The Local Government Finance Act 1988 introduced the Community Charge ("poll tax") in Scotland from 1989 and in England and Wales from April 1990, replacing domestic rates with a flat per-adult local charge. Mass non-payment, the March 1990 London riots, and acute political backlash precipitated Margaret Thatcher's resignation in November 1990 and the policy's full replacement by the Council Tax in 1993.
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.
