R (on the application of Guardians of Whitewebbs Park CIC) v London Borough of Enfield [2026] EWHC 1916 (Admin)

Whitewebbs Park is an important High Court judgment on planning committee transparency, background papers and biodiversity evidence. Enfield granted permission for Tottenham Hotspur’s proposed women’s and girls’ training centre at Whitewebbs Park, but the permission was quashed because a key ecology consultation response had not been made public and the officer report materially misrepresented the position on biodiversity net gain.

What Whitewebbs Park decided

The planning application proposed a football training centre and restored parkland at the former Whitewebbs Park Golf Course in Enfield. The scheme included training pitches and buildings for Tottenham Hotspur’s women’s and girls’ academy alongside public park improvements.

The planning committee approved the application by seven votes to four, with one abstention. Guardians of Whitewebbs Park CIC challenged the decision on several grounds.

The challenge succeeded on two closely related points concerning ecological evidence and the way that evidence was presented to councillors. The other challenges on local policy, heritage, Green Belt and apparent bias failed.

The council ecologist’s response was a background paper

Under section 100D of the Local Government Act 1972, certain background papers relied on in a committee report must be identified and made available for public inspection.

The court held that the council ecologist’s consultation response was such a background paper. It contained substantive professional advice about biodiversity net gain and directly informed the officer report.

The council had extracted the convenient conclusion that there was no ecological objection, while the underlying document made clear that the ecologist did not accept the applicant’s claimed 33% BNG figure. Sir Tim Kerr described this as an impermissible form of salami slicing.

The independent ecology audit was also a background paper

An independent audit by Plumb Associates was another background paper. The court considered the failure to list that document less serious because the gist of its conclusions had been fairly summarised in the officer report.

That distinction is useful. Not every failure to list a document will automatically invalidate a planning decision. The legal consequences depend on the document, what the public and councillors were told, and whether the omission caused material prejudice.

The officer report materially misled the committee on BNG

The officer report created the impression that Enfield’s ecologist supported the applicant’s position that the scheme would deliver 33% biodiversity net gain. He did not.

The ecologist accepted that the statutory biodiversity requirements could ultimately be met, but he had significant reservations about the applicant’s calculations and did not endorse the claimed 33% figure.

The court held that this disagreement was material. The committee was entitled to know the true professional position rather than a simplified account that removed the qualification.

BNG was not treated as an automatic reason for refusal

Whitewebbs Park should not be read as saying that disagreement about an applicant’s BNG percentage automatically requires refusal.

The judgment recognised the statutory biodiversity gain regime and the scope for the biodiversity gain condition and, where applicable, off-site measures to secure the required minimum. The legal failure was the lack of transparency and the misleading presentation of evidence to the decision-makers.

The vote mattered when the court considered whether to quash

Enfield argued that the court should refuse relief because the outcome would highly likely have been the same. The court did not accept that argument.

The committee vote was seven to four with one abstention. Given the nature of the missing and misleading ecology information, the court could not conclude that the statutory test for withholding a remedy had been met. The planning permission was therefore quashed.

The Green Belt, heritage and bias grounds failed

The claimant also challenged the council’s approach to local policy, heritage and Green Belt matters. Those grounds failed.

An apparent-bias challenge also failed. The earlier land transaction with Tottenham Hotspur and hospitality involving the football club did not establish apparent bias on the part of the planning committee. The court distinguished legitimate predisposition from unlawful predetermination.
