In seinem heute verkündeten Kammerurteil im Verfahren Stübing gegen Deutschland 
(Beschwerdenummer 43547/08), das noch nicht rechtskräftig ist1, stellte der 
Europäische Gerichtshof für Menschenrechte (EGMR) einstimmig fest, dass keine 
Verletzung von Artikel 8 (Recht auf Achtung des Privat- und Familienlebens) 
der Europäischen Menschenrechtskonvention (EMRK) vorlag. 
Der Fall betraf die Verurteilung des Beschwerdeführers zu einer Gefängnisstrafe wegen 
seiner Inzestbeziehung mit seiner jüngeren Schwester, die er, nachdem er in einer 
Pflegefamilie aufgewachsen war, erst als Erwachsener kennengelernt hatte und mit der 
er vier gemeinsame Kinder hat. 
Der Gerichtshof entschied insbesondere, dass die deutschen Behörden im Umgang mit 
dieser Frage einen weiten Beurteilungsspielraum hatten, da zwischen den Mitgliedstaaten 
des Europarats kein Konsens hinsichtlich der Frage besteht, ob einvernehmliche sexuelle 
Beziehungen zwischen Geschwistern eine Straftat darstellen. Im Übrigen hatten die 
deutschen Gerichte bei der Verurteilung des Beschwerdeführers eine sorgfältige Abwägung der Argumente vorgenommen.
 
 Zusammenfassung des Sachverhalts 
Der Beschwerdeführer, Patrick Stübing, geboren 1976, ist deutscher Staatsangehöriger 
und lebt in Leipzig. Als Siebenjähriger wurde er von einer Pflegefamilie adoptiert, 
nachdem er als Dreijähriger zunächst in einem Kinderheim untergebracht worden war. 
Nach seiner Adoption hatte er jahrelang keinen Kontakt zu seiner leiblichen Familie. 
Erst als er im Jahr 2000 wieder Kontakt zu seiner Herkunftsfamilie aufnahm, erfuhr Herr 
Stübing, dass er eine, 1984 geborene, leibliche Schwester hat. Nach dem Tod ihrer 
Mutter im Dezember 2000 entwickelte sich eine Liebesbeziehung zwischen den 
Geschwistern. Sie lebten mehrere Jahre zusammen und bekamen zwischen 2001 und 
2005 vier gemeinsame Kinder. 
Nach mehreren Vorstrafen wegen seiner Inzestbeziehung verurteilte das Amtsgericht 
Leipzig Herrn Stübing im November 2005 wegen Beischlafs zwischen Verwandten in zwei 
Fällen zu einer Freiheitsstrafe von einem Jahr und zwei Monaten. Unter Berufung auf ein 
Sachverständigengutachten, demzufolge seine Schwester eine ängstlich zurückgezogene 
Persönlichkeitsstruktur habe und in hohem Maße von ihm abhängig sei, schlussfolgerte 
das Gericht, sie sei nur teilweise schuldfähig und sah in ihrem Fall von einer Strafe ab. 
Nachdem das Oberlandesgericht Dresden das Urteil bestätigt hatte, legte Herr Stübing 
eine Verfassungsbeschwerde gegen seine Verurteilung ein. 
1 Gemäß Artikel 43 und 44 der Konvention sind Kammerurteile nicht  rechtskräftig. Innerhalb von drei Monaten nach der Urteilsverkündung  kann jede Partei die Verweisung der Rechtssache an die Große Kammer  beantragen. Liegt ein solcher Antrag vor, berät ein Ausschuss von fünf  Richtern, ob die Rechtssache eine weitere Untersuchung verdient. Ist das  der Fall, verhandelt die Große Kammer die Rechtssache und entscheidet  durch ein endgültiges Urteil. Lehnt der Ausschuss den Antrag ab, wird  das Kammerurteil 
rechtskräftig. 
Sobald ein Urteil rechtskräftig ist, wird es dem Ministerkomitee des  Europarats übermittelt, das die Umsetzung der Urteile überwacht. Weitere  Informationen zum Verfahren der Umsetzung finden sich hier:  www.coe.int/t/dghl/monitoring/execution. 
  
Pressemitteilung 
Das Bundesverfassungsgericht wies die Verfassungsbeschwerde mit Entscheidung vom 
26. Februar 2008 mit einer Mehrheit der Stimmen zurück. Es vertrat die Auffassung, 
dass die Strafbarkeit des Beischlafs zwischen leiblichen Geschwistern nach dem 
deutschen Strafgesetzbuch keinen Eingriff in den Kernbereich privater Lebensgestaltung 
darstelle. Wichtigster Grund für die Strafbarkeit sei der Schutz von Ehe und Familie, da 
Inzestverbindungen zu einer Überschneidung von Verwandtschaftsverhältnissen und 
sozialen Rollenverteilungen führten. Darüber hinaus seien der Schutz der sexuellen 
Selbstbestimmung und die Gefahr erheblicher Schädigungen der aus einer solchen 
Beziehung hervorgegangenen Kinder Gründe für das Verbot. Die in Frage stehende 
Strafnorm sei gerechtfertigt durch die Zusammenfassung dieser Strafzwecke vor dem 
Hintergrund der gesellschaftlichen Überzeugung, dass Inzest strafwürdig sei. 
