The Town and Country Planning Act 1947, enacted by the Attlee government and effective 1 July 1948, nationalised development rights — requiring planning permission from local authorities for any change of land use — and introduced a 100% development charge on land-value uplift (later abolished). It empowered counties and county boroughs to prepare statutory development plans binding on subsequent decisions. The intended effect was to embed comprehensive land-use planning in the post-war reconstruction state, channel building according to Greater London Plan and New Towns priorities, and capture private windfall from public planning decisions.
Per invariant 3, reforms are scored by what they did on each channel-separated axis, not by the party that enacted them. This fingerprint is how the policy-match engine finds historical analogues.
Explicit links are curated by the author. Inferred links are hypotheses in the library that test the same axes this policy moved — the framework's answer to "what does the data say about a policy like this?".
Ranked by axis-fingerprint overlap with this policy. Direction match bolded — those are the closest historical analogues. Shape of the match is what drives policy-outcome comparison, not the country or party label.
