A couple of German brothers who had an incestuous relationship and would have claimed a right to family life lost a case that moved with the European Court of Human Rights.
The court said that Germany was allowed to ban incest. The case was unusual because his brother was adopted and never knew his biological sister before looking for his family as an adult.
The two, Patrick Stuebing and Susan Karolewski, had four children together, two of which are described as having physical disabilities.
The brother had been convicted of a crime of incest and served three year sentence in Germany.
The European court reaffirmed the decision of the Supreme Court of Germany, stating that classify incest as a crime does not violate the fundamental right to 'respect for private and family life' as guaranteed by the European Convention of Human Rights, said the site of the magazine 'Der Spiegel '.
According to the publication, the seven judges who examined the case decided unanimously that the German court's decision should be respected.
Speaking to the BBC in 2007, Patrick said he had regained his sister Susan when he was 23 years old when he traveled to Leipzig in 2000 to meet his biological family.
After his mother's death, the two said they had fallen in love.
She said not to feel guilt for incestuous relationship, and expected to change German law.
Patrick said the Justice destroyed his family.
