Shares of Wynn Resorts tumbled on January 12 when it came out that a Wynn director and major shareholder had filed a lawsuit against the casino company. Turns out Kazuo Okada, one of Steve Wynn’s original partners, is claiming the company made a questionable $135 million donation to the University of Macau and hasn’t been sharing its financial information with him. Reuters has a nice write-up here.

The veiled implication is Wynn’s sizable donation might have been less than philanthropic — bordering on a “pay to play” ante to retain favor in the world’s most lucrative gaming destination. (The competing Las Vegas Sands’ Macau operation is currently under DOJ and SEC scrutiny for possible infringement of the Foreign Corrupt Practices Act, as referenced here in a Wall Street Journal blog.)

Wynn claims Okada’s lawsuit is just a smoke screen to mask the fact that Okada had been working behind Wynn’s back to develop a casino in the Philippines. You can read all the tawdry details in A Partners’ Fight Erupts at Wynn.

How will it end? Perhaps better than Steve Wynn’s marriage. After all, Wynn recently told the press, “I love Kazuo Okada as much as any man that I’ve met in my life.”

Wynn shares have since recovered from the drama at the start of January, but still have a ways to go in 2012 before reaching 2011 highs.
