Piece by piece, Wells Fargo has been revealing how it intends to run Wachovia. Not so fast, some of Wachovia's shareholders are protesting, though they're facing long odds. On Monday, a Charlotte judge is scheduled to hear a shareholder's class-action lawsuit that seeks to block the impending purchase, claiming that Wells is not offering a fair price or allowing a fair vote. A ruling in favor of the shareholders could make way for a higher bidder, force Wells to offer a higher price, or even enable Wachovia to remain an independent company. The outcome also could have broader implications, setting a standard for how much voting power companies can gain and shareholders can lose.
