COURT OF JUSTICE OF THE EUROPEAN UNION
ALCHASTER II (AG Opinion) ■ Case C‑743/24 (Request for a preliminary ruling, Ireland)
The concept of “heavier penalty” contained in Article 49 of the Charter of Fundamental Rights does not cover a situation where a parole regime has been made stricter (from a right to automatic entitlement to release on licence once the first half of an imposed sentence has been served, to a right to release once at least two thirds of an imposed sentence has been served, dependent on an assessment conducted by Parole Commissioners).
EUROPEAN COURT OF HUMAN RIGHTS
M.B. v. SPAIN ■ Application no. 38239/22 ■ Fifth Section ■ 6 February 2025
Art 5 § 1 (e) ■ Imposition of a security measure of continued detention on the applicant on mental health grounds ■ Domestic courts’ assessment of the applicant’s mental health condition based on reports drafted almost two years before the measure’s imposition ■ No assessment of the applicant’s therapeutic or medical needs or the need to monitor her, and no mention of the prediction of future behaviour
Facts ■ The case concerned the imposition of preventive detention measures on the applicant following her acquittal on grounds of diminished responsibility.
In March 2018, the applicant was arrested and placed in pre-trial detention for setting fire to the flat in which she was living. Medical reports indicated that the applicant suffered from mental health disorders (this was confirmed four years after the fact, in April 2022, when the applicant was recognised as suffering from paranoid schizophrenia).
The applicant’s appeals against the decision to detain her in prison, and requests that she be admitted in a psychiatric hospital, were dismissed in March and May 2018. The applicant’s pre-trial detention was extended in February 2019.
In February 2020, the applicant was found responsible for an offence of aggravated arson by the Salamanca Audiencia Provincial but excluded from criminal responsibility owing to her mental health disorders. They imposed a security measure on the applicant entailing treatment in a secure unit for a period of between five and fifteen years. This security measure could be replaced by treatment in a mental health facility depending on the progress of the treatment and the relevant reports and assessments to be made during the execution of the judgment. In May 2020, the Audiencia Provincial prolonged the applicant’s pre-trial detention during the appeal proceedings.
The applicant’s applications before the Castile and León High Court, the Supreme Court and the Constitutional Court were unsuccessful.
The applicant was admitted to the prison psychiatric hospital of Alicante in July 2021. A year later, in June 2022, the Audiencia Provincial ordered the replacement of the applicant’s security measure to be served in a prison with her placement in a centre for persons with mental health problems. The applicant was transferred to such a centre in November 2023.
The applicant complained before the Court both about her pre-trial detention in spite of her state of health and her acquittal, and the imposition of a security measure.
Law ■ Article 5 § 1, 5 § 3 and 5 § 4 (pre-trial detention)
The Court upheld the Government’s preliminary objection of non-exhaustion of domestic remedies regarding her pre-trial detention.
(a) Initiation and prolongation of pre-trial detention by the investigating judge (March 2018, February 2019)
The Court observed that the applicant’s appeal against her initial placement in pre-trial detention (March 2018) was rejected by competent domestic courts and that no further appeal was made before the Constitutional Court. The prolongation of the applicant’s pre-trial detention (February 2019) was not challenged by the applicant.
Although the Court acknowledged the “vulnerable situation of the applicant, a foreign woman with a mental health condition who was held in pre‑trial detention in different locations during the criminal proceedings against her” (§ 48), it also noted that the lawyers representing her have provided legal assistance and have appealed several judgments and decisions, and that the applicant has not complained about the quality of the legal aid provided (§ 49).
It therefore saw no reason to consider that the applicant had been deprived of effective legal representation and upheld the Government’s objection.
(b) Prolongation of the pre-trial detention by the Audiencia Provincial (May 2020)
Although no appeals or requests for a review were lodged against the Audiencia Provincial to prolong the applicant’s pre-trial detention (May 2020), the applicant did mention her prolonged pre-trial detention in spite of her acquittal in her applications before the Supreme Court and the Constitutional Court.
