An Italian woman who made anonymous calls to her lover's wife to tell her of their affair has been told she must pay a €400 (£287) fine for harassment.
The woman, named locally as Annamaria D.R., also told her lover's wife about other affairs her husband had allegedly been having in Bari and Potenza, southern Italy.
She argued in court during an appeal hearing that because her lover's wife did not hang up on her calls immediately, it was clear she was interested in what was being said.
The mistress tried to overturn a conviction of harassment originally issued by the Court of Potenza in 2013.
However, Italy's Supreme Court in Rome ruled that the fact the wife did not interrupt the calls "cannot be seen as acquiescence on the wife's part, given the serious nature of what was being revealed."
"The petulant and disturbing nature of the calls is shown in the anonymous forms they took," said the ruling.
The court upheld the original conviction of harassment, with judges saying that an anonymous call to reveal an affair is a reprehensible act regardless of whether the claim is true.
