Marianne and Jaillette were sentenced for defamation for denigrating Prof Séralini and his 2012 research study showing that Roundup and GMO maize caused ill health effects in rats, including liver and kidney damage and hormonal disturbances.
The study was retracted by the first journal that published it after a sustained campaign of defamation by lobbyists. It was subsequently republished in another peer-reviewed journal.
Jaillette’s defamatory article appeared in Marianne in September 2012, in the same month that Séralini’s study was first published. The article said that “researchers around the world” had voiced “harsh words” about the research, which it called a “scientific fraud in which the methodology served to reinforce pre-determined results”.
Séralini, his research team, and CRIIGEN challenged this allegation. They were assisted by lawyers Bernard Dartevelle and Cindy Gay.
