Recent UK legislative reform has further empowered the UK Executive, degrading horizontal and vertical constraints on powers interfering with human rights, and this has largely taken place via the ‘back door’ through repeated marginalisation of Parliament. Between 2021 and 2023, 11 pieces of primary legislation were given Royal Assent which narrowed Executive accountability mechanisms in relation to coercive and administrative powers identified as weakening human rights protections by the Joint Committee on Human Rights. Echoing both recent and long-standing trends in UK law-making, such reform has been sent through Parliament while employing mechanisms of parliamentary marginalisation, undermining the ability of parliamentarians and broader civil society to scrutinise the changes. The passing of a constitutionally significant group of legislation in this manner created a ‘back door’ through which the UK Executive was able to expand its powers with minimal scrutiny. Such backdoor Executive empowerment supports scholarship highlighting the lack of firm UK constitutional constraints of the Executive. While the paper’s analysis does not make a claim on the overall status of UK democracy, it does argue that the recent legal reform mirrors dynamics identified with respect to democratic erosion, suggesting the need for further assessment of the UK’s democratic health.
