In a most interesting development, despite earlier promises of transparency, Volkswagen has been very slow to turn over internal documents to regulators investigating the emissions cheating scandal. Volkswagen says that German privacy laws block their disclosure. On Jan. 19, several state attorneys general made this development known. Former Volkswagen CEO Martin Winterkorn had said that the automaker would fully cooperate with agencies “with transparency and urgency.” But attorneys general for New York and Connecticut – which, along with 24 other states, have launched a probe into the scandal – say that the company has been “loath to work” with them, citing German privacy laws behind its refusal to turn over executives’ emails and other documents. It looks like discovery through the civil courts will have to obtain what Volkswagen refuses to turn over.