  
Beschwerde, Verfahren und Zusammensetzung des Gerichtshofs 
Herr Stübing rügte seine Verurteilung wegen Beischlafs zwischen Verwandten. Er machte 
eine Verletzung von Artikel 8 EMRK geltend. 
Die Beschwerde wurde am 3. September 2008 beim Europäischen Gerichtshof für 
Menschenrechte eingelegt. 
Die Urteile wurden von einer Kammer mit sieben Richtern gefällt, die sich wie folgt 
zusammensetzte: 
Karel Jungwiert (Tschechien), Präsident, 
Boštjan M. Zupančič (Slowenien), 
Mark Villiger (Liechtenstein), 
Ann Power-Forde (Irland), 
Ganna Yudkivska (Ukraine), 
Angelika Nußberger (Deutschland), 
André Potocki (Frankreich), Richter, 
und Claudia Westerdiek, Sektionskanzlerin. 
  
Entscheidung des Gerichtshofs 
Der Gerichtshof schloss nicht aus, dass Herrn Stübings Verurteilung eine 
Beeinträchtigung seines Familienlebens darstellte. In jedem Fall war zwischen den 
Parteien unumstritten, dass die Verurteilung einen Eingriff in sein Recht auf Achtung des 
Privatlebens nach Artikel 8 darstellte, das auch sein Sexualleben mit einschloss. 
Seine Verurteilung war nach dem deutschen Strafgesetzbuch, das sexuelle Beziehungen 
zwischen leiblichen Geschwistern unter Strafe stellt und auf den Schutz der Moral und 
der Rechte anderer abzielt, gesetzlich vorgeschrieben. Daher verfolgte die Verurteilung 
einen legitimen Zweck im Sinne von Artikel 8. 
Der Gerichtshof war der Auffassung, dass die deutschen Behörden bei der Entscheidung, 
wie mit Inzestbeziehungen zwischen erwachsenen Geschwistern umzugehen sei, einen 
weiten Beurteilungsspielraum hatten. Zwischen den Mitgliedstaaten des Europarats 
besteht kein Konsens hinsichtlich der Frage, ob einvernehmliche sexuelle Beziehungen 
zwischen erwachsenen Geschwistern eine Straftat darstellen. In einer Mehrheit der 
Staaten sind solche Beziehungen allerdings strafbar. Darüber hinaus verbieten alle vom 
Gerichtshof in einer rechtsvergleichenden Untersuchung berücksichtigten Rechtssysteme, 
einschließlich derjenigen, die keine Strafbarkeit sexueller Beziehung vorsehen, die Ehe 
zwischen Geschwistern. Folglich besteht ein breiter Konsens dahingehend, dass sexuelle 
Beziehungen zwischen Geschwistern weder in der Rechtsordnung noch in der 
Gesellschaft im Allgemeinen anerkannt sind. Darüber hinaus gibt es keinen Beleg für die 
Annahme eines allgemeinen Trends zur Entkriminalisierung solcher Beziehungen. 
Schließlich berücksichtigte der Gerichtshof, dass der Fall eine Frage moralischer Maßstäbe betraf, in der Staaten nach seiner Rechtsprechung einen weiten Beurteilungsspielraum haben, wenn zwischen den Staaten kein Konsens besteht. 
Das Bundesverfassungsgericht hatte eine sorgfältige Abwägung der Argumente für und 
gegen die Strafbarkeit sexueller Beziehungen zwischen Geschwistern vorgenommen und 
war zu der Auffassung gelangt, dass mehrere Strafzwecke zusammengenommen die 
Verurteilung des Beschwerdeführers rechtfertigten, darunter der Schutz der Familie, die 
sexuelle Selbstbestimmung und die öffentliche Gesundheit, vor dem Hintergrund der 
gesellschaftlichen Überzeugung, dass Inzest strafwürdig sei. Es hatte berücksichtigt, 
dass sexuelle Beziehungen zwischen Geschwistern Familienstrukturen, und folglich die 
Gesellschaft insgesamt, ernsthaft beeinträchtigen könnten. Die sorgfältige Prüfung des 
Bundesverfassungsgerichts zeigte sich überdies auch darin, dass der Entscheidung eine 
ausführliche abweichende Meinung eines Richters beigefügt war. 
Nach Überzeugung der deutschen Gerichte war Herrn Stübings Schwester im Alter von 
sechzehn Jahren nach dem Tod ihrer Mutter eine Beziehung mit dem sieben Jahre 
älteren Bruder eingegangen. Sie habe an einer schweren Persönlichkeitsstörung gelitten 
und sei in hohem Maße von ihm abhängig gewesen. Die deutschen Gerichte hatten die 
Schlussfolgerung gezogen, dass sie nur teilweise schuldfähig sei. Vor diesem Hintergrund 
befand der Gerichtshof, dass die von den deutschen Gerichten verfolgten Zwecke nicht 
unangemessen waren. 
Der Gerichtshof gelangte daher zu der Auffassung, dass die deutschen Gerichte ihren 
Beurteilungsspielraum bei der Verurteilung Herrn Stübings nicht überschritten hatten. 
Folglich lag keine Verletzung von Artikel 8 vor. 
Das Urteil liegt nur auf Englisch vor.

JUDGMENT 
STRASBOURG 
12 April 2012 
This judgment will become final in the circumstances  set out in Article 44 § 2 of the Convention. It may be subject to editorial  revision.  
