ROME, May 30 (UPI) -- Italy's highest appeals court has ruled in a 33-year-old case that wives forfeit their rights to shared assets if they use their marital beds for infidelities.

The Cassation Court ruled the plaintiff, identified as Aldo, is not required to split shared assets with his ex-wife, Silvana, because she committed "a grievous injury which seriously damaged Aldo's moral patrimony" by using her marital bed for trysts with a lover, ANSA reported Friday.

The judges said Silvana displayed a "deceitful and disrespectful attitude" with her behavior.

The decision upheld an appeals court's 2005 decision in Aldo's favor. The court had overturned a 1990 ruling by a court that sided with Silvana.
