Former Las Vegas Sands president and COO William Weidner may be the most accomplished gaming executive still in the business. Weidner’s 14 years with LVS included building its Vegas Strip Venetian complex, gaining entry to Macau, developing Cotai as world’s most lucrative casino cluster, winning a license in Singapore and conceiving what’s become the world’s most admired integrated resort there. So Weidner provided instant credibility when he joined Canadian private equity investor Clairvest’s effort to win an integrated resort license in Wakayama Prefecture near Osaka.

Perhaps, then, it shouldn’t be surprising that Weidner came under attack via anonymous documents recounting legal settlements of US government charges against Las Vegas Sands during his tenure. The documents may aim to weaken Wakayama’s IR bid, but it’s equally likely they stem from a long running dispute involving Weidner’s Global Gaming Asset Management firm and Philippine billionaire Enrique Razon’s Bloomberry Resorts, or a Taiwan’s American Asian Entertainment’s US$12 billion lawsuit against LVS over termination of their Macau partnership, in which Weidner was a leading actor but is not a party to the litigation.

In any case, the attack is another ugly aspect of Japan’s casino legalization saga that has limited public support and gotten the cold shoulder from leading international casino companies and Japan’s largest cities and tourist destinations.