 
In the case of Stübing  v. Germany, 
The  European Court of Human Rights (Fifth Section), sitting as a Chamber  composed of: 
Karel Jungwiert, President,  
 Boštjan M. Zupančič,  
 Mark Villiger,  
 Ann Power-Forde,  
 Ganna Yudkivska,  
 Angelika Nußberger,  
 André Potocki, judges,  
and Claudia Westerdiek, Section Registrar, 
Having  deliberated in private on 13 March 2012, 
Delivers  the following judgment, which was adopted on that date: 
PROCEDURE 
1.  The  case originated in an application (no. 43547/08) against the Federal  Republic of Germany lodged with the Court under Article 34 of the Convention  for the Protection of Human Rights and Fundamental Freedoms (“the  Convention”) by a German national, Mr Patrick Stübing (“the applicant”),  on 3 September 2008. 
2.  The  applicant was at first represented by Mr E. Wilhelm, a lawyer practising  in Dresden, and by Mr K. Amelung, Mr S. Breitenmoser and Mr J. Renzikowski,  university professors teaching in Dresden, Basel and Halle, respectively;  subsequently, he was represented by Mr J. Frömling, a lawyer practising  in Zwenkau. The German Government (“the Government”) were represented  by their Agent, Mr H.-J. Behrens, of the Federal Ministry of Justice. 
3.  The  applicant alleged that his criminal conviction had violated his right  to respect for his private and family life. 
4.  On  17 June 2010 the President of the Fifth Section decided to give notice  of the application to the Government. It was also decided to rule on  the admissibility and merits of the application at the same time (Article  29 § 1). 
THE FACTS 
I.  THE CIRCUMSTANCES OF THE CASE 
5.  The  applicant was born in 1976 and lives in Leipzig. 
6.  At  the age of three, the applicant was placed in a children’s home and  later in the care of foster parents. At the age of seven, he was adopted  by his foster parents and was given their family name. After that, he  did not have any contact with his family of origin. 
7.  In  1984, the applicant’s biological sister, S. K., was born. The applicant  was unaware of his sister’s existence until he re-established contact  with his family of origin in 2000. Following their mother’s death  in December 2000, the relationship between the siblings intensified.  As from January 2001, the applicant and his sister had consensual sexual  intercourse. They lived together for several years. 
8.  In  2001, 2003, 2004 and 2005 four children were born to the couple. Following  the birth of the fourth child, the applicant underwent a vasectomy.  The three older children were placed in the care of foster families.  The youngest daughter lives with her mother. 
9.  On  23 April 2002 the Borna District Court (Amtsgericht) convicted the applicant of sixteen counts of incest  (Section 173 § 2 (2) of the Criminal Code, see “Relevant domestic  law”, below), gave him a suspended sentence of one year’s imprisonment  and put him on probation. 
10.  On  6 April 2004 the Borna District Court convicted the applicant of another  count of the same offence and sentenced him to ten months’ imprisonment. 
11.  On  10 November 2005 the Leipzig District Court convicted the applicant  of two counts of incest and sentenced him to one year and two months’  imprisonment. Including the sentence of 6 April 2004 and one further  previous criminal conviction, the District Court imposed a summary sentence  of one year and four months’ imprisonment. The court considered the  fact that the applicant had suffered physical abuse by his father during  the decisive first three years of his childhood to be a mitigating factor.  Furthermore, he had made a confession and had been affected by the media  coverage of his case. Lastly, he had previously been attacked during  detention. On the other hand, the court considered as aggravating factors  the fact that the applicant had reoffended in spite of his previous  convictions and that he had had unprotected intercourse with his sister  even though he had to have been aware of the risk of further pregnancies. 
12.  With  regard to the applicant’s sister, S. K., who had been charged with  the same offence, the Leipzig District Court, relying on an expert opinion,  found as follows: 
“The accused, K., has a very timid, withdrawn  and dependant personality structure. This personality structure, taken  together with [an] unsatisfying family situation, led to her being considerably  dependant on the applicant. In particular, after the death of their  mother, she experienced this dependency to an extent that she felt that  she could not live without him.” 
The  District Court concluded that this serious personality disorder, seen  in conjunction with established mild learning disabilities, had led  to her being only partially liable for her actions. Accordingly, the  court did not impose a sentence on her. 
13.  On  30 January 2007 the Dresden Court of Appeal rejected the applicant’s  appeal on points of law. The court considered that there were certain  doubts as to the constitutionality of the relevant provision. However,  it determined that these were not sufficient to call the validity of  the law into question. 
14.  On  22 February 2007 the applicant lodged a constitutional complaint, arguing,  in particular, that Section 173 § 2 (2) of the Criminal Code had violated  his right to sexual self-determination, had discriminated against him  and was disproportionate. In addition, it interfered with the relationship  between parents and their children born out of incestuous relationships. 
15.  On  26 February 2008 the Federal Constitutional Court, by seven votes to  one, rejected the complaint as being unfounded. The decision was based  on the following considerations. With the criminal provision of Section  173 § 2 (2) of the Criminal Code, the legislature had restricted the  right to sexual self-determination of biological siblings by making  sexual intercourse between them a punishable offence. This limited the  conduct of one’s private life by penalising certain forms of expressions  of sexuality between persons close to one another. However, the provision  did not infringe the core area of private life. Sexual intercourse between  siblings could have effects on the family and society and carry consequences  for children resulting from the relationship. As the criminal law prohibited  only a narrowly defined scope of behaviour and only selectively curtailed  opportunities for intimate contact, the parties concerned had not been  placed in a position which would be incompatible with respect for human  dignity. 
