Case summaries

R (Miller) v Prime Minister [2019] UKSC 41

The Prime Minister advised the Queen to prorogue Parliament for five weeks during the critical Brexit period. The Supreme Court unanimously held this advice was unlawful as it frustrated Parliament's constitutional functions without reasonable justification. The prorogation was declared null and of no effect.

R (Miller) v Secretary of State for Exiting the European Union [2017] UKSC 5

Following the 2016 EU referendum, the Government sought to trigger Article 50 TEU using prerogative powers. The Supreme Court held 8-3 that an Act of Parliament was required before ministers could notify withdrawal from the EU, as the 1972 Act created domestic legal rights that could not be removed by executive action alone.

R (on the application of A) v Secretary of State for the Home Department [2021] UKSC 37

A convicted sex offender challenged guidance on the Child Sex Offender Disclosure Scheme, arguing it insufficiently required police to consult him before disclosing his offences. The Supreme Court dismissed the appeal, clarifying that judicial review of policies requires showing they positively authorise or approve unlawful conduct, not merely that they leave uncertainty.

R (on the application of AB) v Secretary of State for Justice [2021] UKSC 28

A 15-year-old detained at a Young Offenders Institution challenged his removal from association with other inmates as violating Article 3 ECHR. The Supreme Court rejected arguments that solitary confinement of under-18s is automatically inhuman or degrading, holding that Article 3 requires a fact-sensitive assessment of all circumstances rather than applying bright-line rules.

R (on the application of AM (Belarus) v Secretary of State for the Home Department [2024] UKSC 13

AM, a Belarusian national and foreign criminal, deliberately thwarted deportation through lies and non-cooperation. He claimed his 'limbo status' without leave to remain violated Article 8 ECHR. The Supreme Court allowed the Secretary of State's appeal, holding that AM's own conduct in obstructing removal was highly material to the proportionality analysis and no violation of Article 8 arose.

R (on the application of Bano) v London Borough of Waltham Forest [2026] UKSC 22

Mrs Bano was offered private rented sector accommodation in Derby by Waltham Forest, which she refused. She later sought judicial review claiming the main housing duty continued. The Supreme Court held the duty ceased automatically on refusal of a compliant offer, and a statutory review under section 202 was her proper remedy.

R (on the application of Begum) v Special Immigration Appeals Commission & Anor [2021] UKSC 7

Shamima Begum, who left the UK aged 15 to join ISIL in Syria, had her British citizenship revoked by the Home Secretary on national security grounds. She challenged the refusal of leave to enter the UK to pursue her appeal. The Supreme Court held that national security concerns outweighed her right to an effective appeal, and courts must respect executive assessments on such matters.