The Court noted that the Supreme Court had not addressed this aspect of the applicant’s complaint, but also observed that the appeal before the Supreme Court was directed against the Audiencia Provincial’s judgment (February 2020), not against the decision to prolong the applicant’s pre-trial detention (May 2020).
Furthermore, the Court recalled that the Constitutional Court found the applicant’s complaint inadmissible for failure to exhaust domestic remedies – namely an action for the annulment of proceedings against the Supreme Court decision. The Court found this requirement to be “reasonable and foreseeable” and saw “no reasons […] to question it” (§ 54). The Court therefore upheld the Government’s objection.
Conclusion ■ Inadmissible
Law ■ Article 5 § 1 (security measure)
General principles: Ilnseher v. Germany [GC], nos. 10211/12 and 27505/14, § 127, 4 December 2018; Rooman v. Belgium [GC], no. 18052/11, § 192, 31 January 2019; Denis and Irvine v. Belgium [GC], nos. 62819/17 and 63921/17, § 125, 1 June 2021
The Court noted that the domestic courts (including the Audiencia Provincial in its judgment from February 2020 imposing the impugned security measure) based their judgments on medical reports prepared following the commission of the offence, i.e. two years earlier (March 2018). Neither the Audiencia Provincial nor the higher courts having reviewed its judgment conducted a thorough scrutiny of the medical reports and of the seriousness of applicant’s condition (§ 78).
Similarly, the Audiencia Provincial “made no reference to the applicant’s therapeutic or medical needs or to the need to monitor her in order to prevent her from, for example, causing harm to herself or others” (§ 79). The Court noted that the High Court having reviewed the judgment of the Audiencia Provincial stated that the imposition of the security measure “had been based on implicit reasons, without any further analysis of those reasons” (§ 76). The other judgments rendered by the High Court, the Supreme Court and the Constitutional Court “did not provide any kind of clarification on the potential risks posed by the applicant” (idem).
Consequently, the Court found that the imposition of a security measure on the applicant on mental health grounds fell short of guarantees against arbitrariness.
Conclusion ■ Violation of Article 5 § 1.
Article 41 ■ EUR 20,000 in respect of non-pecuniary damage.
PALFREEMAN v. BULGARIA (dec.) ■ Application no. 6035/19 ■ Third Section Committee ■ 11 February 2025
Art 10 ■ Disciplinary sanction for having stuck stickers critical of the prison administration ■ Stickers found to be offensive and not conveying an opinion ■ Sanction deemed proportionate
Art 13 ■ Lack of effectiveness of administrative remedy due to lack of independence from the prison administration not examined ■ Effectiveness of judicial remedy examined in concreto without taking into account uncertainties as regards judicial review of disciplinary punishments
Art 18 ■ Court not convinced that sanctions were used to silence a prisoners’ organisation
Facts ■ The applicant was the president of the Bulgarian Prisoners’ Rehabilitation Association (hereinafter “the BPRA”), founded by prisoners and former prisoners. He had also publicly criticised the prison authorities and the prison system.
At the time of the facts, he was being detained at the Kazichene open-type prison hostel. On 31 May 2018, prison officers found found eight stuck stickers, featuring an image similar to the BPRA’s logo (a raised first), but with the thumb wedged between two fingers (the so-called “fig sign”), and carrying the inscription: “When injustice is law, resistance becomes duty”.
The applicant denied having been involved in the distribution of the stickers. The authorities took the view that it was he who had affixed the stickers, that the image on them was obscene and that the wording was offensive to staff. In June 2018, he was given a disciplinary sanction of additional cleaning duties for seven days.
The applicant’s appeal before the governor of Sofia prison were rejected. The Sofia City Administrative Court opened a case into the events. After having heard witnesses, it concluded in April that it was the applicant who had stuck them. It considered that “the stickers had been offensive to prison staff, that they did not convey any value judgment or opinion, and that in sticking them in various places the applicant had breached the prison rules” (§ 8). It found the seven-day punishment to be adequate and proportionate. The Supreme Administrative Court upheld this judgment in December 2020.
