The deal for Univision ( UVN) may be done, but anger about the way the auction process was handled lingers.Two shareholder lawsuits against the large Spanish-language broadcaster have already popped up, claiming it breached fiduciary duty when it agreed to sell itself last week. The lawsuits were first reported by The Associated Press. Univision couldn't be reached for comment on Monday. Meanwhile, sources say that Televisa ( TV) and its buyout team -- the second-place finishers in the auction -- were prepared to make a significantly higher bid for Los Angeles-based Univision but never got the chance. Univision last Tuesday agreed to a $12.3 billion, $36.25-a-share acquisition by a group including Madison Dearborn, Thomsas H. Lee Partners, Providence Equity, Texas Pacific and mogul Haim Saban. The losing bidders included Televisa, Bill Gates' Cascade Investment and Bain Capital. That group initially bid $35.75 per share after suffering a number of defections by other equity partners. What remains unclear a week after the deal was announced is why Univision would shut the door on a higher bid if one were in the works. Ending an auction before everyone is done bidding seems counterintuitive, at best. Whether or not that actually happened, shareholder displeasure is evident in the lawsuits. According to the AP, both suits were filed in Los Angeles Superior Court and seek class-action status. One suit seeks to block the sale on grounds that it occurred "at a price that is not fair and equitable" to shareholders. It seeks unspecified damages and says the Univision board put its own personal interests and those of the successful bidder above shareholders and didn't hold an "active and open auction" for the company, according to the AP. For its part, Televisa is steamed, as its recent public comments suggest. Sources say that the company is weighing a number of options, including starting its own network in the U.S.
