Published in mid-February 2015, the COGEST report on the Giroud case leaves no room for doubt: from start to finish, the Valais authorities acted correctly in their handling of Dominique Giroud's tax case, which did not benefit from any complacency on the part of the tax authorities or any member of the Council of State. Debated by the Grand Council in mid-March 2015, the report was hailed for its quality and all members of parliament agreed that it put an end to the unfounded suspicions that had weighed on Maurice Tornay for almost a year. The next day, journalists were forced to admit that the mountain had given birth to a mouse. All the journalists except one: Marie Parvex, alone against the rest of the world, unable to accept the facts that scream in her face that she was wrong. Marie Parvex adopts the attitude that all journalists who are wrong systematically adopt: she denies the evidence and fabricates alleged grey areas to try to instil doubt and resurrect her thesis, the one she invented in October 2013, the one that led her to hope that, like the great investigative journalists, she had uncovered an affair of state likely to make a minister resign, the thesis that was repeated by all her colleagues for months, the thesis that, incredible as it may seem in retrospect, earned her the most prestigious journalism prize in French-speaking Switzerland, the thesis that, as the COGEST report shows, was simply proven to be false, a thesis that is now defended only by Marie Parvex, in her great solitude. Fortunately, ridicule does not kill - and neither does bad journalism.
