Coming out of the EU is the case of a German brother and sister who are suing for their right to continue as husband and wife.
Patrick Stuebing, 31, and his sister Susan Karolewski, 23, have four children together - two of which have disabilities.
The couple's lawyers claim that the law forbidding incest is an "infringement of the fundamental right to sexual self-determination, and thus unconstitutional".
While the couple claim that they didn't meet until they were adults and subsequently fell in love, the question here should involve the extent to which so-called sexual self-determination affects the greater society. Their chosen defense, employing a "sexual self-determination" construct, implies that sexuality is self-determined, rather than a pure function of genetic makeup. Should their standard prevail, homosexual activists stand to lose, because many of their arguments to date have been predicated upon nature, rather than nurture or some combination thereof.
A decision upholding the perspective of self-determination would amount to a crippling blow to the activists - while effectively undermining scientific and social proscriptions involving incest.
This is a lose-lose lawsuit.
