The judgment extensively references several key cases that have shaped the interpretation of Articles 5 and 14 ECHR in the context of prisoner rights:

• Brown v Parole Board for Scotland [2018] AC 1: This case clarified the scope of Article 5 obligations, specifically delineating when Article 5 applies to prisoners and the associated rehabilitation opportunities.
• Stott v Secretary of State for Justice [2018] 3 WLR 1831: Highlighted the necessity for evidence when alleging differential treatment under Article 14, emphasizing that abstract claims without substantiated evidence are insufficient.
• Re Farrell's Application [1999] NIJB 143 (CA): Established the cautious approach courts take in interfering with lower court judgments unless there's a clear error in the exercise of discretion.
• James v United Kingdom [2010] C-584/08: Provided guidance on what constitutes a "real opportunity for rehabilitation" under Article 5, stressing the importance of timely access to rehabilitative programs.
• R(Clift) v Secretary of State for the Home Department [2007] 1 AC 484: Recognized the right to early release under Article 5 for certain prisoners, establishing a framework for comparing treatment among different prisoner categories.

The Court of Appeal's reasoning centered on the necessity of providing substantive evidence when alleging differential treatment. Article 14 requires not only the existence of a difference in treatment but also that this difference is unjustified and lacks adequate justification. Aiken failed to demonstrate explicit evidence that his access to rehabilitative courses was less favorable compared to indeterminate sentence prisoners. The court emphasized that merely positing a hypothetical discrimination based on the operational framework of Article 5 does not suffice. Furthermore, the Court referenced precedents indicating that delays in rehabilitation access do not inherently constitute Article 5 breaches unless they significantly impede rehabilitation efforts.

Additionally, the court underscored that Aiken was not in an analogous position to indeterminate sentence prisoners, as the eligibility and procedural contexts for release differ between ECS and indeterminate sentences. This lack of analogy further weakened his Article 14 claim, as comparators in Article 14 claims must be in similar situations, which was not the case here.

This judgment reinforces the high evidential threshold required for successful Article 14 claims alleging differential treatment. It underscores that applicants must provide concrete evidence of how their treatment deviates from comparators in analogous situations. For practitioners, this case signifies the importance of meticulously documenting instances of alleged discrimination to substantiate claims under Article 14. Furthermore, it clarifies that operational delays, even if frustrating for the appellant, do not automatically equate to human rights breaches unless they demonstrably hinder rehabilitation or risk reduction efforts.

On a broader scale, the decision delineates the boundaries between extended custodial sentences and indeterminate sentences concerning prisoners' rights and rehabilitation opportunities. It highlights that legislative distinctions between different types of sentences inherently influence the rights and treatment of prisoners, which must be carefully navigated when asserting claims of discrimination or differential treatment.

Article 5 ECHR

Article 5 of the European Convention on Human Rights guarantees the right to liberty and security. In the context of prisoners, it encompasses the obligation to provide a real opportunity for rehabilitation, which includes timely access to rehabilitative courses that can aid in reducing the risk of reoffending.

Article 14 ECHR

Article 14 prohibits discrimination in the enjoyment of the rights and freedoms set forth in the Convention. To invoke Article 14, an individual must demonstrate that they possess an "other status," are subjected to differential treatment compared to a relevant comparator group, and that this differential treatment lacks adequate justification.

Extended Custodial Sentence (ECS)

An ECS is a fixed-term sentence that includes a period of custody followed by a licence period. Unlike indeterminate sentences, ECS prisoners are released after serving half of their custodial term, subject to parole, regardless of ongoing risk assessments.

Indeterminate Custodial Sentence

An indeterminate custodial sentence allows for indefinite detention based on the prisoner's ongoing assessment of risk to the public. Release depends on evaluations by parole commissioners who determine whether continued detention is necessary for public safety.

Differential Treatment

Differential treatment refers to one group being treated differently from another in a way that is less favorable, without adequate justification. Under Article 14, such differences must be objectively justified to be lawful.
