There are plenty of busy executives at Rupert Murdoch’s scandal-plagued News Corporation, but probably not many with a slate as full as Gerson Zweifach’s. The in-house attorney has been with News Corp. for less than a year, but already he’s been promoted to general counsel, then put in charge of the company’s internal investigation into phone-hacking allegations, and on Wednesday he was named chief compliance officer, as part of a company-wide anticorruption review.

The internal investigation, originally headed by former New York City schools chancellor Joel Klein, was launched after allegations that the now-shuttered News of the World tabloid had hacked into voicemail accounts to further its news-gathering operations. In June, News Corp. put the investigation into the GC’s hands and moved Klein to manage the company’s education business unit.

The anticorruption review is a separate, though certainly related, matter. U.K. newspaper The Guardian, in a report on the review, noted that “News International’s broad internal anti-corruption review began officially in July last year, when Tom Mockridge replaced Rebekah Brooks as chief executive.” Brooks was formally charged by the British government in July, in connection with the phone-hacking case.

The Associated Press reported that Zweifach and vice-president and associate general counsel Lisa Fleischman “are to head a compliance and ethics program and report regularly to the board of directors.” The article also notes that the company “will appoint five compliance officers to oversee each of the company’s two operating units in Los Angeles; its Europe and Asia group; its Australia group; and its New York news and information group.”

In announcing the anticorruption probe and Zweifach’s new CCO position, Murdoch sent a memo to News Corp. employees, which The Guardian posted on its website. In the memo, Murdoch notes the “intense scrutiny” the company is under and says the latest moves are part of an effort to “co-operate with law enforcement officials and strengthen our compliance and ethics programme company-wide.”

Murdoch goes on to say:

The purpose of this review is to test our current internal controls and identify ways in which we can enhance them. Let me emphasize that the review is not based on any suspicion of wrongdoing by any particular business unit or its personnel. Rather, it is a forward-looking review based on our commitment to improve anti-corruption controls throughout the company.

We recognise that strengthening our compliance programmes will take time and resources, but the costs of non-compliance—in terms of reputational harm, investigations, lawsuits, and distraction from our mission to deliver on our promise to consumers—are far more serious.

In handing off the compliance review to the GC, News Corp. did not provide any estimates for when the review would be completed or what sort of action might be taken, beyond saying that Zweifach and Fleischman “will report regularly to the board of directors and the audit committee regarding the content and operation of the compliance and ethics programme.”
