After the end of his full-time political career in 2006, Taormina became one of the main commentators for the Italian sports talk program Il processo di Biscardi.

[2] During his career as a lawyer, Taormina worked on many famous cases, including among others the Itavia Flight 870 accident, where he defended the officials accused of hiding valuable information that could have defined the causes of the incident;[1] the Ardeatine massacre, where he defended ex-SS captain Erich Priebke, alongside Velio Di Rezze and Paolo Giachini, on the grounds that "[Priebke] obeyed an order he considered legitimate and for this reason after many years he did not regret it, but considered the fact as a horror";[1] the murder of Marta Russo, where he lodged a complaint against the magistrates and investigators, without having any connection with the defence of the accused Giovanni Scattone, Salvatore Ferraro, and Francesco Liparota;[1] the Cogne homicide, where he substituted professor Carlo Federico Grosso in the defence of Annamaria Franzoni, and was subsequently substituted by lawyer Paola Savio;[1] the homicide of SISMI agent Nicola Calipari in Baghdad, where he presided as the defender of Gianluca Preite;[1] and the murder of Yara Gambirasio,[1] where he took part as a private citizen to the process arguing for a re-examination of the DNA found on the crime scene to grant Massimo Giuseppe Bossetti, at the time facing life in prison, a more revision of his trial.

[1] He also defended the Sacra Corona Unita boss Francesco Prudentino,[1] and was the lawyer of Franco Freda,[1] a neo-fascist, in the court case for the disbandment of the far-right political party National Front.

He further defended Mario Placanica, a carabiniere accused of the murder of Carlo Giuliani during the Group of Eight meetings in Genova in 2001, Nicola Di Girolamo during his trial for the criminal association for money laundering on an international level and the infraction of the electoral law, as well as of mafia association in 2010, and Franco Fiorito in the scandal for peculation by the Regional Council of Lazio headed by Renata Polverini during September 2012.

Ex-Nuclei Armati Rivoluzionari member Luigi Aronica, Biagio Passaro (leader of the IoApro movement), and Pamela Testa were arrested for the assault on the CGIL headquarters during the No Green Pass demonstration on 9 October 2021.

[2][14] In regards to his political activities during these years and being Silvio Berlusconi's secretary and private lawyer, Taormina declared: "I would never do many things I did back then.

"[15] In 2001, Taormina was briefly state undersecretary to the Ministry of the Interior in the second Berlusconi government;[2] he resigned after six months on 5 December 2001, when the press pointed to his role as deputy secretary "for matters relating to the coordination of anti-racketeering and anti-usury initiatives, and the coordination of solidarity initiatives for the victims of mafia-type crimes", which was in a conflict of interest with the exercise of legal defence in favour of various defendants for mafia events and in criminal trials in which the state had formed a civil party.

In particular, the episode in which he presented himself as the legal defender of the Sacra Corona Unita boss Francesco Prudentino caused a sensation,[1] accompanied by the escort he was entitled to as a state undersecretary of the Ministry of the Interior.

[1] He said: "The time has come for Prodi, Fassino, and Dini to suffer the consequences of the most devastating corruption that has ever been consumed in the history of the Republic and the Judicial offices must also behave accordingly by arranging these characters for arrest.

[21] In September 2003, following the investigations of La Repubblica,[1] Taormina made amends and announced his withdrawal from political life, although he remained in the Italian Parliament for the remainder of the legislature until 2006.

Through the various processes indicated by Repubblica and for my relationships with characters such as D'Andria, Fracassi, Di Bari, and also Francesco Pazienza, all connected by the collective imagination to diverted secret services and to international scams and money laundering, I managed to reach the aim to put the Telekom Serbia Commission to be subject to a poisoned meatball.

[30] According to Taormina, Berlusconi pressed for the approval of the short trial as a threat to raise the price and obtain the law on the legitimate impediment.

This rule, which according to Taormina is "clearly unconstitutional" in that "the precondition for impediment is a charge", is explicitly temporary to allow the approval of the Lodo Alfano as a constitutional law.

[15] In 2011, Taormina was appointed prince regent of Filettino, a municipality in the Frosinone area whose mayor, in reaction to the decision to cut the number of comuni as part of the financial budget law of the fourth Berlusconi government, started a secessionist movement.

[32] In an interview with the radio program La Zanzara in 2013, Taormina replied that the greatest criminal he had defended was a former Christian Democracy member of Parliament that by then was no longer in politics.

[33] In 2017, Taormina was one of the many signers of the appeal of the newspaper Il Tempo asking for release, with postponement and suspension under penalty of health reasons, in favour of the former parliamentarian Marcello Dell'Utri, who was sentenced for external competition in mafia association and other crimes minors.

[1] In a Facebook post, Taormina wrote: "After having always voted and supported M5S, yesterday I formalized my membership in the movement to make a contribution to the only political force legitimized to overthrow this Renzusconian regime [a play of word between the then Italian prime minister Matteo Renzi and Berlusconi].

"[38] He later further specified that he did not want to return to active politics and preferred to continue his career as a lawyer, supporting Beppe Grillo's movement as a private citizen.

[1] In 2020, Taormina filed a complaint against the second Conte government for its alleged failure to apply timely prophylactic action against the COVID-19 pandemic in Italy.

[46][47] On 12 October 2021, Taormina was the lawyer for the five arrested, including the two leaders of New Force, following attacks that took place in a No Green Pass demonstration in which he was also present.

"[48] On 2 August 2022, Taormina announced his candidacy in Lazio for the 2022 Italian general election with South calls North,[1] the political party of Cateno De Luca.

"[52][nb 1] When Berlusconi died in June 2023, Taormina put him alongside Italy's most famous statesmen, such as Alcide De Gasperi, Aldo Moro, Giulio Andreotti, and Bettino Craxi.

"[53] Since 2007, Taormina participates as an association football commentator on the sports broadcast Il processo di Biscardi,[54][55] distinguishing himself both for his AS Roma faith and for his aversion to Juventus.

[61] In 2008, Taormina said that, as a lawyer, the actions of Juventus lawyer Cesare Zaccone, who had told the judge Cesare Ruperto that relegation to Serie B was appropriate punishment (although in reality Zaccone merely meant to say that Juventus did not deserve any punishment further than the other clubs, all of which were eventually saved from relegation, his actions came to be seen an guilty admission or plea deal request) as "very serious".

"[62][nb 3] In 2011, Taormina presented a denounce to Rome's Public Prosecution Office, alleging match fixing in association football.

[70][71][nb 6] In March 2024, Taormina commented on the Francesco Acerbi–Juan Jesus racist case, saying that he was not surprised, and explained: "The [Italian Football] Federation's position on the subject has always been very reliable, the first actions had already made it clear that we would move towards this line.

"[72] Acerbi, who had apologized to Jesus but then retracted, was acquitted due to a lack of evidence, although Serie B and Serie C's precedents pointed to at least a 10-match ban even with lack of evidence,[nb 7] and two rulings from the Italian Football Federation's supreme court (the National Federal Tribunal), including a united section one, held that it is sufficient to believe the victim as long as their testimony is credible.

[74][75][nb 9] The Bergamo Labour Court, following the appeal filed by the Advocate Association for LGBTI Rights – Lenford Network considered that Taormina's expressions were, as discriminatory towards homosexuals, suitable to dissuade certain subjects from submitting their candidacies to professional study and therefore likely to hinder their access to work or make it more difficult, in violation of the rules protecting equal treatment in terms of employment and working conditions.
