In a statement today, NAV said the investigation, which together with its annex comes to 1,200 pages, established that the whistleblower had wrongly claimed that the tax office had failed to take action against tax cheats.

The statement said that an investigation of the former employee’s allegations had been necessitated since Horváth’s charges had lacked a factual basis. “Given the allegations based on his experience at the tax office were not underpinned by concrete evidence”, the sources of these experiences had to be examined point-by-point, and responses given to the question of whether any abuses had taken place, the statement said.
