Yes, because he tapped a phone that he probably shouldn't have and isn't he appealing? That he has a 'proven' record of inventing stuff and that his theories are improbably is just your opinion. Would his theories indeed have been improbable then that only would have been good for the defense. The crazier his theories the more likely that the judges would reject them. I don't see the point. He is just doing his job. It is the judges that decide.
Quite the opposite actually
The bench ruled that he and Michele Giuttari, a detective-turned-thriller writer, had used
their powers to persecute people they regarded as their enemies: tapping their phones, interrogating them, putting them under investigation without any evidence against them and even getting them jailed, for personal reasons
the court said, were guilty of "almost unheard of" criminal activity,
carrying out investigations "in no way related ... to their proper competence", launching criminal cases with no evidence, ordering phone taps with "quite different ends" from those cited when the taps were authorised, taps that were made "for reasons of retaliation ... against people towards whom they had reasons for hostility".

Even though all the Monster's victims were shot with the same gun, Mignini told a court that it wasn't the work of a single serial killer. Rather,
Mignini described an elaborate conspiracy of 20 people, including government officials and law enforcement officers, who made up a secret society behind the Monster killings.
Mignini indicted the 20 people and charged them with the concealment of Narducci's murder, and laid out a hard-to-follow plot that included body doubles and featured Narducci's body being swapped - not once, but twice!
If all of this sounds hard to believe, it is. Tuesday, in a preliminary hearing, Perugia Judge Paolo Micheli threw out the case against the 20. The judge found there was no solid evidence to back up Mignini's claim that Narducci was murdered, let alone the victim of a satanic sect
Late Tuesday evening, when the 20 defendants were freed of all charges, they celebrated in front of the courthouse, opening bottles of champagne
a court in Florence said Mignini was guilty of abusing the considerable powers of his office
According to the Italian newsmagazine Panorama, investigators discovered that
Mignini maintained computer lists entitled "Attacks to Remember" and "Orgy of Attacks." The lists contained names of journalists, government officials, and members of the Italian Parliament.
Mignini was convicted of
launching investigations into his critics in the media, the police, and the government. The prosecutor illegally wiretapped phones and cell phones in his ambition to end the "orgy of attacks."
Because he violated the public trust, the Florence court banned Mignini from holding public office for the rest of his life. But, during his appeal, the prosecutor gets to remain in office. Mignini has not been called on to resign either

He was convicted of:
1.) Illegally investigating journalists who had criticized him with the "intent to harass or deter them from pursuing their legitimate profession". Specifically the court found that Mignini had targeted Italian journalists Vincenzo Tessandori, Gennaro De Stefano, and Roberto Fiasconaro, because they had criticized his investigations into the death of Narducci.
2.) Ordering an illegal investigation of the Florentine ex police chief Giuseppe De Donno.
3.) Ordering illegal investigations of two officials of the Viminale, the Ministry of the Interior in Rome, including an illegal investigation of the Roberto Sgalla, ex-director of the office of external affairs
