BBC NEWS | Europe | Couple stand by forbidden love: "The couple's lawyer, Endrik Wilhelm, has lodged an appeal with Germany's highest judicial body, the federal Constitutional Court in Karlsruhe, in order to overturn the country's ban on incest.
'Under Germany's criminal code, which dates back to 1871, it is a crime for close relatives to have sex and it's punishable by up to three years in prison. This law is out of date and it breaches the couple's civil rights,' Dr Wilhelm said.
'Why are disabled parents allowed to have children, or people with hereditary diseases or women over 40? No-one says that is a crime."
