Transparency International calls it »the biggest bribery story of 2012«:
In September 2005, a senior Wal-Mart lawyer received an alarming e-mail from a former executive at the company’s largest foreign subsidiary, Wal-Mart de Mexico. In the e-mail and follow-up conversations, the former executive described how Wal-Mart de Mexico had orchestrated a campaign of bribery to win market dominance. In its rush to build stores, he said, the company had paid bribes to obtain permits in virtually every corner of the country.[…]
In the interviews, Mr. Cicero recounted how he had helped organize years of payoffs. He described personally dispatching two trusted outside lawyers to deliver envelopes of cash to government officials. They targeted mayors and city council members, obscure urban planners, low-level bureaucrats who issued permits — anyone with the power to thwart Wal-Mart’s growth. The bribes, he said, bought zoning approvals, reductions in environmental impact fees and the allegiance of neighborhood leaders.
He called it working “the dark side of the moon.”David Barstow (21.4.2012): Vast Mexico Bribery Case Hushed Up by Wal-Mart After Top-Level Struggle. The New York Times.
