Silvio Berlusconi has been denied an application to move his case where he has been accused of having sex with an under-aged prostitute to a special tribunal for ministers in Rome, the BBC reported.

The sex case known as the Ruby sex trial is one of four cases Berlusconi faces for corruption and abuse of power. He denies the charges and claims the Milan court is biased against him.

 The Ruby case has drawn the most international attention after he was accused of paying for sex with the 17-year-old prostitute and later trying to get her out of jail after she was arrested for theft.

While it is not illegal to hire a prostitute in Italy, it is against the law to have sex with any persons under the age of 18, where offenders could face a prison sentence.

Judge Giulia Turri has rejected all defense motions put out by the Italian Prime Minister and rescheduled the next hearing for Oct.3.

Separately, he is also fighting charges of bribing British lawyer David Mills to secure favorable testimony in legal cases, according to CNN. Mills denied receiving bribes and his conviction in the case was overturned last year.
