Italy's highest court is hearing what could be the final appeal in former Premier Silvio Berlusconi's infamous "bunga-bunga" case.

The Court of Cassation will decide whether or not to make final Berlusconi's acquittal by an appellate court on charges of paying for sex with an underage prostitute during sex-fueled parties at his Milan villa, and using his influence to cover it up. A lower court had convicted the three-time former premier of both charges, and sentenced him to seven years.

The high court can decide to uphold the acquittal or throw it out, ordering a new appeals trial. A decision is expected later Tuesday.

Berlusconi last week completed his community service stint for a tax fraud conviction. He immediately threw himself back into politics ahead of regional elections in May.
