constitutional and that the prohibition of retrospective punishment under the German
Basic Law did not extend to measures such as preventive detention, which had always
been understood as differing from penalties under the Criminal Code’s twin-track system
of penalties on the one hand and measures of correction and prevention on the other.
In August 2009, Mr Jendrowiak, who had been diagnosed with cancer, was released, his
preventive detention having been suspended on probation by the Karlsruhe Regional
Court.
Complaints, procedure and composition of the Court
Relying in particular on Articles 5 § 1 and 7 § 1, Mr Jendrowiak complained of the
retrospective extension of his preventive detention – until his release - beyond the
maximum period of ten years authorised at the time of his offence.
The application was lodged with the European Court of Human Rights on 10 August
2004.
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),
Isabelle Berro-Lefèvre (Monaco),
Ann Power (Ireland),
Angelika Nußberger (Germany), Judges,
and also Claudia Westerdiek, Section Registrar.
Decision of the Court
Article 5 § 1
In terms of the temporal course of events, Mr Jendrowiak’s case was a follow-up case to
the application M. v. Germany, in which the Court found that the retroactive extension of
a prisoners’ preventive detention had not been justified.
The Court saw no reason to depart from its findings in that judgment. It considered that
there had been no sufficient causal connection between Mr Jendrowiak’s conviction by
the sentencing court and his continued deprivation of liberty beyond the period of ten
years in preventive detention to be covered by Article 5 § 1 (a) as being detention "after
conviction" by the sentencing court. When the sentencing court ordered his preventive
detention in 1990, that decision meant that he could be kept in that form of detention
for a clearly defined maximum period. Without the amendment of the Criminal Code in
1998 the court responsible for the execution of sentences would not have had
jurisdiction to extend the duration of the detention.
Mr Jendrowiak’s continued detention had not been justified under any of the other sub-
paragraphs of Article 5 § 1. In particular, it had not been justified by the risk that he
could commit further serious offences if released, as those potential offences were not
sufficiently concrete and specific so as to fall under sub-paragraph (c) of Article 5 § 1.
The Court was aware of the fact that the domestic courts had ordered Mr Jendrowiak’s
preventive detention beyond a period of ten years because they considered that there
was still a risk that he might commit serious sexual offences, in particular rape, if
