ECHR 241 (2012)  
07.06.2012  
Two prisoners should not have been placed in preventive  
detention retrospectively  
In today’s Chamber judgments in the cases K v. Germany (application no. 61827/09)  
and G v. Germany (no. 65210/09), which are not final1, the European Court of Human  
Rights held, unanimously, that there had been:  
A violation of Article 7 § 1 (no punishment without law) of the European  
Convention on Human Rights in both cases.  
The cases concerned the applicants’ placement in preventive detention, which had been  
ordered retrospectively, based on a legal provision introduced years after their  
conviction.  
The Court confirmed its findings in previous cases that preventive detention was to be  
qualified as a “penalty” for the purposes of the Convention. It held in particular that by  
ordering the applicants’ preventive detention retrospectively the German courts had  
imposed a heavier penalty on them than that applicable at the time of their respective  
offences.  
Principal facts  
The applicants in both cases are German nationals who were born in 1957 and 1968  
respectively. Mr K is currently detained in Schwalmstadt Prison and Mr G is detained in  
Straubing Prison. Mr K was convicted of several counts of rape and sentenced to eight  
and a half years’ imprisonment in 1987. Mr G was convicted of three counts of murder  
and sentenced to 15 years’ imprisonment in 1992.  
In both cases, in addition to their respective prison sentence, the sentencing courts  
ordered the applicants’ placement in a psychiatric hospital, where they were detained  
subsequent to serving their full prison sentence. Their stay there was terminated by the  
regional courts dealing with the execution of sentences in 2007, holding that the  
applicants did not suffer from  
a condition diminishing their respective criminal  
responsibility. Both applicants were subsequently placed in preventive detention, ordered  
by the Frankfurt regional court in March (Mr G) and April (Mr K) 2008 on the basis of  
Article 66b § 3 of the Criminal Code. That provision had been inserted into the Criminal  
Code in 2004 and allowed for the possibility to impose preventive detention  
retrospectively. In both cases, the regional court found that  
a comprehensive  
assessment of the applicants, their offences and their development during the placement  
in the psychiatric hospital revealed that it was very likely that, if released, they would  
commit serious offences again resulting in considerable psychological or physical harm to  
the victims.  
1 Under Articles 43 and 44 of the Convention, this Chamber judgment is not final. During the three-month  
period following its delivery, any party may request that the case be referred to the Grand Chamber of the  
Court. If such a request is made, a panel of five judges considers whether the case deserves further  
examination. In that event, the Grand Chamber will hear the case and deliver a final judgment. If the referral  
request is refused, the Chamber judgment will become final on that day.  
Once a judgment becomes final, it is transmitted to the Committee of Ministers of the Council of Europe for  
supervision of its execution. Further information about the execution process can be found here:  
The Federal Court of Justice dismissed both applicants’ appeals. On 5 August 2009, the  
Federal Constitutional Court declined to consider the applicants’ constitutional complaints  
against the retrospective orders for their preventive detention (file nos. 2 BvR 2633/08  
and 2 BvR 2098/08). It found in particular that Article 66b § 3 of the Criminal Code and  
the lower courts’ decision to order the applicants’ placement in preventive detention  
were compatible with the Basic Law.  
The applicants subsequently brought proceedings to review their preventive detention;  
both applicants are currently still in preventive detention.  
Complaints, procedure and composition of the Court  
Relying in particular on Article 7 § 1, the applicants complained of the retrospective  
order for and execution of their preventive detention.  
Mr K’s application was lodged with the European Court of Human Rights on 16 November  
2009 and Mr G’s application was lodged on 9 December 2009.  
Judgment was given by a Chamber of seven, composed as follows:  
Dean Spielmann (Luxembourg), President,  
Karel Jungwiert (the Czech Republic),  
Boštjan M. Zupančič (Slovenia),  
Mark Villiger (Liechtenstein),  
Ann Power-Forde (Ireland),  
Angelika Nußberger (Germany),  
André Potocki (France), Judges,  
and also Stephen Phillips, Deputy Section Registrar.  
Decision of the Court  
Article 7 § 1  
The Court referred to its conclusions in a previous case, M. v. Germany2, in which it had  
found that preventive detention under German criminal law was to be qualified as a  
penalty for the purpose of Article 7 § 1, having regard to the fact that it was ordered by  
the criminal courts following a conviction for a criminal offence and that it entailed a  
deprivation of liberty of indefinite duration. It saw no reason to depart from that finding.  
The Court was not convinced that the conditions of the applicants’ preventive detention  
in Schwalmstadt Prison, where Mr K remained detained and where Mr G had been  
detained prior to his transfer to another prison, had differed substantially from the  
situation of the applicant in the case of M. v. Germany, whose preventive detention had,  
moreover, been executed in that same prison. Minor alterations in the detention regime  
could not mask the fact that that there had been no substantial difference between the  
execution of the prison sentence and that of the preventive detention order. In a leading  
judgment of 4 May 2011, the German Federal Constitutional Court had moreover found  
it unconstitutional that there was not a sufficient difference between preventive  
detention and detention for serving a term of imprisonment under German criminal law.  
The Court agreed with the applicants’ argument that the retrospective order for their  
preventive detention constituted a new, additional penalty, and thus a heavier penalty

M. v. Germany (19359/04) of 17 December 2009

within the meaning of Article 7 § 1. At the time of their offences, committed in 1985 and  
1986 in the case of Mr K and between 1988 and 1990 in the case of Mr G, it had not  
been possible to place the applicants in preventive detention by retrospective order. The  
provision on which their preventive detention was based had only been inserted into the  
German Criminal Code in 2004, thus many years after their offences.  
In both cases, the sentencing court had expressly declined to order the applicants’  
preventive detention in addition to their placement in a psychiatric hospital. Those  
judgments could therefore not be said to have covered their subsequent placement in  
preventive detention. Moreover, under the established case-law of the German courts  
prior to the change in criminal law in 2004, a person could no longer be detained in a  
psychiatric hospital and had to be released if he no longer suffered from a condition  
excluding or diminishing his criminal responsibility.  
Finally, the Court did not agree with the German Government’s argument that by  
ordering the applicants’ release they would have breached their obligations under Article  
2 (right to life) and Article 3 (prohibition of inhuman or degrading treatment) of the  
Convention to protect potential victims from murder or violent sexual offences likely to  
be committed by the applicants. The Court underlined that the Convention neither  
obliged nor authorised State authorities to protect individuals from criminal acts of a  
person by measures which were in breach of that person’s right under Article 7 § 1.  
There had accordingly been a violation of Article 7 § 1 in both cases.  
Article 41  
Under Article 41 (just satisfaction) of the Convention, the Court held that Germany was  
to pay Mr K 7,000 euros (EUR) in respect of non-pecuniary damage. It was to pay Mr G  
EUR 5,000 in respect of non-pecuniary damage and EUR 7,140 in respect of costs and  
expenses.
