Two female whistle-blowers gave evidence to American lawyer Michael Garcia, who over 18 months investigated the bidding process of the 2018 and 2022 World Cups.The women claim Garcia ensured they would have anonymity in his investigative report -- and that he broke his promise.It's a report that has become mired in controversy after German judge Hans-Joachim Eckert -- FIFA's independent ethics adjudicator -- published a summary of the evidence the American had collated."Our cooperation was facilitated by Mr Garcia's repeated promises - made privately to us and also in public - to ensure the confidentiality of his witnesses," said Bonita Mersiades and Phaedra Al-Majid in a joint statement."He said the report would not be published; that only four people would see it; and that the identities of the people he spoke with -- other than current serving football officials or employees -- would remain confidential."This was a crucial element behind our decision to cooperate, as we are private citizens and no longer protected by the legal and PR functions of wealthy football federations."AssurancesThe two women insist that assurances were given to them both in private and public that they would not be compromised after agreeing to give evidence "through a sense of natural justice and a desire to bring closure to a long running chapter in our lives."The women were not identified by name, but they contend they were "clearly identifiable" in Eckert's summary.Garcia's office declined to respond to CNN's request for a response to the women's statement, while FIFA has said its disciplinary committee will investigate the duo's claims.Former head of corporate affairs in the Australia 2022 bid, Mersiades told CNN that Garcia - FIFA's independent ethics investigator -- made a verbal promise to her "more than once" that the report would not be published.In September Garcia said for the first time that his report should be made public with redactions.Soon after its publication, Garcia said the 42-page summary contained "numerous materially incomplete and erroneous representations." According to FIFA, Garcia and Eckert are due to meet on Thursday to discuss their differences.The bidding process surrounding the 2018 and 2022 events has become a lightning rod for criticism of the way FIFA is run.The organization had hoped the report's publication would put in an end to the intensive scrutiny FIFA has faced. But Garcia's negative reaction to Eckert's summary and the two whistleblowers' subsequent complaints make that seem unlikely.In a statement, FIFA told CNN that "any potential breach of confidentiality committed by a member of the FIFA Ethics Committee should be examined by the FIFA Disciplinary Committee."It added: "We cannot prejudice any decision that said Committee could take in this or any similar situation. However, names of witnesses have not been disclosed in the statement of the Chairman of the Adjudicatory Chamber of the FIFA Ethics Committee to protect their personality rights."Furthermore, the discussion and the public letter by Phaedra Al-Majid and Bonita Mersiades underline exactly the confidentiality issue concerning any of the witnesses when talking about a publishing of the full report."Eckert's report cleared Russia and Qatar, who will stage the 2018 and 2022 events respectively, of wrongdoing and instead was critical of rival bidders England and Australia.Bakudaily.Az
