but access depended on Oddfellows Street. Part of the street was unadopted, lacked street lighting and was accepted by all parties to be unsuitable for the proposed development without improvement works.

The developer submitted an outline scheme of road improvements and offered a unilateral undertaking which would, in effect, meet the whole cost. The proposed restriction would prevent commencement or occupation until the improvements had been completed.

The remaining difficulty was legal and practical control. The works were to be delivered through Kirklees Council’s private street works powers under sections 205 to 208 of the Highways Act 1980. Those powers existed, but using them depended on the highway authority passing a resolution and choosing to act.

Frontage owners had objected during a 2024 consultation. The council’s highways department had also indicated that it would not exercise the powers unilaterally in the face of opposition. The Inspector therefore concluded that there was no prospect of the works being delivered within three years and dismissed the planning appeal on highway-safety grounds.

The court distinguished legal power from practical delivery

The claimant argued that opposition from landowners and political reluctance were immaterial planning considerations. He relied on British Railways Board v Secretary of State for the Environment and Hounslow LBC [1994] JPL 32, often cited in disputes about negatively worded conditions and works affecting land outside an applicant’s control.

Judge Ridge rejected that characterisation. The Inspector was not treating the landowners’ views as an objection to the planning merits of the houses. He was asking whether those objections affected the realistic prospect of the highway authority resolving to use its discretionary statutory powers.

Evidence about whether those powers were likely to be used was, the judge said, “plainly material”. The earlier British Railways Board authority did not answer that practical question because it concerned unwilling landowners and the merits of development, rather than the likelihood of a public authority initiating a statutory process.

For a Grampian condition, the distinction is narrow but important. The existence of a power can show that delivery is legally possible. It does not demonstrate that the body holding the power is willing, likely or able to exercise it within the lifetime of a permission.

Paying for the road did not compel the highway authority

The unilateral undertaking removed a significant financial uncertainty by promising to cover the improvement costs. It also sought to prevent the houses being commenced or occupied before the road was upgraded.

But it could not bind the highway authority to pass a section 205 resolution. Nor could it remove the practical and political uncertainties created by the frontage owners’ opposition. The judgment records that the local planning authority could not demand that the highway authority use a discretionary power, even though both functions sat within Kirklees Council.

The claimant also argued that formal objections under section 208 would be limited to owners asked to contribute to the costs. As he proposed to bear the whole cost, he said the landowners would have no relevant basis to object.

The court found that this missed the Inspector’s concern. The section 208 stage would arise only after the highway authority had first resolved to use the private street works code. The evidence indicated that it was unlikely to take that initial step while frontage owners remained opposed.

The Inspector applied the correct policy test

Government guidance says a negatively worded condition limiting development until works on other land have been completed may be appropriate in some cases. It also says such a condition should not be used where there are no prospects at all of the required action being performed within the time limit imposed by the permission.

The claimant argued that the Inspector moved inconsistently from saying the authority’s use of the powers was uncertain to finding there was no prospect of delivery within three years.

Judge Ridge found no contradiction. Read fairly and as a whole, the decision letter moved from the evidence to an evaluative conclusion. The Inspector had considered the need for member approval, the highways department’s position and the history of landowner objections before applying the policy test.

The progression from uncertainty to the final conclusion reflected reasoning, not inconsistency. The reasons were “adequate and intelligible”, and the challenge did not identify an arguable error of law.

What the Grampian condition judgment means in practice

The judgment does not establish that opposition from a third-party owner will always defeat a Grampian condition. It also does not turn an authority’s reluctance into an automatic veto over development.

Instead, it confirms that decision makers can look beyond bare legal possibility. Where delivery depends on a discretionary public power, the available evidence about whether that power is likely to be used can be central to deciding whether a Grampian condition offers a realistic solution.

Applicants should therefore distinguish four separate questions: whether the necessary works are technically defined, whether access or statutory powers exist, whether funding is secured, and whether the body controlling delivery is demonstrably prepared to act. Solving only the funding question may leave the scheme exposed.

A strong evidence package may include correspondence from the highway authority, an agreed route through member or officer approval, a realistic programme, evidence addressing third-party objections and a fallback if the preferred mechanism fails. Where that evidence is missing, a promise to pay may carry limited weight.

Permission to challenge was refused

The court refused permission to bring a section 288 challenge to the planning appeal decision dated 23rd December 2025. This was not a judgment after a full substantive hearing. That procedural status should not be overstated. The court nevertheless examined each proposed ground and concluded that none disclosed an arguable legal error.

The irrationality ground also failed. The Inspector was entitled to weigh the council’s wish to continue exploring options against the obstacles already identified and conclude that they would not be overcome within three years. Attempting to dispute that assessment was, the judge found, an effort to reargue the planning merits.

The judgment ends with the conclusion that the claim disclosed “no arguable error of law”. The appeal dismissal therefore stands. Any revised proposal would need to address the evidence about whether the necessary road improvements can actually be delivered.