16.  The  legislator had pursued objectives that were not constitutionally objectionable  and that, in any event, in their totality legitimised the limitation  on the right to sexual self-determination. The primary ground for punishment  was the protection of marriage and the family. Empirical studies had  showed that the legislature was not overstepping its margin of appreciation  when assuming that incestuous relationships between siblings could seriously  damage the family and society as a whole. Incestuous relationships resulted  in overlapping familial relationships and social roles and, thus, could  damage the structural system of family life. The overlapping of roles  did not correspond with the image of a family as defined by the Basic  Law. It seemed clear, and did not appear to be far-fetched to assume,  that the children of an incestuous relationship might have significant  difficulties in finding their place within the family structure and  in building a trusting relationship with their closest caregivers. The  function of the family, which was of primary importance for the community,  would be decisively damaged if the required family structures were shaken  by incestuous relationships. 
17.  Insofar  as the criminal provision was justified by reference to the protection  of sexual self-determination, this objective was also relevant between  siblings. The objection that this right was sufficiently protected by  the specific provisions on offences against sexual self-determination  overlooked the fact that Section 173 of the Criminal Code addressed  specific situations arising from the interdependence and closeness of  family relationships, as well as difficulties in the classification  of, and defence against, transgressions of sexual self-determination  in that context. 
18.  The  legislature had additionally based its decision on eugenic grounds and  had assumed that the risk of significant damage to children who were  the product of an incestuous relationship could not be excluded. In  both medical and anthropological literature, which was supported by  empirical studies, reference had been made to the particular risk of  the occurrence of genetic defects. 
19.  The  impugned criminal provision was justified by the sum of the above-mentioned  objectives against the background of a common conviction that incest  should be subject to criminal liability. This conviction was also evident  on the international level. As an instrument for protecting self-determination,  public health, and especially the family, the criminal provision fulfilled  a signalling, norm-reinforcing and, thus, a general preventive function,  which illustrated the values set by the legislature and, therefore,  contributed to their maintenance. 
20.  The  impugned provision complied with the principle of proportionality. The  criminalisation of sibling incest was suitable for promoting the desired  objective. This was not put into question by the exemption of minors  from criminal liability (Art. 173 § 3), as the prohibition of acts  of sexual intercourse encompassed a central aspect of sexual relations  between siblings which contravened the traditional picture of the family  and which was further justified by its potential to produce descendants.  Neither was this assessment put into question by the fact that acts  similar to sexual intercourse and sexual intercourse between same-sex  siblings were not subject to criminal liability, while sexual intercourse  between natural siblings was punishable even in cases were conception  was excluded. The same applied to the objection that the criminal provision  was unsuitable for protecting the structure of the family because it  first impacted on siblings when they typically left the family circle  upon reaching the age of majority. 
21.  The  provision was also necessary. It was true that in cases of sibling incest  guardianship and youth welfare measures came into consideration. However,  these measures did not achieve the same objectives, as they were aimed  at preventing and redressing violations in specific cases, but did not  have any general preventive effect or reinforce societal norms in the  manner achieved through the law. 
22.  Lastly,  the Federal Constitutional Court considered that the criminal sanction  had not been disproportionate, as the provision had also allowed the  courts to refrain from imposing punishment in cases in which an accused’s  share of the guilt was slight. 
23.  Judge  Hassemer attached a dissenting opinion which was based on the following  considerations. Section 173 § 2 (2) of the Criminal Code was incompatible  with the principle of proportionality. The provision did not pursue  a legitimate aim. From the outset, considerations of eugenic aspects  were not a valid objective for a criminal law provision. Likewise, neither  the wording of the provision nor the statutory context indicated that  the provision was aimed at protecting sexual self-determination. Lastly,  the prohibition on sibling incest was not justified by the protection  of marriage and the family, as it only prohibited the act of sexual  intercourse, but did not prohibit any other sexual acts between siblings  or sexual intercourse between siblings of the same sex or between relatives  who were not blood-related. If the criminal provision were actually aimed  at protecting the family from sexual acts, it would also extend to these  acts that were likewise damaging to the family. The evidence seemed  to indicate that the provision as set out did not protect any specific  rights, but was solely aimed at moral conceptions. However, it was not  a legitimate aim for a criminal provision to build or maintain common  moral standards. 
24.  Furthermore,  the provision was not suited to attain the objectives pursued. As regards  the protection of the family from the damaging effects of incestuous  sexual acts, it was not far-reaching enough, as it did not encompass  similarly damaging behaviour and, moreover, acts committed by non-blood-related  siblings. It was too far-reaching because it encompassed behaviour that  could not (any longer) have damaging effects on the family because of  children having reached the age of majority and being about to leave  the family circle. 
25.  In  addition, there were other measures available that could have similarly  or even more effectively guaranteed the protection of the family, such  as youth welfare measures and measures taken by the family courts. Finally,  the impugned provision was excessive, at it did not provide for a limitation  of criminal liability resulting from behaviour which did not endanger  any of the possible objects of protection. 
26.  This  decision was served on the applicant’s counsel on 13 March 2008. On  4 June 2008 the applicant started serving his prison sentence. He was  released on probation on 3 June 2009. 
