-Removed-But what is in that contract? All I have is a marriage certificate. We said some vows, but they weren't written down. As far as I know, it would be illegal for me to marry again (in most countries) if I don't first get a divorce (or annulment), but I am not aware of very many other legal restrictions. There are some issues to do with money, and taxes but I don't think they are very clearly stated in a 'marriage contract'.
-Removed-Purely on the idea of adultery itself been viewed as a illegal act, i would still maintain it is better categorized as an immoral/sinful act and closer aligned to 'greed' or 'lust' than failure to pay one's taxes.
1.luxuria (lechery/lust)
2.gula (gluttony)
3.avaritia (avarice/greed)
4.acedia (sloth/discouragement)
5.ira (wrath)
6.invidia (envy)
7.superbia (pride)
Human beings are not perfect creatures, and things are rarely black and white. We live in a world of grey, the reason perhaps you mistake it for a smokescreen.
-Removed-The current suit, ACF v Gleeden, or its French equivalent, is in civil court with ACF seeking to have Gleeden restrained from promoting adultery to women.
Women join the site at no cost and then, men pay to contact them for a liaison. While there are questionable aspects, such as whether this is pimping, I fail to see how ACF is harmed, even though its interests are not served by the encouragement of adultery. In addition, Gleeden may have a free-speech case; one might say the case involves the marketplace of ideas.
Now, might a husband bringing suit under the law against an adulterous wife toss in Gleeden as a co-defendant, as well as the man (assuming it is a man) involved? But what would he sue for? What remedy would he seek?
