"SAO PAULO - Executives at Vale SA, the world’s largest iron ore miner, quashed efforts by Brazilian authorities to audit one of the company’s mining dams months before it collapsed and killed over 300 people, a state prosecutor was quoted as saying by news website G1 on Wednesday.
William Garcia, a prosecutor in Minas Gerais where the January disaster occurred, told G1 his office had filed subpoenas with Vale last June to review safety documents regarding Vale’s dam.
But Vale’s lawyers responded in November arguing they had received positive reviews of the dam by an auditor the firm had hired, the German firm Tuv Sud, Garcia said. "