II.  RELEVANT DOMESTIC LAW 
27.  Section  173 of the German Criminal Code reads as follows: 
Incest 
“(1)  Whoever performs an act of sexual intercourse  with a consanguine descendant shall be punished with imprisonment for  no more than three years or a fine. 
(2)  Whoever performs an act of sexual intercourse  with a consanguine relative in an ascending line shall be punished with  imprisonment for no more than two years or a fine; this shall also apply  if the relationship as a relative has ceased to exist. Consanguine siblings  who perform an act of sexual intercourse with each other shall be similarly  punished. 
(3)  Descendants and siblings shall not be punished  pursuant to this provision if they were not yet eighteen years of age  at the time of the act.” 
Section  153 of the Code of Criminal Procedure reads as follows: 
“(1)  If a less serious criminal offence is the  subject of the proceedings, the public prosecution office may dispense  with prosecution with the consent of the ... court if the perpetrator’s  guilt is considered to be minor and [if] there is no public interest  in prosecution ... 
(2)  If charges have already been preferred, the  court, with the consent of the public prosecution office and the accused,  may terminate the proceedings at any stage thereof subject to the requirements  of subsection (1) ...” 
III.  COMPARATIVE LAW 
28.  Out  of thirty-one Council of Europe Member States, sixteen States (Albania,  Austria, Bosnia and Herzegovina, Bulgaria, Croatia, Cyprus, Czech Republic,  Finland, Greece, Iceland, Ireland, Liechtenstein, Macedonia, Moldova,  San Marino and Slovakia) the performance of consensual sexual acts between  adult siblings is considered a criminal offence, while in fifteen of  them (Armenia, Azerbaijan, Belgium, Estonia, Georgia, Latvia, Lithuania,  Luxembourg, Malta, Monaco, Montenegro, Portugal, Serbia, Slovenia and  Ukraine) it is not punishable under criminal law. The fact that one  of the siblings was adopted or raised in another household does not  in general seem to have any impact on criminal liability as long as  the siblings share at least one biological parent. In a few countries  (notably Iceland, Moldova and Slovenia) the ban on incest extends also  to adoptive siblings. 
29.  It  would appear that there are no plans to abolish the ban in the countries  concerned where the laws have generally been in force for decades. In  several countries there is even a tendency to widen the existing notion  of incest or to increase the penalties (e. g. Belgium, Croatia and the Czech Republic). Conversely,  incest between adult siblings has been decriminalised in Portugal in  1983 and in Serbia in 2006. 
30.  According  to an expert report prepared by the Max Planck Institute for Foreign  and International Criminal Law in November 2007 in the course of the  domestic proceedings, consensual sexual acts between siblings were criminalised  in eight further countries (Denmark, Italy, Poland, Romania, Sweden,  Switzerland, Hungary and the United Kingdom); and were not subject to  criminal liability in five further countries (France, the Netherlands,  the Russian Federation, Spain and Turkey). The international political  discussion on this issue was characterised by a tendency to decriminalise  the commitment of such acts. The Max Planck Institute further observed  that, even in those countries in which consensual acts between siblings  were not subject to criminal liability, siblings were not allowed to  marry. 
THE LAW 
I.  ALLEGED VIOLATION OF ARTICLE 8  OF THE CONVENTION 
31.  The  applicant complained that his criminal conviction had violated his right  to respect for his private and family life as provided in Article 8  of the Convention, which reads as follows: 
“1.  Everyone has the right to respect for his  private and family life, his home and his correspondence. 
2.  There shall be no interference by a public  authority with the exercise of this right except such as is in accordance  with the law and is necessary in a democratic society in the interests  of national security, public safety or the economic well-being of the  country, for the prevention of disorder or crime, for the protection  of health or morals, or for the protection of the rights and freedoms  of others.” 
32.  The  Government contested that argument. 
A.  Admissibility 
33.  The  Court notes that the application is not manifestly ill-founded within  the meaning of Article 35 § 3 (a) of the Convention. It further notes  that it is not inadmissible on any other grounds. It must therefore  be declared admissible. 
B.  Merits 
1.  Submissions by the applicant 
34.  The  applicant submitted that his criminal conviction had interfered with  his right to respect for his family life by preventing him from participating  in the upbringing of his children. Furthermore, the impugned judgment  and the underlying criminal liability had interfered and continued to  interfere with his sexual life, which formed a central element of his  private life. 
35.  There  had been no pressing social need justifying his criminal conviction.  A majority of legal scholars in Germany had advocated the repeal of  Section 173 of the Criminal Code. In a number of State Parties to the  Convention, sexual intercourse between consanguine siblings was not  subject to criminal liability. 
36.  The  reasons adduced by the Federal Constitutional Court had not sufficed  to assume the existence of a pressing social need justifying the applicant’s  conviction in this individual case. The criminal liability imposed on  incest was not suited to protect society as a whole from genetic diseases,  as scientific research had demonstrated that incestuous relationships  did not lead to a spreading of genetic diseases within society. Furthermore,  other individuals, who ran a much higher risk of transferring genetic  defects – such as women past the age of forty or known carriers of  a genetic defect – were not forbidden to procreate. The eugenic motivation  had its roots in the racist ideology of National Socialism. Neither  could the ban be justified by relying on the interests of potential  offspring, as it was impossible to assess the interest of potential  offspring in not being born. 
