Syngenta was rejected by the Court. In May 2010, Syngenta was condemned by the IV Permanent People’s Tribunal for human rights violations in Brazil. Tyrone Hayes There has been a long-running conflict between Syngenta and University of California at Berkeley biologist Tyrone Hayes. According to an article in the 10 February 2014, issue of The New Yorker, Syngenta’s public-relations team took steps to discredit Hayes, whose research is purported to suggest that the Syngenta-produced chemical atrazine was responsible for abnormal development of reproductive organs in frogs. The article states that the company paid third-party critics to write articles discrediting Hayes’s work, planned to have his wife investigated, and planted hostile audience members at scientific talks given by Hayes. During a 21 February 2014, interview conducted on Democracy Now, Hayes reiterated the claims. After the interview aired, Syngenta denied targeting Hayes or making any threats, calling those statements "uncorroborated and intentionally damaging" and demanding a retraction and public apology from Hayes and Democracy Now. In 2010, Syngenta forwarded an ethics complaint to the University of California Berkeley, complaining that Hayes had been sending sexually explicit and harassing e-mails to Syngenta scientists. Legal counsel from the university responded that Hayes had acknowledged sending letters having "unprofessional and offensive" content, and that he had agreed not to use similar language in future communications.
