(Adds Campbell comment, paragraph 3)
By Svea Herbst-Bayliss and Tom Hals
NEW YORK, Oct 25 (Reuters) - Activist investor Third Point LLC sued Campbell Soup Co on Thursday, alleging the soup and snack maker's board misled investors about the competence of its directors and the way it carried out a recently completed strategic review.
The lawsuit is the latest move in a bitter proxy contest in which billionaire investor Dan Loeb and his Third Point hedge fund wants to replace Campbell's 12-member board so it can appoint its own directors and try to revitalize the company's growth.
“We are vigorously contesting the Third Point lawsuit,” Campbell said on Thursday.
In a lawsuit filed in state superior court in Camden, New Jersey, which is Campbell's hometown, Third Point said Campbell and its board "breached their fiduciary duties to Campbell's stockholders by withholding material information critical to stockholders assessing how to vote at the company's annual meeting."
It asked the court to prevent Campbell from holding its annual meeting on Nov. 29 until the board corrects what Third Point called its misstatements. A hearing is scheduled for Tuesday.
Three heirs of condensed soup inventor John Dorrance, who ran the company a century ago, sit on the board and are seeking re-election. Together they control 37 percent of Campbell's stock. Third Point has asked the court to postpone shareholders' votes on the board until the company corrects what Third Point described as misinformation by the board.
The lawsuit said the company failed to disclose critical information about its directors, including Dorrance's grandchild Bennett Dorrance. It accused the company of not making adequately clear what Dorrance's business ventures and investments were, among other things.
Dorrance did not immediately respond to a telephone message seeking comment.
The company's shares closed down 1.1 percent at $37.95 on Thursday, down more than 20 percent since the start of the year.
Earlier on Thursday, Campbell's board chairman wrote a letter to investors saying that Third Point's proposed directors were not qualified to oversee the company and that Third Point had not presented any new ideas or specific strategic plan.
"Third Point has, at best, a superficial understanding of the food industry and the company, as evidenced by its non-substantive plan filled with platitudes and business school buzzwords," the letter to shareholders said.
Lawsuits are not uncommon in proxy battles as both sides seek every advantage. Third Point said in the suit that it needed the court's help to wage a "meaningful proxy contest" and for investors to make fully informed decisions.
Such cases are difficult for activist investors to win, said Kai Liekefett, a partner who heads law firm Sidley Austin's activist defense practice. But merely bringing the case could offer advantages.
"Third Point might be hoping to obtain damaging and embarrassing documentation such as emails during discovery. This worked well for them in the Sotheby’s proxy contest," where the hedge fund was given three board seats in 2014, he added.
Third Point said in its lawsuit that shareholders did not have enough information to assess the company's strategic plans, which includes selling some divisions and finding a permanent chief executive to replace Denise Morrison, who left in May.
"Without further information about its strategic plan that the board has withheld, and that is unknowable to stockholders without further disclosure, the Nov. 29 director election will be a sham," the lawsuit said.
