Miller-Mead v Minister of Housing and Local Government [1963] 2 QB 196
Miller-Mead is an important early Court of Appeal authority on how strictly an enforcement notice should be read and when a defect can be corrected rather than making the notice a nullity.
The case remains useful when distinguishing between an amendable defect and a notice that has fundamentally failed to identify the breach or the steps required.

An enforcement notice must tell the recipient what is alleged
An enforcement notice must identify the alleged breach sufficiently clearly and state what is required to remedy it. A recipient must be able to understand the case they have to meet.
But the Court rejected the idea that every drafting error automatically destroys the notice.
Some defects can be amended
Where the true substance of the alleged breach is clear and an error can be corrected without causing injustice, the appeal machinery may permit the notice to be amended or narrowed rather than quashed outright.
The important question is whether the proposed correction changes the substance of the case in a way that deprives the appellant of a fair opportunity to meet it.
A fundamental defect is different
Miller-Mead does not mean that every defective enforcement notice is salvageable. A notice that attacks the wrong development, fails to identify the breach in an intelligible way or would require a substantive rewriting may still be invalid.
Planning permission runs with the land
The judgment also reflects the important planning principle that the legal effect of a planning permission is determined by the permission itself. It is not ordinarily cut down by limitations appearing only in the applicant’s original intentions or application material unless those limitations have been properly incorporated into the permission.
Why Miller-Mead matters
The case sits behind the modern approach to enforcement notice amendment. When a notice contains an error, the practical question is not simply whether the drafting is imperfect, but whether the defect can lawfully be corrected without injustice and without changing the essential allegation.
