In Louisiana Municipal Police Employees’ Retirement System v. Crawford, (Del. Ch., Feb. 13, 2007), read letter opinion here, and read Bloomberg summary here, Chancellor Chandler enjoined a vote in order to give shareholders more time to consider a competing bid. There will be much more written about this case, but I wanted to add this tidbit for now.
UPDATE: See the Chancery Court’s more complete decision of Feb. 23 at this link.
