NEW YORK, March 28 (Reuters) - Blackwells Capital is

ratcheting up the pressure on Walt Disney ( DIS ) in a bruising

boardroom battle by suing the entertainment giant in Delaware

court for information that may point to possible disclosure

violations in dealings with hedge fund ValueAct Capital.

The suit is the latest chapter in a fight over who will sit

on Disney's ( DIS ) board and help guide the home of Mickey Mouse in

business and personnel decisions. Blackwells and another hedge

fund, Trian Fund Management, are trying to persuade investors to

elect their director candidates while Disney ( DIS ) is backing its own

directors.