The applicant complained under Articles 10 (freedom of expression) and 11 (freedom of assembly and association) of the imposition of disciplinary punishment in relation to the stickers; under Article 13 that he did not have an effective remedy in that respect; under Article 14 that he had been treated differently on account of his status as someone engaging in advocacy of prisoners’ rights.
He also claimed under Article 18 (limitation on use of restrictions on rights) that the real purpose of the disciplinary punishments had been to silence him and discourage the activities of the BPRA. The applicant stressed that he had been sanction after years spent in prison without disciplinary punishments, argued that the punishments complained of had been given in response to the submissions made by the BPRA had made submissions to the Committee of Ministers in relation to the execution of judgments of the Court on the conditions of detention in prisons, and to statements critical of the authorities made by the organisation regarding recent escapes from prison. The applicant had been sanctioned after years in prison without disciplinary punishments. The applicant lso referred to a television interview of 10 July 2018 of a then Deputy Minister of Justice, who had called the stickers “anti-State”.
Law ■ Article 10 and Article 13 ■ Disciplinary punishments related to the distribution of the stickers
The Court decided to examine this part of the complaint (the imposition of a seven-day additional cleaning duties in relation to the stickers) solely under Articles 10 and 13. The Court focused its analysis on the proportionality of the punishment.
The Court accepted the Sofia Administrative Court’s analysis that the stickers were offensive and did not “convey any value judgment or opinion” (§ 18): it declared that “a domestic court is best suited to reach conclusions in that regard, as it is well aware of the local meaning and significance of a particular depiction” (idem).
The Court also accepted the domestic courts’ analysis that the punishment of additional cleaning duties for seven days was appropriate and proportionate, “in the context of breach of prison rules” (§ 19). The Court rejected the applicant’s argument that the punishment had delayed his application for early release as being “speculative” (idem) and not supported by evidence.
As regards the alleged lack of effective remedy, the Court rejected the applicant’s arguments, namely that the administrative remedy had been ineffective (because the prison inspector reviewing the complaints was not independent from the prison governor) and that the judicial review was incertain because of a lack of clarity as to the judicial review of disciplinary punishments other than solitary confinement (see examples here).
As regards the administrative remedy, the Court declared it “does not have to assess the aptness of the administrative remedy resorted to” (§ 20). As regards the judicial remedy, the Court reminded that it is examining the cases in concreto, and observed that the applicant has access to two levels of judicial review (before the Sofia City Administrative Court and the Supreme Administrative Court). It is worth noting that the applicant submitted his case to the Court in January 2019, months before the Sofia City Administrative Court found the case admissible.
Conclusion ■ Inadmissible (manifestly ill-founded).
Law ■ Article 18 ■ Use of disciplinary punishments to silence a prisoners’ organisation
General principles: Merabishvili v. Georgia [GC], no. 72508/13, §§ 287-317, 28 November 2017
The Court saw “no sufficient proof that the sanctions against the applicant were undertaken in response to the stances taken by the BPRA, and in order to punish him for them” (§ 27). It saw no direct link between the organisation’s submission to the Committee of Ministers and statements on prison escapes, and the sanction complained of.
The Court also argued that the statements made in July 2018 by the Ministry Deputy of Justice against the stickers found was made after the punishments were pronounced. However, these statements were actually made before the prison inspector (subordinate to the Ministry of Justice) rejected the applicant’s internal complaints against the punishments, which then became final.
Conclusion ■ Inadmissible (manifestly ill-founded).
COURT OF JUSTICE OF THE EUROPEAN UNION
ALCHASTER II (AG Opinion) ■ Case C‑743/24 (Request for a preliminary ruling, Ireland) ■ 13 February 2025
Art 49(1) CFR ■ Principle of legality of criminal offences and penalties ■ Reference for a preliminary ruling ■ Trade and Cooperation Agreement between the European Union and the United Kingdom ■ Judicial cooperation in criminal matters ■ Arrest warrant ■ Adverse amendment to the parole system in the issuing State
Facts ■ The case concerns the surrender of MA by Ireland to the United Kingdom (UK), following arrest warrants issued by UK judges (Northern Ireland) in respect of four offences involving terrorism, alleged to have been committed between 18 and 20 July 2020. Cooperation in judicial matters between the UK and the European Union (EU) is governed by the Trade and Cooperation Agreement, entered into force in May 2021.
