An interesting case from France:
France's ruling UMP party has opposed a French court's decision to annul a marriage between two Muslims because the wife lied about being a virgin.
The Lille court's decision has also angered feminists who say it amounts to a fatwa against women's liberty.
The court granted the man's request for an annulment after ruling that he had been tricked into a marriage.
Both conservatives and feminists have joined forces to complain about the decision, but the government response:
....a justice ministry spokesman insisted the court's decision was not based on religion or morality but on the French civil code under which a marriage can be annulled if a spouse has lied about an "essential quality" of the relationship.It sounds like there must be some interesting claims made in applications for annulment in France, then!
In Australia, incidentally, annulment of a civil marriage is exceptionally rare, as it is only available because one party was already married, or under age, or forced into a marriage under duress.
The fact that your partner lied about her sexual history seems an extraordinarily silly thing to consider for annulment.