37.  The  criminal ban on incest was not suited to protect the family unit, as  it was inconsistent. There was no valid reason to limit criminal liability  to adult siblings, who were generally about to leave the family circle,  even though the potential harm done by incestuous relationships depended  on the intensity of the family relationship. On the other hand, there  was no valid reason to exempt step-, foster- or adoptive children from  liability. The same applied for the exclusion from liability of forms  of sexual contact other than sexual intercourse. 
38.  Contrary  to the Government’s submissions, incest between siblings was not liable  to jeopardise or destroy the family unit, but had to be regarded as  a symptom of already existing chaotic and dysfunctional family structures.  In the instant case, the applicant had been separated from his family  of origin as a young child. As the siblings had not been raised together,  the biological inhibition against incest could not have developed. There  were no other existing family members who could have been harmed by  the incest – on the contrary, the incestuous relationship created  a new family unit which had not existed before. Furthermore, the Federal  Constitutional Court had failed to take into account the fact that the  family relationship between the applicant and his biological sister  had been dissolved by the former’s adoption and by their long-standing  separation. 
39.  Neither  was the imposition of criminal liability suited to protect the interests  of prospective offspring, as incest between siblings – in contrast  with incest between parent and descendant – did not lead to overlapping  family roles. 
40.  The  applicant’s conviction had not been suited to protect his sister’s  right to sexual self-determination. There was no indication that Section  173 of the Criminal Code was aimed at protecting the weaker party in  a relationship. On the contrary, such cases fell within the range of  criminal provisions protecting sexual self-determination. In the instant  case, the sexual intercourse had been consensual and there had been  no indication of any form of sexual abuse. The courts had not considered  the case in question to be an impairment of the applicant’s sister’s  right of sexual self-determination. Neither had the applicant taken advantage  of a stronger position, which was demonstrated by the fact that his  sister had also been found to be guilty. It followed that she could  not be regarded as having been the victim of a punishable act. 
41.  Finally,  the criminal conviction could not be justified by the protection of  morals. Relying on the Court’s rulings in the cases of Dudgeon (Dudgeon v. the United Kingdom, 22 October 1981, § 52, Series  A no. 45) and Norris (Norris v. Ireland, 26 October 1988, § 46, Series A no. 142),  the applicant pointed out that particularly serious reasons had to be  put forward to justify interference into a most intimate aspect of one’s  private life. The applicant’s punishment had not been necessary to  maintain society’s taboo about incest. It could not be expected that  this taboo would weaken if the applicant had not been punished for having  had sexual intercourse with his sister. The applicant and his sister  had constantly avoided drawing public attention to themselves. Moral  indignation from certain individuals as regards the commitment of an  incestuous act could not on its own warrant the application of penal  sanctions. The removal of criminal liability would not imply that the  State approved of the commitment of such acts. 
42.  The  applicant’s conviction had been disproportionate having regard to  the circumstances of this particular case, in particular, the fact that  the applicant and his sister had not been raised together and had thus  been prevented from developing sexual inhibitions; that the applicant  had been punished before; that the siblings had developed a loving relationship;  the considerable burden the applicant’s conviction had imposed on  his four children; and the applicant’s infertility, which prevented  further procreation. 
43.  The  applicant finally submitted that the legislator, when enacting the pertinent  legislation, had considered that cases such as the present one could  be dealt with by dispensing with prosecution pursuant to Section 153  of the Code of Criminal Procedure, an option which the authorities had  failed to consider in the instant case. 
2.  Submissions by the Government 
44.  The  Government did not contest that the applicant’s criminal conviction  had interfered with his right to the enjoyment of his private and family  life. They considered, however, that this interference had been justified  under paragraph 2 of Article 8 as being necessary in a democratic society  in the interest of the prevention of disorder and for the protection  of morals. 
45.  The  domestic authorities had stayed within their margin of appreciation  when sanctioning consensual sexual intercourse amongst consanguine siblings,  as well as when punishing the applicant in the instant case. Referring  to the expert report prepared by the Max Planck Institute (see paragraph  30, above), the Government submitted that the differing approach to  liability for sexual intercourse between siblings within the Convention’s  area of application clearly showed that the national margin of appreciation  should be broad with regard to this issue, which was strongly influenced  by moral and cultural traditions. It followed that the Court should  restrict itself to deciding whether the interference with Convention  rights had exceeded every acceptable margin of appreciation. 
46.  When  the German legislator, in the early 1970s, had considered a reform of  the impugned legislation, a special committee set up by the Bundestag had reached the conclusion that the provision should  be maintained in the interests of the protection of marriage and the  family, of the protection of the weaker partner in a relationship and  of the prevention of genetic damage. All of these aims remained relevant  and had justified criminal liability being imposed on the applicant. 
47.  The  risk for the family structure was primarily created by the inversion  of social roles within the family, which existed independently of whether  and how closely the family actually lived together. The report by the  Max Planck Institute had confirmed that incestuous relationships were  liable to deepen and exacerbate existing problematic socio-psychological  relationships within a family. The damaging effect on the family structure  would have a direct negative effect on society. The legislator had thus  been entitled to assume that sexual intercourse between siblings, although  consensual, created knock-on effects which damaged the family and society  as a whole. 
