Geoffrey Harold Stringer v Minister of Housing and Local Government and Another [1970] 1 WLR 1281
Stringer material considerations is a classic planning authority on the width of the phrase “material considerations” and on the rule that a local planning authority must not fetter its future planning discretion by contract.
The case arose from development near the Jodrell Bank radio telescope. The court held that the effect of proposed development on the operation of the telescope was capable of being a legitimate planning consideration, but an agreement by the county council to discourage development for a fixed future period unlawfully fettered its statutory discretion.

What Stringer decided
The dispute concerned proposed development in the vicinity of the Jodrell Bank radio telescope in Cheshire. Radio interference from development could affect the operation of the telescope.
Cheshire County Council had entered into an agreement with the University of Manchester under which it undertook to discourage certain development in the surrounding area until 1990.
Mr Justice Cooke held that the agreement went too far because the council had purported to bind the future exercise of its statutory planning powers. A public authority cannot contract away a discretion which Parliament requires it to exercise when future applications arise.
A planning authority cannot fetter its future discretion
A local planning authority may adopt policies, enter legitimate planning agreements and take a consistent approach to recurring issues. What it cannot do is promise in advance that it will exercise a statutory discretion in a predetermined way regardless of the circumstances of a later application.
The planning merits must still be considered when the statutory decision falls to be made.
That principle remains important whenever a council agreement, undertaking or policy appears to turn a future planning judgment into a contractual obligation.
Material considerations are not confined to neighbouring amenity
Stringer is also frequently cited for its broad explanation of what can qualify as a material planning consideration.
A consideration can be material where it relates to the use and development of land and serves a genuine planning purpose. The effect of development on the functioning of the Jodrell Bank telescope was therefore capable of being relevant even though it was not a conventional issue such as overlooking, traffic or visual amenity.
The public interest connection matters
The telescope was not simply a private commercial neighbour asking the planning system to protect its own interests. Its scientific function gave the interference issue a wider public-interest planning character.
The case therefore supports a broad but not unlimited approach. A matter does not become material merely because someone would prefer it to be considered; it needs a sufficient relationship to planning, land use or development.
The Minister could decide the appeal afresh
Although the council’s contractual fetter was unlawful, that did not mean the effect on Jodrell Bank had to be ignored in the planning appeal.
The Minister was exercising his own statutory function and could consider the relevant planning merits independently. The legitimate planning consideration survived even though the council’s attempt to predetermine how it would deal with the issue did not.
Why Stringer still matters
The judgment is useful for separating two questions which are sometimes confused: whether a matter is capable of being a material planning consideration, and whether a public authority has lawfully preserved its freedom to weigh that matter when the decision is actually made.
