Minister for Justice, Home Affairs and Migration v King

Factual and Procedural Background

The Appellant challenged an order surrendering him from the executing state to the requesting state under the Trade and Cooperation Agreement (“TCA”). He faced eleven allegations of indecent assault and one of gross indecency involving two sisters, his stepchildren at the relevant time. The alleged offences occurred in the 1970s and 1980s, more than forty years before the proceedings. [1][2][3]

The High Court ordered surrender on 8 December 2025. The Supreme Court granted leave to appeal on 20 March 2026. The remaining objections concerned retrospective punishment, delay, and interference with private and family life; the appeal focused almost exclusively on retrospective punishment. [2][3][4][5][6]

The Appellant relied on counsel’s opinion that, if convicted, he would probably receive a longer sentence than if sentenced closer to the alleged offending, owing to tougher sentencing attitudes towards sexual offences. The Appellee did not dispute that prediction or provide contrary expert evidence. It was nevertheless accepted that any sentence must remain within the statutory maximum applicable when the alleged offences occurred. [7][8][9]

The judgment was delivered on 5 November 2026. [10]

Legal Issues Presented

1. Whether Article 7 ECHR prohibits a sentence exceeding the sentence probably imposed under earlier sentencing practice, although remaining within the statutory maximum applicable when the offence occurred. [11][12]
2. Whether Article 49 of the Charter provides broader protection against retrospective punishment and therefore prevents surrender under the TCA. [13][14][15][16]
3. Whether uncertainty concerning Article 49 required a preliminary reference to the Court of Justice of the European Union (“CJEU”) under Article 267 TFEU. [17][14][9][18]
4. What assessment and evidential foundation are required when fundamental rights are invoked to resist surrender under the TCA, as distinct from surrender between EU Member States. [19][20][21][22]

Arguments of the Parties

Appellant’s Arguments

• A likely increase in the actual sentence, compared with historical sentencing practice, constituted a heavier retrospective penalty prohibited by Article 7 ECHR and Article 49 of the Charter, notwithstanding compliance with the historical statutory maximum. [13][9]
• Alternatively, the interpretation of Article 49 was sufficiently uncertain to require a CJEU reference before surrender could be ordered. [9][18][23][24]
• The High Court’s reliance on comparable sentencing practice in the executing state did not itself demonstrate compliance with the Convention, Charter, or Constitution. [25]
• The Appellant also maintained objections based on delay and private and family life, although retrospective punishment was the appeal’s principal focus. [3][4][5][6]

Appellee’s Position

• The Appellee did not challenge counsel’s prediction of a likely heavier sentence and submitted no contrary opinion. The judgment does not give a comparably detailed account of the Appellee’s legal submissions. [7]

Court’s Reasoning and Analysis

1. The relevant distinction was between legal punishment and sentencing practice

The Court accepted the factual prediction that contemporary sentencing attitudes could produce a longer sentence. However, the Appellant would be prosecuted under the historical legislation, and neither the later offences nor their higher statutory maxima would apply. The dispute therefore concerned a change in sentencing assessment within an unchanged legal ceiling, not retrospective application of a higher statutory penalty. [101][102][30][8][9]

The Court considered the natural meaning and historical purpose of the prohibition on retrospective punishment to focus on the penalty prescribed by law. Neither Article 7 nor Article 49 refers to the sentence that a particular court would probably have imposed decades earlier. The historical statutory maximum fixes the ceiling; sentencing judges need not reconstruct earlier judicial attitudes. [29][103][11][12][52]

2. Article 7 ECHR did not prevent surrender

The requesting state remained a Convention Contracting State. Under Stapleton, Convention issues could ordinarily be addressed through its courts, absent a reason to doubt effective enforcement or an established breach. This supplied one basis for rejecting the Article 7 objection. [67][68][69]

Independently, Uttley and Coëme established that Article 7 concerns punishment authorised by the law applicable when the offence occurred, rather than a hypothetical sentence under earlier practice. The Court acknowledged criticism of aspects of Uttley but regarded this interpretation as firmly established and fatal to the Convention ground. [33][34][75][36][77][76]

3. Charter scrutiny applied to surrender, not directly to the prospective trial

The surrender decision implemented EU law and therefore attracted Charter obligations. The prospective prosecution and sentence did not themselves involve implementation of EU law, even on the assumption that the requesting state had remained an EU Member State. The Court warned against treating surrender and prosecution as a single process governed by one legal system. [40][104][105][106][107]

The Court left unresolved the precise extent to which Charter respect requires correspondence between the requesting state’s law and Charter standards outside the Charter’s direct scope. The appeal failed even on the more demanding assumption that the relevant sentencing system had to accord with Article 49. [108][109][110]

4. The TCA required an independent but demanding risk assessment

Alchaster required a specific examination of the Appellant’s circumstances under the single-stage Petruhhin approach. Neither the requesting state’s Convention membership nor Article 52(3) could substitute for that assessment. The two-stage Aranyosi and Căldăraru framework applicable between EU Member States did not govern TCA surrender. [19][95][96][20][111]

Nevertheless, a different assessment process did not necessarily imply a different outcome or a low threshold for refusal. The TCA itself reflected substantial mutual confidence, longstanding rights protection, and the EU’s collective judgment that criminal cooperation with the requesting state was appropriate. Those matters remained relevant, although not independently decisive. [99][112][113][93]

A refusal required objective, reliable, specific, and properly updated information establishing substantial grounds for a real risk of a relevant rights breach. Speculative or hypothetical arguments were insufficient. Relevant materials could include authoritative judgments and reports from international bodies. [22][41][42][114]

5. The expert opinion did not establish a Charter breach or a need for referral

The expert opinion established only the likelihood of a longer sentence. It did not explain why Uttley or Coëme was wrong, identify authoritative material supporting a broader Article 49 interpretation, or conclude that the anticipated sentence would breach either provision. Existing judicial authority instead weighed strongly against the Appellant. [115][116][117]

The Court also identified no common constitutional tradition supporting a broader Article 49 guarantee in this context. The wording of the provisions and the comparative material supported the legally authorised maximum as the relevant ceiling. Consequently, the evidence neither satisfied the refusal test nor created sufficient uncertainty to require an Article 267 reference. [118][52][116][117]

6. Broader observations were distinguished from the dispositive reasoning

The Court raised concerns that divergent interpretations of corresponding Charter and Convention rights could generate unnecessary appeals, references, and delay. It discussed possible approaches to Article 52(3) and the territorial limits of Charter protection without resolving those wider questions as prerequisites to deciding this appeal. [119][120][121][110][122]

It further distinguished uncertainty over whether an individual will encounter particular treatment from the legal question whether that treatment breaches the applicable standard. A “real risk” assessment should not replace resolution of the underlying legal issue or dilute the threshold for refusal. [123][124][63][65][125]

Holding and Implications

The appeal was dismissed. The High Court correctly ordered surrender: the objection did not satisfy the fundamental-rights refusal test, and no CJEU reference was required. [117][126]

The direct effect was that the surrender order remained in place. A likely heavier sentence resulting from contemporary sentencing practice, within the historical statutory maximum, did not establish the asserted Article 7 or Article 49 obstacle. [9][76][52][117]

The judgment also provided broader guidance: fundamental-rights refusals under the TCA should remain exceptional, convincingly substantiated by authoritative evidence, and assessed consistently with the requirement for urgent surrender procedures. The Court’s wider questions about Charter interpretation and extraterritorial standards remained open. [110][122][114][127][128]