48.  Section  173 of the Criminal Code had been targeted at protecting those persons  who became involved in a relationship due to the specific and typical  interdependence which was rooted in the family structure, and their  resulting difficulty in asserting and defending themselves from a stronger  partner. This aim was not fully coterminous with the aim of protecting  sexual self-determination, but rather dealt with a structural imbalance  regularly present in such relationships. This had been demonstrated  by the instant case, in which the Leipzig District Court, in its judgment  dated 10 November 2005, and relying on an expert opinion, had established  that the applicant’s sister was already dependent on him to an extent  that diminished her criminal liability. The fact that the vulnerable  person in the relationship had also been subject to criminal liability  did not call this into question, as long as that circumstance had been  appropriately taken into account during the criminal proceedings. 
49.  There  was empirical evidence that the risk of genetic damage among children  from an incestuous relationship was significantly increased. This aspect  alone would not justify criminalisation of consensual incest between  siblings, but could serve as supporting justification for imposing criminal  liability. 
50.  Finally,  Section 173 of the Criminal Code had served to maintain the taboo against  incest, which had cultural and historical roots and thus served to protect  morals within society as a whole. Relying on the reasoning delivered  by the Federal Constitutional Court, the Government submitted that imposing  criminal liability for incest was a suitable means of reflecting societal  convictions. It was such considerations, in particular, which allowed  criminal sanctions to be defined as a pressing social need and which  justified interference with the rights protected in Article 8 of the  Convention. 
51.  The  design of the criminal provision had not exceeded what was necessary  in a democratic society. The prohibition of sexual intercourse between  consanguine siblings was not contrary to the protective goals of the  legislature. This type of conduct endangered family structures in a  different way than other conduct of a sexual nature, or sexual intercourse  between step- or adoptive siblings. Likewise, the exclusion of minors  from criminal liability was justified by the fact that these cases regularly  involved difficult personal situations resulting from the development  of those minors, which justified the decision to waive criminal proceedings. 
52.  In  general, criminal proceedings could have a positive effect within the  scope of therapeutically addressing the effect of incest. Other measures  at the authorities’ disposal, such as measures taken by the family  courts or youth offices, did not go far enough compared with criminal  sanctions, as they lacked a general preventive effect or ability to  reinforce societal norms. 
53.  Furthermore,  the range of penalties for sexual intercourse between siblings was moderate.  Public prosecutors had a number of instruments available to them to  react to specific situations, which ranged from the dispensing with  a prosecution pursuant to Section 153 of the Code of Criminal Procedure  to waiving the application of any penalty imposed by a court. 
54.  The  applicant’s criminal conviction had also been justified by the circumstances  of this individual case. The Leipzig District Court had dealt extensively  with the facts that spoke in favour of the applicant. That court had  given detailed reasons why it found it necessary to impose a prison  sentence on the applicant. In this respect, the court had been allowed  to take into account the fact that the applicant had reoffended in spite  of his previous convictions for the same offence. 
3.  Assessment by the Court 
55.  The  Court does not exclude that the applicant’s criminal conviction had  an impact on his family life and, possibly, attracted protection under  Article 8 of the Convention, as he was forbidden to have sexual intercourse  with the mother of his four children. In any event, it is common ground  between the parties that the applicant’s criminal conviction interfered  with his right to respect for his private life, which includes his sexual  life (see Dudgeon, cited above, § 41 and Norris, cited above, § 38; also compare Laskey, Jaggard and Brown v. the United Kingdom, 19 February  1997, § 36, Reports of Judgments and Decisions 1997-I). The Court considers  that there is no reason to hold otherwise and endorses this assessment.  The applicant’s criminal conviction thus interfered with the applicant’s  right to respect, at least, for his private life. 
56.  An  interference with the exercise of the right to respect for an applicant’s  private life will not be compatible with Article 8 § 2 unless it is  “in accordance with the law”, has an aim or aims that is or are  legitimate under that paragraph and is “necessary in a democratic  society” for the aforesaid aim or aims (see, among many other authorities, Pretty v. the United Kingdom, no. 2346/02, § 68, ECHR 2002-III). 
57.  The  Court notes that the applicant’s criminal conviction was based on  Section 173 § 2 (2) of the German Criminal Code, which prohibits consensual  sexual intercourse between consanguine adult siblings and which is aimed  at the protection of morals and of the rights of others. It follows  that the measure in question pursued a legitimate aim within the meaning  of paragraph 2 of Article 8. 
58.  It  thus remains to be determined whether the applicant’s conviction was  necessary in a democratic society. In this respect, the Court must examine  whether there existed a pressing social need for the measure in question  and, in particular, whether the interference was proportionate to the  legitimate aim pursued, regard being had to the fair balance which has  to be struck between the relevant competing interests at stake and the  margin of appreciation enjoyed by the State (see, among many other authorities, A, B and C v. Ireland [GC] no. 25579/05, § 230, ECHR 2010). 
59.  The  Court reiterates that a number of factors must be taken into account  when determining the breadth of the margin of appreciation to be enjoyed  by the State when determining any case under Article 8 of the Convention.  Where a particularly important facet of an individual’s existence  or identity is at stake, the margin allowed to the State will normally  be restricted (see, for example, Dudgeon, cited above, § 52; Christine Goodwin v. the United Kingdom [GC], no. 28957/95,  § 90, ECHR 2002-VI; and Evans v. the United Kingdom [GC], no. 6339/05, § 77, ECHR  2007-IV). Accordingly, the Court has found that there must exist particularly  serious reasons before interference on the part of public authorities  concerning a most intimate aspect of private life, such as the manifestation  of a person’s sexuality, can be legitimate for the purposes of paragraph  2 of Article 8 (see Dudgeon and Norris, both cited above, §§ 52 and 46, respectively). 
