In the matter of an application by James Hugh Allister and others for Judicial Review (Northern Ireland)
[2023] UKSC 5
Article 7(1) ECHR prohibits retroactive application of heavier penalties.
Article 7(1) ECHR
Article 7(1) ECHR distinguishes between changes to the penalty itself and changes to its execution.
Del Río Prada v Spain, Uttley v United Kingdom
Article 5(1) ECHR guarantees the right to liberty and security, requiring laws authorizing deprivation of liberty to be accessible, precise, and foreseeable.
Article 5(1) ECHR, Del Río Prada v Spain
The Supreme Court allowed the Ministry of Justice's appeal and dismissed the respondents' cross-appeal.
The 2021 Act did not redefine or modify the scope of the penalties imposed (determinate custodial sentences), but rather changed the manner of their execution. The changes were foreseeable and did not breach Article 7(1) ECHR. The changes also complied with Article 5(1) ECHR as the lawfulness of detention was established by the initial sentences.
