R (Royal Mint Court Residents’ Association) v Secretary of State for Housing, Communities and Local Government and London Borough of Tower Hamlets [2026] EWHC 2002 (Admin)
Royal Mint Court is the Divisional Court judgment on the Secretary of State’s decision to grant planning permission and listed building consent for redevelopment of Royal Mint Court as an embassy for the People’s Republic of China.
The challenge was dismissed. The court considered a set of unusual planning issues created by the diplomatic status of the site, alongside more familiar questions of enforceability, disclosure, procedural fairness, application information and human rights.

The site already had diplomatic status
The People’s Republic of China acquired Royal Mint Court in 2018. Diplomatic consent had been granted under the Diplomatic and Consular Premises Act 1987, subject to the requirement to obtain the necessary planning and listed building consents.
That meant the premises enjoyed diplomatic inviolability under the Vienna Convention. The practical consequence was that ordinary physical enforcement powers could not simply be exercised inside the mission premises without consent.
Planning conditions did not have to be physically enforceable in the ordinary way
The residents argued that the Secretary of State had not properly grappled with whether planning conditions and obligations could be enforced against diplomatic premises.
The court rejected that ground. The Secretary of State had taken the site’s diplomatic status into account, including the limitations on entry and ordinary enforcement.
He was entitled to rely on the Vienna Convention duty to respect the laws of the receiving state, the expectation of compliance, and the diplomatic remedies available if obligations were not honoured.
The law did not require him to attach a numerical probability to future compliance.
The undisclosed security material did not make the process unfair
The challenge also concerned a Security Statement and a Blast Assessment which had not been disclosed to residents during the planning process.
The court accepted that the Blast Assessment contained more detail than the material in the public domain. But the important underlying risks had already been identified in officer reports and in evidence submitted on behalf of residents.
The assessment of the likelihood of those risks by counter-terrorism specialists was central. The court found no material procedural unfairness or substantial prejudice. It also concluded that the outcome would in any event have been highly likely to be the same.
Redacted plans did not invalidate the application
Another ground relied on article 7 of the Development Management Procedure Order. The argument was that redactions and the absence of detailed room-by-room use information meant the application did not contain the information necessary to describe the development.
The court rejected that argument as unarguable.
Whether further information is necessary to describe a development is a matter of planning judgment for the decision-maker. On the information available, it was rationally open to the Secretary of State to conclude that the applications could be determined without the additional detail sought by the residents.
The human-rights ground also failed
Residents relied on fears concerning protests, terrorism, coercion and their proximity to the proposed embassy.
The court held that the Secretary of State had addressed the relevant safety and protest issues and was entitled to rely on the expertise of the Metropolitan Police and other specialist agencies.
The residents had not demonstrated the reasonable and convincing evidence needed to establish that the planning decision itself would expose them to a likely Convention-rights violation.
The court was reviewing legality, not the merits of the embassy
The judgment repeatedly distinguishes the planning merits from the legal task of the court. The political, diplomatic and ethical controversy surrounding the proposed embassy was not itself the question before the Divisional Court.
The issue was whether the Secretary of State had lawfully exercised the planning and listed-building functions entrusted to him. The court held that he had.