60.  Where,  however, there is no consensus within the Member States of the Council  of Europe, either as to the relative importance of the interest at stake  or as to the best means of protecting it, particularly where the case  raises sensitive moral or ethical issues, the margin will be wider.  By reason of their direct and continuous contact with the vital forces  of their countries, the State authorities are, in principle, in a better  position than the international court to give an opinion, not only on  the “exact content of the requirements of morals” in their country,  but also on the necessity of a restriction intended to meet them (see,  among other authorities, A, B and C, cited above, § 232, and Handyside v. the United Kingdom, 7 December 1976, § 48, Series  A no. 24 ). 
61.  Applying  the principles set out above to the instant case, the Court observes  that there is no consensus between the member States as to whether the  consensual commitment of sexual acts between adult siblings should be  criminally sanctioned (see paragraphs 28-30, above). Still, a majority  of altogether twenty-eight out of the forty-four States reviewed provide  for criminal liability. The Court further notes that all the legal systems,  including those which do not impose criminal liability, prohibit siblings  from getting married. Thus, a broad consensus transpires that sexual  relationships between siblings are neither accepted by the legal order  nor by society as a whole. Conversely, there is no sufficient empirical  support for the assumption of a general trend towards a decriminalisation  of such acts. The Court further considers that the instant case concerns  a question about the requirements of morals. It follows from the above  principles that the domestic authorities enjoy a wide margin of appreciation  in determining how to confront incestuous relationships between consenting  adults, notwithstanding the fact that this decision concerns an intimate  aspect of an individual’s private life. 
62.  The  Court reiterates that in cases arising from individual applications  it is not the Court’s task to examine domestic legislation in the  abstract. Rather, it must examine the manner in which the relevant legislation  was applied to the applicant in the particular circumstances of the  individual case (see Pretty, cited above, § 75, ECHR 2002-III; Sommerfeld v. Germany [GC], no. 31871/96, § 86, ECHR 2003-VIII; and Zaunegger v. Germany, no. 22028/04, § 45, 3 December 2009).  Furthermore, it is not the Court’s task to rule on the degree of individual  guilt or to determine the appropriate sentence of an offender, those  being matters falling within the exclusive jurisdiction of the national  criminal courts (see Gäfgen v. Germany [GC], no. 22978/05, § 123, ECHR 2010-...,  and Öneryıldız v. Turkey [GC], no. 48939/99, § 116, ECHR 2004-XII). The Court will therefore limit its examination to the question  of whether the applicant’s criminal conviction in this individual  case corresponded to a pressing social need, as required by Article  8 § 2 of the Convention. 
63.  The  Court observes that the Federal Constitutional Court, having analysed  the arguments put forward in favour of and against criminal liability  and relying on an expert opinion, concluded that the imposition of criminal  liability was justified by a combination of objectives, including the  protection of the family, self-determination and public health, set  against the background of a common conviction that incest should be  subject to criminal liability. The Federal Constitutional Court considered  that sexual relationships between siblings could seriously damage family  structures and, as a consequence, society as a whole. According to the  court, criminal liability was further justified by reference to the  protection of sexual self-determination. By addressing specific situations  arising from the interdependence and closeness of family relationships,  section 173 of the Criminal Code could avoid difficulties in the classification  of, and defence against, transgressions of sexual self-determination  in that context. 
64.  The  Court notes that according to the findings of the Leipzig District Court,  the applicant’s sister first entered into a sexual relationship with  the applicant following their mother’s death. At that time, the sister  was sixteen years of age; the applicant was her senior by seven years.  According to an expert opinion prepared before the District Court, the  sister suffered from a serious personality disorder which, together  with an unsatisfying family situation and mild learning difficulties,  led to her being considerably dependent on the applicant. The District  Court concluded that the sister was only partially liable for her actions.  These findings were confirmed by the Dresden Court of Appeal and by  the Federal Constitutional Court. 
65.  The  Court considers that the above-mentioned aims, which had been expressly  endorsed by the democratic legislator when reviewing the relevant legislation  in the 1970s (see paragraph 46 above), appear not to be unreasonable.  Furthermore, they are relevant in the instant case. Under these circumstances,  the Court accepts that the applicant’s criminal conviction corresponded  to a pressing social need. 
66.  Having  particular regard to the above considerations and to the careful consideration  with which the Federal Constitutional Court approached the instant case,  which is demonstrated by the thoroughness of the examination of the  legal arguments put forward by the applicant and further highlighted  by the fact that a detailed dissenting opinion was attached to the text  of the decision, and to the wide margin of appreciation enjoyed by the  State in the absence of a consensus within the Member States of the  Council of Europe on the issue of criminal liability, the Court concludes  that the domestic courts stayed within their margin of appreciation  when convicting the applicant of incest. 
67.  There  has accordingly been no violation of Article 8 of the Convention. 
FOR THESE REASONS, THE COURT UNANIMOUSLY 
1.  Declares the application admissible; 
2.  Holds that there has been no violation of Article 8 of the  Convention. 
Done in English, and notified in writing  on 12 April 2012, pursuant to Rule 77 §§ 2 and 3 of the Rules of Court.
