(ANSA) -Ancona, January 19 - A Rome judge has dismissed a defamation suit filed by Campania Governor Vincenzo De Luca against anti-mafia commission chair Rosy Bindi after he was included on a list of 17 crime-tainted candidates in 2015 regional elections. Preliminary judge Giovanni Giorgianni shelved the suit at the request of the public prosecutor, despite De Luca's opposition. De Luca said in May he was suing Bindi after the parliamentary commission she chairs included him in the list of candidates deemed unfit to stand in the polls. He was convicted in January 2015 of abuse of office in connection with an incinerator project while he was mayor of the city of Salerno, and handed a suspended sentence of a year in prison plus a one-year ban from holding public office. As a result of the conviction, he was also suspended from holding public office for 18 months under a 2012 anti-corruption law known as the Severino law but the Campania Regional Administrative Tribunal (TAR) reinstated him three days later. The dismissal measure filed on Tuesday said it was clear that the decisions taken by the anti-mafia commission had been widely backed by the parliamentary groups it is made up of.
