What the policy did

Illegal Migration Act 2023 (Royal Assent 20 July 2023) imposed a duty on the Home Secretary to remove those arriving irregularly and restricted their ability to claim asylum in the UK. Safety of Rwanda (Asylum and Immigration) Act 2024 (Royal Assent 25 April 2024) legislatively deemed Rwanda a safe country for asylum processing, responding to the November 2023 Supreme Court ruling in AAA v SSHD. Paired with a £500m+ treaty payment to Rwanda. No removal flight took place under Sunak; scheme scrapped by Starmer government in July 2024. Skilled Worker salary threshold raised to £38,700 (April 2024) and student dependant route closed (January 2024).

Policy-content fingerprint — what this policy moved, on which axes

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.

intended

↓

immigration openness

regulatory.immigration_openness

Immigration policy openness — work visas, family reunification, asylum processing, border enforcement posture.

decreased · strong

more restrictive (lower caps, tighter enforcement)

Statutory restriction of asylum route, raised skilled-worker salary threshold, student dependant closure.

↓

judicial independence

institutional.judicial_independence

Independence of the judiciary from executive and legislative encroachment. Specifically captures court-packing, selective prosecution, judicial reshuffles.

decreased · weak

weaker judicial independence

Legislatively overriding the Supreme Court's factual finding on Rwanda is a contested case of legislative versus judicial primacy; weak-negative coding reflects the scoped nature of the override.

Empirical evidence — linked hypotheses

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?".

The net fiscal contribution of immigrants (taxes paid minus public services + transfers received, measured in lifetime NPV terms) varies systematically by (a) origin-country institutional quality, (b) skill level at arrival, (c) age at arrival, (d) duration of residence, and (e) legal status (working-age visa / family reunification / asylum).

Per-capita crime rates (measured by police-recorded offences per 100k population, by offence type) among foreign-born residents in developed destination countries are NOT systematically higher than among native-born residents once age, gender, and socioeconomic status are controlled.

Across a broad panel of economies 1980-2020, stronger judicial independence — measured by V-Dem judicial-constraints-on-the- executive index, Fraser EFW integrity of the legal system, and the Cingranelli-Richards physical-integrity-rights index — predicts lower investment volatility and stronger long-run GDP per capita growth following major reform episodes.