The Supreme Court of Ireland submitted that, should MA be surrendered to the UK and sentenced to imprisonment, his right to conditional release in the UK would be governed by legislation adopted after the alleged commission of the offences.
According to the new parole regime in force as of 30 April 2021 (which applies to offences committed before that date), persons convicted to a determinate custodial sentence may be released on parole after having served two thirds of the “appropriate custodial term” determined by the judge, provided that the Parole Commissioners are satisfied that their continued detention is not necessary for the protection of the public.
Prior to April 2021, persons sentenced to a fixed term of imprisonment were automatically released on parole after a “custodial period” that could not exceed half of the sentence imposed.
Consequently, the referring court considers that the amendments could result in MA remaining in prison for a longer period. Through a reference for preliminary ruling, it asked whether those amendments, which increase the term to be served in detention (from half to two thirds of a custodial period), and abolish a regime under which conditional release was automatic, “can still be regarded as relating solely to the enforcement of sentences or whether it must be considered as retroactively altering the very scope of the sentence” (§ 25).
Law ■ Article 49(1) of the Charter of Fundamental Rights (CFR)
Advocate General (AG) Spielmann based his reasoning on the ECtHR case law, chiefly the judgment Del Río Prada v. Spain [GC] (no. 42750/09, 21 October 2013, especially § 89). The AG saw no reason why Article 49 CFR should provide more extensive protection than Article 7 ECHR. Among other things, he argued that aligning Article 49 CFR with Article 7 ECHR would best serve the objective of a “high level of trust” between the EU and the UK “as regards respect for fundamental rights” (§ 103).
The AG insisted that the present case differs from Del Río Prada, in which legal changes totally deprived a prisoner from the possibility of obtaining sentence remissions (§ 74), since, as argued by the UK authorities at the hearing, prisoners are “always released, subject to a licence” during the last year of serving their sentence (§ 91). AG Spielmann explained that his task is therefore to examine whether in the present case there have been “a series of measures which have the effect of increasing the intrinsic seriousness of the sentence initially provided for” (§ 92).
As regards the change in the eligibility threshold for release on parole (from half to two-thirds of the custodial sentence), AG Spielmann argued that the “eligibility threshold for release on licence forms part of the execution of a sentence and, therefore, does not fall within the remit of Article 7(1) ECHR” (§ 89).
As regards the changes brought to the release procedure (from automatic release to release upon approval by the Parole Commissioners), although they specifically target those convicted of terrorist offences, which “could be construed as an indication that, in reality, the intention was to raise the penalty for such offences” (§ 94), AG Spielmann argued that they have not altered the penalty (see § 95 a reference to Hogben v. the United Kingdom, no. 11653/85, 3 March 1986, in which the measure complained of also targeted specific categories of offences).
Moreover, the “introduction of an assessment of the potential danger of an individual to the public appears […] to form part of prison policy” (§ 96), provided that the role of the Parole Commissioners is limited to examining whether the person concerned “poses a threat to the public at a given time, that the assessment is conducted thoroughly in accordance with a fixed protocol and that it is properly documented” (§ 97). Under these conditions, such assessment does not change the sentence, since “it is up to the individual at the moment [of the assessment] to act accordingly and show to the Parole Commissioners that he or she is fit to leave” (§ 96).
Conclusion ■ The concept “heavier penalty” contained in Article 49 CFR “does not, in principle, cover a situation where the legal provisions governing a parole regime have been amended to provide that a right to automatic entitlement to release on licence, once the first half of an imposed sentence has been served, has been replaced by a right to release once at least two thirds of an imposed sentence has been served, where that release is dependent on an assessment conducted by Parole Commissioners” (§ 107).
