Two other journalists also complained about the malodorous colleague, saying they too could no longer bear to share with him.
Managers allegedly told them they would lose their jobs, with one commenting: "Any journalist who refuses to be in a room with him should be kicked up the a***."
Mondini took the public broadcaster to court. The case, as so often in Italy's ossified judicial system, has turned into a tortuous legal saga.
It has already dragged on for four years but has come to light again after prosecutors ordered fresh investigations into the complaints.
Case takes mafia-style twist
"Not even in the saucy comedies of the 1970s could we have imagined reading what is being reported from the precious studios of the national broadcaster, amid sniggers, winks, nudges of the elbow and gastrointestinal problems," one Italian commentator wrote on Wednesday.
The persistent "chemical attacks" by one colleague towards another had got the whole country talking, wrote Maurizio De Caro in Affari Italiani.
The case has now taken a new twist, with claims that the flatulent broadcaster had inappropriate contacts with a convicted mafia boss from the Ndrangheta', the organised crime network based in Calabria in southern Italy. The investigation continues.
