On Friday, an appeals court in Milan overturned the 2013 conviction that found him guilty of paying for sex from 17-year-old nightclub dancer Karimea El-Mahroug.
"The decision goes beyond our rosiest predictions," said Franco Coppi, Berlusconi's attorney, following the announcement.
Both Berlusconi and El-Mahroug denied they engaged in sexual relations, and Berlusconi maintained he didn't know she was a minor. The two met, he said, at a dinner party at his mansion. He admitted that he once phoned a police station regarding El-Mahroug's detention for allegedly stealing cash, but said he didn't press for her release.
In a statement following Friday's appellate court ruling, Berlusconi thanked his supporters.
"I'm deeply moved: only those who stood by me in these past years know what I've suffered for this unjust and infamous accusation."
Berlusconi is currently serving a community service sentence for a separate conviction of tax fraud.
