There have been some interesting precedences set by court cases throughout human history and this has to be one of the more interesting ones:
The 51-year-old man was fined under article 215 of France’s civil code, which states married couples must agree to a “shared communal life”.
[…]
But the 47-year-old ex-wife then took him back to court demanding 10,000 euros in compensation for “lack of sex over 21 years of marriage”.
The ex-husband claimed “tiredness and health problems” had prevented him from being more attentive between the sheets.
But a judge in the south of France’s highest court in Aix-en-Provence ruled: “A sexual relationship between husband and wife is the expression of affection they have for each other, and in this case it was absent.
So in France I guess the new ruling states both parties in a marriage will either put out or pay out. I’m guessing this precedence will be used quite extensive in France’s not too distant future.
